| Abstract: | The irregular vibration of chain and the harm of crawling in the casting machine were firstly analyzed, the crawling kinetic model of linear chain casting machine was established. The crawling was caused by the big difference between static and dynamic friction coefficient and insufficient stiffness of the system. A new roller system and hydraulic tension apparatus were designed to prevent the crawling of chain belt effectively. |
