一台使用了4年多的泰山-12型拖拉机,前一阶段仅半年时间就折断了4根半轴。前三次由机手自己拆换了半轴,第四次终于请人来修理。第四次,在拆下断了的右半轴时,发现拖拉机里端花键处有一个铁圈套在半轴上被同时取下。于是修理者便断定是差速器盖上的轴承座损坏了,所以新半轴使用不久半轴就会被撬断。机手由于不了解差速器的构造,把差速器盖上损坏的轴承座当成了套在半轴上的垫圈,所以前三次在装新轴时又把它套在上面,并未想到要更换新的差
A Taishan-12 tractor, which had been used for more than four years, had broken four semi-axles in just six months in the previous phase. The first three times by the hands of their own semi-shaft, the fourth person finally asked to repair. Fourth, when the broken right half shaft was disassembled, it was found that an iron snare was removed from the half shaft at the trailing spline end of the tractor. So the repairer will determine the differential cover is damaged on the bearing, so the use of the new axle will soon be used semi-pry off. Because the hand did not understand the differential structure, the differential cover damaged bearing as a sleeve set in the half-shaft washers, so the first three times in the new shaft installed again put it on the top, did not expect to Change new bad
