Elastomer Jaw Couplings GWE Z5106.1

Self-aligning coupling with clamping hubs in split hub design for large shaft spacings

As for the GWE Z5104.1 this balancing coupling RINGFEDER^® GWE Z5106.1 is also used to bridge large shaft separations. The clamping hubs in a half shell structure mean that the known beneﬁts are supplemented by the advantage of single radial assembly on the previously aligned shafts. It comprises two RINGFEDER^® GWE 5106, connected by an aluminium precision intermediate pipe. The shaft tolerance should lie within the ﬁt tolerance of ‘g6’ to ‘h7’.

Precision drives
Feed drives
Grinding and milling spindles
Machine tools
Packing machines
Robotics
Transfer lines
Multi-spindle heads
Wood processing equipment
Textile machinery
Conveying equipment

Linear motion
Measuring equipment and control technology
Test rigs

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 ﬁlling 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.
