In this paper, the cause of high vibration, high temperature and short spin arm bearing on ordinary three-ring gear reducer in operation is analyzed In accordance with the problems and according to equilibrating load principle of oil-film floating, reducing vibration and assimilation vibration of synchronous belt, power separation flow and mechanism dynamic balance principle, the authors design a new three-ring type gear reducer of oil-film floating, and the reducer is of full balance, equilibrating load and reducing vibration.The reducer uses synchronous belt transmission as one-stage transmission and comes true synchronous input of three-ring transmission The two side ring plates of three inner ring plates are arranged symmetry and phase 180° to the middle ring plate The equilibrating load principle of oil-film floating device on new three-ring type gear reducer is analyzed .The mechanism transmission efficiency and equilibrating load experiments of prototype machine show that its transmission efficiency is about 92.3% and its load distribution non-uniform coefficient is about 1.1 after equilibrating load.
