Embodiment 1

[0045] This embodiment provides a low damping rotating device, such as figure 1As shown, the low-damping rotating device includes a rotating part and a fixed part, wherein: the rotating part includes a vertically placed rotating shaft 7 and a magnet module fixed on the rotating shaft 7; The first permanent magnet 2 and the first jewel bearing 5 above the rotating shaft 7, and the second jewel bearing 11 below the rotating shaft 7; the rotating shaft 7 is covered by the first jewel bearing 5 and the first jewel bearing 5. The two jewel bearings 11 are clamped and rotated; the magnet module and the first permanent magnet 2 generate an attractive force, and by adjusting the vertical position of the first permanent magnet 2, the rotation shaft 7 is adjusted to the second jewel. The pressure of the bearing 11. Among them: the magnet module on the rotating shaft 7 and the first permanent magnet 2 arranged on the upper fixed part generate an attractive force, and by precisely adjust...

Embodiment 2

[0055] This embodiment provides an operation method of the low-damping rotating device as described in the previous embodiment, including: installing the target 10 according to actual needs, fastening the screw knob with the target clamping device 8, and adjusting the matching smooth block 9 The position of the target clamping device 8 balances the weight distribution. After the rotating shaft 7 is installed between the first jewel bearing 5 and the second jewel bearing 11, by adjusting the upper and lower positions of the first permanent magnet 2, the attractive force of the first permanent magnet 2 to the rotating shaft 7 can better offset the rotating part. Own gravity reduces rotational damping.

[0056] Further, the low-damping rotating device is placed in an atmospheric environment. When the rotating part is in a static state, the airflow ejected from the air injection device blows to the rotating part, and the torque generated by the airflow makes the rotating part Sta...

Description

technical field [0001] The invention relates to the technical field of precision mechanics, in particular to a low-damping rotating device and an operating method thereof. Background technique [0002] Low-damping rotating devices, such as bearings and superconducting magnetic levitation, are widely used in precision machinery, aerospace and other fields. Their development plays an important role in reducing energy consumption, high-precision processing, and improving the performance of testing equipment. [0003] Commonly used low-damping rotating devices are usually realized by using contact-type traditional rotating bearings or non-contact-type such as superconducting magnetic levitation rotating mechanisms. Traditional bearings achieve the purpose of reducing energy loss by reducing the relative frictional resistance between the rotating object and the fixed body through the rotation or revolution of the rolling elements. When using this type of bearing, it is difficult...
