Embodiment Construction
[0016] Attached below Figure 1-4 An embodiment of the present invention is described.
[0017] A device for axially floating, radially pre-tightening and fixing the rotating body where the inertial element is located. It has a non-rotating body 1 and a rotating body 2. The inertial element 7 is installed in the rotating body 2. The lower end of the rotating body 2 is supported by the lower bearing 3 on the On the non-rotating body 1, and the lower bearing 3 is fixed in the lower bearing seat 4, the upper end of the rotating body 2 is supported on the non-rotating body 1 through the upper bearing 5, and when the rotating body 2 is heated or cold, the upper bearing 5 and the upper The bearing seat 6 is floatingly connected, specifically, the outer ring 9 of the upper bearing 5 is in clearance fit with the wall surface of the inner hole of the upper bearing seat 6 , and the upper bearing 5 is fixed on the rotating shaft 8 at the top of the rotating body 2 . At the same time, a ...
