Applications of torque limiters can be found in all sectors of technique, in each and every machine or facility where torques have to be limited to protect machines or products from overload. The torque limiter type ECA, which is especially engineered for belt drives prevents such overload damages or at least reduces them to a minimum.
Particular worth was put on compulsion-cutting and fast switching function. Simple, light elements avoid adverse dullness of mass or switching. They were chosen because to heavy switching elements could considerable increase the (static adjusted) disengagement torque in case of a dynamic collision and therefore also the destructive collision forces.
In contrary to conventional friction clutches the ECA has a very high repeatability of the adjusted disengagement torque. It’s free of clearance and self-reliantly re-engages after 1 turn. The movement of switching can be sampled by a proximity switch. 17 design sizes make a total torque range of 0.5 Nm up to 470 Nm overall.
The ECA forms a very compact unit together with a crown gear, which hardly uses some additional place, and its deliverable in diverse versions (with keyway or conical bush).
