摘要

齿轮渗碳淬火变形指标有很多，但最终都将体现在齿面实际磨削量上。通过理论分析并结合长期生产实践发现，齿顶圆胀缩对磨削量影响最大，螺旋角变化和轮缘周向翘曲影响次之，其他因素影响相对较小。给出了依据齿轮直径胀缩量和其他参数计算齿面最大、最小磨削量的经验公式。在设计、工艺编制及热后质检时利用这些公式，可更加合理地确定图纸有效硬化层深度（Case-Hardened Depth，CHD）、滚齿时齿面预留磨削量和渗碳淬火时的目标CHD；渗碳淬火后还可以按照经验公式提前计算预估最大磨削量、最小磨削量和磨后齿面实际CHD，为后续生产提供指导。

Abstract

There are many kinds of distortion of carburizing and quenching gears

but they will be reflected in the grinding amount of gear flanks. Through theoretical analysis and long-term production practice

it is found that the change of tip diameter has the greatest influence on the grinding amount

the change of the helix angle and the circumferential warpage of gear rims takes the second place

and other factors have relatively little influence. The empirical formulas for calculating the maximum and minimum grinding amount of the tooth flank are given

according to the change of the tip diameter and other parameters. These formulas can be used to determine the case-hardened depth (CHD) in drawings

the reserved grinding amount of gear flanks during gear hobbing

and the target CHD during carburizing and quenching. After carburizing and quenching

the maximum and minimum grinding amount and the actual CHD can be calculated and predicted according to these formulas

so as to provide guidance for subsequent production.
