초록 ▼

A support device and method for fixing a bearing on a bearing shield of a housing of an electric machine. Rotatably mounted in the support device is a rotor with a shaft. The support device is substantially flat and comprises a plurality of fastening openings that are grouped about a central opening. The support device comprises at least one design break point that acts to provide a local limit to the excess stress in the material of the support device.

1. A method for fixing a bearing (28) in an electric machine (10) to limit oscillating accelerations during operation of the electric machine (10), the method comprising: providing a support plate (60) with a flat shape and at least one notch (66, 68; 72, 74; 76, 78; 92), the support plate (60) having a plurality of fastening openings (62) disposed around a central opening (64);coupling the support plate (60), having the at least one notch (66, 68; 72, 74; 76, 78; 92) already formed therein, to a bearing plate (13.1, 13.2) of a housing (13) of the electric machine (10), in which a rotor (20) with a shaft (27) is rotatably mounted, the support plate (60) being fastened to the bearing plate (13.1) via the plurality of fastening openings (62) and a corresponding plurality of fasteners to secure the bearing (28) within a mount in the bearing plate (13.1); andoperating the electric machine (10) such that oscillations of the rotor (20) act on the support plate (60), whereby a crack (70) is formed and as a result the support plate (60) at least partially fractures at the notch,characterized in that, during formation of the crack (70), surfaces arise that delimit the crack (70) and said surfaces rub against each other and damping work is thereby performed. 2. The method according to claim 1, characterized in that the at least one notch includes a notch (92) provided on a planar side (94, 96) of the support plate (60). 3. The method according to claim 1, characterized in that the at least one notch includes a notch (66, 68) provided on an outer edge of the support plate (60). 4. The method according to claim 1, characterized in that the at least one notch includes a plurality of notches provided on one or both of an outer edge of the support plate (60) and an inner diameter (80) of the central opening (64) of the support plate (60). 5. The method according to claim 4, characterized in that the plurality of notches includes at least two notches provided in diametric opposition on the outer edge of the support plate (60). 6. The method according to claim 4, characterized in that the plurality of notches includes at least two notches provided in diametric opposition on the inner diameter (80) of the central opening (64). 7. The method according to claim 1, further comprising, providing the support plate (60) with a taper (84) in which taper webs (86) extend, and plastically deforming the taper webs (86) during operation of the electric machine (10). 8. The method according to claim 1, characterized in that the at least one notch has a diametral quotient Kt>2.0. 9. The method according to claim 1, characterized in that a rigidity of the support plate (60) is reduced by the at least partial fracture of the support plate (60) during operation of the electric machine (10), and the support plate (60) further deforms more severely.
