摘要

The machine i.e. electromotor (1), has a bearing (4) for supporting a rotor shaft (2) and arranged at a housing portion (5). A spring element (6) comprises a spring region (7) axially pre-stressing the bearing to the housing portion and another spring region (9) axially pre-stressing the rotor shaft. The former spring region comprises a set of spring arms (8) contacting with the bearing. The spring element comprises an inner ring connected to the latter spring region. The spring element is made of plastic material or steel. The spring element is designed as a single-piece element.
