Abstract

A tapered roller bearing with a separate outer race is used to axially align the rotor in a slidable rotor motor. It also serves as a combination thrust and radial bearing. Rotor 1 of motor 2 is free to move longitudinally on bushings 3 and 4. When motor field windings 5 are energized, rotor 1 is pulled into alignment with field core 6. Roller bearing 7, including inner race 8 and caged tapered rollers 9, contacts outer race 10. The latter is rigidly mounted to end housing 11, providing axial alignment for rotor 1. As rotor 1 rotates, bearing 7 serves as both a thrust and a radial bearing. Bushing 4 fits loosely to provide clearance when radial positioning of rotor 1 is controlled by bearing 7. When windings 5 are de-energized, bias spring 12 returns rotor 1 to its initial position.
