ABSTRACT:
A self-contained slip ring assembly comprising a tubular rotor having sections of differing wall thicknesses supporting slip rings on the non-structural, thin-walled section. A thick-walled section supports those components requiring structural integrity such as the single bearing on which the non-rotating housing is mounted. The said bearing is held in position by clamping means thereby allowing easy disassembly for inspection or service. The said housing supports a generally cylindrical shaped brush block assembly utilizing a unique frictional creating means which permits the removal of the brush block assembly for inspection or service without the use of tools and, also, greatly simplifies the machining required for the housing body. An easily serviceable seal design is employed thereby permitting the matching of the seal to the environment in which the present invention is to be used.
