Problems solved by technology

[0003] The problems of this method are as follows: First, Vaseline must be used to fix the steel ball in the pocket of the cage to prevent the ball from falling during assembly
However, due to the small space of the bearing, the support surface is narrow, and the vaseline will melt when it meets the outer ring with a higher temperature, which is not enough to adhere to the steel ball, so there is still the phenomenon of ball dropping, which affects the assembly efficiency; Vaseline not only causes waste of Vaseline, which is not conducive to saving the cost of the company, but also is not easy to clean when the finished bearing is cleaned in the later stage, and has to be cleaned repeatedly, which seriously affects the production efficiency of the bearing;
[0004] Secondly, because Vaseline melts when it encounters a high-temperature outer ring, this will cause the outer ring tissue with a higher temperature to shrink suddenly, causing the outer ring that originally needs to be heated to expand to shrink suddenly when it is cold, and the outer ring cannot be enlarged as it should be. The effect of the size, so that the press-fit bearing is affected, and even the steel ball will be scratched under the action of the outer ring that is not fully enlarged, which will affect the vibration and noise of the bearing, and even the service life of the bearing

Abstract

The invention relates to an angular contact ball bearing flexible assembly mold with a fore shaft on an inner ring. The angular contact ball bearing flexible assembly mold comprises a mandrel, a positioning block, springs and a base; the mandrel comprises a guide column, a guide surface is arranged on the upper edge of the guide column, and the lower end of the guide column is fixed on a limiting platform; the upper end surface of the positioning block comprises a positioning platform, and a positioning groove is arranged on an outer ring of the positioning platform; the base is a hollow cylinder with an open upper end, a middle hollow part of the base is an unthreaded hole, and the springs are arranged in the unthreaded hole; the mandrel is arranged on the upper part of the springs; the positioning block sleeves the mandrel; the outer side of the positioning block is connected to the base. The angular contact ball bearing flexible assembly mold is simple in structure and easy to machine; a remarkable effect for assembling an angular contact ball bearing with the fore shaft on the inner ring can be realized; in the assembling process, a step for mixing vaseline is canceled, so that the working procedure is reduced, a great amount of vaseline is saved, the cost is reduced, and the assembling efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of bearing processing and assembly, and in particular relates to an elastic assembly mold of an angular contact ball bearing with a lock on the inner ring. Background technique [0002] It is known that for angular contact ball bearings with locks in the inner ring, the current usual method of assembly is: first heat the outer ring on a heating plate, and install the steel balls coated with Vaseline while waiting for the temperature of the outer ring to rise. Put it into the pocket of the cage, remove the heated outer ring, put it on the outside of the cage with steel balls, and finally put it into the inner ring. [0003] The problems of this method are as follows: First, Vaseline must be used to fix the steel ball in the pocket of the cage to prevent the ball from falling during assembly. However, due to the small space of the bearing, the support surface is narrow, and the vaseline will melt when it meet...
