Non-metallic material of sliding bearing
2017-07-18
Bearing plastic: commonly used bearing plastic phenolic plastic, nylon, polytetrafluoroethylene, plastic bearings have greater compressive strength and wear resistance, available oil and water lubrication, but also self-lubricating properties, but poor thermal conductivity.
Sliding bearings in the work due to contact between the journal and the bearing will produce friction, resulting in surface heat, wear and even "killed", so the design of bearings, should be used to improve the friction of a good sliding bearing material bearing, the appropriate lubricant And the use of appropriate supply methods to improve the bearing structure to obtain thick film lubrication.
1, tile surface corrosion: spectral analysis found that non-ferrous metal element concentration anomalies; spectrum appeared in many non-ferrous metal components of sub-micron wear particles; lubricants moisture exceeded, acid value exceeded.
2, the journal surface corrosion: spectral analysis found that iron concentration anomalies, iron spectrum has many iron components of sub-micron particles, lubricating oil moisture or acid value exceeded.
3, journal surface tension: iron in the iron cutting grain or black oxide particles, the presence of metal surface tempering color.
4, tile back fretting wear: spectral analysis found that iron concentration anomalies, iron spectrum in many iron components submicron wear particles, lubricating oil moisture and acid value anomalies.
5, bearing surface strain: iron found in the cutting abrasive, abrasive composition of non-ferrous metals.
6, tile surface peeling: iron spectrum found in many large-scale fatigue exfoliation alloy wear particles, layered abrasive.
7, bearing burning tile: iron spectrum in the larger size of the alloy abrasive and ferrous metal oxide.
8, bearing wear: due to the metal properties of the shaft (high hardness, poor concession) and other reasons, easy to cause adhesive wear, abrasive wear, fatigue wear, fretting wear and so on.
