ABSTRACT:
A method and apparatus for making an axially adjustable connection between a clutch shaft and an armature assembly to enable axial adjusting movement of the armature plate relative the inner body magnetic pole face to precisely set the air gap spacing through which an electromagnetic coil attracts the armature plate into frictional driving engagement with the inner body pole face. The hub of the armature assembly is placed upon the clutch shaft and a feeler gage is positioned between the pole face and the armature plate to establish the desired air gap spacing. An adjusting nut is threadedly advanced along a thread of the clutch shaft for progressive axial advance in the direction toward the inner body and engages the hub to maintain the armature assembly against air gap increasing movement away from the pole face. A retaining cap fits over the adjusting nut and engages with an offset abutment face on the shaft to retain the adjusting nut against further adjusting rotation in either direction relative the shaft. A plug member is threaded into a recess of the hub and engages with the end of the shaft to maintain the armature assembly against air gap decreasing movement toward the pole face subsequent to removal of the feeler gage. In the event of later disassembly of the electromagnetic clutch for maintenance or repair, the plug member, retaining cap and adjusting nut are removed. The plug member is then threadedly advanced into engagement with the end of the shaft and functions as a wheel puller facilitating disassembly of the armature assembly from the clutch shaft.
