Abstract

The invention discloses a bearing damping device and a motor, which are used for solving the problems that the stability of a rotor is influenced by large vibration easily generated during long-time high-rotating-speed operation of a rotor of the motor, and the lubrication failure is easily caused by over-high temperature of a bearing. The bearing damping device comprises a bearing mounting body, a bearing and an elastic pipe, wherein the bearing mounting body is provided with a bearing chamber; the outer ring of the bearing is embedded into the bearing chamber; and the elastic pipe is arranged between the outer ring of the bearing and the bearing chamber in a surrounding mode, a fluid inlet and a fluid outlet are formed in the elastic pipe, the fluid inlet is used for introducing fluid into the elastic pipe, and the fluid outlet is used for discharging the fluid in the elastic pipe. The elastic pipe can absorb heat and vibration of the bearing, and stable operation of the rotor is kept.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a bearing vibration damping device and a motor. Background technique [0002] In a motor supported by bearings, the stability of the high-speed operation of the rotor is greatly affected by the vibration state of the bearings, and the high-speed operation of the bearings for a long time is also prone to high temperature problems. In the motor ball bearing support system, the bearing vibration is directly transmitted to the motor through the bearing seat, resulting in increased mechanical noise and affecting the stability and service life of the rotor. Contents of the invention [0003] In view of this, the present invention discloses a bearing vibration damping device and a motor, which are used to solve the problem that the motor rotor easily generates large vibrations during long-term high-speed operation and affects the stability of the rotor, and at the same time, the temper...
