摘要： With a motor having a motor housing and a motor shaft, a sleeve of predetermined length is mounted on the motor shaft with a proximal end of the sleeve engaging against a bearing that is mounted in the motor housing and supports the shaft for rotation. The bearing and the sleeve function to simplify the construction of the motor by eliminating a retainer ring and its associated annular groove from the shaft that were previously necessary to hold the shaft and bearing in relative positions, and by eliminating an additional retainer ring and its associated annular groove from the shaft that were used as a locator to positively locate a machined surface on the motor housing relative to the shaft and to positively locate a rotating component on the end of the shaft.

摘要： A fan drive and water slinger seal for a vertically mounted electrical motor. A fan is placed on a motor shaft so opposing flats on the interior surface of the fan hub fan mater with corresponding flats on the shaft to prevent slippage between the fan and shaft during motor operation. The hub contains a spring like finger extending upward axially along a groove in the inner wall of the hub and engaging an annular groove on the shaft to prevent axial movement of the fan along the shaft. The fan is positioned between a motor endshield and an overlying drip pan which encircles the shaft and carries liquid away from the motor. A flexible slinger snugly and adheringly fits on the shaft and has an O-ring type interior seal for sealing within a second annular groove on the motor shaft. The outer peripheral edge of the slinger curves downward creating a peripheral, cylindrical lip which overhangs an upwardly extending lip about the periphery of the opening in the pan through which the motor shaft passes, the overhang preventing liquid from reaching the motor.

摘要： An improved drain structure for a vertically mounted electric motor to be positioned below a liquid sump into which the rotor shaft of the motor can be connected including a drip pan through which the rotor shaft passes, the pan having peripheral side walls and drain means attached thereto and a liquid slinger above the pan adapted to sling liquid leakage in a radially outward direction below the pan side walls to be drained away from the motor.
