The coupling parts can be arranged as required on the shaft ends to be connected. The coupling can be axially plugged in. Application Overview The damping properties of the couplings can be varied by the use of elastomer coupling elements of various degrees of hardness. BIPEX-S couplings are suitable for all drive applications which require a coupling that offers positioning accuracy and vibration damping. BIPEX-S couplings are positive-locking and torsionally flexible thanks to the polyurethane cam ring. Misalignment between the connected shafts deforms the coupling element/cam ring. The coupling element is pre-tensioned and is therefore assembled without backlash. The lobes attached to the element allow the coupling to compensate shaft misalignment, and also provide electrical isolation since they prevent contact between the two hub parts. BIPEX-S couplings are torsionally flexible and are free of backlash in the pre-tensioned state. They are characterized by their compact design and high power density. BIPEX-S couplings connect machine shafts and compensate for shaft misalignment that can occur during assembly or operation. The couplings can be axially plugged in during assembly. The hubs can be coupled to the shafts by many different methods including set screws, key joint, slotted clamping hubs, half-shell hubs, clamping hubs or expanding hubs. Benefits BIPEX-S couplings are fail-safe. When the coupling element is worn, the claws of the coupling hubs provide for fail-safe operation. Available in 4 different Shore hardness grades, the coupling elements allow to select the optimum degree of rigidity for any application. BIPEX-S couplings are ideal for use in servo drives, linear axes or rotary encoders of the type typically deployed in machine tools, packaging machines or printing presses. BIPEX-S couplings each comprise two hub parts connected by a coupling element or ‘cam ring’made of polyurethane (PU). BIPEX-S couplings within the standard catalogue range are available in 10 sizes with torque ratings ranging from 0.5 to 655 Nm. The coupling is suitable for ambient temperatures of between -30 °C and +90 °C. Coupling elements with alternative hardness grades can be supplied for ambient temperatures down to -50 °C or up to +120 °C. Design
