Abstract
The subject stems from the machine-casting factory of Chuncheng of Dafeng City. The design mainly includes the drive system of the sand mixer, the gear, the design and check of the axle, the analyzing and calculation of the general fitting. The S114 type sand-mixture machine uses a 2-stage spiral gear box which not only satisfies to machine transmission and the requirement of bearing capacity, but also makes deceleration facility simple, economical, contributes to manufacture, makes requirement of installation and adjustment low, and makes reliability strong. In the machine design, the following measures have been adopted in order to guarantee technology advancement and economy reliability. Welded WC (tungsten carbide) is adopted instead of direct welding blade of hard alloy According to strength. The scraper reverse sides of welds are enforced in order to increase its strength. After improvement, a pair of scraper may be used for one year in common. It is clean to scrape sand, with few knot sand and little load fluctuation. So, the design will have better prospect of application and practical value.
