Abstract
A bearing assembly includes an inner race, an outer race, a cage, and a plurality of balls. The inner race is configured to be coupled to a shaft. The cage includes a body having a plurality of projections and a plurality of openings. The cage is positioned between the inner race and the outer race, and is constructed from a corrosion-resistant and gall-resistant material. Each of the plurality of balls is received in an associated one of the plurality of openings, and the plurality of balls is positioned between the inner race and the outer race.
Claims20
A high-voltage electric switch comprising:
- a first electrical terminal configured to be supported on a frame member;
- a second electrical terminal configured to be supported on the frame member;
- a conducting member for providing electrical communication between the first electrical terminal and the second electrical terminal;
- and
- a shaft assembly supporting one of the first electrical terminal and the second electrical terminal for pivoting movement to move the conducting member between an open position and a closed position, the shaft assembly including a shaft and a bearing assembly supporting rotation of the shaft, the bearing assembly including,
- an inner race coupled to the shaft;
- an outer race;
- a cage including a body having a first side defining a plane, an inner edge defining an aperture for receiving the shaft, and a plurality of projections extending from the first side, wherein the projections have a wedge-shaped configuration and wherein an opening is formed between each of the plurality of projections;
- and
- a plurality of balls, with one of the plurality of balls being received in an associated one of the openings, the plurality of balls positioned between the inner race and the outer race.
