Abstract: A positioning pivot including a shaft, at least one sleeve and at least one hinge butt is able to prolong its lifespan by inserting the sleeve between the shaft and the hinge butt after a combination of the shaft and the hinge butt is accomplished. Due to an opposite difference between an orientation of a helical slit defined in the sleeve and a helical groove defined in an outer periphery of the shaft, lubricant added to the helical groove is able to be disperse to other portions of the shaft when the sleeve is securely retained within the hinge butt and the shaft is rotated. Additionally, a portion of the shaft is configured to be hollow, so that even when a relationship between the portion and the sleeve is loosened, a dimension of the portion of the shaft is able to be enlarged by an adjusting element to regain tight relationship between the portion of the shaft and the sleeve again.

The first, second and third races cooperate to define an aperture therethrough to the shaft. A connector is disposed through the aperture to functionally interlink the first race, the second race and the shaft to insure that the first race and the second race rotate substantially with the shaft. In operation, the first and second races define a first bearing surface that accommodates angular displacements of the shaft, and the second and third races define a second bearing surface that accommodates axial and rotational movements of the shaft.

Abstract: A bearing assembly with thermal compensation including a rotor rotatably mounted to a stator by way of a bearing mechanism.

Abstract: A plain flanged bearing or bushing for supporting a rotating shaft in a thin walled frame of an electrophotographic printing machine. The composite bearing has a flanged end and is adapted to be inserted in an opening in a thin walled support member until the flange abuts the surface of the wall. A protruding tab formed by displacing a small portion of the flange extends in an axial direction along the bearing and cooperates with a corresponding opening in the wall to prevent rotation of the bearing. A friction push nut or snap ring is attached to the bearing on the side of the wall opposite the flange. The protruding tab prevents the bearing from rotating about an axis which can cause the bearing to be worn on the exterior surface by rotational contact with the thin wall. A shaft to support idler rolls or other rotating elements is inserted in an inner bore of the bearing and is rotatably supported thereby.

Abstract: A high pressure multi-stage centrifugal pump with an axially split casing (10) and a number of impellers (14) carried by a drive shaft (12) has inter-stage bushings (24) and rings (22) for sealing each side of each impeller. Each bushing (24) or ring (22) is conventionally prevented from rotating by a radial pin protruding from the lower half of the casing (10) into an axial slot in the periphery of the bushing or ring. The pin is necessarily small and is liable to shear, difficult to engage in the slot and, in cases where the bushing (24) or ring (22) is diametrically split, does not allow rotation of the lower half for its removal without lifting the shaft (12). To avoid all these disadvantages, without introducing any risk of leakage, a tangential pin (32) is fitted in a blind hole (34) in the casing (10) so that its exposed end (37) is flush with the joint face (28) of the casing and abuts against a shoulder ( 44) formed by a recess (38) in the periphery of the bushing (24) or ring (22).

Abstract: A rotating shaft has a ball bearing axially fixed on the shaft with a recess formed in the outer race. A detent device, urged radially toward the recess, cooperates with inclined flanks on axially opposite sides of the recess to produce a counterforce in response to axial displacement of the shaft without generating significant friction caused by rotation of the shaft. The detent device may have a spherical tip received in a conical or groove-shaped recess or it may be a rotatable roller received in a transversely oriented groove in the outer race.

Abstract: A spherical roller bearing is confined in a bearing ring which, in turn, is confined in a bearing housing, the housing and the ring each being of split construction. The housing has a pair of il reservoirs therein separated by a saddle upon which the ring is mounted, and an anti-rotation pin engages both the housing and the ring to prohibit rotation of the latter in the former. The ring, too, has an oil reservoir therewithin. The ring and pin, and accordingly the bearing, are electrically isolated from the housing. An oil ring rides upon a bearing-mounted motor shaft through slots formed in the bearing ring, and is guided by machined reliefs formed in opposite sides of the bearing ring. Holes in the saddle provide for a through-flow of oil between the pair of reservoirs in the housing.

Abstract: A bearing support member, mountable about a support stud, has two support arms extending toward side walls of a rocker arm.

The bearing cups may include a keyed shape to limit orientation of the bearing support member. Another aspect of the invention is a rocker arm subassembly having "open" bearing cups.

Abstract: A turbocharger includes a rotating shaft which is supported within the turbocharger center housing by rotational bearing elements. The bearing cartridge is located axially within the housing 14 by a pin which extends through orifices drilled in the center housing and in the bearing outer ring. The pin is relatively smooth, so that excursions of the bearing cartridge assembly with the shaft is permitted when the shaft is accelerated through critical rotational speeds. These excursions are damped by lubricating fluid communicated into grooves circumscribing the bearing outer ring through lubrication passages extending through the pin. The lubricating fluid in the grooves communicates into the intersticial space defined between the outer ring of the bearing cartridge assembly and the center housing to thereby dampen the excursions of the bearing cartridge assembly.

Sets of ball bearings are located between the inner race and each of the two outer races.
