Solid self-lubricating bearings are mainly JDB-1, SF-1, FB09G, and other series of bearings, in the initial stage of the work gradually through the wear and tear self-lubricating material gradually transferred to the grinding surface of the workpiece surface formed in the hard lubricating film; Its friction and wear properties mainly rely on the performance of solid lubricants, self-lubricating bearings face material is usually copper alloy, aluminum alloy - bimetal, babbitt, PTFE, modified polyoxymethylene, rubber, Molybdenum disulfide, black lead and the like. Which can form a solid lubricating film on the surface of the solid self-lubricating bearing to separate the moving sub-surface, the sliding frictional force can be greatly reduced, and the wear of the shaft can be avoided.
Solid self-lubricating bearings and shaft sliding friction occurs, [url=http://www.bearingtypes.com/Filled-and-Modified-Fluoroplastic-Series.html/] Filled and Modified Fluoroplastic Series [/url] and the shaft in the process of running to transmit torque and movement, so the hardness of the shaft material and strength requirements are higher, JDB-1 self-lubricating bearings commonly used metal to wear parts, hardness HRC40 °; [url=http://www.oilitebronze.com/product/DU-F-flanged-bushing.html] DU-F flanged bushing SF-1 bushing [/url] is lower, the use of the general 45 # steel can also be. For the friction and wear properties of solid lubricants mainly rely on the performance of solid self-lubricating bearing bearing capacity, high precision rotary, solid lubricating film with impact resistance.
The solid lubricating film is solid self-lubricating bearing surface material itself has good self-lubricating properties, in the initial stage of the work gradually through the wear and tear self-lubricating material gradually transferred to the grinding surface of the workpiece surface formed in the hard lubricating film; This is the roughness of the grinding surface of the workpiece have certain requirements, the general requirements of Ra0.4 ~ 1.6 between; too smooth or too rough surface is not conducive to the transfer of lubricant to the work surface hindered the completion of the lubrication film; Solid lubricating bearings are generally required to be grinding the surface to the polished surface; when the solid lubricant film is fully formed, the movement between the shaft and the bearing has actually changed into a friction between the lubricating film and the bearing movement, [url=http://www.oilitebronze.com/product/Iron-Bushing.html] Oil Sintered Iron Bushing [/url] is not directly practical In contact with the bearing surface.
