Wear resistance of TIMKEN sliding bearing wear resistance depends on the sliding bearing material itself, but the sliding bearing wear and the following factors are closely related: for grinding shaft material, hardness, roughness, bearing speed, load and ambient temperature, humidity and so on; as sliding bearing manufacturers, always wear resistance in the optimization of plastics bearing material continuously and provide the correct selection guidance for users; as users must follow the sliding bearing manufacturers product manual on TIMKEN sliding bearing selection and assembly instructions.
Time and any sliding bearing is the key to start the stage. At this time, the lubricating film is not formed and the bearing to work, this is the most common case. As long as the bearing on the work load, TIMKEN bearings will have a slight wear. At the start-up stage, slight wear more fully, will fill with the outer surface of shaft wear particles of these small, so the low wear work can produce optimal lubricating film. After the start, slight wear decreased rapidly, these changes had little effect on the size. Continuous work to start at the end of the wear rate is low and stable.
CSB laboratory testing study found in the imitation of various work conditions, TIMKEN sliding bearing in the wear form basically has the following kinds:
Normal wear -- bearing on the right with conditions occur wear; the bearing wear mainly for the initial stage of lubricating material to the bearing of mill shaft surface transfer results, when the wear rate of lubrication bearing set up ideal will gradually reduce the.
Crawling wear -- because the shaft surface roughness caused by friction surface too smooth crawling; shaft surface too smooth, lubricating material TIMKEN the sliding bearing cannot be transferred to the shaft surface pits filled in to form a lubricating film, makes it ideal for not friction; the friction coefficient of bearing increases, the required driving force also increases;
Ploughing wear -- because ploughing phenomena shaft is too rough to the friction surface scratching; shaft surface height difference is too large, the lubricating material bearing surface transfer was unable to solid form a smooth surface friction ideal; this happens the essence is scratching abrasion wear;
Adhesive wear -- due to scuffing beyond bearing safe operating temperatures or axis caused; safe operation temperature axis allows the bearing operating temperature exceeds the adsorbed on has been bearing friction surface of local softening and the formation of wear.
Burns wear -- due to friction surface wear caused by burn the speed is too fast; shaft speed exceeds the speed allowed by the bearing will cause friction surface due to friction and friction heat up rapidly, the rapid increase of friction heat produced rapid burn injury on friction surface.
Of course TIMKEN journal bearing wear is inevitable phenomenon, in the sliding bearing performance have been determined, we can only follow the rules to use as far as possible every kinds of bearings, TIMKEN bearing wear to a minimum, thus the plastic bearings can play to the best.
