Abstract:This design mainly introduces the selection and design process of screw conveyor in which four parts are included:motor selection,the design of V belt transmission ,the design calculation of gear reducer,the selection of screw conveyor and accessory drive cylinder body and the installation and adjustment of screw conveyor.In calculating, the screw diameter in the delivery cylinder and the rotate speed together with the power of spiral shaft will be chiefly concerned, so as to reach a collection of required data for model selection. Based on these data, with screw conveyor design manual as guidance and other related reference books and information as complement, the shape and mounting dimensions, the related data and size of the main components as well as the actuating devices that all conform to the requirements of screw conveyor will be worked out. Finally, the tutor will accomplish the model selection and design process of screw conveyor.
