前言AISn20Cu—钢轴瓦(以下简称钢背铝瓦)在东风内燃机车10L207E 柴油机上推广运用已十多年。试验初,曾实测过几台车的曲轴和轴瓦的磨损值,对其可靠性作过初步估价。但限于当时条件,统计数据不足,尚难以对其运用效果作出评价。为此,我们自1982年以来,先后在峨眉、金城江、水城、昆明、加格达奇和郑南等六个运用条件差别较大的内燃机车架修段,对42台东风_1
Foreword AISn20Cu-steel bearing (hereinafter referred to as the steel back aluminum tile) in the Dongfeng diesel locomotive 10L207E diesel engine to promote the use of more than 10 years. At the beginning of the experiment, the wear value of crankshaft and bearing bush of several vehicles was measured and the reliability was preliminarily evaluated. However, due to the conditions at that time, insufficient statistical data, it is still difficult to evaluate the effectiveness of its use. To this end, since 1982, we have successively repaired six diesel locomotive frames with relatively different operating conditions in Emei, Jincheng River, Watertown, Kunming, Jiagedaqi and Zhengnan. Forty-two Dongfeng 1
