System Composition System Composition The HepcoMotion PRT2 system comprises of a comprehensive range of ring slides, ring segments, bearings and ancillary components which provide a versatile solution for most rotary and track system applications. A large range of ring slide types in various diameters are available in both steel and stainless steel with hardened V edges. Stock 90° and 180° segments are also available. Gear cut versions are available with pinions to provide a simple and effective means of driving. An overview of the comprehensive product range is shown 2 - 7. Single Edge...

System Composition System Composition HepcoMotion bearings are available in a range of 5 useful sizes and various formats to suit most design requirements. The special raceway conformity and low radial clearance make these bearings particularly suited to ring slide applications. All bearings are lubricated for life internally and are available with metal shields for exclusion of particulates and low friction running or, with nitrile seals to inhibit ingress of liquids. Bearings are also available in stainless steel fitted with nitrile seals. Ring Disc • • • • • • • Through hole fixing...

System Composition System Composition HepcoMotion track systems combine ring segments with straight slides to achieve an almost limitless variation of open paths or closed circuits. Both left and right hand bends can be negotiated depending on the carriage selected. 90° and 180° segments in all standard double edge ring sizes are available in addition to straight slides up to 4 metres long. Straight slides can be butted together to achieve track systems of unlimited length. Driven track system components • • • • Comprehensive range of drive components available from complete proven system....

Application Examples Application Examples Three Axis Assembly Robot HepcoMotion ring disc with gear drive provides an ideal platform on which to mount the robot. The large diameter disc with HepcoMotion bearings gives support at the periphery, ensuring excellent stability and friction free motion. 2 Rotary Assembly fixture HepcoMotion ring disc provides a large mounting area for attaching components. The precision ground surface ensures accuracy and the unhardened area inboard of the V's enables tooling holes to be drilled as required. Spray System Spray head mounted on HepcoMotion double...

Application Examples Application Examples Body Scanner Imaging head mounted on HepcoMotion ring slides rotate around the patient. Smooth, silent operation and zero play ensures high quality definition. HepcoMotion floating bearings cater for any slight differences in parallelism of the rings due to mounting and ensure that accuracy is determined by the master ring alone. Flash Removal from Moulding Carriage on track system accurately follows the profile of the product. Ridigity of the carriage assembly ensures a good quality finish of the trimmed edge. Multi-Station Assembly Machine...

Application Examples Carton Forming & Filling Line HepcoMotion Track system provides a simple means of transportation from station to station. Alternate carriages are independently driven enabling quick change over to different sizes by advancing one chain wheel in relation to the other. The zero play feature of the Hepco system ensures that the cartons are rigidly supported during the erecting, filling and closing operations. Figure of 8 Circuit for Test and Assembly HepcoMotion track system enables hydraulic manifolds to be friction driven to a test station and then to subsequent assembly...

Application Examples Application Examples Clamping Method for Belt to Carriage Connection Spider Drive Carriages are connected to the belt by means of clamping device , resulting in a strong fixing which overcomes the need to screw through the belt. The pulleys must be machined to provide recesses in order to accommodate the clamps. The slip block method 19 should be used to adjust track system length in relation to the tensioned belt. For short track systems carriages can be driven from a central motor and spider. The arms of the spider incorporate slots to accommodate the changing...

Application Examples Slotted Carriage Connection For Belt Adjustment The timing belt is fitted with U section attachments secured to the belt with countersunk screws. Pins engage with slotted drive member which drives the carriage around the circuit. In this type of design whether using a belt or chain, it is important to provide a slot to allow for tension adjustment and also to cater for slight variation in the proximity of carriage to belt or chain, as the carriage traverses from straight to curve. Application Examples Linked Carriage System With Scroll Drive Bogie carriages linked by...

Application Examples Application Examples Chain Tensioning for Long Track Systems Gear Driven Duplex Track System A track system driven by a chain or belt ideally requires a means of adjustment for pretensioning and to allow for subsequent wear and stretch, particularly in the case of a chain drive. Limited adjustment can be achieved by providing a slot at the chain to carriage connection point (see top illustration 16) or by link connection of chain to carriage (see centre illustration 16 and example below). However, in systems where a large amount of adjustment is anticipated or where the...
