Evaluation of sealing performance of bearing rings of roller-cone bits based on grid-shaped bionic non-smooth surface

Based on the bionic non-smooth surface theory, this article carries out (1) design of the structure of bionic non-smooth sealing rings and toothed bars of the sealing structure and (2) finite element simulation study on the bionic non-smooth surface structure of roller-cone bits. The result shows th...
