Abstract
A submersible electric motor for use in submersible pump or the like, in which an upright motor shaft is supported by upper and lower thrust bearings for supporting upward and downward thrust loads, respectively, and thrust pads of the upper and the lower thrust bearings receive upper and lower slide contact members secured to the motor shaft in its upper and lower portions, and in which resilient means such as coil springs or rubber bushings bias the thrust pads of the upper thrust bearing, suspension mounted to the motor frame, towards the upper thrust contact member secured to the motor shaft. This thrust bearing for supporting an upward thrust given to the motor shaft may be applicable to various electric motors.
