This paper finished to a secondary planet gear reducer structure design. Compared with domestic and foreign existing reducer, the reducer are more transmission ratio, and it has the structure is compact, the small size and light weight profile, etc. This paper first introduced the present situation and the subject at home and abroad and spiral unloading centrifuge differential about the research progress of the outline and development trend, and then compared the all kinds of transmission structure, so as to determine the basic types of the transmission. Paper main body part is to the transmission structure design and calculation on the design of the whole structure of the calculation and check. For the design and manufacture of differential provides sufficient theoretical basis. 意见与反馈 参加有道翻译用户满意度调查！
