A shaped part made from a strip, peripherally contiguous ends of the strip being firmly connected to each other is characterized in that a recess () is arranged on one end of the strip () and an over-dimensioned projection () is arranged on the other end of the strip (), and after bending round of the strip (), said ends are fit into each other in axial or radial direction so that through a plastic deformation, an undetachable interference fit results between said ends.

Shaped part made from a strip

In a cage for cylindrical rolling bearings ( ), which cage is rolled out of a sheet metal strip ( ), the pockets ( ), as seen in a top view, have, in a profiled, punched and unbent state of the sheet metal strip ( ), a curved shape in a region of the inclined sections ( ), so that an axially inner, first convex curve B merges into an outer, second concave curve B This pocket contour of the invention makes it possible to obtain a separation between the retention of the rolling elements and the contact region of the rolling elements in the cage solely by the punching of the pockets in combination with a subsequent bending of the cage strip into a finished cage.

Rolling bearing cage

The invention relates to a window cage ( ) for a needle bearing. The pockets ( ) of said window cage are formed by punched out sections and by a stamping process with material displacement in a cage strip ( ) which is then bent round. According to the invention, the window cage ( ) is characterized in that before the cage strip ( ) is bent, the opposite surfaces of the web walls of a pocket ( ) are made up of three sub-surfaces ( ) in the area of the retaining projections ( ). The first two sub-surfaces ( ) follow a course which is parallel to a middle vertical ( ) and each extend into a second sub-surface ( ) at their upper end, said second sub-surface running diagonally in the direction of the central point of the pocket. Each of the second sub-surfaces then ends in a third sub-surface ( ) which also runs parallel to the middle vertical ( ).

Thrust rolling bearing

Radial roller bearing

A cage (1) for cylindrical rolling elements (5) comprising two side rings (2, 3) connected to each other by circumferentially uniformly spaced crossbars (4) so that receiving pockets (6) are formed for the rolling elements (5) is characterized in that opposing end surfaces (8) of the pockets (6) comprise projections (11) which extend inwards in axial direction and bear against end faces of the rolling elements (5) which prevents an axial offset between the rolling elements (5) and the cage (1) so that after insertion and suspension of the first rolling element (5), the cage (1) can be filled with the rest of the rolling elements (5) without their being damaged.

Cage for cylindrical rolling elements

An axial rolling bearing with a cage (2) comprising radially directed elastic projections (7, 8) on its inner and/or outer peripheral surface, which elastic projections (7, 8) bear against the collar (6, 5) of the race discs (4, 3) under all operating conditions of the bearing so that the cage (2) is radially centered, even if the shaft lifts off in axial direction.

Axial rolling bearing

A chiplessly formed bearing washer for a thrust bearing, comprising an angular thrust washer (1) comprising a radial portion (2) which forms a raceway and merges into at least one axial bend (3), said thrust bearing washer comprising a retention means in the form of projections (4) or recesses, the bent edges of the projections (4) or the edges of the recesses are provided with a stamping (7), whereby detrimental stresses occurring in the bent region are avoided.

Cage for full-type roller bearings

An axial beaing unit comprising two bearing discs (1, 2) with rolling elements (3) disposed therebetween, each of the bearing discs (1, 2) comprising an axially oriented cylindrical flange, which cylindrical flanges overlap each other in the axial direction, the flange of one of the bearing discs (1) being made as an overhanging flange (9) comprising a radially projecting end portion (3) at its free end (11), and the flange of the other bearing disc (2) being a retaining flange (10) comprising a retaining surface (14) facing the end portion (13), the end portion (13) engaging behind the retaining surface (14) so that the bearing discs are connected to each other secure against loss, characterized in that the radially projecting end portion (13) comprises several elastically yielding bosses (12) made without chip-removal and arranged spaced apart on the circumference of the end portion (13), which bosses (12) engage as a result of radial elastic relaxation behind the retaining surface (14).

Axial bearing unit

A rolling element cage made particularly of polymeric material in which rolling elements are guided in pockets and which is split at at least one point of its periphery, the cage ends delimiting the separating gap being formed by crossbars which comprise projections and corresponding recesses which fix these cage ends at least in the axial direction by interlocking, characterized in that the recesses in the crossbar forming the respective cage end extend into the adjacent pocket and, when the separating gap is closed, the projections projecting into the recesses extend at the most upto the delimiting surface of the pocket facing the cage end.

Split cage for rolling elements

An axial rolling bearing comprising a cage containing rolling elements and arranged between two plane-parallel, thin-walled bearing discs made of sheet metal, wherein the three components together form a structural unit by engaging together in a form-locking manner and at least one of the bearing discs merges at one of its peripheral edges into an axially directed collar which engages around the cage with clearance and extends into the region of the second bearing disc characterized in that there is a narrow guiding clearance at at least some peripheral points between the mutually facing peripheral surface of the collar and of the second bearing disc respectively.

An axial-radial rolling bearing comprising a first row of rolling elements which, for the absorption of axial forces are arranged between plane-parallel raceways of two race discs and a second row of rolling elements which, for the absorption of radial forces are arranged between flanges extending essentially axially and formed at adjacent peripheral edges of the race discs, characterized in that the flanges extend in different axial directions and overlap each other over at least a part of their length, the two rows of rolling elements being arranged radially one above the other substantially in one plane.

Axial-radial rolling bearings

A one-piece synthetic plastic cage for retention of clamping rollers in an overrunning roller clutch has two spaced-apart coaxial rims, axially parallel bars extending between the rims and defining roller pockets, and a discrete leaf spring for each bar. The springs are integral with one of the rims and are located radially outwardly of the corresponding bars so that they can bypass such bars by moving in the circumferential direction of the rims. One leg of each spring is integral with the one rim, and the other leg is integral with the one leg and has a free end which bears against the clamping roller in the corresponding pocket.
