Abstract
A grounding brush includes a plurality of conductive fibers and a support inside which the conductive fibers are mounted. The support includes a mounting portion and two lateral flanks extending from the mounting portion and axially gripping the conductive fibers. Each lateral flank of the support has an internal frontal face and an external frontal face, the two faces delimiting the axial thickness of each lateral flank, and a bore. Each lateral flank of the support is further provided with a connecting surface extending between the internal frontal face and the bore.
Claims13
A grounding brush for an electric motor or electric machine, the grounding brush comprising:
- a plurality of conductive fibers;
- and
- a support inside of which the conductive fibers are mounted and including a mounting portion and two lateral flanks extending from the mounting portion and axially gripping the conductive fibers, each lateral flank including an internal frontal face, an external frontal face, an axial thickness delimited by the internal and external frontal faces, a bore and a connecting surface extending between the internal frontal face and the bore;
- wherein the connecting surface of each lateral flank of the support is convex so as to limit the risk of cutting the conductive fibers and each lateral flank terminates at the bore.
A grounding brush for an electric motor or electric machine, the grounding brush comprising:
- an annular support with a centerline and including a mounting portion with opposing axial ends and two lateral flanks extending radially inwardly from a separate one of the axial ends of the mounting portion such that an annular channel is defined between the two lateral flanks, each lateral flank including an internal face, an external face, an axial thickness defined between the internal and external faces, an inner circumferential surface defining a bore and a connecting surface extending between the internal face and the inner circumferential surface;
- and
- a plurality of conductive fibers spaced circumferentially about the centerline of the support, each conductive fiber having an outer radial end disposed within the annular channel of the support and an inner radial end contactable with a shaft;
- wherein the connecting surface of each lateral flank of the support is convex so as to limit the risk of cutting the conductive fibers and each lateral flank terminates at the bore.
