Elastomer Jaw Couplings GWE 5102

Miniature coupling with set screw hubs

RINGFEDER^® GWE 5102 is a compact miniature coupling and the solution for low torque and narrow installation spaces. The coupling halves are ﬁxed to the shaft with threaded pins rather than with clamping hubs. The shaft tolerance should lie within the ﬁtting tolerance ‘g6’ to ‘h7’. Two threaded pins offset by 120° produce the contact pressure between the coupling hub and the shaft that is necessary to transmit the torque.

The elastomer spiders are available in different Shore hardness levels. Whichever version you choose: RINGFEDER^® GWE 5102 miniature is electrically insulating and vibration damping.

Pluggable
Vibration damping
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.
