一种双行星排四轴传动装置
摘要：
本发明涉及一种双行星排四轴传动装置。包括外齿圈、行星架、行星排，太阳轮，其特征在于所述的行星排为分前行星排和后行星排的双行星排结构，前行星排和后行星排分别对应一个太阳轮，前排行星齿轮为小齿宽、大分度圆，后排行星轮为大齿宽小分度圆，前排行星分别与外齿圈和小太阳轮相啮合组成前排轮系，后排行星分别与前排行星和大太阳轮相啮合组成后排轮系。实现了一种在后排轮系的太阳轮与外齿圈之间的传动比较大的双行星排四轴传动装置。
摘要（英）：

The invention relates to a double-planetary gear four-axis transmission device, which comprises an outer gear ring, a planet carrier, planetary gears and sun wheels, and is characterized in that: the planetary gears are divided into a front planetary gear and a rear planetary gear to form a double-planetary gear structure; the front planetary gear and the rear planetary gear respectively correspond to one sun wheel; the front planetary gear is a small-tooth width large-scale division circle; the rear planetary gear is a large-tooth width small-scale division circle; the front planetary gear is respectively engaged with the outer gear ring and a small sun wheel to form a front planetary gear train; and the rear planetary gear is respectively engaged with the front planetary gear and a large sun wheel to form a rear planetary gear train. Therefore, the double-planetary gear four-axis transmission device with large transmission ratio between the sun wheel of the rear planetary gear train and the outer gear ring is realized.
