方向に接合されている。FIG. 1 shows a bearing support device for a rotating machine according to the present invention. The support device shown in this figure is divided into a cylindrical bearing housing 2 that surrounds a bearing 1 and a bracket 8 that supports this, and a flange 2a is provided on the outer periphery of the bearing housing 2. This flange 2a is connected to an annular bracket 8f via a thermal expansion absorbing means 4 that absorbs the difference in thermal expansion in the radial direction. The thermal expansion absorbing means 4 consists of the above-mentioned thermal expansion difference (a fit that varies between a close fit and a close fit), and the flange 2a and the bracket 3 are joined in the axial direction by tightening the springs 5.

The flange 22a provided on the outer periphery of 2 and the annular bracket 2
8 are coupled via thermal expansion absorbing means 24. This thermal expansion absorbing means 24 is connected to the flange 22a in the radial direction (through a plurality of guide members 27 disposed in this direction) as shown in FIG. The guide member 27 is made of a round bar or a key, and the joint surface of the mounting plate 26 with the flange 22a is formed with a groove 26a that engages with the guide member 27. The flanges 22B are provided in a radial direction to ensure positional accuracy in the radial direction of the bearing housing 22. They are joined by tightening.

5 has no problem in terms of strength. The torque of the rotating machine can be received by the frictional force of the joint surface and the guide member 27.

効果が得られる。As described above, according to the present invention, in a bearing support device for a rotating machine, the bearing housing and the bracket are formed separately, and are connected through a thermal expansion absorbing means that absorbs the difference in thermal expansion in the radial direction. Since the bearing housing is constructed as follows, it is possible to release the radial expansion caused by the thermal expansion G of the bearing housing, thereby preventing an excessive load from being applied to the bearing housing.
