Torque limiter free rotation DSS/SG/RF
A backlash free Safety coupling with free rotation and low residual torque suitable for high speed transmission. The disengagement is instantaneous once the torque is reached, the calibration is adjusted by changing the pressure of the springs. The re-engagement is manual, quick and reliable.
- Absence of torsional play during the transmission of motion;
- Fine-tuning the torque through a balanced radial ring;
- Motion transmission through balls;
- An innovative calibration system with “H fee” for an immediate calibration of the equipment;
- Manual re-engagement with one coupling position per lap;
- No residual torque after disengagement;
- Possibility of combining a switch/proximity to stop the engine.
- Complete transmission gear worked and fitted (crown, pulley, gear, …);
- Can be supplied with various type of rigid/elastic couplings for in-line shafts transmission;
- Possibility of surface treatments for corrosion-specific needs;
- Possibility to have the version with the attacks of the 8-hole competition.
- Extruders;
- Packing machines;
- Automation technology;
- Test benches.
- Protect the elements of a transmission even in case of high inertias;
- Protect the product from shock or incorrect positioning;
- Protect mechanic devices during transmission at high speeds of rotation;
- Greater durability of all devices, thanks to the free rotation.
