ROTEX® GS is a three-part coupling, backlash-free under pre-stress. The different hub designs and the different Shore hardnesses offer the optimal coupling for each application in automation engineering. In spite of its vibration-damping characteristics it is torsionally stiff so that it is not necessary to make any concessions to accuracy even with highly dynamic servo drives. The ROTEX GS works with the modular system; a high variety of different hub designs is available which can be combined within one coupling size.

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.
