Bearing rear axle drive important components of wheel movement. Thrust ball bearings in the main compound, able to withstand bending and torsion, and absorb some of the impact load. Overall carbon alloy axle after hardening steels commonly used in induction heating and hardening to harden, hardened layer depth of 4-6mm and hardness 50?55HRC. SKF bearings found, often bearing burned out, seriously affecting the quality of the production of bearings and parts induction hardening. Tests showed that 225 in coil bearing burned out areas. In the vicinity, extending the regularity of the fault on both sides. Axle sensor heating, in addition to heating the workpiece, in major heat loss in one of three ways of heat generated by the sensor. Overload, there is also the chance of fracture and fatigue fracture of races, especially the bearings of the poor conditions of service (such as 22,328). Study on fracture phenomena of races, not only from material and manufacturing defects produced during these look also for bearing part of the structure size, process measurements, processing technology, thrust ball bearings, research and analysis of factors such as conditions of service. FAG bearing structure and conditions of service. Different structure adapted to different conditions of service; processing technology of bearing structures vary, also affects its quality. So we should develop a new structure in order to adapt to different conditions of service, and bearing instructions indicated on the appropriate conditions of service or performance, to facilitate the customer's choice. (1) heat to the surrounding radiation. Guidance magnets, induction loops in the paints and glass fiber cloth. This form of heat loss, heat evenly, and Burnout has little effect on the sensor. (2) heat of cooling water. This part of the cooling sensor, safety operation of induction heating. Studies have found that in 0-180, intake water temperature low, indicating good heat exchanging cooling water, water well, water temperature; More than more than 180. Because the stream length, elevated water temperatures, water temperature, and heat exchange variation, because the sensor can easily result in a site (for example, 225. Part) temperature rise, which is the main induction loop combustion. (3) induction loop heat transfer plates, part of the current density, large size and low water temperature, area in the region, heat transfer coil. Quarter and 0-90 degrees of induction loop near facing away from the Board, good thermal conductivity, and away from the plate, heat conductivity is poor, 90 per cent of the Induction coil, induction loop temperature in the region more prone to burned coil in this part of the phenomenon. Heat flow in different parts of the induction loop. In the region of around 225 degrees heat-sensing circuit, and made savings and therefore prone to combustion phenomena of induction loops in the area varies between. Study on strengthening process, improve processing, improving quality, reducing the likelihood of defects in the process. On the heat treatment, on inner and outer rings of larger varieties, as far as possible with minimum hardening heating temperature, adaptation to extended holding time to improve the alloy concentration, increasing the fracture strength of martensite, and guarantee the quality of choice on higher tempering temperatures to enhance the toughness of the workpiece. Improving process monitoring tools, promoting the improvement of machining quality. Road curvature location monitoring such as improved circulation, improving the overall performance of NSK bearing after Assembly, improved working conditions bearing.
