IKO maintenance importance of sliding bearing lubrication analysis

In order to guarantee the normal operation of sliding bearing, and must have good lubrication, rated load and limiting speed of rolling bearings are under the assumption that lubrication to determine the appropriate conditions, the so-called lubrication is appropriate lubricant to choose appropriate, appropriate lubrication dosage, poor lubrication is often cause IKO bearing one of the main cause of early damage. According to statistics, about one-third of the bearing damage due to bad lubrication. IKO bearings in the rotation, bearing wear and failure due to friction. Block rolling bearing rotating by rolling friction, sliding friction and lubricant friction resistance of three kinds of. When the rolling element bearing rolling on rolling rolling friction; Cage guide roller in the surface, keep guard guide surface and roller bearing in the roller end face and ring is happening on the guard sliding friction; The lubricant friction by the lubricant at the contact of internal friction and lubricant of mixing and extrusion. Thus the impedance bearing movement friction resistance for the three combined. And the purpose of lubrication is grease and lubrication way avoid race, rolling element and cage direct contact between metal, reduce friction heat 'make to minimize friction, reducing wear and tear, prevent corrosion, prolong its service life. Because of the sliding bearing antirust processing and packaging, so do not open the packing before installation. In addition, IKO bearing on coating of rust-proof oil has good lubrication performance, for general purposes of bearing or bearing grease filling, can not directly use cleaning. But for the instrument bearing or bearing for high-speed rotation, the application of clean cleaning oil washed away anti-rust oil, when the bearing is easy to rust, not for a long time. IKO bearing and the shell cleaning, confirm no scar or mechanical processing of burr. Shell has absolutely can not have abrasives ( SiC and Al2O3, etc. ) Sand, scraps, etc. Installation method of sliding bearing, for bearing fit, conditions, structure and decide, in general, as more as the axis of rotation, so the inner circle need interference fit. Cylindrical hole bearing, multi-purpose press pressure into, or multi-purpose hot charging method. Taper hole, installed directly on the taper shaft, or use the socket installation. When installed on the shell, clearance fit more commonly, outer ring have surplus quantity, usually use the pressure into the press and or have shrink fit method of cooling after installation. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses on the surface of IKO bearings. So, need a good rust prevention measures. Install the sliding bearing is correct, affect the life, the precision and performance. Therefore, design and installation of assembly department for IKO bearing to fully research. Hope to work in accordance with the standards for installation.
