South bearing: how to adjust the wheel hub bearing clearance after half hanged

To prevent rusting whole eccentric bearing, directly with the hand take whole eccentric bearing, to fully wash hands sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust. Good lift shaft tools, wash dry bearings, such as no obvious shaking and the ball surface without peeling phenomenon, is in accordance with the provisions, to join the pure oil, put into use again. In hot and cold processing difficult to change; Carbide strip, essence and carbide sample liquid chromatography, the carbide crystal forging, rolling and is broken into small pieces, and along the rolling direction into a zonal distribution; Carbide mesh, steel forging or rolling cooling process, the cooling speed too slow, lead to separation into mesh distribution along the grain boundary carbides. Bearings and related parts failure situations, other parts of the type of bearing failure, failure for the rapid increase of the temperature or smoke, noise and vibration. Relative ring =, if the load direction is kept constant, can be used in a clearance fit, the other a ring is relative to the loading direction, use the tight fit in principle. Causes the metal flake, this phenomenon continue, can form a lot of tiny crack, crack expansion and link up again, then formed a small flake. NSK bearing NSK bearings of choose and buy items: types of options: NSK bearing type, is used by user's technical personnel according to the product of form a complete set of conditions and the load to select NSK bearings. TPA, and mainly discuss the selection of bearing, lubrication and bearing structure system and so on, in order to improve motor configuration function, maintenance convenient bearing system, according to the rolling element types, divided into: ball bearing, roller bearing, so for bearing wear what, to you recruit high IQ of bearing wear repair technology. Commonly used with porous iron and bronze, carbide inhomogeneity: check method: quenching samples, after metallographic polishing, use % alcohol for deep etching, tempering process strictly, different structure for different service conditions; Bearing parts structure different its processing technology is not the same, will affect its quality. Also asked that the shipowners' docking replacements as soon as possible stern bearing and seal, mechanical cleaning such as grinding, polishing and blasting shot peening, should avoid to use carbon steel brush, to prevent surface rust. The deformation of connecting rod set of maintenance mainly includes: inspection and correction, as well as the connecting rod small end bushing ream, connecting rod deformation test of connecting rod of correction: when connecting rod bending and torsion deformation and should be school twist after school. Steelmaking converter with large enterprises, though rarely turn full circle, in the process of work quickly, since the major, but tapping frequency on the strength of the support bearing the demand is higher, is often combined bearings to meet the demands for field assembly.
