Compact elastomer coupling

The backlash-free servo coupling (elastomer coupling) ROTEX GS Compact is characterized by its short design. The low-priced clamping hubs are made of aluminium allowing for easy and quick assembly of our backlash-free coupling.

The range of ROTEX GS Compact (backlash-free servo coupling) includes both frictionally engaged connections without feather keyway and positive-locking connections with feather keyway.

Features

backlash-free, torsionally flexible elastomer coupling / servo couplings
it is up to 1/3 shorter than standard types
axial slot, DBGM (German utility model)
good concentric running properties
uniform power transmission by cams without slots

Description of ROTEX GS servo couplings:

Our ROTEX GS 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 simultaneous 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 condition of ROTEX GS servo coupling:

Apart from the jaw geometry of the coupling hubs, zero backlash of the ROTEX® GS backlash free servo couplings (elastomer couplings) is largely based on the geometry of the ROTEX® GS spiders. They are designed in that the convex teeth of the spider fit the concave jaws of the coupling hub under prestress. Combined with the straight spline there is low surface pressure and higher stiffness of the coupling system.

Spiders of ROTEX GS servo coupling:

The flexible spiders of our servo couplings are available in five different kinds of Shore hardness. This allows to easily adapt the coupling to the individual conditions of an application considering the torsion stiffness and vibration characteristics.

The teeth of the spider absorb the displacements und are radially supported in the internal diameter by a web. With strong accelerations or high speeds this prevents too high internal or external deformation. The permissible ambient temperature depends on the spider's Shore hardness.
