Abstract
This topic designs Honda manual transmission with 5 gears, grasps the working principle of manual transmission, and designs the shaft and gear of manual transmission. First of all, through the study of the existing transmission, understand the design ideas and design points of the transmission. This topic focuses on the design of the 5 speed manual transmission. The main contents are the design, calculation and verification of gears, the design, calculation and verification of shaft, and the use of Autocad to draw two-dimensional drawings. In gear design, the relationship between gear ratio and gear strength should be taken into account, so as to meet the requirements. In terms of shaft design, the size and stiffness of the shaft are mainly taken into account to satisfy the requirements.
Key words: manual transmission; transmission shaft; gear; design; check
