擋圈的選型指南:
因為擋圈一般用的是彈簧鋼65Mn這種材料,經(jīng)過熱處理其性能綜合力學(xué)性能優(yōu)于碳鋼,但有過熱敏感性和回火脆性。用作小尺寸各種扁、圓彈簧、座墊彈簧、彈簧發(fā)條,也可制作彈簧環(huán)、氣門簧、離合器簧片、剎車彈簧及冷拔鋼絲冷卷螺旋彈簧。 軸旋轉(zhuǎn)的時候卡簧也是隨著轉(zhuǎn)動的并且卡的很緊,只要卡簧不會斷裂,一般不會出現(xiàn)脫落的現(xiàn)象。
擋圈的維護保養(yǎng):
孔用擋圈安裝在圓孔內(nèi),用作固定零部件的軸向運動,這類擋圈的外徑比裝配圓孔直徑徑稍大。安裝時須用卡簧鉗,將鉗嘴插入擋圈的鉗孔中,夾緊擋圈,才能放入預(yù)先加工好的圓孔內(nèi)槽。它多用于軸承孔,靠孔的外側(cè)位置,“擋住”軸承外圈用的。止動環(huán)是具有恒定截面的單口環(huán),裝在環(huán)形溝里,使?jié)L動軸承在外殼內(nèi)或軸上進行軸向定位。
