Backlash free torque limiter DSS/SG
A ball safety coupling with high technology and precision. Provides backlash free transmission of motion with high sensitivity of reaction and an immediate release without peak load prior to release. The device can be adjusted by changing the pressure of the springs in the negative.
- Exact torque regulation through a balanced radial nut;
- Innovative calibration system by quote “H“ for an immediate calibration of the device;
- Re-engagement in equidistant phase (DSS/SG) or 360° (DSS/F/SG);
- Maintenance free;
- Possibility to add a microswitch / proximity to stop the motor drive;
- Model available only with finished bore;
- Drive component assembled and directly supported by a ball bearing.
- Complete with transmission component worked and assembled (plate wheel, pulley, gear,…);
- Available in stainless steel for food and pharmaceutical environments;
- Possibility to have a connection flange to the most common intermittent drive units;
- Feasibility in personalized phase at 30°, 45°, 60°, 90°, …
- Print machines and packaging machines;
- CNC tool machines;
- Index tables, filling machines, guiders;
- Servomotors, slide guides.
- To protect the product against faulty positioning on the rotating table;
- To protect the indexing against overloading along the transmission;
- To protect the operating units of machine tools against impacts;
- To protect slides or servomotors against impact or limit stops.
