1.绪言在热处理的产品零件中,齿轮占很大的比例,而且其热处理要求比其它工件需要更高的技术.但是,要做到对齿轮正确地进行热处理,单靠热处理方面的努力是不够的,与加工制造和设计也有关.为此,本文把有关的经验和改进的实例加以论述,以利于今后热处理工作的改进.2.齿轮的形状和热处理齿轮的形状有千差万别,在这里仅对齿轮各部分中共同的几种主要因素进行探讨.2.1 齿宽一般认为齿宽为模数的7～8倍或最多10倍为宜.其道理是由于即使加大齿宽,也由于加工误差、装配累积误差或负荷条件不同,很

INTRODUCTION Gears make up a large proportion of heat treated product parts and their heat treatment requires higher technology than other workpieces However, in order to properly heat treat the gears, the heat treatment alone is insufficient , And manufacturing and design are also related.To this end, this article will be related to the experience and improved examples to be discussed in order to facilitate the improvement of the future heat treatment .2 gear shape and heat treatment gears vary in shape, only here Gear parts in several common main factors to be explored.2.1 tooth width is generally considered tooth width of 7 to 8 times the modulus or up to 10 times its reason is that even if the increase in tooth width, but also due to processing errors, Assembly cumulative error or load conditions are different, very
