RADEX®-N - servo multiple disc clutch

Steel multiple-disc clutch – developed specially for servo technology

The backlash-free and torsionally rigid multiple disc coupling has been specially designed for the field of servo technology. Thanks to the discs of rust-free spring steel, it is extremely torsionally rigid and flexible at the same time. Aluminium hubs provide for a low moment of inertia. In the double-cardan version it even reliably compensates for radial shaft misalignments with low restoring forces.

The RADEX® NC is available in a single- and a double-cardan version - for high power ranges, the RADEX-NC is available in a High Torque (HT) variant.

Highlights

• Backlash-free torque transmission
• Increased torsional rigidity
• Low moment of inertia and high speeds

Structure and function

The connections between discs and hubs are designed in a force-fit and form-fit fashion. Their torsionally rigid and flexible discs are made of rust-free steel, the hubs of high-strength aluminium. The coupling is light, compact, and achieves a low moment of inertia. It is available in single- and double-cardan designs.

The backlash-free shaft-hub joint can be implemented in two ways:

for one, by using a clamping ring hub for the friction-type connection. The hub structure is rotationally symmetrically and suitable for high speeds. It is mounted on a block, which facilitates the installation of the coupling. The second way of implementing the connection is to use a clamping hub, optionally with a form-fit or force-fit connection.

The servo coupling is maintenance-free and can be used at temperatures up to +200° C and under aggressive ambient conditions.
