5 S99TE Introduction Ballscrews, also called a ball bearing screws, recirculating ballscrews, etc., consist of a screw spindle and a nut integrated with balls and the balls return mechanism, return tubes or return caps. Ballscrews are the most common type of screws used in industrial machinery and precision machines. The primary function of a ballscrew is to convert rotary motion to linear motion or torque to thrust, and vice versa, with the features of high accuracy, reversibility and efficiency. HIWIN provides a wide range of ballscrews to satisfy your special requirements. The combination of state-of-the-art machining technology, manufacturing experiences, and engineering expertise makes HIWIN ballscrew users High-Tech Winners. HIWIN uses precise procedures to create exact groove profiles, either by grinding or precision rolling. Accurate heat treatment is also used to ensure the hardness of our ballscrews. These result in maximum load capacity and service life. HIWIN precision ballscrews provide the most smooth and accurate movement, together with low drive torque, high stiffness and quiet motion with predictable lengthened service life. HIWIN rolled ballscrews also provide smooth movement and long life for general applications with less precision in lower price. HIWIN has modern facilities, highly skilled engineers, quality manufacturing and assembly processes, and uses quality materials to meet your special requirements. It is our pleasure to provide you with the technical information and selection procedure to choose the right ballscrews for your applications through this catalogue. 2 Technological Features of HIWIN Ballscrews 2.1 Characteristics of HIWIN Ballscrews There are many benefits in using HIWIN ballscrews, such as high efficiency and reversibility, backlash elimination, high stiffness, high lead accuracy, and many other advantages. Compared with the contact thread lead screws as shown in (Fig. 2.1), a ballscrew add balls between the nut and spindle. The sliding friction of the conventional screws is thus replaced by the rolling motion of the balls. The basic characteristics and resultant benefits of HIWIN ballscrews are listed in more details as follows: Ballscrew ACME Screw P.C. O R O P.C. R Fig 2.1 Basic configuration of ballscrews and contact thread lead screws

6 2 S99TE15-81 (1) High efficiency and reversibility Ballscrews can reach an efficiency as high as 9% because of the rolling contact between the screw and the nut. Therefore, the torque requirement is approximately one third of that of conventional screws. It can be seen from Fig. 2.2 that the mechanical efficiency of ball screws are much higher than conventional lead screws. HIWIN ballscrews have super surface finish in the ball tracks which reduce the contact friction between the balls and the ball tracks. Through even contact and the rolling motion of the balls in the ball tracks, a low friction force is achieved and the efficiency of the ballscrew is increased. High efficiency renders low drive torque during ballscrew motion. Hence, less drive motor power is needed in operation resulting in lower operation cost. HIWIN uses a series of test equipment and testing procedures to guarantee the efficiency.

Backlash is eliminated by our special designed othic arch form balltrack (Fig. 2.3) and preload. In order to achieve high overall stiffness and repeatable positioning in CNC machines, preloading of the ballscrews is commonly used. However, excessive preload increases friction torque in operation. This induced friction torque will generate heat and reduce the life expectancy. With our special design and fabrication process, we provide optimized ballscrews with no backlash and less heat losses for your application Semi Circular Type othic Type Fig2.3 Typical contact types for ballscrews (3) High lead accuracy For applications where high accuracy is required, HIWIN modern facilities permit the achievement of ISO, JIS and IN standards or specific customer requirements. This accuracy is guaranteed by our precise laser measurement equipment and reported to each customer. (4) Predictable life expectancy Unlike the useful life of conventional screws which is governed by the wear on the contact surfaces, HIWIN s ballscrews can usually be used till the metal fatigue. By careful attention to design, quality of materials, heat treatment and manufacture, HIWIN s ballscrews have proved to be reliable and trouble free during the period of expected service

7 S99TE life. The life achieved by any ballscrew depends upon several factors including design, quality, maintenance, and the major factor, dynamic axial load (C). Profile accuracy, material characteristics and the surface hardness are the basic factors which influence the dynamic axial load. It is recommended that the life at average axial load should be a minimum of 1x1 6 revs). High quality ballscrews are designed to conform with the B rating (i.e. 9% probability of achieving the design life). Fifty percent of the ballscrews can exceed 2 to 4 times of the design life. (5) Low starting torque and smooth running ue to metal to metal contact, conventional contact thread lead screws require high starting force to overcome the starting friction. However, due to rolling ball contact, ballscrews need only a small starting force to overcome their starting friction. HIWIN uses a special design factor in the balltrack (conformance factor) and manufacturing technique to achieve a true balltrack. This guarantees the required motor torque to stay in the specified torque range. HIWIN has special balltrack profile tracing equipment to check each balltrack profile during the manufacturing process. A sample trace is shown in Fig HIWIN also uses computer measurement equipment to accurately measure the friction torque of ballscrews. A typical distance-torque diagram is shown in Fig H-MA:2 Y-MA: Work name : S.H Measure node: X pitch Pick up radius:.256mm Model No. : 1H-2-3 Horizontal mag: 2. Lot No. : Vertical mag: 2.

8 4 S99TE15-81 (6) Quietness High quality machine tools require low noise during fast feeding and heavy load conditions. HIWIN achieves this by virtue of its return system, balltrack designs, assembly technique, and careful control of surface finish and dimensions. (7) Short lead time HIWIN has a fast production line and can stock ballscrews to meet short lead times. (8) Advantages over hydraulic and pneumatic actuators The ballscrew used in an actuator to replace the traditional hydraulic or pneumatic actuator has many advantages, i.e. fast response, no leakage, no filtering, energy savings and good repeatability.

9 S99TE Classification of Standard Ballscrews 3.1 Standard Ballscrew Spindle HIWIN recommends our standard regular ballscrews for your design. However, high lead, miniature or other special types of ballscrews, may also be available upon your request. Table 3.1 shows the standard ballscrew spindles which are available. 3.2 Nut Configuration (1) Type of return tube design HIWIN ballscrews have three basic ball recirculation designs. The first, called the external recirculation type ballscrew, consists of the screw spindle, the ball nut, the steel balls, the return tubes and the fixing plate. The steel balls are introduced into the space between the screw spindle and the ball nut. The balls are diverted from the balltrack and carried back by the ball guide return tube form a loop. Since the return tubes are located outside the nut body, this type is called the external recirculation type ballscrew Fig The second design, called the internal recirculation type ballscrew, consists of the screw spindle, the ball nut, the steel balls and the ball return caps. The balls make only one revolution around the screw spindle. The circuit is closed by a ball return cap in the nut allowing the balls to cross over adjacent ball tracks. Since the ball return caps are located inside the nut body, this is called the internal recirculation type ballscrew Fig Fig3.1 External recirculation type nut with return tubes Fig3.2 Internal recirculation type nut with return caps The third design is called endcap recirculation type ballscrew Fig The basic design of this return system is the same as the external recirculation type nut Fig. 3.4 except that the return tube is made inside the nut body as a through hole. The balls in this design traverse the whole circuit of the balltracks within the nut length. Therefore, a short nut with the same load capacity as the conventional design can be used. Table 3.1: HIWIN standard ballscrew spindle and lead Fig3.3 Endcap recirculation type nut with return system unit : mm Type Miniature Regular High lead Super High Lead dia. lead * : Precision ground grade ballscrews, either left-hand or right-hand screws are available.

10 6 S99TE15-81 (2) Type of nuts The type of nuts to select depends on the application requirements. HIWIN standard nuts are classified by three letters as follows (see also Chapter 5 for details): Flange Type (F) Round Type (R) Single-Nut (S) ouble-nut () Single-Nut (S) ouble-nut () Internal Return Cap (I) External Return Tube Endcap (H) Internal Return Cap (I) External Return Tube Endcap (H) Tube within the Nut ia. (W) Tube above the Nut ia. (V) Tube within the Nut ia. (W) Tube above the Nut ia. (V) * Other types of nut shape can also be made upon your design. The special high-lead double-start nut is classified by adding in front of the above three letters. The compression preload nut is classified by adding P in front of the above three letters. The offset pitch preload single nut is classified by adding O in front of the above letters. Examples : RI means round type, double nut with internal return caps. FSW means flange type, single nut with external return tube within the nut diameter. FSV means two-start, flange, single nut with external return tube above the nut diameter. (3) Number of circuits The HIWIN nomenclature for the number of circuits in the ballnut is described as follows: For the external type design: A : 1.5 turns per circuit B : 2.5 turns per circuit C : 3.5 turns per circuit : 4.5 turns per circuit E : 5.5 turns per circuit For the internal type design: T : 1. turn per circuit For end cap type design: U : 2.8 turns per circuit (high lead) S : 1.8 turns per circuit (super high lead) V :.7 turns per circuit (extra high lead) For Super S Series: Fig 3.4 Circuit for external return tube K : 1 turn per circuit Example : B2 : designates 2 external return tube ball circuits. Each circuit has 2.5 turns. T3 : designates 3 internal return ball circuits. Each circuit has a maximum of 1 turn. S4 : designates 4 internal return ball circuits. Each circuit has 1.8 turns. K5 : designates 5 internal return ball circuits. Each circuit has 1 turn. HIWIN recommends that number of circuits for the external type design be 2 for 2.5 or 3.5 turns ( that is, B2 or C2), and 3, 4 or 6 circuits for the internal type. Those shapes are shown in Fig. 3.4 and Fig Fig 3.5 Circuit for internal return cap

11 S99TE Spindle End and Journal Configuration Mounting methods Bearing mounting methods on the end journals of ballscrews are crucial for stiffness, critical speed and column buckling load. Careful consideration is required when designing the mounting method. The basic mounting configuration are shown as follows Fig Spindle end journal configurations The most popular journal configurations are shown in Fig Table 3.2 lists the recommended dimensions and the bearings for the configurations of Fig Table 3.2 imension for spindle ends Model d1 d5 d6 d7 d8 E L3 L4 L5 L6 L7 L8 L9 L1 L11 L12 L13 bxt1 * We reserve the right to modify and improve data value without prior notice. * ifferent diameters and leads are available upon request.

13 S99TE esign and Selection of HIWIN Ballscrews 4.1 Fundamental Concepts for Selection & Installation (1) A ballscrew must be thoroughly cleaned in white spirit and oil to protect against corrosion. Trichloroethylene is an acceptable degreasing agent, ensuring the ball track free from dirt and damage (paraffin is not satisfactory). reat care must be taken to ensure that the ball track is not struck by a sharp edged component or tool, and metallic debris does not enter the ball nut (Fig. 4.1). (2) Select a suitable grade ballscrew for the application (ref. Table 4.5). Install with corresponding mounting disciplines. That is, precision ground ballscrews for CNC machine tools demand accurate alignment and precision bearing arrangement, where the rolled ballscrews for less precision applications, such as packaging machinery, require less precise support bearing arrangement. It is especially important to eliminate misalignment between the bearing housing center and the ballnut center, which would result in unbalanced loads (Fig. 4.2). Unbalanced loads include radial loads and moment loads (Fig. 4.2a). These can cause malfunction and reduce service life (Fig.4.2b).

14 1 S99TE15-81 (3) To achieve the ballscrews maximum life, recommend the use of antifriction bearing oils.oil with graphite and MoS 2 additives must not be used. The oil should be maintained over the balls and the balltracks. (4) Oil mist bath or drip feeds are acceptable. However, direct application to the ball nut is recommended (Fig. 4.3). (5) Select a suitable support bearing arrangement for the screw spindle. Angular contact ball bearings (angle=6 ) are recommended for CNC machinery. Because of higher axial load capacity and ability to provide a clearance-free or preloaded assembly (Fig. 4.4). uplex F Triplex TF Quadruplex TF Quadruplex TB Fig 4.4 ifferent arrangement of ballscrew support bearings (6) A dog stopper should be installed at the end to prevent the nut from over-travelling which results in damage to ballscrew assembly (Fig 4.5). (7) In environments contaminated by dust or metallic debris, ballscrews should be protected using telescopic or bellowtype covers. The service life of a ballscrew will be reduced to about one-tenth normal condition if debris or chips enter the nut. The bellow type covers may need to have a threaded hole in the flange to fix the cover. Please contact engineers when special modifications are needed (Fig 4.6). Fig 4.5 A dog stopper to prevent the nut from over travelling Fig 4.6 Ballscrew protection by telescopic or bellow type covers (8) If you select an internal recirculation type or an endcap recirculation type ballscrew, one end of the ball thread must be cut through to the end surface. The adjacent diameter on the end journal must be.5 ~ 1. mm less than the root diameter of the balltracks (Fig 4.7). (9) After heat treating the ballscrew spindle, both ends of the balltracks adjacent to the journal have about 2 to 3 leads left soft, for the purpose of machining. These regions are shown in (Fig. 4.8) with the mark on HIWIN drawings. Please contact engineers if special requirements are needed in these regions. dr (root dia).5~1.mm less than dr Fig 4.7 Special arrangement for the end journal of an internal recirculation screw Fig 4.8 The heat treatment range of the ballscrew spindle

15 S99TE (1) Excessive preload increases the friction torque and generates heat which reduces the life expectancy. But insufficient preload reduces stiffness and increases the possibility of lost motion. Recommends that the maximum preload used for CNC machine tools should not exceed 8% of the basic dynamic load C. (11) When the nut needs to be disassembled from/assembled to the screw spindle, a tube with an outer dia..2 to.4 mm less than the root diameter (ref. M37) of the balltracks should be used to release/connect the nut to from/to the screw spindle via one end of the screw spindle shown in Fig (12) As shown in Fig 4.1, the support bearing must have a chamfer to allow it to seat properly and maintain proper alignment. HIWIN suggests the IN 59 chamfer as the standard construction for this design (Fig. 4.11). R tube A Fig 4.9 The method of separating the nut from the screw spindle Fig 4.1 Chamfer for seating the face of bearing end F.4X.2IN59 F.6X.3IN59 F1X.2IN59 Fig 4.11 Suggested chamfer dimension per IN 59 for the A dimension in Fig 4.1

Ordinary rolled ballscrews are used for application grade less accurate but still requiring high efficiency and long service life. Precision grade rolled ballscrews have an accuracy between that of the ordinary grade rolled ballscrews and the higher grade precision ground ballscrews. They can be used to replace certain precision ground ballscrews with the same grade in many applications. HIWIN makes precision grade rolled ballscrew up to C6 grade. eometric tolerances are different from those of precision ground screws (See Chapter 6). Since the outside diameter of the screw spindle is not ground, the set-up procedure for assembling precision rolled ballscrews into the machine is different from that of ground ones. Chapter 7 contains the entire description of rolled ballscrews. (1) Accuracy grade There are numerous applications for ballscrews from high precision grade ballscrews, used in precision measurement and aerospace equipment, to transport grade ballscrews used in packaging equipment. The quality and accuracy classifications are described as follows: lead deviation, surface roughness, geometrical tolerance, backlash, drag torque variation, heat generation and noise level.

17 S99TE HIWIN precision ground ballscrews are classified to 7 classes. In general, HIWIN precision grade ballscrews are defined by the so called V 3p value see Fig 4.12 and rolled grade ballscrews are defined differently as shown in Chapter 7. Fig is the lead measuring chart according to the accuracy grade of the ballscrews. The same chart by the IN system is illustrated in Fig From this diagram, the accuracy grade can be determined by selecting the suitable tolerance in Table 4.2. Fig shows HIWIN s measurement result according to the IN standard. Table 4.2 shows the accuracy grade of precision grade ballscrews in HIWIN s specification.the relative international standard is shown in Table 4.3. The positioning accuracy of machine tools is selected by e p value with the V 3p variation. The recommended accuracy grade for machine applications is shown in Table 4.5. This is the reference chart for selecting the suitable ballscrews in different application fields. (2) Axial play (Backlash) If zero axial play ballscrews (no backlash) are needed, preload should be added and the preload drag torque is specified for testing purpose. The standard axial play of HIWIN ballscrews is shown in Table 4.4.For CNC machine tools, lost motion can occur in zero-backlash ballscrews through incorrect stiffness. Please consult our engineers when determining stiffness and backlash requirements. (3) eometrical tolerance It is crucial to select the ballscrew of the correct grade to meet machinery requirements. Table 4.6 and Fig 4.15 are helpful for you to determine the tolerance factors, which are based on certain required accuracy grades.

23 S99TE Preload Methods The specially designed othic ball track can make the ball contact angle around 45. The axial force F a which comes from an outside drive force or inside preload force, causes two kinds of backlash. One is the normal backlash, S a caused by the manufacturing clearance between ball track and ball. The other is the deflection backlash, Δl caused by the normal force F n which is perpendicular to the contact point. The clearance backlash can be eliminated by the use of an preload F a (or P) S a 2 l 2 F n Fig 4.16 othic form profile and preloading relation internal force P. This preload can be obtained via a double nut, an offset pitch single nut, or by adjusting the ball size for preloaded single nuts. The deflection backlash is caused by the preload internal force and the external loading force and is related to that of the effect of lost motion. F n l 2 S a 2 F a (or P) F a (or P) Y axial load l S a l X deflection (1) ouble nut preloading Preload is obtained by inserting a spacer between the 2 nuts (Fig. 4.17). Tension Preloading Compression Preloading Tension preload is created by inserting Spacer an oversize spacer and effectively pushing the nuts apart. Compression pre-load is created by inserting an undersize spacer and correspondingly pulling nuts together. Tension preload is primarily used for precision ballscrews. Tension Load Spacer Tension Load Compression Load Compression Load However, compression preload type Fig 4.17 Preload by spacer ballscrews are also available upon your request. If pretension is necessary to increase stiffness, please contact us for the amount of pretension to be used in the ballscrew journal ends. (.2mm to.3mm per meter is recommended, but the T value should be selected according to the compensation purpose). (2) Single nut preloading There are two ways of preloading a single nut. One is called the oversizedball preloading method. The method Tension Load Tension Load Lead Lead is to insert balls slightly larger than the Lead Lead+δ Lead ball groove space (oversized balls) to allow balls to contact at four points (Fig. 4.18). Nut Nut The other way is called The offset pitch preloading method as shown in Screw Shaft Fig The nut is ground to have a Lead Screw Shaft Lead Lead δ value offset on the center pitch. This method is used to replace the traditional double nut preloading method and has Fig 4.18 Preload by ball size Fig 4.19 Offset type preloading the benefit of a compact single nut with high stiffness via small preload force. However, it should not be used in heavy duty preloading. The best preload force is below 5% of dynamic load (C).

It is measured by rotating the screw spindle at constant speed while restraining the nut with a special fixture as shown in Fig The load cell reading force Fp is used to calculate the preload drag torque of the ballscrew. HIWIN has developed a computerized drag torque measuring machine which can accurately monitor the drag torque during screw rotation. Therefore, the drag torque can be adjusted to meet customer requirements (Fig. 2.5). The measurement standard for preload drag torque is shown in Fig and Table 4.7. (2) Measuring conditions 1.

This will cause the ball screw to bend under the stress of vibration coupled with the centrifugal forces due to the rotation and cause the shaft to vibrate violently. Therefore, the rotational speed of the ball screw should be set to below the value indicated by critical speed.

For HIWIN ballscrew, m N 7, M33 m : Pitch circle diameter (mm) N : Maximum speed (rpm) Ballscrew structure enhancement designed by HIWIN when m-n value ranges from 7, to 18,. If m -N value above 18,, please consult our company. Stiffness Stiffness is an indication of the rigidity of a machine. The stiffness of the ballscrew is determined by nut-spindle rigidity via axial load, balltrack contact rigidity and screw spindle rigidity. When assembling the ballscrew in the machine, the stiffness of support bearing, mounting condition of nut with machine table etc. also should be considered. Fig 4.27 shows the relation of total stiffness of the machine feed system. From testing, the stiffness of nut-spindle relation and ball and balltrack relation can be combined into the stiffness of nut, Kn, and listed in dimension table of different nut type. The stiffness of the ballscrew is shown as : 1 K bs = 1 K s + 1 K n M34 K bs : Total stiffness of ballscrew (kgf/µm) The stiffness of the screw spindle is shown as : K s = 67.4 dr2 L 1 (Fixed-Fixed) K s = 16.8 dr2 L 1 (Fixed-Free) The stiffness chart is shown in Fig 4.28 d r : Root diameter of screw spindle (mm) b : iameter of ball (mm) K s : Screw spindle stiffness (kgf/µm) K n : Nut stiffness (kgf/µm) m b M35 M36 M37 The stiffness of the nut is tested using an axial force equal to the highest possible preload of 1% dynamic load (C) and is shown in the dimension table of each nut. When the preload is less than this value, the stiffness of the nut is calculated by extrapolation method as : K n =.8 K P.1C 1/3 M38 K n : Stiffness of nut K : Stiffness in the dimension table P : Preload C : ynamic load on dimension table Single nut with backlash is calculated when the external axial force is equal to.28 C, thus : K n =.8 K F b 2.8.1C 1/3 M39

HIWIN recommends a T value of -.2 ~ -.3 per meter for CNC machine tools. Basic dynamic axial load rating C (theoretical) The dynamic load is the load at which 9% of the ballscrews will achieve the service life of 1 x 1 6 rev (C). The reliability factor can be adjusted by Table 4.8. The dynamic load is shown on the dimension table of each nut type. Basic static axial load rating Co (theoretical) The static load is the load which will cause the balltrack to have a plastic deformation exceeding.1x ball diameter. To calculate the maximum static load of a ballscrew, the static safety factor S f of the application condition should be considered. S f F a (max) < Co S f : Static factor = 2.5 max Co : Static load from the dimension table of the nut type F a (max) : Maximum static axial load M41

Total stiffness K t =13.2 kgf/µm and total lost motion δ =.16 mm. The difference is only 6 µm (5% change). comparing with 25 kgf, preloaded nut, but the temperature rise caused by 5 kgf preload is heavy. The spindle stiffness is sometimes more important than the nut stiffness. The best way to increase the stiffness of the system is not in the heavy preloading of the ballscrew nut. If the support method changes to fixed-fixed, then K s =82 kgf/µm and K t becomes 23 kgf/µm. The total lost motion d =.61 mm. The difference is 51µm (45%).

37 Manufacturing range S99TE The maximum length to which a ballscrew can be manufactured depends on spindle diameter and accuracy grade (Table 4.1). Since high accuracy ballscrews require a high degree of straightness to the screw spindle, the higher the slender ratio (length/diameter), the more difficult to manufacture and the less the spindle stiffness. HIWIN recommends the maximum lengths shown in Table 4.1. If a longer length is required, please contact with HIWIN engineer. Table 4.1 eneral manufacturing range of HIWIN screw spindle vs. diameter and accuracy grade Unit : mm Total O.. length rade C C C C C C C C Please consult with HIWIN in this area Heat treatment HIWIN s homogenous heat treatment technique gives the ballscrew maximum life capability. Table 4.11 shows the hardness value of hardness in each component of HIWIN ballscrews. The surface hardness of the ballscrew affects both dynamic and static load value. The dynamic and static values shown in the dimension table are the values for a surface hardness equal to HRC 6. If the surface hardness is lower than this value, the following formula will give you the calibration result. C o = Co f HO f HO = Real Hardness (HRC) M42 C = C f H f H = Real Hardness (HRC) M43 Where f H and f HO are the hardness factor.

The following factors have the effect of raising the temperature in a ballscrew. (1) Preload (2) Lubrication (3) Pretension Fig 4.29 shows the relation of working speed, preload and temperature rise. Fig 4.3 shows the relation of nut temperature rise to preload friction torque.

However, to increase the rigidity of the ballscrew nut, it is necessary to preload the nut to a certain level. Preloading the nut will increase the friction torque of the screw, making it more sensitive to an increase in temperature during working period. HIWIN recommends using a preload of 8% of the dynamic load for medium and heavy preload, 6% ~ 8% for medium preload, 4% ~ 6% for light and medium and below 4% for light preload. The heaviest preload should not exceed 1% of the dynamic load for best service life and a low temperature rise effect. (2) Lubrication effect The selection of lubricant will directly influence the temperature rise of the ballscrew. HIWIN ballscrews require appropriate lubrication either by greasing or oiling. Antifriction bearing oil is recommended for ballscrew oil lubrication. Lithium soap based grease is recommended for ballscrew greasing. The basic oil viscosity requirement depends on the speed, working temperature and load condition of the application. (Fig 4.31) shows the relation of oil viscosity, working speed and rise in temperature. When the working speed is higher and the working load is lower, a low viscosity oil is better. When the working speed is lower and the working load is heavy, a high viscosity oil is preferred. enerally speaking, oil with a viscosity of 32 ~ 68 cst at 4 C (ISO V 32-68) is recommended for high speed lubrication (IN 51519) and viscosity above 9 cst at 4 C (ISO V 9) is recommended for low speed lubrication. In high speed and heavy load applications the use of a forced coolant is necessary to lessen the temperature. The forced lubrication of coolant can be done by a hollow ballscrew. Fig 4.32 shows the comparison of a ballscrew applied with coolant and without coolant. Fig 4.33 shows a typical application for hollow ballscrew in machine tools. The inspection and replenishing of the ballscrew lubricant is listed in Table 4.12.

39 (3) Pretension effect S99TE When the temperature rises in the ballscrew, the effect of thermal stress will elongate the screw spindle. It can make the spindle length unstable.ø The elongating relationship can be calculated according to M41. This elongation can be compensated via the pretension force. For the purpose of pretension, there is a negative T value indicated in the design drawing to compensate the pretension value. Since a large pretension force will cause the burn down of the supporting bearing, HIWIN recommends using pretension when the temperature rise is below 5 C. Also, if the diameter of the screw spindle is greater than 5 mm, it is not suitable for pretension. A large spindle diameter requires a high pretension force, causing burn down of the supporting bearing. HIWIN recommends a T compensation value of about 3, (about -.2~.3 for each 1 mm screw spindle). Since different applications require different T values, please contact HIWIN engineer.

140 136 S99TE Rolled Ballscrews 7.1 Introduction HIWIN Rolled Ballscrews are made by the rolling process of the screw spindle instead of the grinding process. Rolled ballscrews not only have the benefit of low friction and smooth running for the linear feed system compared with traditional screws, but also can be supplied by quick stock delivery and lower production price. HIWIN uses the most advanced technology in the ballscrew rolling process. By maintaining the homogeneous manufacturing procedure of selecting materials, rolling, heat treating, machining and assembling. In general, rolled ballscrews use the same preload method as the precision ground ballscrews, except that there are some differences in the lead error definition and the geometric tolerance. The grade of the rolled ballscrews can be ordered according to the same nut dimension of the precision ground ballscrew. If the ends of the spindle are unmachined, the geometric tolerance does not apply. The production scale of each type of the ballscrews and the accuracy classification are described in the following sections (the unit of length used is in mm). 7.2 Precision Rolled Ballscrews Table 7.1 gives the lead accuracy of the precision rolled ballscrews. The lead accuracy is measured by the accumulated lead error of any portion of 3 mm in length. The maximum axial plays of the precision rolled ballscrews are shown in Table 7.2. These ballscrews can be preloaded as the precision ground ones. The categories of the precision rolled ballscrews are listed in Table 7.3. Fig. 7.1 show the geometric tolerance of the general rolled ballscrews. has a variety of the precision rolled ballscrews for our customers urgent requirement.

Features: 1. Optimized design for high reliability: Use of computer simulation and FEM analysis, the cool type ballscrew features well thermal protection and high reliability. 2. Promote higher speed rotation and extra high m-n value (up to 2,): Cool type ballscrew will eliminate high-speed rotation aftereffect, i. e., thermal problem, and promote higher speed rotation. 3. Prevent thermal distortion: Optimized heat transfer design to minimize heat generation and prevent thermal distortion. 4. Strengthen durability: When operating repeatedly, friction between balls cause heat generation. That may be made balls oxidized or decarburized, and shortened the service life. Cool type ballscrew will strengthen durability under a cooling environment. 5. Extended lubricant life cycle: When using lubrication, minimum heat generation further inhibits deterioration in the quality of lubrication and extends the lubricant life cycle. 6. Keep temperature uniform and reduce warm-up time: When high-speed operation, nut and shaft cooling effect indeed keep feed-system temperature constant and reduce warm-up time. 7. Higher feeding accuracy: Cooling effect of cool type ballscrew will stabilize against thermal expansion and equalize feeding accuracy.
