11 bearing preload method is used to improve the bearing rigidity of non-standard bearing price bearing preload method is used to improve the bearing rigidity of ball bearings or tapered roller bearings can take axial preload method, radial on short cylindrical roller bearing can be preloaded method, can significantly improve the rigidity of shaft bearing or eliminated the bearing clearance, or had little negative clearance.
But the speed is not too high, under the condition of temperature rise modestly, should also be transferred to the best little negative clearance status.
When applying preload, should be constantly measuring the deformation situation, pay attention to in the low stage of the deformation, deformation is nonlinear with the increase of the pre-tightening load;
And in the stage of high value, deformation are linear with the increase of the load.
Once the deformation load appears linear relation, then stop immediately increase pre-tightening load, has been a constant stiffness can be obtained at this time.
Since then, non-standard bearing axial rigidity and there is a fixed relationship between the radial rigidity, and not dependent on the applied load.
