Abstract
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.
