Heavy-duty couplings offer reliable overload protection

Depending on the model size, up to twelve standardized switching units are located on the outer ring of the coupling, ensuring a backlash-free connection and reliable torque transmission.

This allows a high level of flexibility in terms of disengagement torque as well as coupling size and design. The working principle of the GWS series is based on a spring-loaded ball-in-detent arrangement. When the coupling is engaged, the steel balls located within the switching units are forced into a conical detent by spring pressure.

In the event of an overload condition, the disengagement torque preset on the switching units is exceeded, the steel balls move out of their detent in the axial direction, causing a stable separation of input and output sides, and thereby interrupting the torque transmission.

With a few steps and without having to dismount it, the overload coupling can be returned to operating mode so that the corresponding device or machine will be up and running as quickly as possible.

Ringfeder offers three models: in addition to a product with flange-hub and keyway-hub (GWS 5420), the portfolio includes a flexible coupling (GWS 5421) and a rigid disc coupling (GWS 5422), both with keyway-hubs on the input and the output side.

Optionally, GWS series couplings can be equipped with a switching disc and a mechanical limit switch on the motor side that can be used to disconnect the drive and send an alarm signal.
