Description
Technical field
The present invention relates to a kind of radial support and axial pretightening structure, more particularly to a kind of installation bearing electric machine rotor are dynamic flat
Weighed the radial support and axial pretightening structure measured, and radial support and axial pretightening are carried out to having installed bearing electric machine rotor.
Background technology
Motor is important production and daily necessities, rotor therein are the important process parts of motor.Rotor is producing
During, due to designing that unreasonable, material is uneven and the reason such as process and assemble error, be inevitably present it is initial not
Aequum.Rotor with excessive amount of unbalance can produce vibration and noise, gently then make motor in the operation process of motor
Can degenerate, it is heavy then cause damage and accident, so must to rotor progress dynamic balance treatment, maintain its amount of unbalance qualified
In the range of.
Rotor dynamic balancing corrective can be divided into two major classes, i.e., amendment dynamic balancing machine and full automatic balance amendment are set by hand
It is standby.Amendment balancing machine cost is low by hand, but equilibrium process relies on worker's experience, and Equilibrium Equivalent Concentration is difficult to be guaranteed.With this
