The TIMKEN sliding bearing abrasion resistance vary depending on the wear resistance of the bearing material itself, but the sliding wear of the bearings is also closely related to the following factors: the grinding shaft material, hardness, roughness, bearing operating speed, load, and ambient temperature, humidity etc.; plain bearings manufacturers, always constantly optimize the wear resistance of the plastic bearing material and to provide users with the correct selection guide our work; as the user to follow the plain bearings manufacturer product manuals TIMKEN plain bearings selection and assembly instructions for use.
The most critical moment of sliding bearings is the start-up phase. In this case, the lubricating film is not formed and bearings begin to work, which is the most common situation. Bearing a work load, TIMKEN bearings will produce minor wear and tear. Minor wear more fully in the start-up phase, will use these fine wear particles filling the outer surface of the shaft, so the low wear when working can generate the optimal lubrication film. Starts, minor wear decreased rapidly, little impact of these changes on the size. Continuous work after the end of the start-up phase, the wear rate and stable.
CSB laboratory test study imitation under various operating conditions found, TIMKEN sliding bearings work wear form are the following:
Normal wear and tear - bearing wear occurs with the use of the correct conditions; bearing wear performance of the lubricating substance in the initial stage of the work bearing a result of the transfer to the surface of the shaft bearing when creating the ideal lubrication vice wear rate is slowly reduced.
Crawling wear and tear - the shaft surface roughness caused friction surface is too smooth crawling; shaft surface is too smooth, the the TIMKEN sliding bearing lubricating substance can not be transferred to fill the shaft surface pits form a lubricating film, makes it ideal for friction pairs can not be established; when the bearing friction coefficient increases, also increases the required drive force;
Furrows wear - caused because the shaft is too rough the friction surface scratches furrows phenomenon; shaft surface height difference is too large, the lubricating substance can not be transferred from the bearing surface to form an ideal solid smooth friction surface; wear essence at this time scratch resistance to wear and tear;
Cemented wear -; adsorption the local softening has occurred in the bearing friction surface formed by the optical axis of the bearing operating temperature exceeds the allowable safe operating temperature when wear exceeds the safety bearing operating temperature or the optical axis caused by gluing.
Frictional heat of friction burns - burns due to running too fast due to the friction surface wear; axis running faster than the permissible operating speed bearing wear will cause the friction surface frictional heat due to friction from a sharp rise, a sharp rise the surface of the fast burns.
Of course the TIMKEN sliding bearing wear occurs the phenomenon can not be avoided, in the case of the sliding bearing performance has been determined, we only possible to follow the usage rule for each of the different models bearing to minimize the wear of the the TIMKEN sliding bearing, which will The plastic bearing performance to play to the best.
