Optimization Design of the Plural Row Rolling Disc Displacement for Trocoid Tooth Reducers to Minimize Transmitted Angle Erro

Abstract

This paper describes an optimization design process of the rolling disc displacement of Trocoid tooth reducers. The reducers with plural row disc will have larger transmitted angle error than the reducers with single row disc. We analyze the mechanism that the reducer of the plural row disc causes larger angle error, and derive an optimal displacement angle of the plural row disc to minimize angle error. Simulation study and experimental trial show the strong effectiveness of this design process.
