Method for working ultrafine conical rolling bearing

Abstract

A superfinishing method for a tapered roller bearing, comprising the steps of: rotating the outer ring of the tapered roller bearing around the central axis of the tapered roller bearing; inserting a right-angled superfinishing stone from the front of the outer ring; and The front end face of the superfinishing stone is in sliding contact with the surface of the conical race formed on the inner peripheral surface of the outer ring, and thereby superfinishes the race surface. The super-finishing stones are inclined to the outside in front of the outer ring corresponding to the vertical line of the race surface.

Description

technical field [0001] The present invention relates to an apparatus and method for bringing the surface of a race in sliding contact with a superfinishing stone and superfinishing the race from the superfinishing stone, the race being made on the outer ring of a tapered roller bearing In particular, it relates to an improved technique capable of avoiding interference between the superfinishing stone and the bezel. Background technique [0002] In the prior art, the surface of the raceway of the tapered roller bearing is super-finished, for example, by using such as Figure 7 The superfinishing device 1 shown. The superfinishing device 1 comprises a back plate 5, a pair of push rollers 7 (only one of which is shown), a pair of shoes 9 (only the lower part is shown), a superfinishing stone holder 13, a superfinishing Finishing stone clamping bolt 17, a pressurizing cylinder 21 and a swing table 23. The back panel 5 drives the outer ring 3 to rotate. T...

AI Technical Summary

Problems solved by technology

Therefore, when superfinishing the outer ring with a smaller hole diameter, it is necessary to use a shorter superfinishing stone that can be inserted into the inner circumference of the outer ring, thus increasing the frequency of replacement of the superfinishing stone, resulting in efficiency reduction

In addition, superfinishing stones require a useless clamping portion, which leads to increased waste of superfinishing stones

In addition, not only does the above-mentioned interference between the rear end of the superfinishing stone and the non-machined race surface of the outer ring make it impossible to use long superfinishing stones, but it also prevents the use of an automatic superfinishing stone feeding mechanism, hindering The automatic superfinishing stone feeding mechanism automatically feeds the superfinishing stone according to the consumption of the superfinishing stone
