Bender ABSTRACT: A device for retracting and aligning the brush members of a brush block assembly with respect to a slipring assembly, wherein a cylindrical member provided between the brush lock assembly and the slipring assembly has a plurality of slots for receiving the brush members, and an arcuate groove registering with each slot. The cylindrical member is rotatable with respect to the brush block assembly so that each brush member can be transferred into said groove to uniformly retract the brush members.
BRUSH BLOCK RETRACTOR AND ALIGNMENT DEVICE BACKGROUND OF THE INVENTION This invention relates to a brush block retractor and alignment device, and, more particularly, to such a device for insuring correct radial and longitudinal alignment of a series of brush members mounted on a brush block assembly.
There are many environments in which a plurality of electrical circuits must be maintained between a rotating member and a fixed member. For example, in the use of generators, acceleromcters, gyros, pulse loops, encoders, etc., a rotatable slipring assembly is often provided which has a series of grooves or the like formed therein for receiving a series of brushes, with each groove of the slipring and each brush member being connected within an electrical circuit. With the increasing emphasis on microcircuits, and the like, it has been extremely difficult to service the slipring assembly and/or brush block assembly due to the fact that once the brushes are in engagement with the grooves of the slipring assembly, it is extremely difficult to retract the brushes to permit removal of the slipring assembly for servicing and replacement, while still maintaining their original alignment.
According to the present methods of separating the slipring assembly from the brush block assembly, the brush members must be physically displaced by using an external tool while, after reassembly, the position of each brush member is visually observed through a boroscope, or the like, to ascertain its position. Any misaligned brush members must then be repositioned with a tweezerlike tool. In addition to this operation being extremely difficult, the brush members are easily damaged by the tools, and the displacement of the brush members is not controlled, often resulting in overstressed brush members and fatigue failure.
SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a device which permits the brush members to be easily retracted without any danger of misalignment or failure of the brush members, while eliminating the need for visual observation and external tools.
Briefly summarized, the device of the present invention comprises a cylindrical member disposed between a brush block assembly and a slipring assembly, said cylindrical member having a plurality of slots formed therethrough for receiving the brush members, and a groove registering with each slot, said cylindrical member being rotatable with respect to said brush block assembly to a position whereby each brush member is transferred into said groove, to uniformly retract said brush members.
BRIEF DESCRIPTION OF THE DRAWINGS Reference is now made to the accompanying drawings for a better understanding of the nature and objects of the present invention. The drawings illustrate the best mode presently contemplated for carrying out the objects of the invention and are not to be construed as restrictions or limitations on its scope. In the drawings:
FIG. I is a perspective view of the device of the present invention shown in use with a brush block and slipring assembly;
FIG. 2 is a fragmentary perspective view of the cylindrical member of the present invention;
FIG. 3 is a crosssectional view taken along the line 33 of FIG. 2;
FIG. 4 is a fragmentary perspective view of the slipring assembly;
FIG. 5 is a cross-sectional view taken along the line 5-5 of FIG. 4; and v FIG. 6 is a cross-sectional view taken along the line 6-6 of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS tion, a flattened top, and two elongated side windows. A tubular cam member 12 is disposed in the hollow portion of the brush block assembly and extends for the longitudinal length thereof. A tubular slipring assembly 14 extends within the hollow portion of the cam member 12, for the longitudinallength thereof. The slipring assembly is mounted in a known manner for high-speed rotation while the cam member may be rotated at least a limited distance with respect to the brush block assembly.
Two rows of brush members 16 are fixed within holes in the brush block assembly 10 with one end portion of each brush member extending into the hollow portion of the brush block assembly, and the other end portion extending outwardly from the top flattened portion thereof. The portion of each of the brush members 16 extending within the hollow portion of the brush block assembly engages the slipring assembly to permit one or more electrical circuits to be completed during rotation of the slipring assembly.
The cam member 12, shown in detail in FIG. 2 and in cross section in FIG. 3, has an outside diameter slightly less than the inside diameter of the brush block assembly and a plurality of axially spaced arcuate slots 18 formed therein which extend for approximately 45 and are alternately spaced apart. A plurality of arcuate grooves 20 are also formed in the outer surface of the cam member, and, as better shown in FIG. 3, each groove 20 extends for approximately 45 and registers with a corresponding slot 18. The grooves are also alternately spaced 180 apart, and the leading end of each groove has a smoothly tapered surface 22, for reasons that will be explained in detail later.
The slipring assembly 14, shown in detail in FIGS. 4 and 5, has a plurality of grooves 24 formed in the outer surface thereof, the floor of each groove having a substantially V- shape cross section. Also shown in these figures are the brush members 16 lying in every other groove on opposite sides of the slipring assembly, and an electrical conductor 26 electrically connected'to each of the grooves, with the conductors all extending through the slipring shaft to an external point.
The assembled components are shown in cross section in FIG. 6 with a brush member 16 being shown connected to an electrical conductor 28, and extending through the upper portion of the brush block assembly into a slot 18 formed in the cam member 12, and in a groove 24 formed in the slipring assembly 14.
In the event it is desired to separate the slipring assembly from the brush block assembly, the cam member 12 can merely be rotated in the direction indicated by the arrow A in FIG. 6; so that the tapered surface 22- at the leading edge of the groove 20 of the cam member engages and then forces its respective brush member 16 radially outwardly a controlled, uniform distance with respect to the slipring assembly, to permit separation of the two assemblies while maintaining an axial alignment of the brush members. After the assemblies It is understood that variations may be made in the above,
without departing from the invention. For example, the cam member may be a duel type permitting operation with a twobrush circuit arrangement. Also, the brush block assembly may be rotatable with respect to the slipring assembly.
Further, a single row of brush members may extend outwardly from the top and bottom of the brush block. Of course, other variations of the specific construction and arrangement of the brush block retractor and alignment device disclosed above can be made by those skilled in the art without departing from the invention as defined in the appended claims.
