BTU for light duty ball transfer bearing China Factory

Postprzez slidebushing » 2018-07-05, 04:32

Main fault sliding bearing
BTU for light duty on the job as a result of the journal and bearing contact will produce friction, surface cause fever, even "killed", so in the design of the bearing, should choose sliding bearing materials with good płeć of anti-friction bearings, suitable lubricant and adopt the suitable method to supply, improve the bearing structure for thick film lubrication, etc.
1, tile surface corrosion: spectrum analysis found that non-ferrous metal element concentration anomaly;Spectrum appeared a lot of non-ferrous metal components of sub-micron wear particles;Lubricating oil excess moisture, acid value exceeds bid.
2, shaft neck surface corrosion: spectrum analysis found that iron concentration is unusual, there are a lot of iron in iron spectrum of submicron particles, water or high acid value oil paint.
3, a shaft neck surface strain: iron spectrum have iron series cutting grinding grain or black oxide particles, metal surface heat tint.
4, tile back micro wear: spectrum analysis found that iron concentration is unusual, there are a lot of iron in iron spectrum wear submicron particles, lubricating oil moisture and acid value anomalies.
5, DU oilless bushing surface strain: iron spectrum found cutting abrasive, abrasive ingredients for non-ferrous metal.
6, tile surface spalling, finds many large size iron spectrum fatigue spalling alloy wear particles, the layered grits.
7, bearing tile burning: there are more iron spectrum by means of large size, alloy and black metal oxides.
8,Ball transfer bearing: as the axis of the metal properties (hardness, poor concessions) wait for a reason, easy to cause adhesion wear, abrasive wear, fatigue wear and fretting wear condition.
