Description

BACKGROUND Drive arrangements, in particular electrical axes (E-axes), use bearing arrangements with rolling bearings. Shim rings can be used to compensate for bearing play in the rolling bearings and to bias the rolling bearings. For this purpose, the biased rolling bearings are measured while already mounted on the shaft (distance between the bearings). In addition, the corresponding bearing seat depths are measured. Then, considering various influencing factors and the desired biasing force, a thickness for the shim ring is calculated. This is mounted between the bearing and the bearing shoulder in the bearing seat. To mount the shim ring, it can be placed on the rolling bearing as the rolling bearing is pressed into the bearing seat. A disadvantage of this method is that the shim ring can easily slip, making this process step comparatively unstable. SUMMARY The invention proposes a method for mounting a rolling bearing of a bearing arrangement into a housing with a first housing part and a second housing part. The bearing arrangement may be a shaft with one or more rolling bearings, particularly two rolling bearings, each mounted on the shaft. The housing may be configured as a gear housing. The first housing part may be configured as a gear cover. The first housing part has an inner side and an outer side. A bearing seat for the rolling bearing is arranged or formed on the inner side of the first housing part. The method comprises the steps of: Providing the bearing arrangement with the rolling bearing.Positioning (or mounting) the bearing arrangement in the second housing part.Providing a shim ring.Positioning the shim ring on the bearing seat (or on the inner side of the first housing part). Holding (or fixing) the shim ring in the bearing seat (or on the inner side of the first housing part) by means of magnetic interaction. The shim ring can interact magnetically with a positioning device. Connecting (mounting) the first housing part to the second housing portion. In particular, closing the second housing part with the first housing part. As a result of the connection of the first housing part to the second housing part, the rolling bearing is pushed into the bearing seat. During the connection of the first housing part to the second housing part, the shim ring is held (or fixed) in the bearing seat (or on the inner side of the first housing part) by means of magnetic interaction, in particular with the positioning device. When the two housing parts are mounted on one another or connected to one another (“housing mounted”), the shim ring is located between the rolling bearing and the first housing part. The shim ring is held in the desired (final) position in the bearing seat by magnetic interaction, in particular shortly before and during mounting of the rolling bearing into the bearing seat. This allows the shim ring to be held in the desired position, in particular during mounting of the rolling bearing into the bearing seat, so that sliding of the shim ring can be prevented and secure mounting of the rolling bearing into the bearing seat can be ensured. According to a further development, the method may comprise at least one of the following steps: Outputting a signal when the position of the shim ring in the bearing seat (or on the inner side of the first housing part) deviates from a predetermined (desired) position. The signal may be an optical (e.g., red light) or an acoustic signal. Outputting a signal when the shim ring is arranged at the predetermined (desired) position in the bearing seat (or on the inner side of the first housing part). The signal can be an optical (e.g., green light) or an acoustic signal. This can indicate the correct or incorrect position of the shim ring by simple means. According to a further development, a positioning device as described in the following embodiments can be used to perform the method. With respect to the advantages that can be achieved in this way, reference is made to the explanations regarding the positioning device. The measures described and/or discussed below in connection with the positioning device can serve the further design of the method. According to the invention, a positioning device for positioning a shim ring is proposed for mounting a rolling bearing of a bearing arrangement into a housing with a first housing part and a second housing part. The bearing arrangement may be a shaft with one or more rolling bearings, particularly two rolling bearings, each mounted on the shaft. The housing may be configured as a gear housing. The first housing part may be configured as a gear cover. The first housing has an inner side and an outer side. A bearing seat for the rolling bearing is arranged or formed on the inner side of the first housing part. The positioning device includes at least one magnet. The positioning device can be positioned or arranged on the outer side of the first housing. The positioning device is configured so that when i
