SIKUMAT® SC …Ratcheting with screw faces

Torque transmission is effected through screwshaped radial serrations in the input and output part, which are pressed together by spring force. Like the thread sides of a screw have edge contact with the nut during turning, so the toothed flanks of the SIKUMAT® retain their surface contact even during the torque disengaging process. This characteristic gives the SIKUMAT® an extremely high resistance against wear and therefore a long operating life.

Advantages

• Excellent robustness through surface contact during the disengaging process – therefore maximum life
• Fully enclosed with integral bearing – therefore maintenance-free
• Adjustment of limit torque setting according to the number of active springs – not through modification of spring pressure

Function

• When the preset limit torque has been reached the SIKUMAT® ratchets.
• After elimination of the overload the SIKUMAT® re-engages automatically.
• The overload can be indicated by the special proximity switch for the ratcheting SIKUMAT® with screw faces, thus either causing the drive to be switched off instantly or another control function to be activated.
