Fig. 3 is a sectional view of the lower part of a device with a built-in vertical rotating body, showing only the main parts of the rotating body assembly device according to the present invention. .3rd
The difference from the structure in Figure 2 in Figure (=) is that a gap 11 is provided between the part of the bearing bracket 6 near the center of the bottom facing the part housing the bearing 5 and the common pedestal 1. , the wall thickness of the bearing bracket 6 in that part is reduced so that its natural frequency is also smaller than the vertical natural frequency of the common pedestal 1 (there are two points).

薄肉部の上下振動として吸収、減衰されてしまう。Therefore, according to the present invention, even if abnormal vertical vibration occurs in the rotating body 9 due to a malfunction in one of the plurality of devices 2, the vibration is transmitted through the shaft 8, the bearing 5, and the bearing bracket 6. In addition, the wall thickness of the bearing housing part of the bearing bracket 6 is reduced to have a solid collapse frequency smaller than the vertical natural frequency of the common pedestal 1. Therefore, the abnormal vibration occurs when the common frame 1
(- It is absorbed and attenuated as vertical vibration of the thin portion of the bearing bracket 6 without being propagated.
従って上記のような事態が生じても共通架台１を通して
他の機器２（−悪影響を及ぼすことはない。Therefore, even if the above-mentioned situation occurs, there will be no adverse effect on other devices 2 (-) through the common pedestal 1.
