Connecting transition mechanism for prolonging service life of winding of double speed reducer

The utility model discloses a connecting transition mechanism for prolonging service life of a winding of a double speed reducer. The connecting transition mechanism for prolonging the service life of the winding of the double speed reducer comprises a winding drum which is connected with a speed reducer through bolts. The speed reducer is connected with a transition disk through bolts. The transition disk is connected with a rack through a pin roll. According to the connecting transition mechanism for prolonging the service life of the winding of the double speed reducer, the transition disk is, after connected with the speed reducer which is used to wind through bolts, fixedly connected with the rack used to wind through the pin roll. The number of gear engagement surfaces which are caused by the movement of a gear in the speed reducer along the axle direction is reduced. Radial force impact which is received in the torsion transmitting to the speed reducer is eliminated. The inner gear is uniformly engaged
