specific Embodiment approach 1
[0018] Specific implementation mode one: see figure 1 Describe this embodiment, a method for suppressing the vibration of the rotating shaft system described in this embodiment, the method is realized based on the rotating shaft system, and the rotating shaft system includes a rotating shaft 1, a base 2, and two bearings 3 , middle spacer 4, outer ring preload gasket 6, end cap 7, inner ring preload gasket 8 and two preload nuts 9; the specific process of the method is:
[0019] Step A1: Add a piezoelectric adjustment ring 5 in the rotating shaft system,
[0020] The rotating shaft 1 is rotationally connected with the base 2 through two bearings 3;
[0021] The middle spacer 4 is arranged between the two bearings 3, and the two sides of the middle spacer 4 are respectively in contact with the inner rings of the two bearings 3; the outer ring of the right bearing 3 is in contact with the shaft shoulder on the base 2, and the right The inner ring of the side bearing 3 is in co...
specific Embodiment approach 2
[0028] Specific implementation mode two: see figure 1 This embodiment is described. The difference between this embodiment and the method for suppressing the vibration of the rotating shaft system described in the first embodiment is that the intermediate spacer 4 is a piezoelectric adjustment ring.
specific Embodiment approach 3
[0029] Specific implementation mode three: see figure 2 Describe this embodiment, a method for suppressing the vibration of the rotating shaft system described in this embodiment, the method is realized based on the rotating shaft system, and the rotating shaft system includes a rotating shaft 1, a base 2, and two bearings 3 , middle spacer 4, outer ring preload gasket 6, end cap 7, inner ring preload gasket 8 and two preload nuts 9; the specific process of the method is:
[0030] Step A1: Add a piezoelectric adjustment ring 5 in the rotating shaft system,
[0031] The rotating shaft 1 is rotationally connected with the base 2 through two bearings 3;
[0032] The middle spacer 4 is arranged between the two bearings 3, and the two sides of the middle spacer 4 are respectively in contact with the outer rings of the two bearings 3, the outer ring of the right bearing 3 is in contact with the shaft shoulder on the base 2, and the right The inner ring of the side bearing 3 is in...
