行星差动轮系功率分流和传动比的内在规律及速算法

Inherent Laws and Fast Calculation Method of Power Dividing and Transmission Ratio of Planetary Differential Gear Train

以履带式行走机构的三级行星差动轮系为例,用解析法分别推导该机构功率分流、传动比通式,并揭示差动行星机构功率分流与传动比的内在规律及速算法,通过进一步说明,提出差动行星机构的串、并联关系,将差动行星轮系简化成一般行星轮系。

Taking the three planetary differential gear train of crawler walking mechanism as an example, the mechanism power dividing and transmission ratio formula are derived by analytical method, the inherent laws and fast calculation method of planetary differential gear train power dividing and transmission ratio are revealed. By further ex- planation, the serial connection and parallel connection of planetary differential gear train is proposed, planetary differ- ential gear train to general planetary gear train is simplified.
