| Abstract: | Starting from analyzing the stress of roller bit motion and the working situation, the author considers that early losing effectiveness of the O-shaped rubber seal ring is inevitable and proposes using the X-shaped seal ring or end-face seal without gap to replace the O-shaped seal ring and using polytetrafluo-roethylene as the sealing material to replace rubber. |
