The invention relates to an HMCVT three-planet-row converging mechanism of a high-power tractor. The mechanism comprises a three-planet-row converging mechanism body, a tooth-embedded connection further-optimized planet gear mechanism and a tooth-embedded connection further-optimized planet gear mechanism. The three-planet-row converging mechanism body comprises a needle bearing, a sun gear P1, a shaft elastic check ring, a motor shaft driven wheel, a shaft elastic check ring, a deep groove ball bearing, a driving wheel sleeve welding part C3, planetary gear shafts P1P2 , a needle bearing spacer bush, planetary gears P1P3, a planetary carrier P1, an elastic pin, a gear ring P1, a planetary gear P2, a planetary carrier P2, a gear ring P2, a needle bearing, a driving wheel gear ring welding part C1 and a thrust copper gasket. The device solves the problem that a single-stage planetary gear transmission system cannot meet the engineering operation requirements of low speed, heavy load and large torque, the problem of concentricity of the sun gear, the planetary carrier and the gear ring of the HMCVT converging mechanism of the high-power tractor is solved, and the problems of uneven load and stress unbalance loading in the meshing process of the planetary row gears are solved.
