Anti-reverse differential planet mechanism

The invention provides an anti-reverse differential planet mechanism. The anti-reverse differential planet mechanism comprises an outer gear ring, a planet gear, a planet carrier, a sun gear, an anti-reverse device and a planet carrier input gear. The outer gear ring is meshed with the planet gear, the planet gear is meshed with the sun gear, the sun gear is provided with the anti-reversion device, and the planet carrier input gear is connected with the planet carrier. The transmission efficiency is high, the speed regulation range is wide, and the use requirements of the water feeding pump unit can be met. 本发明提供一种防反转的差动行星机构，包括外齿圈、行星轮、行星架、太阳轮、防反转装置和行星架输入齿轮；所述外齿圈与行星轮啮合，行星轮与太阳轮啮合，太阳轮安装有防反转装置，所述行星架输入齿轮与行星架连接。本发明传递效率高、调速区间广，可以满足给水泵机组的使用要求。
