轴承的寿命是与保养和维护有着非常重要的关系,因为它关系到TIMKEN轴承寿命的长短,工作效率的高低。维护保养好所使用的TIMKEN轴承,会带来不少的受益,比如说可以带来高的生产效率,生产出质量精密更高的产品,几次的维护可以延长寿命为你节省一次重新采购的费用。
Bearing life is the relationship with the care and maintenance is very important, because it pertains to the length of the TIMKEN bearing life, productivity high and low. Good maintenance the TIMKEN bearings, will bring a lot of benefits, for example, can bring about high production efficiency, producing more high quality precision products, maintenance can extend the life of the times once again purchase cost savings for you.
1 调整垫片法:
在轴承端盖与轴承座端面之间填放一组软材料(软钢片或弹性纸)垫片;调整时,先不放垫片装上TIMKEN轴承端盖,一面均匀地拧紧轴承端盖上的螺钉,一面用手转动轴,直到轴承滚动体与外圈接触而轴内部没有间隙为止;这时测量轴承端盖与轴承座端面之间的间隙,再加上TIMKEN轴承在正常工作时所需要的轴向间隙;这就是所需填放垫片的总厚度,然后把准备好的垫片填放在轴承端盖与轴承座端面之间,最后拧紧螺钉。
Adjustment gasket 1 method:
In bearing end cover and bearing block end surface Zhijian filled placed a group soft material (soft steel tablets or elastic paper) gasket; adjustment Shi, first does not placed gasket loaded Shang TIMKEN bearing end cover, side uniform to screwed tight bearing end cover Shang of screws, side with hand turning axis, until bearing scroll body and outer ring contact and axis internal no gap weizhi; then measurement bearing end cover and bearing block end surface Zhijian of gap, again plus TIMKEN bearing in normal work Shi by needs of axis to gap; this is by needed filled placed gasket of total thickness, And gasket ready to fill in between the bearing end cover and housing, and finally tighten the screws.
2 调整螺栓法:
把压圈压在轴承的外圈上,用调整螺栓加压;在加压调整之前,首先要测量调整螺栓的螺距,然后把调整螺栓慢慢旋紧,直到轴承内部没有间隙为止,然后算出调整螺栓相应的旋转角。例如螺距为1.5mm,TIMKEN轴承正常运转所需要的间隙,那么调整螺栓所需要旋转角为3600×0.15/l.5=360;这时把调整螺栓反转360,TIMKEN轴承就获得0.5mm的轴向间隙,然后用止动垫片加以固定即可。
2 adjustment bolt method:
Circle pressure pressure on the bearing outer ring, by adjusting bolts pressure; pressure before adjusting, first measure the pitch adjustment bolt, and then slowly tighten the adjustment bolt, until such time as bearing no gap, and then calculate the adjustment bolt corresponding rotation angle. 1.5mm,TIMKEN pitch for example needed for the normal functioning of the bearing gap, then the required rotation angle adjustment bolt 3600x0.15/l.5=360 when reverse 360,TIMKEN adjustment bolt axial clearance of the bearing on access to 0.5mm, and then snap the gasket to be fixed.
采用润滑脂润滑的流动轴承在运行1500小时后应更换润滑脂,加注的油量要适量,因为润滑脂太多或太少都会引起TIMKEN轴承发热,加油量一般掌握在轴承室容积的1/2~2/3为宜。

Flow of grease-lubricated bearings running grease should be replaced after 1500 hours, filling quantity of oil to be just the right amount, because grease TIMKEN bearings caused by too much or too little heat, fuel generally lies in 1/2~2/3 of bearing Chamber volume.
