Asymmetric modification method of cylindrical rolling body, terminal and computer readable storage medium

Abstract

The invention discloses an asymmetric modification method of a cylindrical rolling body, a terminal and a computer readable storage medium. The invention discloses an asymmetric modification method for a cylindrical rolling body, which comprises the following steps of: firstly, acquiring a load borne by a rolling bearing, analyzing a stress state of the cylindrical rolling body, performing non-equal slicing treatment on the cylindrical rolling body based on the load state of the cylindrical rolling body, and performing precise slicing treatment on a stress concentration part of the cylindrical rolling body. And the stress state of the stress concentration part can be obtained more accurately. Meanwhile, the initial modification amount of the cylindrical rolling body is reasonably designed based on the loaded state of the cylindrical rolling body, the asymmetric initial modification amount is adopted, the initial modification amount of the stress concentration part of the cylindrical rolling body is increased, the initial modification amount is closer to the final modification amount, the accuracy of the finally obtained modification curve is guaranteed, and meanwhile the iterative optimization process is simplified. The invention further discloses a terminal and a computer readable storage medium.

Description

technical field [0001] The present application relates to the field of bearing design, in particular to an asymmetric modification method of a cylindrical rolling body, a terminal and a computer-readable storage medium. Background technique [0002] Cylindrical rolling element bearings are widely used in transmissions due to their strong load capacity and good fatigue resistance. However, after the straight generatrix cylindrical rolling element is loaded, it will inevitably produce large local stress concentration at both ends. When the local stress exceeds a certain limit, it will cause the rolling bearing to fail, seriously affect the working life of the bearing, and cause serious economic losses. In view of the bearing disadvantages and application limitations of straight generatrix cylindrical rolling elements, the Swedish scientist Lundberg proposed the basic theory of generatrix modification of cylindrical rolling elements based on the theory of elasticity in 1939, an...
