Abstract: The present invention comprises a spacer, especialy a spacer for use with a thrust roller bearing assembly. An internal radial lip projecting into the central aperture of the spacer provides for frictional retention on a shaft passing therethrough. Where the thrust bearing and spacer combination is to be installed in a bore, one or more external radial lips may be included to frictionally retain the spacer within the bore. The spacer element is adapted for coupling to one of the bearing elements. In one embodiment, the bearing and spacer may be bonded together. In another embodiment, the spacer and bearing are joined by mutually engageable circumferential locking surfaces. The spacer is selected from a plurality of spacers of differing axial dimension, each spacer being color coded according to its axial dimension.

Abstract: A shim is used to adjust camber in a wheel mounted on a suspension assembly that has a mounting plate with an opening for a drive axle for mounting both a brake caliper and a hub and wheel bearing assembly associated with the wheel. The shim has a central shim body tapered to define a shim angle. The shim body has a drive axle opening therethrough and a plurality of openings for fasteners connecting the hub and wheel bearing assembly to the mounting plate. At least one brake caliper lobe extends from the central shim body and provides an extension of the central shim body defining the same shim angle as the shim body. The lobe further has an opening therethrough for a fastener connecting the brake caliper to the mounting plate. The shim is interposed between the mounting plate, on the one hand, and the disk brake caliper and hub and wheel bearing assembly, on the other hand, to adjust the angle of both by the defined shim angle.

A first plurlaity of shim plates within the housing is positioned on one side of the plunger. A second plurality of shim plates is positioned on the other side of the plunger. When adjustment is needed, a shim plate can be removed from the first plurality and added to the second plurality. This arrangement of components provides a convenient storage for shim plates needed for adjustment.

Abstract: A dynamoelectric machine in the form of a windshield wiper motor having an armature shaft with a worm driving a worm gear mounted in a gear end housing. The armature shaft bearing is positioned against a shoulder on the shaft by a washer and push-on retainer. The bearing is slip-fit mounted in the gear end housing and a U-shaped retainer is mounted in a slot in the gear end housing adjacent the bearing such that the retainer engages the bearing to retain it against axial loading on the shaft. A bowed washer is mounted to engage the bearing to urge it against the retainer.

Abstract: The invention concerns a structure for mounting a fan to a fan motor. The structure is designed to fit a plurality of thrust washers onto the end of a motor shaft supported in a casing through a bearing and to thrust and fit a flat washer on a peripheral surface of a smaller diameter step formed on the tip side further than the washers-fitted section. Of these thrust washers, the most outer, tip side, thrust washer located opposite to the flat washer is thicker than the traveling play distance toward the core of a motor shaft and thinner than the interval from the adjacent thrust washer to the peripheral surface of the step. With the construction, hence, the invention serves to prevent the thrust washer from falling onto the smaller diameter step.

Abstract: A replaceable shim is provided for a planetary gear arrangement of the type having planetary gears each of which is rotatably mounted to a frame by a shaft. The shim includes an elongated flat body having a generally U-shaped recess at one end and which is adapted to be inserted in between the planetary gear and the frame so that the shaft is positioned within the U-shaped recess. The opposite end of the shim is then pivotal to a position in which the opposite end abuts against a portion of the frame thus locking the shaft in the U-shaped recess on the shim body. A bendable locking tab is then bent to a position in which the bending tab abuts against a second surface on the frame and prevents further pivotting of the shim. In doing so, the bending tab locks the shim to the frame with the planetary gear shaft positioned within the shim recess.

Abstract: A first shim mounted on the shaft extending from the high pressure end face of a screw rotor in a screw compressor establishes the operating clearance between the high pressure end face of the rotor and the high pressure end wall of the compressor's working chamber by fixing the axial position of a bearing group which is likewise mounted on the rotor shaft. A second shim, disposed between the bearing group and a spring biased spacer element, is determinative of the distance the spacer element, and therefore the rotor, can travel in a direction toward the high pressure end of the compressor under the impetus of reverse axial thrust. Contact of the rotor with the high pressure end wall of the working chamber is positively precluded because movement of the spacer element, under the influence of rotor movement toward the high pressure end of the compressor, collapses the biasing spring which causes the spacer element to contact a fixed surface of the compressor.

The axial bore cylindrical surfaces are in registry with the spring cup cylindrical surface. The registering cylindrical surfaces of the spring cup and axial bore have dimensions of close correspondence to ensure a snug fit of the spring cup within the axial bore.

Moreover, the pivot itself is arced along its length to further increase the pivotal capabilities of the shoe for more accurate alignment with the rotating surface of the rotary member.
