Description
The OLK electromagnetic clutch a clutch from the German company PRECIMA, is a positive, i.e. current-operated clutch.
When a DC voltage is applied to the coil, a magnetic field is generated which passes through the friction-lined rotor and attracts the armature, transmitting the movement.
When no current is applied, the diaphragm spring retracts the armature, thereby disengaging the clutch and no longer transmitting motion.
The OLK electromagnetic clutch is characterized by having 3 different construction types:
Construction 0: This is the basic clutch unit, consisting of the armature, rotor and armature, with riveted diaphragm spring to be mounted directly on the pulley or pinion.
Construction L: Consists of the armature, rotor, armature with riveted diaphragm spring and pulley bushing or sprocket.
Construction F1: Consists of the armature, the rotor, the armature with riveted diaphragm spring and the aluminium bushing for mounting on another shaft.
