ROTEX® GS HP backlash-free high-speed coupling

Backlash-free servo coupling (high-speed coupling) for very high speeds

ROTEX® GS HP (high-performance coupling) is a three-part, backlash-free high-speed coupling.
It was developed to the highest standard for applications with high speeds.

Due to its closed design the high-speed coupling generates a minimum of air turbulence resulting in low noise even with exteme load. The ROTEX GS HP (high-performance coupling) is available in different hub types for various mounting conditions.

The ability for axial plug-in combined with various hub geometries results in a compact coupling system easy to assemble with high torque density.

Applications or our high-speed coupling ROTEX GS HP (high-performance coupling):

The ROTEX GS HP is used wherever extremely high speeds are generated, e. g. on main spindle drives and test benches.

New high-performance spider for backlash-free servo coupling

KTR has a new spider in its product range which decisively increases the performance level of the backlash-free servo couplings type ROTEX GS with regard to temperature resistance and pressure resistance. The material is a newly developed "thermoplastic polyurethane" with a hardness degree of "52 Shore D" and a temperature resistance of up to 120° C. The main areas of application are servo-hydraulics and test bench technology.

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.
