Ringspann SIKUMAT SB

The torque is transmitted via six pairs of rollers pressed by coil springs into detents. When the preset limit torque has been reached, the rollers move against the spring force up the sloping surface and disengage. This characteristic, combined with the particular geometry of the detents, provides a high degree of consistency to the limit torque of the SIKUMAT throughout the operating period. Re-engagement is effected synchronously after 360° due to the asymmetrical division of the detents

Advantages

• A high degree of consistency of limit torque throughout operation through the double roller principle

• Switching off in case of overload – separation of input and output

• Synchronous re-engagement after 360°

• Torques up to 10 000 Nm

• For shaft diameters up to 125 mm

Function

• When the preset limit torque has been reached, the SIKUMAT effects a separation of input and output using a locking mechanism with integral bearings.

• Following the elimination of the overload, manual synchronous re-engagement of the SIKUMAT to the starting position after 360°.

• This requires an axial switching force to be applied to the switching ring.
