In order to reduce the weight and vibration of Electro-hydraulic Transmission, the composite gear was studied, a new type of steel phenol composite transmission gear was put forward, and its optimal design was given. In this method, the polymer composite was placed between the steel tooth and the central hub area along the radial direction of the gear, so as to reduce the vibration transmission rate from the tooth to the hub and the weight of the gear train. In order to minimize the weight of the composite gear, the optimum size of the radial composite zone of the gear was calculated by considering the fatigue strength of steel and composite materials. The results show that, compared with pure steel gears, the average sound pressure levels of optimized and un-optimized composite gears are reduced by 7.2% and 4.6%, respectively, and the average acceleration is reduced by 15.3% and 12.0%.
