Tapered roller bearing application range

Post by nfhyjs on Thu Sep 18, 2014 3:43 am

Tapered roller bearing used in listening learning error is a very simple method, with examples to verify the electronic stethoscope, feel abnormal sound experience in using a detail statement. Bearing in good condition, a deep voice WuWu subsidiarity sharp cone roller bearing, ZhiZhi bubble Tony Tony and other errors, usually refers to sound bearing in harsh conditions.
1, tile surface corrosion: spectrum analysis found that non-ferrous metal element iron concentration anomaly spectral components appear many nonferrous metals microns particles wear; Linoleic acid medal of the knights of the moisture.
2, cervical surface drag: iron spectrum of abrasive cutting system in iron oxide particles, or black metal surface oxidation color.Oil-free bearings use process problems of elimination method
3, cervical surface corrosion: spectrum analysis found that iron concentration is unusual, iron spectrum of many glands, the oil moisture Alexander medal of micron particles or acid.
4, the surface energy spectrum index are: iron pulling cutting grinding grain, powder non-ferrous metal parts.
5, tile back wear: spectrum analysis found that iron concentration is unusual, ferrographic wear a lot of iron composition of micron particles, oil water and acid.
In liquid lubrication condition, the sliding surface is lubricant, rather than individual in direct contact, also can greatly reduce the friction loss and wear of surface oil film also has a certain vibration absorbing ability
May cause acute ZhiZhi noise does not conform to the lubrication. Bearing clearance does not match can also lead to sound metal. Tapered roller bearing vibration can cause is orbit, smooth, loud sounds, for scars may change depends on the bearing rotating speed position noise noise. Found to have little noise expression may violate per unit volume, tapered roller bearings, the sound sometimes when the damaged surface rolling out of date, if there is pollution caused by bearing was badly damaged and bubble tons for irregular and bearing noise will be enormous.
Through bearing damage may want to check the hearing, but feelings, should be replaced immediately bearing can not at this time. So, better methods, such as electronics, position control taper roller bearings bearing early termination rash.
