It is composed of a two.stage gear reduction. Compared to single.stage advantage is obvious, ground clearance is relatively large, and is designed to give a higher gear ratio, and also has a simple structure, and quiet operation, the application of sufficient age and so on. The content of the design include: the design method study of unreasonable designed to improve analysis. Design and Verification gear and the gear shaft and the bearing selection and verification.In order to better determine the program. Full parameters of the original application, compared to similar models of the main reducer technology development, and optimize the matching ratio, and features a great influence on the effect of strength parameters were checked. The bearing arrangement is designed to ensure work more safely and efficiently complete the design standards.</p><p>Keywords: Final reduction drive; Gear; Check; Design</p><p>目 &nbsp;錄</p><p>摘要<span
