一、滚动轴承在拖拉机的修理中,常常发现滚动轴承有的因局部磨损而造成报废,如东方红-54(75)拖拉机变速箱二轴后轴承2712K轴承外套,因长期工作而局部出现磨损的印痕,有时可用手感觉到或用眼看出。这是由于齿轮在传递动力时作用于轴承上的侧向力所造成的。轴承的这种局部磨损不仅使径向间隙变大以致报废,同时还会改变大小锥齿轮、变速箱齿轮、变速箱各轴之间良好的相对位置,加速这些零件的损坏。
First, the rolling bearings In the repair of tractors, some of the rolling bearings are often found to be scrapped due to local wear and tear, such as the East Red -54 (75) tractor gearbox bearing 2712K two-axis bearings, due to long-term work and partial wear marks, Sometimes felt by hand or by eyes. This is due to the lateral forces acting on the bearings when the gears transmit power. This partial wear of the bearing not only causes the radial clearance to become larger so as to be discarded, but also changes the relative positions between the bevel gear, the transmission gear, and the transmission shafts to accelerate the damage of these parts.
