Motor bearing lubrication structure

Abstract

The invention discloses a motor bearing lubrication structure. The motor comprises a stator, a rotor, an end cover, a motor casing, a motor shaft and a bearing, the stator is connected with the motorcasing, the end cover is connected with the motor casing, the rotor is connected with the motor shaft, the motor shaft is connected with the end cover through the bearing, the end cover and the motorcasing form a closed space, a certain amount of lubricating medium is injected into the closed space, the lubricating medium is employed to achieve lubricating and cooling of the bearing and lubricating and cooling of a rotational seal piece used for the motor shaft, and therefore, the service lives of the bearing and the rotational seal piece used for the motor shaft are prolonged, the internal temperature distribution of the motor can be balanced, and the motor performances can be improved.

Description

technical field [0001] The invention relates to a motor structure, in particular to a lubricating structure for a motor bearing. Background technique [0002] The motor rotor and the end cover are connected by bearings. The bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. However, the bearing In the process of long-term high-speed work, wear and damage will be caused by friction, corrosion, seal damage and other reasons, resulting in reduced rotation accuracy, which will cause a decrease in the overall performance of the motor, and even cause motor failure and accidents in serious cases. The operation of the motor will cause the wear of the rotary seal used for the motor shaft, and the high temperature will cause the aging of the rubber parts, which will cause the internal sealing of the motor to decrease, whic...
