Oil storage device of high-pressure motor bearing

Abstract

The invention relates to an oil storage device of a high-pressure motor bearing, which is mainly used for improving the protection grade of the high-pressure motor bearing, such as the functions of dust prevention and water prevention. An oil throwing disk is fixed on a rotating shaft of a motor, a V-shaped ring is put in the outer end of an inner ring of a left cover of the bearing to improve the protection grade, and the inner side of a bearing set is fixed through a right cover of the bearing. The oil storage device is characterized in that labyrinth parts are arranged on an inner cover and an outer cover of the bearing, and the left cover of the bearing is internally and additionally provided with the inner ring. The oil storage device has simple, compact and reasonable structure and obvious effect. Under the condition of not changing structure materials, the protection grade of the motor is effectively improved through additionally arranging a labyrinth ring and the labyrinth parts on the inner cover and the outer cover of the bearing and the oil throwing disk. The inner ring is additionally arranged in the left cover of the bearing, and lubricating oil is thrown into an oil storage cavity in the inner ring and the bearing due to the action of centrifugal force, thus the oil storage capacity is greatly enhanced. For part processing, the oil storage device is simple and reasonable and has no influence on mechanical property of workpieces, and for mechanical deviation, because a single radial edge is preserved with an allowance of 1mm and a single axial edge is preserved with an allowance of 2mm, the assembly of the parts have no problems.

Description

technical field [0001] The invention relates to a high-voltage motor bearing oil storage device, which is mainly used for reducing the noise of the high-voltage motor and improving the protection level of the motor. Background technique [0002] With the development of science and technology and the strengthening of human awareness of environmental protection, people pay more and more attention to the pollution of environmental noise. Therefore, the noise level of motors has become an important assessment index of motor performance. The main causes of noise in high-voltage three-phase asynchronous motors are electromagnetic noise and mechanical noise. Among them, the most important mechanical noise is bearing noise. Bearing noise has been listed as three major motor problems along with vibration and temperature rise. Every motor manufacturer will encounter it. Bearing noise is an insurmountable phenomenon. An important reason for bearing noise is the low oil storage capacit...

AI Technical Summary

Problems solved by technology

Its defect is that the oil storage capacity is low, especially the motor with high speed. The motor speed is high and the angular velocity is fast. Due to the centrifugal force, the lubricating oil is thrown into the cavity of the left cover of the bearing. Generally, it is difficult to reach the oil storage capacity. requirements
