8 Lead-screw ssembies

9 Overview of Lead-screw ssembies Haydon Kerk Motion Soutions products have been designed specificay for motion contro appications. They are not compromised adaptations of genera purpose screws or nuts. The screw thread form is designed for maximum ife, quiet operation, and compatibiity with Haydon Kerk Motion Soutions anti-backash nut designs. LED-SREW TEHNOLOGIES KERK LED-SREWS are avaiabe in standard diameters from 5/64-in (2 mm) to 15/16-in (23 mm), with standard eads from.012-in to amost 4-in (0.30 mm to 92 mm) incuding hard metric and eft hand threads. ustom sizes and eads can be specia ordered. Most stock screws are manufactured from 303 stainess stee and are produced with Haydon Kerk Motion Soutions excusive precision roing process. Other materias are avaiabe on specia order. Positiona bi-directiona repeatabiity (with Kerk anti-backash nut) is within 50 micro-es (1.25 micron) and standard ead accuracy is better than in./in. (mm/ mm). Lead accuracies are avaiabe to.0001-in./in. (mm/mm). Haydon Kerk Motion Soutions tota in-house manufacturing and quaity contro assure uniform and consistent products. KERK NUTS are avaiabe in 8 standard anti-backash designs (MP, ZX, WDG, NT, KHD, VHD, NTG, Z); genera purpose FW Series pus the Mini Series. (See Product omparison hart for size avaiabiity). ustom nut configurations and mountings are aso readiy avaiabe. The Kerk brand anti-backash designs provide assembies which are wear compensating with ow frictiona drag and exceptiona positiona repeatabiity. Operation to more than 300 miion es of trave can be achieved. Haydon Kerk Motion Soutions provides nuts in a wide range of wear resistant, sef-ubricating thermopastic materias. 11

10 Lead-screw ssembies: nti-ackash Technoogies LED-SREW TEHNOLOGIES xia Take-up Mechanism The standard method for taking up backash is to bias two nut haves axiay using some type of compiant spring. (Wavy washer, compression spring, rubber washer, etc.) NUT HLF SPRING PRELOD NUT HLF The unit is very stiff in the direction in which the nut haf is oaded against the fank of the screw thread. However, in the direction away from the screw thread, the nut is ony as axiay stiff as the amount of preoad which the spring exerts. NUT HLF SPRING FORE LOD GINST SREW FLNK For exampe, if the maximum axia oad to which the system is subjected is 50 bs., the amount of spring preoad must be equa to, or greater than, 50 bs. in order to maintain intimate screw/nut contact. The probems arising from preoading in this manner are increased drag torque and nut wear. Obviousy, the higher the oad at the screw/nut interface, the higher the required torque to drive the nut on the screw and the more susceptibe the unit is to nut wear. n aternate method repaces the spring with a stiff spacer sized to fit exacty between the two nut haves. NUT HLF (L) STIFF SPER NUT HLF There is no excessive preoad force at the interface and the unit is capabe of carrying high axia oads in either direction with no backash. This is fine initiay. However, as use time increases, wear begins on the nut threads causing a gap to deveop between the spacer (L) and the nut haves. 1 2 NUT HLF (L) NUT HLF This gap ( 1 + 2) is now the amount of backash which has deveoped in the unit. This backash can be removed by repacing the stiff spacer with a new spacer equa to (L ). This process, athough effective, woud be extremey costy and difficut to impement on a continuous basis. The Soution What is needed, then, is a stiff spacer which wi continuay expand to accommodate the wear which occurs during use. This is done by creating a spacer threaded at one end with a compimentary nut torsionay biased to advance when a gap deveops. The thread at the end of the spacer is a fine heix such that an axia oad wi not backdrive the nut once spacer growth has occurred. L The preoad on the unit is ony the amount necessary to turn the spacer nut on the spacer rod and is independent of the externa system oadings. We thus have a sef-wear compensating unit which has extremey ow frictiona drag torque yet high axia stiffness. L

11 Lead-screw ssembies: Lubrication Kerkote and ack Ice TFE oatings Haydon Kerk Motion Soutions, Inc. offers mutipe options for ubrication. Kerk ead-screw nuts feature sef-ubricating poymers. When maximum performance is required, Kerkote and ack Ice TFE coatings provide unmatched resuts in the most demanding appications. LED-SREW TEHNOLOGIES The purpose of TFE coating is to suppy a more even distribution of ubricant than is normay found when using standard sef-ubricating pastics on stee. The wear ife, coefficient of friction and resuting torque to drive a ead-screw assemby are highy governed by the abiity of the engineered pastic to suppy sufficient ubrication to the nut/ screw interface. The inabiity of the interna ubricating agents in some pastics to consistenty migrate to the surface may resut in erratic drag torques and unpredictabe wear. Kerkote TFE oating Kerkote TFE coating covering the entire screw surface resuts in an extremey even ubrication distribution. Test resuts indicate system torque requirements are consistenty ow with itte or no change in required frictiona driving torque, even with changes in motor R.P.M. Haydon Kerk Motion Soutions has deveoped a custom composition Kerkote TFE specificay for our ead-screw and nut materias. It is appied using an automated process and provides extended nut ife and smooth operation with itte additiona cost. Kerkote TFE is a soft coating, a ong-term dry ubricant that is optimized for softer pastics ike acetas and nyons, with or without mechanica reinforcement. Lubrication to the nut/screw interface occurs by the nut picking up Kerkote TFE partices from the coating as we as from the migration of the interna ubricant within the pastic nut. though care is taken to ensure that chips and voids do not occur in the coating, sma voids have been shown to have no effect on system performance. The transfer of TFE to the nut continues throughout the operating ife of the assemby as ong as the nut periodicay traves over areas with Kerkote TFE coating. The ubricant, athough soid, aso has some spreading abiity as in fuid ubricants. Kerkote TFE coated screws provide the maximum eve of sef-ubrication and shoud not be additionay ubricated or used in environments where ois or other ubricant contamination is possibe. ack Ice TFE oating ack Ice TFE coating shares many of the benefits of Kerkote TFE but, in contrast, is a hard coating that offers exceptiona durabiity in a types of environments, with virtuay any type of poymer nut. ack Ice TFE coating remains on the screw, offering a ow friction surface upon which the nut traves. Rather than acting as a dry ubricant, ack Ice TFE is an anti-friction coating whose surface properties dispace the meta to which it is appied. Though it is not intended for use with meta or gass fiber reinforced nuts, ack Ice TFE is bonded securey to the screw s surface and can withstand abrasion from contamination, rigid poymer systems, fuid impingement and wash down appications. ack Ice TFE can be used in the presence of more aggressive environment conditions, or anywhere reduced friction and a permanent coating is desired. oth Kerkote and ack Ice TFE coatings offer the advantages of dry ubrication. These are maintenance-free coatings that are designed to ast the ife of the product. They are intended to be used without additiona ubricants, thereby further increasing the vaue of Kerk ead-screw assembies through eimination of the most common faiure of screw driven drives, ubrication faiure. There are certain appications where externa ubrication may be desired. These incude the use of nut materias such as gass reinforced pastic or meta. Greases, when used propery can provide unique capabiities and Haydon Kerk Motion Soutions does offer a seection of greases deveoped specificay for these appications. Pease contact a saes engineer for assistance seecting the best ubricant for your requirements. 13

12 Lead-screw ssembies: Materias LED-SREW TEHNOLOGIES 303 Stainess Stee Kerk brand ead-screws and inear rais start with premium grade 303 stainess stee. Haydon Kerk Motion Soutions, Inc. has identified the materia properties most critica for producing the very high quaity roed stee screws in the word and contros these to eves unmatched in the industry. ecause of our eadership position, we are abe to utiize this exceptiona quaity stee without having to charge premium prices. Kerk stainess stee ead-screws and guide rais are corrosion resistant, non-magnetic, and compatibe with many demanding processes. The idea starting point for a maintenance-free product, this premium quaity stainess stee is being used in numerous appications incuding medica appications, cean rooms, food and human contact, sat spray, cryogenics and vacuum. Kerkite omposite Poymers In addition to the Kerk sef-ubricating aceta nut materia, Haydon Kerk Motion Soutions offers a variety of custom compounded Kerkite composite poymers. Kerkite poymers are a famiy of high performance materias that offer exceptiona wear properties with the cost and design advantages afforded through injection moding. Kerkite poymers offer a variety of mechanica, therma and eectrica properties and are compatibe with many chemicas and environmenta conditions. Kerkite omposite Poymers are avaiabe options for most Kerk Lead-screw s and are standard materias for Linear Rai and Spine Shaft bushings, RGS arriages and Screwrai ushings and End Supports. Each member of the Kerkite famiy is compounded with ubricants, reinforcements and thermopastic poymers formuated to provide optimum performance in its target conditions and appications, resuting in superior performance and extended ife. cornerstone of the Haydon Kerk Motion Soutions advantage is design fexibiity. Kerkite omposite Poymers, aong with our injection moding and mod making capabiities, offer huge design advantages and cost savings compared with non-modabe materias. Kerkite high performance poymers outperform other pastics and outast meta bushings and bearings. When combined with Kerkote or ack Ice TFE coatings, Kerkite omposite Poymers have been shown to provide hundreds of miions of es of trave in customer appications whie continuing to maintain precise, accurate motion and positioning. Specia Materias In addition to the Kerk standard materia 303 stainess stee, sef ubricating aceta and Kerkite high performance composite poymers we aso work with a vast array of custom materias. Kerk has roed screws in many other materias, incuding 316 stainess, 400 series stainess, precipitate hardening materias, carbon stee, auminum, and titanium. Kerk nuts had been produced in many aternative pastics incuding PEEK, poyester, Toron, Vespe, PVDF, UHMW, Ertayte and customer-suppied speciaty materias. We have aso provided meta nuts made from bronze, brass, and stainess stee.

LED-SREW TEHNOLOGIES End Machining Haydon Kerk Motion Soutions can custom machine screws to your specifications or provide cut-to-ength screws for your own machining. ritica Speed This is the rotationa speed at which a screw may experience vibration or other dynamic probems. See RITIL SPEED HRT to determine if appication parameters resut in speed approaching critica. To minimize critica speed probems: use a onger ead, choose a arger diameter or increase bearing mount support. Lengths Lengths can be specified up to 12 ft. (4M) from stock, (depending on diameter and ead). ut to ength screws are offered in 6-in increments (6-in, 12, 18,...) +1.0-in/-0-in. Lead dvancement per revoution. screws are isted by ead, not pitch. Lead = Pitch x Number of Starts Pitch rest-to-crest distance or one divided by threads per. (On a mutipe start thread, the pitch equas the ead divided by the number of starts.) 15

14 Lead-screw ssembies: Design & Engineering Data LED-SREW TEHNOLOGIES Traverse Speed The nut materias we use provide ong wear-ife over a wide variety of conditions. However, very high oads and/or speeds wi acceerate nut wear. Specia materias may be required for these situations. We offer the foowing guideines for continuous duty inear traversing speeds for optimum ife: Lead Traverse Speed Lead Traverse Speed 1/10-1/2-in 4-in/sec. 1/2-1-in 10-in/sec /2-in 30-in/sec mm 100 mm/sec mm 250 mm/sec mm 760 mm/sec. Maximum though the Kerk nti-ackash ssembies are capabe of withstanding reativey high oads without catastrophic faiure, these units have been designed to operate under the oading shown in the size charts. Efficiency Efficiency is the reationship of work input to work output. It shoud not be confused with mechanica advantage. Listed efficiencies are theoretica vaues based on Kerkote TFE coated screws. Torque The required motor torque to drive a ead-screw assemby is the sum of three components: the inertia torque, drag torque, and torque-to-move oad. It must be noted that this is the torque necessary to drive the ead-screw assemby aone. dditiona torque associated with driving frictiona bearings and motor shafts, moving components, and drag due to genera assemby misaignment must aso be considered. Inertia Torque: T j = I α Where I = screw inertia α = anguar acceeration Drag Torque: The Kerk nti-ackash ssembies are typicay suppied with drag torque of 1 to 7 oz.-in. The magnitude of the drag torque is dependent on the standard factory settings or settings specified by the customer. Generay, the higher the preset force, the better the nti-ackash characteristics. Torque-to-Move: T L = LOD x LED 2p x EFFIIENY ack Driving Sometimes referred to as reversibiity, back driving is the abiity of a screw to be turned by a thrust oad appied to the nut. Generay, back driving wi not occur when the screw ead is ess than 1/3 the diameter for uncoated screws or 1/4 the diameter for Kerkote TFE coated screws. For higher eads where back driving is ikey, the torque required for hoding a oad is: LOD x LED x KDRIVE EFFIIENY T = b 2p Screw Straightness Screw straightness is measured as Tota Indicator Runout(TIR). The standard straightness for ead-screws is.003-in/ft. Haydon Kerk Motion Soutions can provide tighter specifications on customer request. screws are hand straightened before shipping. 16
