Method and structure for glue injection and holding when assembling bearing for motor

Abstract

The invention provides a method for glue-injection and solidification during the assembly of the bearing of a motor, comprising the steps as follows: two to four glue injection gaps (103) are arranged with equal intervals at the internal side of the end cover of the motor with a clearance fit bearing chamber (101) and at the upper edge of the ring wall of the bearing chamber (101); the motor end cover which is assembled in the bearing (102) is assembled on the motor (106), and all assembly and correction procedures are completed; gluewater (105) is dripped through all glue injection gaps (103) at the circumferential edge of the bearing chamber by each blowhole on the end cover; after the gluewater in the glue injection gaps (103) is completed infiltrated into the clearance (104) between the bearing chamber and the bearing external ring, all the extra gluewater remains in the glue injection gaps and is solidified. Compared with the prior art, the method has the technical effects that: due to the liquidity of the gluewater, the gluewater can be excellently ensured to be uniformly shared in the clearance between the bearing chamber and the bearing external ring, the solidification between the bearing and the bearing chamber is achieved, the damage of gluewater infiltrated inside the bearing to the bearing is avoided, simultaneously, the degree of adaptability of the motor and the bearing is improved, and the noise and vibration of the motor are greatly reduced.

Description

technical field [0001] The invention relates to a motor casing and a supporting object, in particular to a bearing supporting device, in particular to a method and a structure for injecting glue and holding the motor when assembling the bearing. Background technique [0002] In the prior art, when the motor adopts the bearing outer ring clearance fit method to assemble the rolling bearing, the outer ring of the bearing is first coated with glue and put into the end cover, and then the motor is assembled. This method has two disadvantages: one is that the amount of glue is not easy to control when applying glue, too much or too little, which will cause the bearing to loosen after assembly or the glue will soak into the bearing and damage the bearing; second, the motor will be damaged after assembly. Due to the comprehensive influence of bearing concentricity and other assembly problems, the motor may not meet the requirements in terms of sound and vibration. Contents of the...
