随着我国工艺装备水平的发展,齿轮行业新购置了大量成型磨齿机,几乎都会遇到磨削烧伤问题,个别厂家甚至数月调试也没有解决这一难题,造成严重的损失。而目前对于磨削烧伤所采取的措施几乎都是消极降低磨削参数,以牺牲效率为代价,增加了很多成本。本文针对两种渗碳淬火齿轮磨齿过程中产生磨削烧伤导致的服役前开裂和服役中开裂失效情况,从齿轮开裂形式和形成原因对齿轮磨齿中的磨削烧伤形式进行了分析并提出改善措施。 With the development of China’s technology and equipment, the gear industry newly purchased a large number of forming grinding machines, almost all will encounter the problem of grinding burns, individual manufacturers or even months of debugging did not solve this problem, resulting in serious losses. At present, almost all the measures taken for grinding burns reduce the grinding parameters negatively, which adds a lot of costs at the expense of efficiency. In this paper, two types of carburizing and quenching gear grinding process caused by grinding burns lead to cracking before service and in service cracking failure, gear cracking forms and causes of gear grinding tooth grinding injuries were analyzed and presented Improvements.
