A support roller assembly comprises a support roller formed at least in part as a hollow cylinder. At least two bearings are spaced from each other in the axial direction of the support roller and rotatably support the support roller. At least one cushioning element is disposed within the support roller in the axial spacing between the two bearings. The cushioning element includes at least one ring made of cushioning material that extends adjacent the inner surface of the support roller.

Support roller assembly

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.

Bearing arrangement for a load-bearing roller

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 bearing assembly () includes at least one bearing () that rotatably supports a cylindrical roller tube (). A cushioning layer () is disposed, directly or indirectly, between a ring () of the bearing () and the cylindrical roller tube (). At least one contact surface () for the cushioning layer () extends over a defined axial distance (L) at an angle (&#x3b1;) to the rotational axis (A) of the bearing assembly ().

Bearing assembly

A process for mounting an outer bearing ring involves press fitting a stamp into the outer ring so that the inner peripheral surface of the outer ring assumes the shape of the stamp. Using the stamp, the outer ring is then press fitted into the recess of a machine part so that the contour of the external peripheral surface of the outer ring is plastically molded through axial stretching into the machine part. To mount an inner ring, a stamp with a bore is press fitted onto the inner ring so that the inner peripheral surface of the inner ring pressing against the stamp assumes the shape of the bore of the stamp. Using the stamp, the inner ring is then press fitted onto the machine part and the contour of the inner peripheral surface of the inner ring is plastically molded through axial flow forming into the machine part.

Process for mounting bearing rings

A method for fixing at least one bearing in place in a bearing retainer involves positioning the bearing in the depression, providing an elastic element which acts in the axial direction on the bearing either before or after the bearing is positioned in the depression so that the elastic element is supported on the bearing in a first axial direction, and deforming a partial area of the bearing retainer so that the deformed partial area of the bearing retainer supports the elastic element in a second axial direction which extends opposite the first axial direction. A bearing arrangement produced according to the present invention includes a bearing retainer having at least one depression in which is positioned a bearing, with a portion of the bearing retainer overlapping a portion of the bearing to form an interlocking connection between the bearing retainer and the bearing in an axial direction. An elastic element is arranged in an area of the overlap of the bearing and the bearing retainer, and is supported on the bearing in a first axial direction while being supported on the bearing retainer in a second axial direction opposite to the first axial direction.

Bearing arrangement and method for fixing at least one bearing in place in a bearing retainer

A bearing ring includes a first ring part having a first peripheral surface forming a rolling body retaining track or a sliding surface and a second peripheral surface, and a concentrically arranged second ring part having first and second peripheral surfaces. The first and second ring parts are pressed together to plastically mold the second peripheral surface of the first ring part into the first peripheral surface of the second ring part through axial expansion. During manufacture, one tool grasps the first peripheral surface of the first ring part and presses it into a pre-determinable shape and another tool supports the second peripheral surface of the second ring part. The first ring part is pressed against the second ring part, with the contour of the second peripheral surface of the first ring part being plastically molded into the first peripheral surface of the second ring part through axial flow forming.

A method for fixing at least one bearing in a depression of a bearing retainer involves deforming a portion of the bearing retainer to cause a portion of the bearing retainer to form an overlapping connection of the bearing which axially retains the bearing in the depression. In the first stage of the two-stage deformation process, a first partial area of the bearing retainer is deformed compress the material forming the bearing retainer. In the second stage of the deformation process, a second partial area of the bearing retainer is deformed to form the overlapping connection, in the axial direction, between the bearing and the bearing retainer.

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 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.

A bearing plate formed from sheet metal to hold at least two rolling bearings in closely adjoining relation includes a pair of seat surfaces between which is located a ridge. The ridge is positioned in the area of the narrowest point between the outside rings of the rolling bearings and is pulled from the seat surfaces generally in the axial direction. The ridge axially increases in width with curved transition areas that merge with the seat surfaces.
