摘要

针对某薄板齿轮加工过程中易出现变形的问题，分析其产生的主要原因为机械加工后残余应力较大、热处理时热应力与组织应力较大、磨削热影响、磨削工件刚性差、定位面平面度误差大、精加工过程安排不合理以及装夹不稳定等。结合实际加工，提出优化热处理零件结构，减少机加工残余应力影响，减小定位面平面度误差，优化精加工过程，提高装夹稳定性等改进措施。经实例验证，改进后的加工工艺效果良好，保证了零件加工精度，可为类似薄板齿轮零件提供技术借鉴。

Abstract

Aiming at the deformation of thin plate gears

the main reasons are analyzed as follows: large residual stress after machining

large thermal stress and structural stress during heat treatment

effects of grinding heat

poor rigidity of parts during grinding

large flatness error of locating surface

unreasonable arrangement of finishing process and unstable clamping. Combined with the actual processing

several improvement measures are put forward

such as optimizing the structure of heat treated parts

reducing the influence of machining residual stress

reducing the flatness error of locating surface

optimizing the finishing process and improving clamping stability. It is verified that these improvement measures have positive impact and ensure the accuracy of parts

which provides technical reference for similar thin plate gear parts.
