A grounding brush assembly includes a grounding brush and a mounting plate for the brush, the brush being provided with a plurality of conductive fibers and with a support inside of which the conductive fibers are housed. The mounting plate is secured to the support and is provided with a radially extending main body, retaining tongues for axially and radially holding the support, and with an axially extending centering portion. The mounting plate further includes at least one flange extending radially inwardly from a distal end of the axial portion.
Claims7
A grounding brush assembly for an electric motor, the motor including a shaft rotating about an axis, a fixed housing with a bore, and a bearing coupling the shaft with the bore, the grounding brush assembly including:
- a grounding brush including a support and a plurality of conductive fibers disposed at least partially within the support;
- and
- a brush mounting plate secured to the support of the brush and including a main body formed by a radial portion extending radially outwardly with respect to the support of the grounding brush, a plurality of centering tongues protruding axially from one side of the main body, each tongue locally radially surrounding and in radial contact with the support of the brush so as to hold the support axially against the main body of the mounting plate, a centering portion extending at least axially from the one side of the main body, having a distal end spaced axially from the main body and being offset radially outwardly with respect to the support of the brush and the centering tongues, the centering portion having an outer surface defining an outer diameter of the mounting plate and being configured to center the mounting plate within the bore of the housing of the electric motor, and at least one flange extending radially inwardly from the distal end of the centering portion.
