Precautions for the use of bearings

漆動軸承是精密部件 位却范使用。使用不当 則送不到璵期的性能。有美軸承的使用注意事項如下：

1、保持軸承及其周国清活,即使是眼晴看不到的小坐埃,也会飴柚承帯来不良影。所以,要保持周国清沽,使坐埃不致侵入軸承。
2小心達慎地使用張烈冲盂会使軸承芹生傍瘍及圧瘍,浮重的情況下,釉承会裂鑵、断裂,往往成事故的原因。
3、使用怡当的操作工具必使用俗当的安装工具避免対軸承造成摂。
4要避免柚承的誘蝕安装軸承肘手上的汗水会尋致生誘,最好戴上手套作巫。

安装

安装是否正硝,亘接影向軸承精度、寿命、性能。因此,没辻及塑装部 対手柚承的安装要充分研究 立按照正碑、科学的作此析准辻行安装作此流程如下:

有在需要安装軸承肘オ打刑軸承包装。一般脂淘滑軸承不需清洗填充淘滑脂。淘滑油涵滑普通也不用清洗但是 伐器用或高速用軸承等要用浩浄的油洗浄 除去余在軸承上的防誘油。除去了防誘利的軸承容易生誘,所以不能放置不嘆。

再者己封入淘滑脂的軸承不清洗直接使用。

軸承的安装方法,因軸承結杓、配合、永件而昇、一般由于多軸承旋 所以内圏需要泣盈配合。國杜孔柚承,多用庄力机入或多用熟装方法。鑵孔的珍合宣接安装在鑵度軸上或同套筒安装。

小型軸承刃使用庄力机圧入的方法。如図9所示 将塾快塾入内圏 用庄力机穏 地庄至 刃止 将外圏塾上塾埃安装内圏,会造成漆道上的圧瘍、圧,要色対禁止。

操作肘,最好事先在配合面上塗油。如用斗鼓打安装 需在内圏上加放塾埃。但操作方法容易尋致軸承揖 仮限用于迅盈量小的情況,不能用于迅盈量大或中小型軸承。

非分禽型軸承如深淘球軸承,内圏、外闍都需要泣盈安装肘 塾快塾上后,用螺杵或油圧将内闍和外闍同肘圧人。如図92所示。

2 大型軸承圧入肘需要根大的力 所以根准圧入。因此 在油中将軸承加熟 使之膨脈 然后装到軸上的熟装方法使用。使用迅神方法 可以不蛤軸承増加不当的力,在短肘同内完成操作。

一般情況下軸承的加熟不度超寸 1 2 0 ^ { \circ } \mathsf { C } 温度太高将造成密封件変形、軸承内外圏回火、油脂池漏等不良情況。

使軸承不宣接接触油槽底部,最好考恵将軸承放在金属図台上或将軸承吊起来;

搭軸承加熟到比所需温度高 2 0 ~ 3 0 ^ { \circ } C 以便操作中不致燈生内圏変凉雅于安装：安装后軸承冷却下来寛度方向也收縮所以要用柚螺母或其他活宣的方法使之察固,以防内圏与軸承当肩之同生鋒際。

3、感位熟装置

除用油熟方法之外,利用申磁感位作用感位加熟装置也汪使用。

感位加熟装置内装励磁図通申后由于申礎感位作用申流侍到被加熟的軸承有軸承自身的抗阻立生熟。因此可以在短肘同内,不用火、 油均勾地加熟。軸承的熟装操作数率高清浩。

圧入内圏

内外圏同肘圧入

装、折較頻繁的合,如圧乳机的観孤用、 鉄道牢鞆軸用等的圜杜漆子軸承,可以利用麦用的感位加熱装畳辻行内圏的安装、折卸。

透犠刈式

Running test

軸承安装結束后,小型机械可以 査項目有因昇物、仍瘍、圧瘍而造成的透不靭、安装不良、安装座加工不良而芹生的旋拙矩寸大等。如无昇常刈可以刑始加載透

大型机械不能手劫旋,无負荷鳥劫后立即芙劫力,辻行性透,桧査有无振劫后再硝定是否辻入劫力透。

功力透鞍,人无負荷低速刑始,慢慢地提 在式西七山 斑昇常度立 即中止透鞋,桧査机械,必要肘卸下軸承桧査

柚承温度一般人外売外表推河可知。利用油 田 古ナ 通常1〜2小肘后 温度穏定。因軸承或安装等的不良,柚承温度会急創升高,出斑昇常高温。 指刊冠 柚承游原河 淘滑方法的迭怪等也是其原因。

柚承的旋鞍音用測声器可以桧測_如有大的金属喋音、昇常声音不却則声音等脱明透鞍昇常。茂生的原因有淘滑不良、軸外売精度不良、軸承的摂昇物的侵入等.

COMMON FAULTS AND COUNTERMEASURES OF BEARING USE

柚承使用常処故障及対策

軸承的折卸

Bearing Remova!

軸承的折卸是在定期桧修、 更換肘辻行的。折卸后如要銚銕使用軸承或巫需桧査軸承的状志其折卸需与安装肘同祥仔鈿辻行。注意不要摂軸承及各琴件．特別是泣盈配合軸承的折卸准度大。根据需要没辻制作折卸工具也十分重要。在折卸肘根据図祇研究折卸方法、晒序、週査軸承的配合糸件硝保不摂柚承。

軸承撮仍的対策

Countermeasure of bearing damage

一般正碑使用軸承,可以込到使用疲芽寿命力止，但有肘也会有多神原因使軸承泣早摂杯迅呰摂杯的原因大多是軸承安装、使用、淘滑上的因泰,或是外部有昇物侵入也可能是対軸、外売的配合及温度影込沢不足,有肘是多稗因泰相互作用的結果。典型軸承摂害及原因対策凡表9_2
