Problems solved by technology

[0003] Motor (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. The service life of the motor is greatly affected by the service life of the bearing. When the bearing is damaged, if it is not Timely replacement will greatly reduce the service life of the motor, and the maintenance of the motor is mostly time-consuming and laborious, which

Example Embodiment

[0021] use Figure 1-Figure 4 The structure of the bearing of the present invention is explained as follows.

[0022] Such as figure 1 As shown, the method for improving the service life of a motor according to the present invention includes the following steps:

[0023] S1, the motor shaft is connected to the motor housing through a sealed bearing;

[0024] S2, on the basis of S1, an axial through hole is coaxially opened on the motor shaft along the axial direction, a radial through hole communicating with the axial through hole is opened along the radial direction of the motor shaft, the axial through hole and the radial through hole The hole can lead out the heat inside the motor;

[0025] The sealed bearing used in the above method includes an inner ring 1, an outer ring 2, balls 3, and a sealing end cover 4. The outer ring 2 is provided with annular grooves 11 on both ends, and the inner wall of the outer ring 2 is A sliding groove 21 is provided to the outer ring 2 and the sl...

Abstract

The invention belongs to the technical field of motors, and particularly relates to a method for prolonging the service life of a motor. A sealing bearing adopted in the method comprises an inner ring, an outer ring, a ball and sealing end covers; annular grooves are formed in the two end surfaces of the outer ring and the inner ring respectively, and the ball is located between the inner ring andthe outer ring; two annular protrusions are coaxially arranged on one end planes of the sealing end covers, and the sealing end covers are mounted on the left and right end planes of the inner ring and the outer ring through the annular protrusions and the annular grooves of the inner ring and the outer ring; a contact inner ring and a contact outer ring are arranged at the positions, in contactwith the ball, of the inner ring and the outer ring respectively, and limiting rings are arranged on the inner ring and the outer ring respectively; and an annular boss is arranged at the part, located between the inner ring and the outer ring, of each sealing end cover; and the part, in contact with the roll, of each annular boss is set to be arc-shaped. By virtue of the sealing bearing adopted in the method, resistance caused by the bearing to the motor can be reduced, so that the using efficiency of the motor is improved.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and specifically relates to a method for improving the service life of electric motors. Background technique [0002] During the use of the bearing, harmful substances such as dust, moisture, and foreign matter can easily invade the interior of the bearing or cause the internal lubricant to leak when the bearing rotates, which greatly reduces the lubrication performance of the bearing and reduces the service life of the bearing. The traditional bearing seal is to install the bearing sealing ring through the sealing groove of the outer ring of the bearing. Because the sealing groove of the bearing outer ring and the bearing sealing ring are not tightly matched, when the user uses the bearing, in some cases, the working environment is poor and the bearing is soaked in liquid. If it is immersed in the place, the grease in the bearing cavity will deteriorate, the lubricating performance will...
