东风型机车的花键轴,是其传动装置的重要零件之一。由于设计上没有考虑到花键的润滑,使花键轴严重磨损现象一直存在。我们知道,柴油机的花键套安装在柴油机泵支承板内部,花键轴通过花键从外部与花键套相联接,如图1所示。不难看出,花键轴的花键与柴油机内部的飞溅机油仅由一法兰相隔。由此,我们设想,只要把内部的飞溅机油引出来,花键润滑这个问题就可以解决了。
Dongfeng locomotive spline shaft, is one of the important parts of its transmission. As the design did not take into account the lubrication of the spline, the spline shaft serious wear and tear there has been. We know that the diesel engine spline sleeve installed in the diesel pump support plate, the spline shaft through the spline from the outside and the spline sleeve is connected, as shown in Figure 1. It is not difficult to see that the spline shaft spline and diesel engine internal splashing oil separated by only a flange. As a result, we envision that as long as the internal splash of oil, spline lubrication problem can be solved.
