LUBRICANT SLINGER FOR AN ELECTRIC MOTOR AND METHOD OF ASSEMBLING SAME ABSTRACT OF THE DISCLOSURE A lubricant slinger mechanism for preventing the loss of oil or other lubricant which is pumped between the rotor shaft and bearing in an electric motor or other dynamoelectric machine. The slinger is mounted to the rotor shaft and mounted adjacent the end of the bearing out of which oil flows as it is pumped along the shaft from the reservoir. The slinger initially throws the oil radially outward against an inner oil well cover, and the provision of an impeller, such as a spiral vane on the outer peripheral surface of the slinger, imparts an axial component of velocity to the lubricant which impels it rearwardly toward the reservoir and prevents the migration of oil out of the forward end of the oil cover through which the rotor shaft extends. The slinger, in one form thereof, includes an annular cup portion which overhangs the end of the bearing so that lubricant is thrown off the slinger at a point rearwardly of the end of the bearing. The slinger is preferably formed with an opening that is larger in diameter than the shaft and includes a tapered surface on one end so that as the brass rotor sleeve is inserted into it, it centers the slinger and enables the brass sleeve to be pressed therein by means of automatic assembly machinery.
