摘要:
A bearing assembly is configured to be axially mountable in a support roller as a single structural unit. The support roller includes an at least partially hollow-cylindrical support roller shell and a support roller shaft. The bearing assembly comprises a mounting element configured to axially slide on the support roller shaft for mounting the bearing assembly in the support roller, a roller bearing having an inner ring fixedly supported on the mounting element, a support body radially surrounding the roller bearing, a cushioning layer radially surrounding the support body, and a sleeve radially surrounding the cushioning layer. The sleeve is configured to slidably contact an inner cylindrical surface of the support roller shell.

A bearing assembly (1) includes at least one bearing (3) that rotatably supports a cylindrical roller tube (2). A cushioning layer (5) is disposed, directly or indirectly, between a ring (4) of the bearing (3) and the cylindrical roller tube (2). At least one contact surface (6, 7) for the cushioning layer (5) extends over a defined axial distance (L) at an angle (α) to the rotational axis (A) of the bearing assembly (1).

A method for securing at least one bearing in a bearing plate provided with an indentation or recessed region for receiving a bearing involves partially swaging at least one positioning face on the bearing plate for accurately or precisely positioning a retaining baffle, positioning the retaining baffle against the at least one swaged positioning face, and materially bonding the retaining baffle to the bearing plate so that the retaining baffle exerts an axial force on a part of the bearing during operation of the bearing. A bearing arrangement includes a bearing plate provided with at least one indentation and at least one partially swaged positioning face, a bearing disposed in the at least one indentation, and a retaining baffle pressed against the positioning face of the bearing plate. The retaining baffle is materially bonded to the bearing plate and is positioned such that the retaining baffle exerts an axial force on a part of the bearing during operation of the bearing.

A fastening means for securing an annular first machine element against axial displacement on an annular second machine element, said second machine element having a shoulder against which the first machine element abuts and an annular groove spaced from said shoulder comprising a first ring member circumscribing the second machine element and having one axial end face confronting and abutting an axial end face of said first machine element and being formed to define an annular pocket, a second one-piece ring made of a deformable material which is initially sleeve-shape and is adapted to engage in the annular pocket and be deformed in a radial direction as a result of axially applied pressure during assembly into the annular pocket in such a way that a portion thereof engages in the annular groove in the second machine element to secure the two in place.

The arrangement according to the invention provides a sealing ring fastened to the end ring in a manner secure against removal by pulling or twisting. This sealing ring is provided with thickened extended arms and is fastened by snapping in the thickened arm sections behind an internal radial shoulder through openings in the flange of the end ring. The opening in the flange of the end ring may be economically manufactured, as by means of axial forms or cores, and without the need for additional radial cores, within the casting mold.

A clutch release bearing including cooperative inner and outer race rings with included rolling elements, and a holding ring having a first flange closely adjacent and facing a second flange of one of said rings, one of said two flanges having spiral grooves or other means for providing with a fluid hydraulic pressure between said flanges, thereby urging said inner and outer race rings together for maintaining a generally fixed axial relationship between them.
摘要:
A method for securing the outer ring of the bearing in a runner shell wherein the radius of an edge defining the seat for the bearing varies in a predetermined manner around its circumference, the steps comprising, positioning an outer ring of the bearing in the seat of the runner shell so that the edge of the runner shell overlies a circumferentially extending seating groove in the outer ring, placing a die having a forming face in engagement with the peripheral edge of the runner shell, and deforming by means of a die, the edge of the runner shell seat in a manner to displace essentially the same material around the circumference of the edge into the bearing groove, thereby producing a generally uniform force on the bearing ring around the circumference of the ring which eliminates distortion thereof.

The rolling bearing of a guide roller is held in the bore of a thin wall roller adapted to guide a pulley, by projections radially inwardly extending from the thin wall roller. The projections may be in the form of beads having planar surfaces in a plane normal to the axis of the bearing on the side facing the bearing, or they may be notches having one side thereof separating from the material of the roller to be forced radially inwardly to engage the sides of the bearing. The notches may be resilient, to enable the bearing to be snapped into position.

A process and apparatus for forming a cage part, for a ball bearing, wherein the cage parts are annular with alternate flat portions and ball receiving recesses. The cage parts are formed by pressing the rings from cage material such as steel. The flat portions are formed with axially extending rivet pins or holes for receiving the rivet pins of another cage part, in order to enable fastening of the cage parts together. The rivet pins are formed by pressing operation at the time as forming the cage part, by the flowing of the material of the cage part into recesses in a die.

Thin-walled bearing bushing produced in a drawing process for the support of pins in universal joints comprising an elongated generally cylindrical sleeve section and a bottom section forming an end closure at one axial end of said sleeve section, the juncture of the peripheral surface of said sleeve section and the outer axial end face of said bottom section defining an outer rim having at least portions of a small cross sectional radius (r), and means defining at least a pair of separate circumferentially extending spaced grooves in the bottom section adjacent said peripheral rim.
