Elastomer Jaw Couplings GWE 5102 | RINGFEDER®

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.

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 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.

Characteristics GWE 5102

  • Low mass through aluminium hubs
  • Optimisation of the vibration damping through different elastomer spider hardness levels
  • Standard with yellow elastomer spider (92 SH A)
  • Puncture-proof and electrically insulating
  • Length of threaded pin adapted to bore
  • Coupling hubs optionally with keyways in accordance with DIN 6885-1
