Embodiment Construction

[0043] Such as Figure 1 to Figure 6 As shown, a method for adjusting the assembly gap between the magnetic bearing, the auxiliary bearing and the rotor comprises the following steps:

[0044] S1 Prepare the following parts, such as figure 1 shown

[0045] Magnetic bearing 11, rotor 1, thrust plate 14, sensor measuring body 10, displacement sensor 9, auxiliary bearing 6, protective cover 2, spring lamination 5, bearing housing 7, left adjustment block 4, right adjustment block 8; The bearing 11 is provided with a left side coil 12 and a right side coil 13;

[0046] S2 Gap adjustment between magnetic bearing 11 and rotor 1, such as figure 2 shown

[0047] S21 install the thrust plate 14 and the sensor measuring body 10 on the stepped shaft of the rotor 1, the sensor measuring body 10 is located on the left side of the thrust plate 14, the thrust plate 14 and the sensor measuring body 10 move axially synchronously with the rotor 1, and the magnetic bearing 11 Sleeved on th...

Abstract

The invention discloses a method for adjusting the assembling gap between a magnetic bearing, an auxiliary bearing and a rotor, comprising the following steps: S1 preparing the following parts: magnetic bearing, rotor, thrust plate, sensor measuring body, displacement sensor, auxiliary bearing, protective cover, Spring laminations, bearing housings, left adjustment block, and right adjustment block; left and right coils are installed in the magnetic bearing; S2 magnetic bearing and rotor clearance adjustment, so that the thrust plate and the left coil and right side of the magnetic bearing The clearance C and D of the coil are equal; the clearance between the S3 auxiliary bearing and the rotor is adjusted so that the axial clearance value E on the right side of the auxiliary bearing is equal to the axial clearance value F on the left side of the auxiliary bearing, and the values ​​​​of E and F are less than C , the value of D, through this adjustment method, the magnetic bearing and auxiliary bearing can be in a proper position in the rotor system, which can not only protect the magnetic bearing more effectively, but also facilitate the design of the magnetic bearing controller, and realize the auxiliary bearing to the magnetic bearing. Protect.

Description

technical field [0001] The invention relates to the technical field of bearing and rotor assembly, in particular to a method for adjusting the assembly gap between a magnetic bearing, an auxiliary bearing and a rotor. Background technique [0002] With the development of modern industry, the requirements for the speed and precision of rotating machinery are getting higher and higher. For other rotating machinery in special fields working in extremely high or low temperature environments, in addition to being able to withstand harsh environmental tests, the controllability, safety and reliability of the support are often the first considerations. According to the current research, the magnetic suspension bearing is the first to be recommended. The magnetic suspension bearing is a high-performance bearing that uses magnetic field force to suspend the rotor in the air without mechanical friction. Because the magnetic suspension bearing has It has the advantages of no friction,...
