As an important role in the chain of power and control information transmission, it has a unique function to form the power equipment for the wheel and transmit the energy and control information to the wheels, it is more convenient and automatic by comparison with the driving bridge and central transmission. This design is based on the already known products and the precondition of the working need and other limiting conditions. The first part of this article is try-and-match, then calculates the transmission ratio and the intensity and structure of gears, then build the three-dimensional designing model, in motion and finite element model analysis, lastly we get the optimal design. Key words: hub reduction, planetary gears, three-dimensional designing, try-and-match, emulation, optimization, distribute of transmission ratio. 目录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc294103535 1 前言  PAGEREF _Toc294103535 \h 1  HYPERLINK \l _Toc294103536 1.1 课题背景  PAGEREF _Toc294103536 \h 1  HYPERLINK \l _Toc294103537 1.2 国内外相关产品  PAGEREF _Toc294103537 \h 1  HYPERLINK \l _Toc294103538 1.3设计内容  PAGEREF _Toc294103538 \
