Abstract First introduced two cylindrical gear reducer research background, research on domestic and international significance, as well as the status quo, by reference to a detailed analysis on the two cylindrical drive the concept, design and the main transmission, such as the strength of the relevant content In the technical line, Gear on the choice of structure, the basic parameters of the size and geometry, the two main strength of checking in, such as the need to be considered in the design of some technical problems are introduced. Reducer on the spur gear in the transmission type of layout options, the box design. Some parts of the auxiliary design, lubrication and sealing, and other related issues briefly described. In this paper, the belt conveyor reducer design. Key words: Cylindrical helical gears layout form box design
auxiliary parts sealed lubrication
