Norman G. Clark, representing R+W, unveiled the ST model torque limiters.
Designed for high torque capacities that are achieved by strong modules evenly spread on the circumference, the ST model minimises machine downtimes due to crashes, according to the company.
The torque limiter model ST is based on a spring-loaded form-fit design; the transmittable torque is determined by the number of modules that are evenly spread on the circumference and their bolt circle diametres.
In the event of a torque overload, the balls jump out of the detents in axial direction resulting in a permanent separation of the drive and driven elements. An axial force on the plunger re-engages the module.
Dust and dirt penetration is prevented by the sealed torque limiter design.
