To keep the special requirements of frame materials
1) in must have corrosion resistance occasions, the cage don t need extra high hardness, it can be austenitic stainless steel, and 0 cr18ni9 steel use most;thin wall bearings
2) in high temperature occasion, also use have enough of high temperature strength of austenite stainless steel;
3) when special needs to improve cage strength, can use mild steel plate for carbonitriding surface treatment;
4) in need of self lubricating conditions, can use graphite steel cage, or can reservoir porous materials manufacturing cage;
5) in the magnetic field work, sometimes require material without interfering with external magnetic field, and is not subject to the influence of the external magnetic field.
Bearing temperature, can generally be according to bearing external temperature speculation. But using oil hole direct measurement of the temperature of bearing ring more accurate. Bearing temperature, from the operation began to gradually raised, usually 1 ~ 2 hours after the temperature stability. If the bearing installation is bad, the temperature will rise sharply, abnormal high temperature. I ts reason such as lubricant too much, bearing clearance is too small, installation and undesirable, seal friction too. High speed rotating occasions, bearing structure, the choice of the ways of lubrication error to wait also is the reason.precision ball bearing
The rotation of the bearing stethoscope and inspection, a strong metal noise, different sound, such as irregular sound that anomaly. The reasons are as bad lubrication, shaft or bearing accuracy bad, bearing damage, foreign bodies, intrusion etc.
1, tile surface corrosion: spectrum analysis found that non-ferrous metal element concentration anomaly; Iron spectrum appeared many non-ferrous metal components of submicron level wear particles, Lubricating oil moisture exceeds bid, acid value exceeds bid.big ball bearing
2, journal surface strain: iron spectrum of iron series c utting grinding grain or black oxide particles, metal surface existing heat tint.
3, journal surface corrosion: spectrum analysis found that iron concentration anomaly, iron spectrum, there are many iron components of submicron grain, oil water overweight or acid value exceeds bid.
4, surface strain: iron spectrum volation of cutting abrasive, abrasive grain composition for nonferrous metals.
5, tile back fretting wear: spectrum analysis found that iron concentration anomaly, iron spectrum, there are many iron composition submicron wear particle, lubricating oil moisture and acid value anomaly.
In liquid lubrication condition, the sliding surface is oil separate and not happen direct contact, but also can greatly reduce friction loss and surface wear, oil film still has certain vibration absorbing ability.single ball bearing
