Title: End plates for electrical motors - are plates secured by bolts to arcuate sectors retained in annular groove
Inventor: GMELIN GUENTHER
IPC: F16B21/16
Filed: 1973-11-21
Abstract: An end plate for a motor is secured to cylindrical motor casing and supports the armature shaft via a ball bearing concentrically disposed within the end plate. Radially outside of the bearing on the end plate there is a cylindrical shoulder which cooperates with an annular groove in the casing to trap two arcuate sector plates. Bolts then pass through the end plate and engage in threaded bores in the sector plates thus retaining the end plate on the engine casing and preventing relative station of the end plate and casing. The bolts can also trap rubber mountings onto support structure for the motor. The arrangement avoids long bolts passing through the motor casing to secure both end plates and avoids the necessity for thick motor casings.

Title: Securing bearing race to shaft - by member wedged into circumferentially tapered gap between shaft and race
Inventor: KROST MANFRED
IPC: F16C35/073
Filed: 1974-01-10
Abstract: The bearing, being a ball bearing, has an axial extension of the inner race. The inner periphery of the extension is eccentric relative to the shaft and so forms the circumferentially tapered gap. A locking member inserted into the widest part of the gap is slid around the gap until it becomes wedged, thereby securing the race to the shaft. A peripheral groove between the race and the extension serves to guide the locking member and provides a line of weakening so that deformation of the extension on tightening of the member is not transmitted to the race.
