Air gap adjuster for electric clutches

摘要

An electromagnetic clutch device for torque transmission from an input means to an output means which incorporates an air gap adjustment feature between the pole faces and the armature during assembly of the clutch. The air gap adjuster permits the armature to be responsive to magnetic flux formed by a predetermined electromagnetic coil voltage without having to tear down the assembly if the predetermined coil voltage is exceeded at initial try-out. Means are also incorporated to compensate for wear of the torque transmitting material.
