【Abstract】 As for the outsize transmission rate needed by lift machine, material test machine and upender, this paper discussed the transmission ratio and efficiency of closed differential speed reducer consisting of orthogonal non hyperbolic gears and presented the corresponding formula for the calculation of transmission ratio. Based on theoretical analysis and experiments the paper determined the transmission ratio, efficiency and deformation velocity of the reducer. It indicated that the reducer is a practical unit of enlarging transmission ratio if the number of teeth is properly selected.更多还原
