Dynamoelectric Machine Having Improved Lubricant Slinger

View page
US Patent:
45659370, Jan 21, 1986
Filed:
Feb 29, 1984
Appl. No.:
6/584622
Inventors:
Richard F. Uhen - Fort Wayne IN
Assignee:
General Electric Company - Fort Wayne IN
International Classification:
H02K 708
US Classification:
310 90
Abstract:
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, 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.

US Patent:
47814764, Nov 1, 1988
Filed:
Dec 11, 1986
Appl. No.:
6/940663
Inventors:
Richard F. Uhen - Fort Wayne IN
Assignee:
General Electric Company - Fort Wayne IN
International Classification:
F16C 1700
US Classification:
384136
Abstract:
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 flow at 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.
