SIKUMAT® SA … Synchronous Ratcheting with double rollers

The torque is transmitted via six pairs of rollers which are 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 provide a high
degree of consistency to the limit torque of the SIKUMAT® over the duration of the operating period. Re-engagement is effected synchronously after 360° due to the asymmetrical division of the detents

Advantages

• High degree of consistency of limit torque over the duration of operation through double roller principle
• 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® ratchets.
• Following elimination of overload automatic synchronous re-engagement of the SIKUMAT® to the starting position after 360°.
• The overload can be indicated by a proximity switch. This means that the drive can be switched off immediately or another control function can be activated.
