What are the installation methods of angular contact ball bearings?
1.Using hot loading method:
When the interference of the bearing fit is large, it is difficult to install the bearing using a pressure device, and it is easy to damage the bearing's mating surface. Therefore, if the inner ring of the bearing is heated and expanded, the bearing will be easier to install into the spindle.
At present, magnetic induction heaters are often used to heat the inner ring of the bearing using the thermal loading method. The heating temperature of the bearing should not exceed 120C. The specific heating temperature depends on the size and interference of the bearing.
Since the size of the outer ring of the bearing also becomes wider during the heating process of the bearing, it is easy to create an axial gap with the shaft shoulder after the bearing is cooled. After the bearing is cooled, it will be in an interference fit state with the main shaft. Therefore, the thermal assembly method is used When the bearing is cooled, nuts or other suitable methods should be used to eliminate the axial clearance between the bearing and the shaft shoulder.
2.Inject pressure oil between mating surfaces:
When there is interference between the shaft and the bearing, the friction between the mating surfaces is very large. When the interference is large, the mating surface may be damaged. If pressure oil is injected between the mating surfaces, the two mating parts will be slightly deformed, and the pressure oil will penetrate into the mating surfaces and form a lubricating oil film, which can greatly reduce the friction between the mating surfaces. In this way, the two mating parts can slide relative to each other with less force. This method is suitable for both the installation of conical surface fittings and the assembly and disassembly of cylindrical surface fittings.
