Abstract: A sealing relationship between a rotatable and stationary member is formed by a seal arrangement between the rotatable and stationary member wherein a first member engages the seals forming the sealing relationship and a second member is rotatable by the rotatable member to rotate the first member about the stationary member at a substantially reduced rotational speed relative to the rotational speed of the rotatable member to inhibit damage to the sealing relationship.

Abstract: A tapered roller bearing has its rollers guided between radially outwardly projecting lips at the small side and large side of the bearing inner ring. A cage for the bearing includes webs for separating adjacent rollers and includes a small side ring, with radially inward projections at the webs which are snapped behind the lip at the small side of the inner ring. The small side ring of the cage comprises approximately radially directed undulations with radially outward crests between the cage webs.

Abstract: A roller clutch in which the rollers are retained in tightly fitting cars that latch to the cage to give a highly secure shipping retention, but which unlatch at outer race ring in to free the cars and rollers, At overrun, the friction of the rollers within the tightly fitting cars reduces roller spin and consequent cam wear.

Abstract: A tapered roller bearing has an outer ring and an inner ring, a row of rollers between the rings and a cage or separator. The inner ring has spaced apart flanges or lips between which the rollers move. The cage includes an annular ring at the radially smaller side which has undulations circumferentially around that ring. The indulations have axially inwardly directed crests that rest against and are pretensioned to urge the rollers toward the other inner ring flange. The webs of the cage between neighboring rollers have radial projections which engage the flange at the radially smaller side of the bearing. The distance between the plane which passes through the axial end surfaces of those radial projections and the plane which is defined by the tips of the undulation crests against the ends of the rollers is slightly greater than the difference between the distance apart of the flanges and the length of the rollers between the flanges.

Abstract: The roller cage of a roller bearing has lubrication grooves extending at an angle across the radially inside surface of one of the cage annular end rings.

Abstract: An overrunning roller brake, in particular for automatic transmissions for motor vehicles having a brake race fixed to the gearbox casing, a rotating brake race connected to one element of a planetary gear unit and overrunning brake rollers arranged between the two bearing raced wherein support rings with a C-shaped cross-section are disposed between the races, the rotating brake race being in the form of a one-piece extrusion which forms both the rotating outer brake race of the overrunning roller brake and a friction brake drum for the gear unit, and retainer rings within the support rings for accommodating radial loads and for stabilizing the outer race.

Abstract: A window cage for a cylindrical roller bearing includes a U-shaped cross section, annular cage having opposite cage rings which engage the ends of the rollers and webs joining the cage rings and extending between the rollers. The opposite sides of each web converge in the radial direction inwardly of the pocket recesses for the rollers. Therefore, spaced apart, opposing sides of two adjacent webs converge in the radial direction outwardly of the pocket recesses to engage a roller in the recess from behind. Radially outward beyond the converging surfaces, the web sides have generally parallel surfaces which are spaced apart slightly less than the diameter of the roller. Recesses are defined in the cage rings at the bottoms of the pocket recesses.

The layer hard material is formed by ionic spray discharge or ion implanation and consists of chromium nitride.

Abstract: An arrangement of roller elements which are guided by means of a guide ring and are arranged between two support rings in which, to reduce the coefficient of friction, deformations are allowed in order to eliminate slippage and decrease friction. The roller elements are each rotatably mounted on and/or by a shaft, and the guide ring is formed to be resilient or yieldable, so that the guide elements can make movements relative to each other. The arrangement is primarily designed as a radial bearing or an axial bearing and can additionally be designed as a frictional drive or transmission.

Abstract: A taper roller bearing is described which has the particular feature of having the track of the inner ring capable of being inspected, such characteristic is obtained by means of a spacer cage the bridges of which extend both above and below the roller pitch circle identified by the axes of the rollers in such a way as to retain these latter in the pockets of the cage both on the outer ring side and on the inner ring side of the bearing; the cage in the pockets of which the rollers are snap-engageable, is removable together with the rollers of the track of the inner ring, being axially fixed to this latter by snap-engagement.

Abstract: A cage for a tapered roller bearing includes a small diameter ring, a large diameter ring and circumferentially spaced arms joining the rings and defining pockets for the tapered rollers. The inwardly facing opposite surfaces of the arms in a pocket including an axial region adjoining the large diameter ring, which is also radially outside of the mold parting line developed during the formation of the cage. Those surfaces of the arms in the region adjoining the large side ring of the cage are shaped to the roller within the packet. In each cylindrical sectional plane through the bearing, which also passes through each of the rollers and is parallel to the axis of the bearing, the distance apart of the surfaces of the arms is approximately the length of a chord of the largest diameter of the roller in that cylindrical sectional plane.

Abstract: A cage for the rollers in a roller bearing in which the roller axes (2) define an angle with the bearing axis (3) has two annular portions (4, 5) and intermediate cage bars (6) defining cage pockets (7). The bars are situated radially inside of the roller axes with respect to the bearing and a flange (8) for guiding the roller by contacting their ends is extending radially outwards from one of the annular portions (4). A protrusion (9) is arranged on the flange (8) in connection to each pocket (7) or insertion into a recess in the adjacent roller end and thereby keeping the roller in the cage pocket. A recess (10) in the other annular portion (5) opposite each protrusion (9) simplifies the snapping of the roller into its pocket in the cage.

Abstract: The invention relates to cages for tapered roller bearings, which are guided on the rolling path of the external ring and thereby, in contrast to known constructions with internal flange guidance or rolling body guidance, are provided with a considerable improvement of the guidance quality. The cage guidance on the spherically configured rolling paths of the external ring results in better lubricating conditions because of an approximately slightly wedge-shaped guide slit, whereby the admissible upper limit of the rotational speed of the tapered roller bearings is considerably increased.

Portions of the lugs provided on bearing cage webs are staked to a preselected depth and a desired retainer conformation in an overlying relationship with adjacent roller receiving pockets in the cage. A punch assembly which accommodates a pair of simultaneous staking operations is employed. The assembly includes a staking punch configured to stake portions of the same lug in opposite directions from each other overlying portions of adjacent receiving pockets or to stake portions of adjacent lugs in opposite directions toward each other overlying opposed sides of the same receiving pocket.

Abstract: In a plastic retainer for roller bearing comprising first and second annular members disposed in axially spaced apart relationship, a plurality of posts containing the annular members and disposed circumferentially equidistantly, and a pocket for containing a roller formed between two adjacent posts and the annular members, the side surface of the post forming the pocket which is adjacent to the first annular member has a planar portion, the connecting portion between the planar portion and the first annular member provides a curved surface concave toward the pocket, and the radius of curvature of the curved surface is minimum on the pitch circle of the roller and is greater toward at least one side of the radial direction of the retainer.

Abstract: A bearing assembly for supporting the spindle of a machine tool includes a single row tapered roller bearing and a closure at each end of the bearing for isolating the interior of the bearing from the surrounding atmosphere. A liquid refrigerant and lubricating oil are mixed in the closure at the small ends of the rollers, and are directed into the space between the tapered raceways. This refrigerant, upon encountering the tapered rollers, the raceways along which the rollers roll, and the thrust rib against which the large ends of the rollers bear, vaporizes and extracts heat from those bearing components, thereby enabling the bearing to operate at a generally uniform temperature close to room temperature. The vaporized refrigerant flows through a port in the closure at the large ends of the rollers and then into a heat exchanger where it is condensed, the liquid refrigerant being then directed to the closure at the small ends of the rollers.

Abstract: An improved tapered roller bearing in which a shoulder at a small diameter end side of an inner race has been eliminated. A shoulder portion for maintaining a state of engagement between an inner race and a cage for holding tapered rollers at circumferentially equally spaced positions after assembling, is formed at an outer peripheral portion of a large diameter side of the inner race. Furthermore, projections for engagement with the shoulder portion are formed in positions not hindering the assembling of the tapered rollers at the large diameter side of the cage.

Abstract: A roller bearing comprising an annular outer track and a roller cage for itioning shoulderless, self-aligning roller bearings for high loads is disclosed. The cage is a window cage. It supports two annular rows of bearing rollers so that the inner end surfaces of the rollers are almost in engagement with each other. The cage is circular, but is elastically deformable for insertion in the bearing. The axially inner cage ring part between the two rows of rollers extends parallel to the race of the outer ring and lies practically against it. Over the entire circumference and across the entire width of the inner cage ring part, its outer surface is provided with spaced apart indentations which may include lubricant in them. The axially outer cage ring parts extend radially to the inner bearing race ring. The cage is preferably made of a hardened but elastic steel plate and is a single piece for at least one of the annular rows of rollers.

Abstract: This specification discloses a method of manufacturing a retainer for solid type roller bearing, a retainer manufactured by the method, and a cutting edge member used in the method. The specification also discloses the formation of roller retaining pawls around a roller retaining hole by cutting and removing post-like projections over a predetermined length by the cutting edge member, the post-like projections being formed on the wall surfaces of rectangular holes of a ring-like retainer member.

Abstract: A split roller bearing comprises a split inner race having a radially outwardly directed inner race surface, a split outer race surrounding the inner race and having an inwardly directed outer race surface generally concentric with the inner race surface, an annular row of rollers engaged radially between the inner and outer race surfaces, and a plurality of similar roller cage parts together forming an annular roller cage lying mainly between the inner and outer surfaces and formed with respective radially opening windows receiving the rollers. The cage parts each have a radius of curvature smaller than the radius of curvature of the inner surface in an unstressed condition. Thus it is possible to provide adequate material thickness at the ends of the cage parts to prevent the cage from wearing out at these locations. Since the rollers are movable radially in the pockets there is no binding between the rollers and the cage.
