Abstract
Disclosed is a resilient member for use in a brush holder assembly. The resilient member may be positioned between at least a portion of a brush and at least a portion of a brush holder. For example, the resilient member may separate or isolate one or more sides of a brush from an adjacent surface of a brush holder. In some embodiments, the resilient member may prevent at least one side of a brush from impacting an adjacent surface of a brush holder. In some embodiments, the resilient member may be a conductive member forming an electrical pathway between the brush and the brush holder for transferring an electrical current between the brush and the brush holder.
Claims25
A brush holder assembly, comprising:
- a brush holder having an inner surface;
- a brush for placement in the brush holder, the brush including an outer surface;
- and
- a resilient member including a body portion having a first surface, a second surface, a third surface and a fourth surface, the resilient member including at least one resilient tab extending outwardly from each of the first, second, third and fourth outer surfaces of the body portion to engage the inner surface of the brush holder, the resilient member positionable between the outer surface of the brush and the inner surface of the brush holder to isolate the brush from direct contact with the inner surface of the brush holder;
- wherein the resilient tabs are flexible to absorb movement of the brush relative to the brush holder.
A resilient member for use in a brush holder assembly, the resilient member comprising:
- an open-ended sleeve having a peripheral wall extending from a first open end to a second open end of the sleeve, the peripheral wall including a first sidewall, a second sidewall, a third sidewall and a fourth sidewall, and one or more resilient tabs extending from each of the first, second, third and fourth sidewalls of the peripheral wall of the sleeve;
- wherein the sleeve is configured to be positioned between a surface of a brush and a surface of a brush holder to isolate the brush from direct contact with the brush holder.
A resilient member for use in a brush holder assembly including a brush holder having an inner surface and a brush having a top surface, a bottom surface, and four side surfaces, the resilient member comprising:
- a resilient sleeve including a first surface configured to face the inner surface of the brush holder and a second surface configured to be in contact with at least a portion of each of the four side surfaces of the brush, such that each of the four side surfaces of the brush is spaced away from the inner surface of the brush holder;
- wherein the resilient sleeve absorbs movements of the four side surfaces of the brush toward and away from the inner surface of the brush holder.
A brush holder assembly, comprising:
- a brush holder having an inner surface, the brush holder being removable from a mounting structure of an electrical machine;
- a brush disposed in the brush holder, the brush having a top surface, a bottom surface, and a plurality of side surfaces;
- and
- a resilient sleeve interposed between the brush holder and the brush to isolate the brush from direct contact with the inner surface of the brush holder, wherein the resilient sleeve includes an inner surface in contact with each of the plurality of side surfaces of the brush;
- wherein the resilient sleeve absorbs movements of the side surfaces of the brush toward and away from the inner surface of the brush holder.
