在机务段和在修理工厂里现用的测量技术是不同的,这给评定曲轴——轴承组件的状态带来困难。在工厂条件下,轴承间隙是在曲轴自由地放在主轴承工作瓦上进行测量的,即此时曲轴不受主发电机转子重量的作用,而机体是安置在坚固的梁上,这些梁的支承表面不平度不超过0.05毫米。而在机务段通常所有的测量是在装好了的柴油——发电机组上进行的,那时一 The difference between the locomotive depot and the measurement technology currently used in the repair shop makes it difficult to assess the condition of the crankshaft-bearing assembly. Under factory conditions, the bearing clearance is measured with the crankshaft freely placed on the main bearing work tile, where the crankshaft is not affected by the weight of the main generator rotor and the body is mounted on a solid beam, Support surface roughness of not more than 0.05 mm. In the depot, however, all the usual measurements are made on the installed diesel-generator set, at that moment
