A shaft coupling is required to connect the threaded spindles to the motor shaft. The coupling must transmit the rotary movement and the torque of the motor to the spindle to be driven.

Depending on the offset to be compensated (axial, lateral or angular), rigid couplings, elastomer couplings (also known as claw couplings) or metal bellows couplings are available.

In order to synchronize two screw drives, it is possible to use intermediate shaft couplings.

The coupling is usually connected using a keyway connection. However, there are also variants with a clamping hub, with a conical clamping ring or with an expanding mandrel available on the market.

junaspin is happy to support you in the selection and design of your shaft coupling. We supply couplings from our partner StS Coupling GmbH from Niedernberg.
