架起车体,轴箱从轴箱导框里被卸下时,轴箱易翻转,使轴瓦白合金和轴颈擦伤,油线卷移动,轴油流失,从而给作业造成很大的困难。过去轴箱左右各要一人把持轴箱。现设计本防转器(图1)即在架起车体之前,把本防转器置于轴箱前下方,操纵平衡锤以防止轴箱倒转。 When the car body is erected, the axle box is easy to turn over when it is removed from the guide box of the axle box, which causes the bearing bush white alloy and the journal to be scratched, the oil coil is moved and the axle oil is lost, which causes great difficulties to the homework .
