Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a motor with an automatic bearing lubrication function. Background Art

[0002] Motor bearings, also known as electric motor bearings or motor bearings, are a special type of bearing used specifically for electric motors or motors. Its main function is to support mechanical rotating bodies to reduce the mechanical load friction coefficient of the equipment during transmission. Motor bearings use smooth metal balls or rollers and lubricated inner and outer ring metal surfaces to reduce friction. These balls or rollers carry the load and support the motor shaft, allowing the motor to rotate smoothly. There are four types of bearings commonly used in motors, namely rolling bearings, sliding bearings, spherical bearings and oil-containing bearings. Among them, rolling bearings are the most common type of motor bearings, which are composed of bearings with rolling elements. Sliding bearings refer to bearings without rolling elements, that is, bearings that slide. In addition, motor bearings can be classified in many ways according to the load direction, type of rolling element, whether it can be self-aligned, number of rolling element rows, whether the components can be separated, and other standards. The selection and design of motor bearings are crucial to the performance and life of the motor. Suitable bearings can reduce energy consumption, reduce noise and vibration, and improve the reliability and durability of the motor. The application range of motor bearings is very wide, involving small and medium-sized motors, large and medium-sized motors, variable frequency motors and various industrial machinery and equipment.
