Self-aligning coupling with clamping hubs for large shaft spacings
The backlash-free jaw coupling of the RINGFEDER® GWE Z5104.1 series that is designed as a torsionally ?exible intermediate shaft is used where torque or rotation need to be transmitted with the greatest possible angle precision and a large shaft separation needs to be bridged. It comprises two RINGFEDER® GWE 5104, connected by a precision hollow shaft in steel. The shaft tolerance should lie within the ?t tolerance of ‘g6’ to ‘h7’.

Technical description
Every hub on the RINGFEDER® GWE jaw coupling has concave jaws on its face. The function of the coupling to transmit torque and damp impact that occurs, as well as balancing out unavoidable mis- alignments, is enabled through the joining of two hubs and the ?lling of the created free space with an elastic sprocket. The GWE jaw couplings are backlash-free in order to also achieve a high level of positioning precision in reverse operation. The coupling is backlash-free as a result of the pressure pre-tensioning of the individual buffers in the elastomer sprocket. The different Shore hardness levels, which correlate to the torsional stiffness, mean that it is possible to optimise the entire drive line from the point of view of rotary oscillation. Detailed information is included in the technical data for the sprockets.
