Abstract
This paper presents an economic model of designing agricultural tractors gearbox. First location the consumer of the products. Comparison of various types of design related to the formation .I owned my design ideas and determine a preliminary design. After that collected a variety of data, and further improve the design. Then learn more about the production of similar products in the manufacturing process in order to understand the various components of the design and production parts. First of all, complete the overall product design, so that products meet the required functions. rationale for the allocation of the transmission ratio , determine the speed of every file. And then design the various parts of the respective parts, considering the strength of gears and shafts, gears meshing reasonable, reverse rotation of the layout and the choice shift. Through the comparison of similar functional components. In meeting the functional to the extent possible, to reduce costs. Finally, improving the auxiliary part of the products, lubrication methods, lubricants, etc. Final complete the design of products.
