3 Series Overview 1 ELM Series The ELM series is comprised of variously-sized linear units so that the designer and/or user is able to select the most suitable system according to loads and shuttling speed required. The ELM series actuators are constructed of self-supporting, extruded aluminum and incorporate a linear motion system. This system incorporates a maintenance free ball bearing guide, which is nested inside the extruded profile. The ELM series actuators use a steel reinforced polyurethane drive belt with AT pitch and parabolic profiles. All internal mechanical parts are protected against dust and foreign contaminants by a polyurethane sealing strip.

4 2 The Components Extruded Profile The anodized aluminium extrusion used for the body of the ELM series actuators were designed and manufactured in cooperation with a leading company in this field to obtain the right combination of high mechanical strength and reduced weight. Aluminium alloy 6060 was used (see physical and chemical characteristics on page 19). The dimensional tolerances comply with UNI 3879 standards. T-slots are provided for fast, hassle-free mounting. Carriage The carriage of the ELM series is made entirely of anodized aluminium. The dimensions vary depending on the size of the actuator. It consists of three parts to allow a sealing strip to pass through. For added protection, it is also fitted with specific seals (brushes) inserted in the front and sides. Each carriage has threaded holes fitted with stainless steel threaded inserts. Driving Belt The ELM series actuators use steel reinforced polyurethane drive belts with, AT pitch and parabolic profiles. This type of belt is ideal because of its high load transmission characteristics, compact size and low noise. Used in conjunction with a backlash-free pulley, smooth alternating motion can be achieved. Optimization of the maximum belt width-to-body dimension ratio enables the following performance characteristics to be achieved: High speed Low noise Low wear Sealing Strip ELM series actuators are equipped with a polyurethane sealing strip to protect all the internal components against dust and foreign matter. The sealing strip runs the length of the body and is kept in position by means of micro-bearings located inside the carriage. This ensures very low frictional resistance as the carriage travels through the strip.

5 The Linear Motion System 3 The linear motion system has been designed to meet high load, speed, and maximum acceleration conditions. The following linear motion system is offered: ELM SP with ball bearing guides The linear ball bearing guide with high load and moment capacities is mounted on the ball bearing seat inside the base of the extrusion. The carriage is assembled on two preloaded ball bearing blocks. The four-ball row configuration enables the carriage to withstand loading evenly in the radial (normal) and lateral (transverse) directions. The two blocks have seals on both ends and, when necessary, an additional scraper can be fitted for very dusty conditions. The ball bearing carriages of the SP versions are also fitted with a retention cage that eliminates steel-steel contact between adjacent rotating elements and prevents misalignment of these in the circuits. Lubrication reservoirs (pockets) installed on the front of the ball bearing blocks supply the right amount of lubricant, thus promoting maintenance-free operation. The linear motion system offers: High speed and acceleration High load capacity High bending permissible moments Low friction Long life Maintenance-free operation Low noise

7 Main Technical Characteristics 5 The sectioned drawings on the previous page showing the main characteristics help guide the process of an initial actuator size selection. For a final selection, refer to the data and dimensions in the pages listed at the end of each table. Type Max. Permissible Load radial (F z ) stat [N] side (F y ) load * 1 dyn [N] Max. permissible axial load (F x ) dyn [N] Max. speed [m/s] Max. acceleration [m/s 2 ] Max. positioning repeatibility [mm] See page ELM 50 SP ELM 65 SP ELM 80 SP ELM 110 SP *1 Reasonable operating life and system rigidity can be obtained from the values given. These values do not relate to the theoretical maximum permitted load capacity of the linear motion system. The load capacity of the ELM series depends on the linear motion system used and may vary according to the loading direction: radial (Fz) or lateral (Fy). The maximum load in an axial direction depends on the type of driving belt used. The maximum recommended values for the radial load (Fz) and the lateral load (Fy) indicated above incorporate a substantial factor of safety to ensure long lifecycles. Experience shows that these values ensure safe static and dynamic loading and adequate life for most applications. For special conditions (such as high shocks, vibrations, dusty environments, acceleration forces and high bending moments, etc), contact Rollon for further technical advice. Maximum permissible values for speed, acceleration and positioning repeatability may be decreased in the presence of high loads. Fz (radial) Fx (axial) Fy (lateral)

12 10 Planetary Gearbox The ELM units can be fitted with several different drive systems. In each case, the driving pulley is attached to the reduction gear shaft by means of a tapered coupling to ensure high accuracy over a long period of time. Versions With Planetary Gearbox Planetary gears are used for highly dynamic robot, automation and handling applications involving stressing cycles and are capable of high level precision requirements. Standard models are available with backlash from 3 to 15 and with a reduction ratio from 3:1 to 700:1. For assembly of a nonstandard planetary gear, contact Rollon.

17 Assembly and Accessories 15 The linear guidance systems used for the ELM series allow the actuators to support loads in any direction. The units can therefore be installed in any position. To install the units, we recommend the use of the T-slots in the extruded profile as shown below: Mounting by fixing brackets Unit: mm ELM 50 ELM 65 ELM 80 ELM 110 A Warning: do not fix the linear units through the heads at profile ends!

19 Lubrication 17 Lubrication Guidelines The ELM series of linear actuators use maintenance free linear ball guides. On the front plates of the linear blocks, special lubrication reservoirs are mounted which are continuously providing the necessary quantity of lubricant to the ball raceways under load. This system guarantees a service life of 20,000 km without relubrication. If a longer service life is required or in case of high dynamic or high loading applications, contact Rollon for further verification. The lubrication reservoirs fitted on the cages considerably reduce the frequency of lubrication of the module.

20 18 Protection Standard Protection Sealing Strip The ELM series is equipped with a polyurethane sealing strip to protect all parts inside the body against dust and foreign matter. The sealing strip runs the length of the body and is kept in position by micro-bearings located within the carriage. This ensures very low frictional resistance as it passes through the carriage. For further information about the sealing strip see page 19. Special Protection To use these linear units in very critical environments, they can be fitted with a bellows system in addition to the standard protection. The bellows is fixed to the carriage and the ends of the body by means of Velcro tape for easy assembly and disassembly. The total length (L) of the linear unit will vary. Add twice the length of the closed bellows package (2 x PCH). Protection of Ball Bearing Guides The ball bearing blocks have seals on both ends and, when necessary, an additional scraper can be fitted for very dusty conditions. Dimensions A B C D E F T for P A = 1000 ELM ELM ELM ELM P CH = Closed package length P A = Open package length T = fold depth Standard material: Thermally welded nylon coated with polyurethane. Materials on demand: Nylon coated with PVC, fiberglass, or stainless steel. Warning: The use of a bellows system does not allow the assembly of the proximity switch holders to the aluminium body!

22 20 Multi-Axis System Previously, customers wishing to build multi-axis units have had to design, draw and manufacture all the elements necessary to assemble two or more axes. Rollon now offers the accessory mounting brackets and hardware necessary to configure the multi-axis units. The ELM actuator units can also be easily connected to the ROBOT series actuators. In addition to the standard elements, Rollon can supply mounting plates and connectors for special applications.
