Problems solved by technology

A disadvantage of this embodiment is that relatively weak automatic braking is achieved by the close point-like arrangement of the central thrust dome, wherein due to the wear of said thrust dome, the contact surface ( ) gradually increases during the service life

Embodiment Construction

[0019] exist figure 1 A thrust mushroom 10 according to the invention is shown in , as it is used to axially support a rotor shaft 58 of an electric machine 50 . The thrust mushroom 10 has an end face 12 which, in the assembled state, points towards the mating face 60 of the housing 56 of the electric motor 50 . A thrust surface 14 is formed on the end face 12 and is arranged at a distance from the axial center axis 20 of the thrust mushroom 10 . The contact surface 14 is designed as a circular ring 16 with an inner radius 21 and an outer radius 22 which are, for example, approximately 1.2 mm and approximately 2.4 mm. Formed radially within the annular contact surface 14 is a recess 18 whose outer radius 24 on the end face 12 corresponds to the inner radius 22 . The groove 18 preferably has a depth 26 of 0.5 mm to 1.5 mm and is suitable, in the installed state, as a container for a lubricant to lubricate the thrust surface 14 . In this exemplary embodiment, the recess 18 ha...

Abstract

A thrust mushroom-shaped part (10) used for axially supporting a rotor shaft (58) of a motor (50) is provided. The thrust mushroom-shaped part (10) is provided with an end face (12). A thrust surface (14) is configured on the end face and functions together with a matching face (60) of the motor (50) in an installation state. The thrust surface (14) is configured to be an annular shape. The motor is also provided by the invention and is provided with the thrust mushroom-shaped part (10).

Description

technical field [0001] The invention relates to a thrust mushroom according to the preambles of the independent claims and to an electric machine with such a thrust mushroom. Background technique [0002] DE 10 2007 018037 A discloses a thrust mushroom part of an electric motor, in which around a central spherical thrust dome (Anlaufkuppe) a lubricating grease pocket is arranged around it, which lubricating grease pocket is maintained throughout the operating period Grease is provided for lubricating the thrust dome. A disadvantage of this embodiment is that relatively weak automatic braking is achieved by the close point-like arrangement of the central thrust dome, wherein due to the wear of said thrust dome, the contact surface ( ) increases gradually during the service life. The effect of this automatic braking is therefore not constant over the service life, and therefore there are no predefined friction situations. Embodiments according to the invention should elimi...
