Elastomer Jaw Couplings GWE 5103.1

Miniature coupling with extended clamping hubs and single slit

The RINGFEDER^® GWE 5103.1 series of backlash-free jaw couplings excel with their compact design. It comprises two single- slit long coupling hubs with high concentricity and one elastomer spider that can be supplied in different Shore hardness levels. The shaft tolerance should lie within the ﬁt tolerance ‘g6’ to ‘h7’.

The elastomer spider produces a backlash-free, puncture-proof, damped and electrically insulated elastic jaw coupling.

Torques from 0,5 – 650 Nm
Compensation of radial, axial and angular misalignment
Electrically isolating

Applications

Encoder
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.
