Ringfeder GWE 5103 Elastomer Jaw Coupling

Self-aligning coupling with clamping hubs, short length and single slit

The RINGFEDER® GWE 5103 series of backlash-free jaw couplings is characterised among other things by its compact design with low moment of inertia. It comprises two single-slit 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 ?tting tolerance ‘g6’ to ‘h7’.

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

Characteristics

Backlash-free Elastomer Jaw Couplings
RINGFEDER® GWE

Backlash-free RINGFEDER® GWE jaw couplings are used in engineering where high positioning precision requires vibration damping in greatly accelerated processes and the use of plug-in coupling solutions is preferred.

Advantages
Backlash-free, through pre-stressing 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 ?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.
