普通型橡胶油封(图1)是机械上广泛采用的旋转轴密封件。它的质量好坏在一定程度上反映了主机质量。通过对一些机械发生渗漏现象的结构进行具体分析,不考虑油封以外的其它因素,就油封本身的影响而言,一是油封的结构及制造质量没有达到应有的设计要求,特别是有些被作为标准件的普通型油封不能满足一般使用工作条件;二是 Ordinary rubber seal (Figure 1) is widely used in machinery rotary shaft seal. Its quality, to some extent, reflects the quality of the host. Through some concrete leakage phenomenon of the structure of a specific analysis, without considering the oil seal other factors, the impact of the oil seal itself, first, the structure of the oil seal and manufacturing quality did not meet the design requirements, in particular, some were As a standard part of the ordinary type of oil seal can not meet the general conditions of use; Second is
