Remove the KOYO auto bearing operation key technology

Due to auto bearing belongs to precision machinery parts and components, it is a hard wear resistant materials, its manufacturing generally need after turning, grinding and other processes to complete, it must use such as cutting fluid, grinding fluid has pollution to the environment of the material. With the development of cutting tool and cutting technology, the current domestic and outside of auto bearing adopts dry cutting and cutting has a lot of hard study. But as a result of KOYO bearing is subjected to alternating stress components, how to effectively control the residual stress state on the surface of the processing, become the key to the popularization and application of the technology. First, KOYO bearing periphery remove remove interference fit of the outer ring, beforehand in setting several outer shell on the circumference of a circle of extrusion screw with screws, tighten the screws evenly. To disassemble. The screw hole cover usual blind plug, the separation of tapered roller bearing type bearing, shoulders set several incisions in the shell, this time to use gaskets, and then remove by press or flapping gently remove slowly. Second, cylindrical hole bearing disassembly when remove the inner ring, actually can use press to remove the pull out the most simple. At this time, should pay attention to let the inner ring under the pulling force. Large auto bearing inner ring remove oil pressure method is used. By setting on the axis of hydraulic oil hole, in order to make easy to pull out. Width of KOYO bearing, oil pressure method and drawing fixture and disassembly operations. NU, NJ cylindrical roller bearing inner ring remove can take advantage of the induction heating method. In a short time heating the local, make the inner ring expansion after drawing method. Third, taper hole bearing remove to remove the small KOYO bearing with the set set, need the support of good fastening on auto bearing inner ring, and then turn to the nut back several times, use a block or hammer knock disassembly.
