Abstract

522,668. Bearings. WOODS, Ltd., M. W., DIGGLE, T. R., and WHITFIELD, G. A. C. Feb. 14, 1939, No. 4843. [Class 12 (i)] The end plate 1 of the bearing structure of a small low starting torque electric motor is formed with an annular seating 4 to which may be secured either a thin metal diaphragm 5, Fig. 1, having a central depression 6 to constitute with a recess 7 in a central boss 2 on the plate. 1 a spherical seating for a self-aligning bearing sleeve 8 or a disc 10, Fig. 2, having a centre boss 11 bored to receive the outer race of a roller or ball bearing 12. The same screws are used to secure either a clamping ring 9 for the diaphragm 5 or the disc 10. Grease may be supplied to the ball bearing 12 through a bore 14 in the end plate leading to an annular recess 3 which communicated by a bore 15 with the recess 7. A thrower ring 13 may be provided between the inner ball race and a.shoulder on the motor shaft or the disc 10 may be continued inwardly to a small clearance around the shaft. A sleeve of synthetic resin, fibrous material such as leatheroid, rubber, or grease-resisting rubber substitute may be provided between the outer race and the disc 10. The sleeve 8 is preferably of porous self-oiling alloy but may be supplied with oil through the bore 14, the recess 3 and the space between the boss and the diaphragm 5 being filled with felt packing washers.
