国营灵山农业机械厂在了解该厂仿制的苏式П—5一35M五铧犁及苏联进口的这一型号五铧犁的使用情况时,发现多数的犁都是沟轮轴和地轮轴弯扭变形了。有的变形很大,使自动升降机构失效而起不来犁。沟轮地轮轴的弯扭情况大体如图( 1)所示。弯曲变形的地方,是在(自轮子起的)第一个轴承里部一小段,往外伸中入约150—200公厘不等。扭转变形一般不易看出,其变形线与前进方向相反,即向后扭转,有的还将耕深卡铁卡坏(拼深卡
The state-owned Lingshan Agricultural Machinery Plant found that most of the plows were found to be bent and torsionally deformed by the grooved shaft and the wheel shaft when they were used to understanding the use of the Soviet-type П-5 -35M five-plow imitation plow and the Soviet Union-imported five-plow plow. It’s Some deformation is large, so that the automatic lifting mechanism failed to play plow. Groove wheel shaft to the general situation of bending and torsion shown in Figure (1) below. Bend deformation is in the first bearing (from the wheel) in the first a short stretch out into about 150-200 mm range. Torsion deformation is generally not easy to see, the deformation line and the forward direction is opposite, that is, backward twist, and some will also plow deep card bad card (fight deep card
