挡圈的选型指南:
因为挡圈一般用的是弹簧钢65Mn这种材料,经过热处理其性能综合力学性能优于碳钢,但有过热敏感性和回火脆性。用作小尺寸各种扁、圆弹簧、座垫弹簧、弹簧发条,也可制作弹簧环、气门簧、离合器簧片、刹车弹簧及冷拔钢丝冷卷螺旋弹簧。 轴旋转的时候卡簧也是随着转动的并且卡的很紧,只要卡簧不会断裂,一般不会出现脱落的现象。
挡圈的维护保养:
孔用挡圈安装在圆孔内,用作固定零部件的轴向运动,这类挡圈的外径比装配圆孔直径径稍大。安装时须用卡簧钳,将钳嘴插入挡圈的钳孔中,夹紧挡圈,才能放入预先加工好的圆孔内槽。它多用于轴承孔,靠孔的外侧位置,“挡住”轴承外圈用的。止动环是具有恒定截面的单口环,装在环形沟里,使滚动轴承在外壳内或轴上进行轴向定位。
