Installation and Adjustment of High-speed Bearings
In modern industrial production, bearing plays an important role, and its efficiency and service life are related to its installation and adjustment. The installation and adjustment of high speed bearing is particularly important. In this paper, we will discuss the installation and adjustment of high speed bearing.
The installation of high speed bearing includes several aspects. The first is to clean the components and the surface of the mating parts. If the components and the surface of the mating parts are contaminated, it will affect the connection between the parts and the bearing. Secondly, preload and stiffness should be set according to the application condition. In order to prevent bearing damage, preload should be set according to the requirements of matching parts. Thirdly, the correct installation technology should be used. The bearing should be pressed in or out by press or other special tools, and the hammer or other rough tools should not be used to avoid damage to the bearing. Finally, pay attention to the bearing direction. When installing the bearing, the direction of the axial and radial force should be in the same direction, so as to avoid the bearing being crushed and damaged.
After the installation of high speed bearing, the adjustment is also very important. The adjustment includes radial clearance adjustment and axial preload adjustment. In order to ensure the stable operation and high performance of the bearing, the radial clearance between the inner and outer rings of the bearing should be adjusted in the range of 0.1-0.5% of the outer diameter of the bearing. The method of adjusting the radial clearance is to adjust the interference fit or preload of the outer ring. In addition, the axial preload also needs to be considered when adjusting the radial clearance. When adjusting the axial preload of the bearing, the preload should be as small as possible, so that the bearing can run smoothly and stably.
In short, high-speed bearings are widely used in industrial production and need to be installed and adjusted. The installation of high-speed bearings includes cleaning and selecting installation tools, setting preload, setting stiffness and paying attention to bearing direction. The adjustment includes radial clearance adjustment and axial preload adjustment. Only when the installation and adjustment are scientific, can the high-speed bearing run stably and smoothly and extend its service life.
