To ensure a stable operation to install INA turbocharged bearing technology

Of INA bearings produced in the process of operation, is difficult to handle. Because of the improper handling of words, will cause bearing damage, but when its life expectancy. Bearing clearance should proper, too big impact, is too small, poor lubrication is likely to cause it to further deteriorate. Surface quality of the bearing and shaft neck and geometry must be strictly guaranteed. Improve into bearing lubrication quality, control the pressure, temperature, strengthen the cleaning and filtration. Use of lubricating oil for lubrication. To ensure the long life of INA bearings, cannot meet the requirement from general installation and adjustment, and should focus on the following several steps: ( 1) Bearing according to the interference fit the size of the surface groups, each group of turbo bearing again according to the clearance size in sequence. The corresponding shaft or hole diameter, the same group. The interference fit surface size of INA bearings with large diameter shaft group or a hole set corresponding matching, and the small size and small diameter matching corresponding group. In each of the corresponding set of matching, to get tighter clearance of the bearing to cooperate, little bearing clearance is a loose fit. Such matching results, in the same batch of installation of the machine, the interference fit is more uniform bearing, neither too loose, but also tight, clearance is relatively uniform, so as to ensure the prestressed fitting of bearings after installation, and avoid peristalsis, ring throwing, burst, due to the improper clearance and the shock, vibration or fever, such as well as the occurrence of abnormal bearing failure. ( 2) At the ends of the supporting shaft neck and coaxial degree of hole and the end of the bearing perpendicularity to guarantee strictly, prevent the formation of the additional load. If possible, outside of turbo bearing load function of mechanical components should be a little away from that end of the damaged bearing more easily, at the same time axis and the rotating system to smooth operation as soon as possible.
