Abstract
An example brush holder assembly for positioning a conductive carbon brush in contact with a conductive surface of an electrical device is disclosed. In some aspects, the example brush holder assembly includes a brush holder including a backbone extending therefrom and a removable handle. Further, the removeable handle includes a frame releasably engaged with the backbone and a grip secured to the frame. In some aspects, the brush holder assembly includes a removable catch arm removably coupled to an upper beam and a lower beam of the brush holder assembly. Removal of the catch arm allows the upper beam to be disassembled from the lower beam.
Claims22
A brush holder assembly for positioning a conductive carbon brush in contact with a conductive surface of an electrical device, comprising:
- a brush holder including a backbone extending therefrom;
- and
- a removable handle, wherein the removeable handle includes:
- a frame releasably engaged with the backbone;
- and
- a grip secured to the frame.
A removable handle for a brush holder assembly of an electrical device, comprising:
- a frame formed of a metallic material, the frame configured to slidably engage a backbone of the brush holder assembly;
- and
- a grip formed of a rubber or polymeric material, the grip molded around the frame.
A brush holder assembly, comprising:
- a lower beam;
- an upper beam pivotably coupled to the lower beam;
- and
- a removable catch arm including a first end region and a second end region;
- wherein the first end region of the catch arm is configured to attach to the upper beam;
- and
- wherein the second end region of the catch arm is configured to attach to the lower beam.
A brush holder assembly, comprising:
- an upper beam;
- a lower beam pivotably coupled to the upper beam;
- a brush holder attached to the lower beam, the brush holder including a first side wall and a second side wall;
- a carbon brush slidably disposed in the brush holder between the first side wall and the second side wall;
- wherein the first side wall, the second side wall or both the first side wall and the second side wall include a cut out in an upper edge thereof that extends downward toward a lower edge thereof;
- and
- a spring including a coiled portion configured to exert a downward force on an upper surface of the carbon brush.
A brush holder assembly, comprising:
- an upper beam;
- a lower beam pivotably coupled to the upper beam;
- a brush holder attached to the lower beam, the brush holder configured to slidably receive a carbon brush therein;
- wherein the lower beam includes a first sidewall and a second sidewall defining a channel therebetween, the channel configured to removably receive a mounting block to secure the brush holder assembly to an electrical device;
- wherein the first sidewall includes an opening extending through the sidewall into the channel.
