Introduction to the installation process of roller bearings

Installation and adjustment of rolling bearings: Couplings and clearances of rolling bearings require rolling bearings to meet the requirements of high-precision bearings and high-temperature bearings, so the following two points should be considered in the fit and clearance: dimensional change and hardness change from normal temperature to high temperature ; Force change and shape change caused by high-speed centrifugal force.

In short, under high-speed and high-temperature conditions, it is difficult to maintain the accuracy and working performance of the bearing by selecting the fit and clearance. In order to ensure that the roller bearing after the roller bearing is installed is small in deformation, the interference fit cannot be made too large , And high-speed centrifugal force and thermal expansion at high temperature, or offset the normal pressure on the surface.

Or cooperate with surface slack, so the above two factors must be considered to calculate the interference amount carefully, and the effective interference at normal temperature and speed may be invalid for the roller bearing, if the calculation results are too contradictory (usually only at super high speed) , Only the dual lubrication measures used in the ring lubrication method and the static pressure lubrication method, this solution is feasible.

Make the dmn value of the bearing exceed 3 million marks. Thermal expansion at high temperatures may counteract normal pressure on mating surfaces. Or cooperate with surface slack, so the above two factors must be considered to calculate the interference carefully, and the effective interference at normal temperature and speed may not be effective for roller bearings.
