一、锥形摩擦块W1001、Э1004挖掘机逆转机构的锥形摩擦块,由于使用年限不一,锥形鼓的摩擦程度也不一样,对锥形摩擦块的尺寸要求也不同,给维修带来不少困难。我们在修理中,将原石棉制品锥形块用铝体锥面铆合刹车带代替,使用情况良好。改进工艺如下: 1.按图1a尺寸铸铝图并留加工余量; 2.照图1a加工成形,打好锥形块稳钉孔;
1. Conical friction blocks W1001 and Э1004 The conical friction blocks of the reversing mechanism of the excavator, due to the difference in service life, the friction degree of the conical drum is not the same, and the requirements for the size of the conical friction block are also different. Many difficulties. During the repair, we replaced the original asbestos product cone block with aluminum body taper riveted brake belts and used it well. The improvement process is as follows: 1. According to Figure 1a size cast aluminum diagram and leave the machining allowance; 2. According to Figure 1a processing forming, hit the cone block stud hole;
