Ferromagnetic motor rotor dynamic balance test device

Abstract

A ferromagnetic motor rotor dynamic balance test device relates to the field of motor dynamic balance without a magnetic armature. The ferromagnetic motor rotor dynamic balance test device comprises two movable support plates, two fixed support plates, a main support plate, a pressure plate column, a pressure plate, a ferromagnetic motor rotor, a rotor support tool and two ball bearings; the two fixed support plates are placed symmetrically on both sides of the main support plate; the two movable support plates are fixedly mounted on the outer side walls of the two fixed support plates; the rotor support tool is fixedly installed at the middle of the top end of the main support plate; the ferromagnetic motor rotor passes through the rotor support tool in the axial direction; the pressure plate column is fixedly mounted on the top end of the main support plate, and the pressure plate column is disposed on one side of the rotor support tool; the pressure plate is fixedly mounted on the top end of the pressure plate column and the supporting tool; and the two ball bearings are respectively fixedly mounted on the top ends of the outer side walls of the two movable support plates, and the top ends of the two ball bearings are in contact with the ferromagnetic motor rotor. The ferromagnetic motor rotor dynamic balance test device improves the balance precision of the rotor to a higher level of G0.4, and the dynamic balance performance is consistent.

Description

technical field [0001] The invention relates to the field of dynamic balance of a motor without a magnetic armature, in particular to a dynamic balance test device for a rotor of a strong magnetic motor. Background technique [0002] The vibration caused by motor rotor unbalance is one of the most critical issues in the design and maintenance of generators, and the dynamic unbalanced force it produces has adverse effects on the running state of the motor. The vibration of the motor will generate a lot of noise, accelerate the wear of the motor bearing bush, and seriously affect the performance and safe operation of the motor. In order to reduce or eliminate the vibration of the motor, the dynamic balance of the motor rotor is an indispensable and important link in the production process of the rotor. [0003] In general, before the new rotor of the motor is installed, it will be dynamically balanced by the manufacturer on a specially designed balancing machine. The dynamic...

AI Technical Summary

Problems solved by technology

For the dynamic balance of the strong magnetic rotor of the motor, due to the strong magnetic interference between the strong magnetic rotor and the balance machine bracket, it cannot be directly balanced on the existing ordinary dynamic balancing machine. At present, there is no relevant dynamic balance test device to balance the rotor
