The installation of NSK bearings and the extension of service life

1, NSK bearings, NSK bearings installed installation and removal methods, NSK bearings should be based on the structure, size and cooperate with NSK bearing parts of nature. Therefore, research in the design and installation of assembly department fully. You want to install according to the standard. The task of this project are as follows: standard (usually 1) NSK bearing inner ring and the shaft is a tight fit, outer ring and shell as a loose fit, available press NSK bearings will be pressed on the NSK bearings first, then the axial load along with NSK bearing shell, when pressed on the NSK bearings end face cushion a soft metal materials assembling casing ( Copper or soft steel tube) 。 Assembling casing inside diameter should be slightly larger than the diameter of a journal, NSK bearing outside diameter should be less than inner diameter of the rim diameter, to avoid pressure in keeping the frame. Large when installing NSK bearings can add a handle on the casing. ( 2) NSK bearing inner ring and the shaft, the outer ring and shell holes are tight fit, assembling casing end should be made to NSK bearing inner and outer ring width at the same time compression ring, or with a disc and assembling casing, make the pressure at the same time to the inside and outside the circle, the NSK bearing pressure into the shaft and housing. This kind of installation method is especially suitable for NSK bearings can automatically self-aligning centripetal spherical installation. ( 3) NSK bearing outer ring and shell holes for tight fit, inner ring and the shaft for a loose fit, NSK bearings can be pressed into the housing first, then assembling casing diameter should be slightly less than the diameter of the shell hole. ( 4) The NSK bearings before heating installation, hot charging or separable NSK bearing ring into the fuel tank or dedicated heater evenly heating to 80 ~ 100 ℃ ( Should not exceed 100 ℃) 。 2, NSK bearings after installation, need to be adjusted, straightening exposed to NSK bearings may result in additional load, friction, and vibration. This could accelerate fatigue and reduce the life span, and it might damage the other machine parts service life. In addition, the vibration and friction could significantly increase the risk of and premature failure. 3, in the process of operation, NSK bearings requires correct lubrication again, perfect its performance. NSK bearing lubrication method, divided into grease lubrication and oil lubrication. NSK bearings in order to make the function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. Grease lubrication but have around NSK bearings can simplify the structure of the special features. 4, when NSK bearings will reach its final use period, should be replaced. Although NSK bearings can no longer be used, but properly unloaded the original NSK bearings, NSK bearings timely replace new, to extend the service life of new NSK bearings can play a good role in promoting. First of all, the use of appropriate tools unloaded method will help prevent for other machine components of the damage, the second, is not correct to unload the technology may cause harm to the operator. 5, in use process, often should basic external conditions of NSK bearings running monitoring, such as temperature monitoring and measurement of vibration and noise, etc. Make production plan, improve plant productivity and efficiency.
