Drive Shaft Assembly. The drive shaft assembly (15) consists of a flexible splined shaft and a friction damper

mechanism (16). Flexibility is obtained with damper mechanism to absorb sharp peaks which may occur in

the drive torque. Friction damper pressure is adjustable.

d. Armature. Armature (19) rotates in a pair of ball bearings (11 and 18). Both bearings are sealed and

permanently lubricated.

e. Cooling Air. The flow of cooling air is provided by a fan (10) driven by the armature, by an electrically driven

axial fan (on 10889713) or by a remote source of air ducted to the end bell (8) (on 11642898).
