1.注意检查轴颈的锥度、圆度、粗糙度在修理轴瓦的过程中,一定要重视轴颈的锥度、圆度的测量。如果超过了标准值,应将其磨修后再装配轴瓦,否则将会使新装配的轴瓦迅速磨损,发出异响。我们在修理一台50型拖拉机时,做过一次试验,连杆一轴颈圆度0.08毫米,锥度0.06毫米,粗糙度0.80。装上轴瓦使用6小时,就出现了明显的异响。原因是,轴颈出现了较大的圆度和锥度,轴颈与轴瓦的接触面变小。工作时,单位接触面上的压力相应增大,不易
1. Attention to check the journal taper, roundness, roughness In the process of repairing the bearing, must pay attention to journal taper, roundness measurement. If it exceeds the standard value, it should be rebuilt after the bearing pad, otherwise it will make the newly assembled bearing pad worn quickly, abnormal sound. We did a test while repairing a Type 50 tractor with a shaft with a round shaft of 0.08 mm, a taper of 0.06 mm and a roughness of 0.80. Installed on the bush to use 6 hours, appeared obvious abnormal sound. The reason is that the journal has a larger circularity and taper, journal and bush contact surface becomes smaller. Work, the contact pressure on the unit corresponding increase, not easy
