建筑机械大都以高速柴油机为动力,当连杆铜套与活塞销的配合间隙超过使用极限后(一般为0.2～0.3mm),必须更换连杆铜套,否则会导致活塞销窜出,并捣坏缸体的大事故。在柴油机修理中,连杆铜套的加工精度及与活塞销的配合间隙,是能否确保机车正常运转的关键工艺之一。一般基层修理单位,大都用手工铰刮来完成上述工艺。这种修理方法不但费工费
Most of construction machinery is powered by high-speed diesel engines. When the clearance between the connecting rod copper sleeve and the piston pin exceeds the limit of use (usually 0.2-0.3mm), the connecting rod copper sleeve must be replaced. Otherwise, the piston pin will be ejected. Accidents of bad cylinders. In the diesel engine repair, the machining accuracy of the connecting rod copper sleeve and the clearance with the piston pin are one of the key technologies to ensure the normal operation of the locomotive. Most of the grassroots repair units generally use manual reaming to complete the above process. This repair method not only costs money
