Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A flanged ring for fixing a bearing in place at least axially with respect to a machine component is in the form of a ring-shaped sheet metal element provided with a break at least at one place on the circumference of the annular metal element. The break defines two adjacently positioned end regions of the annular metal element and these end regions are adapted to be permanently connected to one another by way of an interlocking connection. The interlocking connection can be constituted by a portion of one end region extending towards or being punched out towards the other end region. Alternatively, the interlocking connection can be provided by a connecting element (e.g., a rivet) that extends through a bore in each of the end regions.

Abstract: 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.

According to one embodiment, the reinforcement body is poured in liquid form into the recess. The shrinkage of the reinforcement body that occurs during the cooling phase after solidification produces stresses as well.
