东方红—54/75推土机为林区主要筑路、养路机械之一。其后轴弯曲为生产中常见故障。据调查,一根新换的后轴,机车平均作业100个班次左右,即可发现有程度不同的弯曲。后轴弯曲多发生在两侧悬臂根部,即后轴内轴承颈里侧。后轴一旦弯曲,最终减速器大齿轮的位置便发生前移和歪斜,破坏了大小齿轮的正常啮合,致使发生各种故障,造成经济上的损失和影响正常生产。下面就后轴弯曲的原因及其预防和改进
Dongfanghong-54/75 bulldozers for the main roads in the forest, road maintenance machinery. The shaft bending is a common failure in production. According to the survey, a new replacement for the rear axle, locomotive average operation about 100 flights, you can find a different degree of bending. Bending more occurred in the rear axle cantilever roots on both sides, namely the rear axle bearing neck inside. Once the rear axle is bent, the position of the final gear reducer is shifted and skewed, destroying the normal meshing of the large and small gears, resulting in various malfunctions, resulting in economic losses and affecting normal production. The following reasons for the rear axle bending and its prevention and improvement
