Product features

  • Integrated clamping system from steel

  • Easy assembly due to internal clamping screws and block assembly

  • High friction torques, high smoothness of running

  • Application up to a peripheral speed of 40 m/s

This hub is specifically suitable for high shock loads. In high-torque drives these clamping ring hubs from steel are combined with hard spiders. It is provided with an internal clamping system, just like the ROTEX® GS clamping ring hubs light. The ROTEX® GS clamping ring hubs made of steel transmit high friction torques to smooth shafts. Moreover, they are suitable for high speeds subject to their symmetrical arrangement.

Performance

Apart from the jaw-type geometry of the coupling hubs the zero backlash of the ROTEX® GS is mainly due to the geometry of the ROTEX® GS spiders. These are designed in a way that the convex teeth of the spider contact the concave jaws of the coupling hub under prestress. In combination with the straight toothing this results in a small surface pressure and an increased stiffness of the coupling system. 

Spiders

The flexible spiders for the GS series are available in five different kinds of Shore hardness. The different kinds of Shore hardness allow to adjust ROTEX® GS easily to the individual conditions of an application with regard to torsional stiffness and vibration characteristics.

The flexible teeth are radially supported by a web on the inside diameter. In this way deformation caused by heavy acceleration or high speeds is prevented.

The permissible ambient temperature of the coupling depends on the Shore hardness of the spider.

This type is certified and confirmed according to directive 2014/34/EU as unit of category 2G/2D and thus suitable for the use in hazardous areas of zone 1, 2, 21 and 22. 

Please read through our information included in the respective Type Examination Certificate and the operating and mounting instructions.

Addition: If clamping ring hubs (clamping hubs without keyway are only permitted for category 3) are used in hazardous areas the coupling must be designed in a way that between the peak torque including all operating parameters and the torque of frictional engagement and the nominal torque of the coupling, resp., there is a safety of at least s=2.
