ROTEX® GS P acc. to DIN 69002 backlash-free servo couplings

Servo coupling with high precision and standardised stub spindles

The backlash-free servo coupling (elastomer coupling) ROTEX GS P clamping ring hub is a two-part taper hub made of steel with an integrated clamping system.

This servo coupling is characterised by high-precision machining and resulting good concentric properties and smooth running with high speeds.

Application ranges of our backlash-free servo coupling ROTEX GS P:
Applied in standardised stub spindles on multiple spindle heads acc. to DIN 69002

Servo coupling general description:

Our servo couplings are torsionally stiff shaft couplings soft in bending serving as a connection element between drive unit and measuring sensor. They transmit the torque free from backlash and conformally, making our backlash-free shaft couplings highly accurate. They also allow for compensation of radial, axial and angular displacements. Thanks to the high variety of coupling types and hub designs we are able to supply the right coupling for almost every application.

Backlash-free properties of servo couplings:

Apart from the jaw geometry of the coupling hubs, the backlash-free properties of the ROTEX® GS backlash-free servo couplings (elastomer couplings) are mainly based on the geometry of the ROTEX® GS spiders. They are designed in that they fit the concave jaws of the coupling hub with the convex teeth of the spider. Combined with the straight spline this results in lower surface pressure and higher stiffness of the coupling system.

Flexible spiders of servo couplings:

The flexible spiders of our elastomer couplings are available in five different kinds of Shore hardness. This allows to easily adjust the coupling to the individual specifications of an application in terms of torsional stiffness and vibration characteristics. The teeth of the spider compensating for displacements are radially supported in the internal diameter by a web. In this way excessive internal or external deformation with strong acceleration or high speeds are prevented. The permissible ambient temperature depends on the Shore hardness of the spider.
