The key step in the separated type KOYO bearing installation method

Separation because the inner ring and outer ring of bearing installed easily loaded on the shaft or housing, respectively. At this point that should be noticed are will be insert has installed the axis of the inner ring has been packed outer ring of bearing box, try to keep it together, to prevent scratches rolling element and raceway. To KOYO bearing inner ring with tight fit of the shaft and outer ring of bearing hole is a loose fit the separation type bearing for installation, separation because the inner ring and outer ring of bearing installed easily loaded on the shaft or housing, respectively. At this point that should be noticed are will be insert has installed the axis of the inner ring has been packed outer ring of bearing box, try to keep it together, to prevent scratches rolling element and raceway. For KOYO bearing inner ring with tight fit of the shaft and outer ring of bearing hole is a loose fit the separation type bearing for installation, can press the bearing installed on the shaft first, then the shaft together with the bearing to the bearing hole, if the bearing is lesser, also can use a soft metal hammer tap ring end face to force bearing, but striking force must be evenly distributed on the bearing ring. Bearing outer ring and bearing hole for tight fit, inner ring and shaft for a loose fit, the bearing can be installed on the shaft. When the bearing ring and shaft or bearing seat hole is a tight fit, the installation of the application of a special set of barrel at the same time the bearing pressure to the shaft or the bearing seat. When KOYO bearing size is bigger, because the required installation force is bigger, or work under heavy load bearing fit interference is bigger and the cold installation are in trouble, you need to add the bearing inner ring or bearing seat in advance after hot again for installation. When installed in hot, should strictly control the heating temperature. Maximum bearing heating, the heating temperature should not exceed 1200 c, should be in commonly 80 ~ 1000 c. With dust cover or seal bearing can not heating, otherwise it will cause loss of lubricant. Heating mode can be adopted electric induction wind, oil bath heating method, etc. To select the most appropriate coordination, must consider the following: 1, 2, the direction of the load, the load characteristics of 3, load size 4, the condition of temperature 5, install and remove the conditions on KOYO bearing installation or hollow shaft in the thin wall bearing hole, you must provide a larger than normal interference fit. Don't recommend split housings for high precision or tight hole, otherwise the split bearing may cause deformation of outer ring. About KOYO bearing abnormal sound, is a new problem is an old problem. Say it is a new problem, because it is in recent years the bearing vibration value from low to develop in the direction of mute, exposed the problems in the process of bearing quality enhances unceasingly. Said it is an old problem, because in the early stages of the pursuit of low vibration, no noise of bearing quality put forward higher requirements, but bearing abnormal sound is objective existence, once the bearing vibration value stability decreased to a certain level, abnormal sound is apparent. Value of most of the low noise, vibration and abnormal sound and so on three kinds of different class KOYO bearings, according to their vibration peak from low to high order is: low noise bearings, bearing abnormal sound, vibration value of bearing. This shows that there are abnormal sound bearing vibration acceleration peak value under low noise level and vibration value of bearing between the two. Therefore, with the sound of the valid values to evaluate bearing abnormal vibration of misjudgment rate is higher.
