从内燃机车的运用情况来看,当前一个重要的课题是提高机车的可靠性和耐久性。显然,这和提高柴油机的经济性一样,将取得很大的经济效益。就机车转向架而言,运用实践表明,可靠性问题不是太大,主要是耐久性问题。其中,轮缘的过早磨耗、牵引齿轮的剧烈磨损或裂纹、轮箍踏面的严重剥离等,在运用中时有发生,有时不仅限制了机车转向架使用 From the use of diesel locomotive point of view, the current important task is to improve the reliability and durability of the locomotive. Obviously, this will bring great economic benefits as much as improving the economy of diesel engines. As far as locomotive bogies are concerned, the practice shows that the reliability problem is not too large, mainly the issue of durability. Among them, the premature wear of the rim, the traction gear of the severe wear and tear, serious tire tread stripping, etc. Occasionally occurred during use, and sometimes not only limited the use of locomotive bogies
