The fastening is for a bearing in an electrical machine casing. The machine is esp. a motor with a reducer driving wipers on a car windscreen. The fastening has at least one threaded bolt whose head rests against the bearing outer side, while its threaded shank freely passes through the bearing and is screwed into a nut held in a guiding element in the bearing, so that the nut rests against a stop on the casing. Guiding element (5) for the nut (4) consists of a slot open to the bearing outer side. It is cast on the bearing inner side and its inner outline matches the nut outer outline. The nut is a standard hexagonal nut, and the casing stop (6) is in the form of a projection on which the nut rests when the bolt (3) is tightened. |
