状態において完全な円の外形をしてる。A fixing method for a rolling bearing in which an intermediate bush is provided between an outer ring and a housing is already known from German Utility Model Registration No. 8531659. The intermediate bush is flanged on the end face of the tubular housing part. The flange has a complete circular outer shape when the intermediate bush is assembled.
上述の公知の中間ブッシュは完全な円の外形をなすフ
ランジで管状のハウジング部分の全端面を覆っている。
このため、かかる軸受を分解する際に、軸受を押し出す
ための押圧装置を設置することが困難である。The known intermediate bushing described above covers the entire end surface of the tubular housing part with a flange having the shape of a perfect circle.
For this reason, when disassembling such a bearing, it is difficult to install a pressing device for pushing the bearing.
本発明の目的は、冒頭に述べた形式の中間ブッシュ

から押出装置によって押し出すことができる。According to the invention, this object is achieved in that the flange of the intermediate bush has a breakable part, which breakable part breaks the breakable part and removes part of the flange to form a tubular housing part. This can be achieved by being set at a position where the end face is exposed. By so forming the intermediate bushing, a support device can be mounted on the exposed end face of the tubular housing and the bearing can be pushed out of the housing bore by an extrusion device.

Provided and positioned parallel to each other. In addition, the flange has a longitudinal groove extending in the direction of the chord in the central area of the chord in the segment part, on the face opposite the bearing. This makes it possible to insert a tool, for example a screwdriver, into the longitudinal groove and break the segment.
