Stainless steel torque limiter

For limiting torques in indirect drives of bottling and cleaning plants, packaging machines, etc. Enemac supplies a special stainless steel version. The type ECR complies with the strict hygienic requirements in food-processing, pharma and medicine industry.

The type ECR is being developed out of approved type series and is composed completely of stainless steel; there are no coated parts involved in this coupling.

The used spring disc with decreasing force progression and relatively big pass was specially designed for this type of torque limiter. It ensures on-the-spot disengaging on the adjusted torque and enables big torque ranges without changing disc springs. Consequently, there is just little remaining force on the disc spring when the coupling disengages, leading to an importantly less wear behavior and thus extended product longevity.

The well-engineered ball-locking principal disconnects safely within a few angular degrees the engine from the machine. Through scanning the pass of the switch wafer with an inductive proximity switch it is possible to have an automatic emergency stop.

The balls are permanently lubricated with food-friendly grease. A labyrinth seal guards against dirt particles, but let pass penetrating fluids. They’ve got a fix point switching, which means one engagement/disengagement per 360°. All together the construction of the ECR gets along by using very few moving parts – that guarantees a high functional safety.

Combined with crown gear or chain wheel it is a compact device that must simply be put on the shaft of the machine. Special versions are available on request. ECR’s torque range is between 15 and 350 Nm.
