Abstract

The invention discloses a mounting structure applying pretightening force on a magnetic suspension motor protection bearing; a protection bearing inner race seat is sleeved on a thrust disc, and a clearance fit is formed between the two; a pressure plate is fixed on a motor base; a bearing mounting chamber is formed between the pressure plate and the protection bearing inner race seat; two protection bearings are respectively sleeved on the protection bearing inner race seat in an upper layer and a lower layer; the inner race of the upper protection bearing abuts against the protection bearinginner race seat; the outer race abuts against the pressure plate; a press cover is fixed on the pressure plate; one end of the press cover abuts against the outer race of the lower protection bearing; a stop block is threaded on the protection bearing inner race seat; when the stop block presses on the inner race of the lower protection bearing, an shaft end stop plate is sleeved on the rotor soas to axially fix the protection bearing inner race seat on the rotor; a shaft end locking nut is threaded on the rotor, and abuts against the shaft end stop plate.

Description

Technical field:

[0001] The invention relates to a mounting structure for protecting a bearing of a magnetic levitation motor and adding pretightening force. Background technique:

[0002] The protective bearing of the magnetic levitation motor is an important component inside the motor. It plays the role of protecting the rotor of the motor. In the actual application process, after the rotor is unstable, it hits the protective bearing, and the rotor is seriously damaged due to the serious deformation of the protective bearing. Therefore, there are It is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content:

[0003] The present invention provides an installation structure for protecting bearings of magnetic levitation motors and adding pretightening force in order to solve the above-mentioned problems in the prior art.

[0004] The technical solutions adopted in the present invention include: an installation structure for magnet...
