Abstract
A bearing including: an inner race; an outer race arranged to rotate freely relative to the inner race by a first plurality of rolling elements and including a circumferentially disposed channel arranged on a first radially outermost surface of the outer race; a cage located in the circumferentially disposed channel and including a first plurality of apertures; and a second plurality of rolling elements disposed in the first plurality of apertures.
Claims17
A bearing arranged to reduce friction between a housing and a rotating shaft, comprising:
- an inner race arranged to be mounted on the rotating shaft;
- an outer race assembly comprising:
- an outer race arranged to rotate freely relative to the inner race by a first plurality of rolling elements;
- a circumferentially disposed channel arranged on a first radially outermost surface of the outer race;
- a cage located in the circumferentially disposed channel and including a first plurality of apertures;
- and,
- a second plurality of rolling elements arranged in the first plurality of apertures and contacting the housing such that the bearing is movable relative to the housing.
A bearing arranged to reduce friction between a housing and a rotating shaft, comprising:
- an inner race arranged to be mounted on the rotating shaft;
- an outer race arranged to rotate freely relative to the inner race by a first plurality of rolling elements and including a circumferentially disposed channel arranged on a first radially outermost surface of the outer race;
- a cage located in the circumferentially disposed channel and including a first plurality of apertures and a second radially outermost surface;
- and,
- a second plurality of rolling elements, each rolling element in the plurality of rolling elements disposed in a respective aperture included in the first plurality of apertures and extending radially past the second radially outermost surface.
A method of reducing friction between a housing and a rotating shaft including a bearing, comprising:
- mounting an inner race on the rotating shaft;
- arranging an outer race to rotate freely relative to the inner race by a first plurality of rolling elements, the outer race including a circumferentially disposed channel arranged on a first radially outermost surface of the outer race;
- securing a cage in the circumferentially disposed channel, the cage including a first plurality of apertures;
- and,
- retaining a second plurality of rolling elements in the first plurality of apertures, the second plurality of rolling elements contacting the housing such that the bearing is movable relative to the housing.
