解决红旗-100及上海-120推土机驱动轮处的漏油问题比较麻烦,即使当时不漏,机器运转一段时间便发现两端同时都漏。修理时,按原厂图纸和工艺要求装配,即驱动轮外端面与轮毂花键端面之K值(见《工程机械》1983年10期)在8_(1.0)~(1.5)mm范围内,但仍未能解决漏油现象。经拆下检查,油封压板的平整度、密封性以及自紧油封弹簧的弹性均很好,油封压板内软木
Solving the problem of oil leakage at the drive wheels of the Hongqi-100 and Shanghai-120 bulldozers was troublesome. Even if it did not leak at that time, the machine was running for a period of time and it was found that both ends were leaking at the same time. During repair, the K value of the outer surface of the drive wheel and the spline end surface of the hub is assembled according to the original drawings and process requirements (see “Construction Machinery” 1983 10) within the range of 8_(1.0)~(1.5)mm, but Still unable to solve the oil spill. After removal of the inspection, the flatness and tightness of the oil seal pressure plate and the elasticity of the self-tightening oil seal spring are very good.
