YOT0 1偶合器齿轮传动装置是发电机组电动给水泵配套的主要设备。该传动装置发生过多次齿轮副非正常失效事故。文章从齿轮加工精度、装配精度、修形参数、热处理、安装基础及油系统入手 ,分析失效原因 ,并提出了通过控制人字齿轮轴系和轮齿的精度 ;选取合理的修形参数 ;强化齿轮材料热处理工艺过程 ;保证油质符合要求等可确保偶合器齿轮安全稳定运行。
YOT0 1 coupling gear drive is the generator set of electric feed water pump supporting the main equipment. The transmission has occurred many times gear failure of an accident. In this paper, the causes of failure are analyzed from the aspects of gear machining accuracy, assembly precision, shape modification parameters, heat treatment, installation foundation and oil system. The accuracy of the gear system and the gear teeth is also controlled. Gear material heat treatment process; ensure that the oil meets the requirements to ensure safe and stable operation of the coupling gear.
