ROTEX® GS P ETP

35 - 560 Nm / backlash-free servo coupling

The ROTEX GS P ETP hub with an integrated high-precision hydraulic clamping bush is particularly designed for quick and frequent assembly.

The hub of our servo laminae coupling (elastomer coupling) is made of steel and fastened to the shaft safely and frictionally engaged via one single screw. There is high concentricity even after frequent assembly/disassembly. This ensures smooth running even with high speeds. Assembly without axial shifting of hubs.

Features

backlash-free shaft coupling damping vibrations with integrated ETP quick clamping system
quick assembly / disassembly since one screw only needs to be tightened
severely good concentric running properties even after repeated assembly operations
assembly / disassembly for thousands of times
assembly in spaces difficult to access possible, since the pressure screw is tightened in axial direction to the shaft

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. This makes 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.
