摘　　要：有一齿轮箱在空载试车时输入锯齿密封结构出现漏油现象,需要给出简单快捷的解决方案。文中通过校核输入轴承进油量、计算输入密封结构的回油能力和分析密封结构发现,漏油现象是由锯齿密封结构的回油腔造成的,给出了增加T形挡油环和更改密封结构为甩油盘密封两种方案,两种方案均通过了空载试车工厂使用考验。Oil leakage occurred in the input serrated seal structure of a gearbox during no-load test run,the design engineer is required to provide a simple and fast solution.By checking the oil inlet of the input bearing,calculating the oil return capacity of the input seal structure and analyzing the seal structure,this paper finds that the oil leakage is caused by the oil return cavity of the serrated seal structure.Two schemes are given:adding T-shaped oil deflector ring and changing sealing structure to oil slinger seal.Both solutions passed the test of no-load test run and factory use.
