Uniform-section ultra-thin-wall bearing ring turning machining technique

Abstract

The invention relates to a uniform-section ultra-thin-wall bearing ring turning machining technique. The machining technique is completed on a lathe with a commonly-used three-jaw chuck. According to the shape, the size and the intensity of a bearing ring finished product part, the structure, the shape and the size of a turning part are selected. When the ratio of the outer diameter D2 to the inner diameter D2 of the bearing ring part is smaller than or equal to 1.08, the fact that the intensity of a machined part is improved should be considered. According to the uniform-section ultra-thin-wall bearing ring turning machining technique, the structure is reasonable, the technology is applicable, product quality is good, production efficiency is high, and the requirements for machining performance and detecting performance can be met.

Description

technical field [0001] The invention belongs to the technical field of bearing ring technology, and in particular relates to a turning processing method of an equal-section ultra-thin-walled bearing ring. Background technique [0002] For the ultra-thin-walled bearing ring, its small size, light weight, and self-weight will cause deformation, which brings great difficulties to cold and hot processing and testing, and cannot meet the process requirements. [0003] The bearing ring is a ring-shaped part, and the turning process is usually carried out on an ordinary lathe (manual clamping of the workpiece) or a special lathe (pneumatic or hydraulic clamping of the workpiece), and the three-jaw chuck is used to clamp the processed workpiece in the radial direction. When the strength of the bearing ring is sufficient, when the three claws of the lathe fixture are radially clamped, the workpiece to be processed will not be deformed, and the turning quality can meet the processing ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to overcome the deformation defect existing in the turning processing of ultra-thin-walled bearing rings in the existing process, and provide a new-type structure of equal-section ultra-thin-walled bearing ring turning process, the technical problem to be solved In order to solve the deformation problem caused by the clamping of ultra-thin-walled bearing rings, especially the turning process of ultra-thin-walled bearing rings with equal cross-sections, the present invention proposes a turning process for ultra-thin-walled bearing rings with equal cross-sections method, using this method to process, can increase the strength of the bearing ring itself, achieve the purpose of controlling processing deformation and detecting deformation, and will not fail to meet the process requirements due to thin wall and easy deformation
