柴油机机体主轴承座在运用中承受着由曲轴传来的复杂的交变载荷,损坏相当严重。据我厂统计,因主轴承座变形或裂纹需进行修理的机体占总修车台数的60～70％。主轴承座损坏后,必然要导致曲轴的严重磨损,缩短柴油机的使用寿命。因此对柴油机机体主轴承座的变形或裂纹应作认真地检查并及时修理。现将我厂对主轴承座的检查情况及所采取的修理方法介绍于下。一、机体主轴承座变形裂纹的一般特征
Diesel engine main bearing in the use of the crankshaft from the complex alternating load, the damage is quite serious. According to my factory statistics, due to the main bearing housing deformation or cracks need to be repaired body accounted for 60-70% of the total number of cars. After the main bearing housing is damaged, the crankshaft will inevitably lead to serious wear and tear, shorten the life of the diesel engine. Therefore, the main body of the diesel engine housing deformation or cracks should be carefully checked and promptly repaired. Now my factory inspection of the main bearing and the repair methods introduced in the next. First, the general characteristics of the body main bearing housing deformation cracks
