A process for producing a bearing assembly includes positioning a first sleeve element in an injection mould, the injection mould having a cylindrical recess with a diameter for receiving the first sleeve element and the outside diameter of the first sleeve element being lesser than the diameter of the recess. A second sleeve element is positioned concentrically within the first sleeve element in the injection mould to define an annular chamber and elastomeric material in a molten state is injected under pressure into the annular chamber between the sleeve elements such that the outside diameter of the first sleeve element is expanded. The elastomeric material is allowed to solidify in the annular chamber between the two sleeve elements and the assembly of sleeves and elastomeric material are removed as a unit from the injection mould.

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.
摘要:
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 bearing arrangement (1) for a tension roller (2) designed as a hollow cylinder at least in segments, having at least one bearing (3) supporting the tension roller (2), wherein a damping layer (5) made of elastomer or rubber material is disposed between a ring (4) of the bearing (3) and the tension roller (2), directly or indirectly, and wherein at least one axial end of the tension roller (2) is closed by a cover (6). In order to achieve a low-noise and self-centering seal for the axial end of the tension roller, according to the invention, the cover (6) is disposed in a mounting segment (8) and is held by the same, said segment being molded from the material of the damping layer in an axial end region of the damping layer (5).

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).
