Modeling and Analysis of Kinetic Characteristics of a Gear-Linkage Mechanism

A gear-linkage mechanism, composed of a planetary gear mechanism and a four-bar mechanism, has the characteristic of step-cyclical output rotation under a reasonable geometric parameters. The analysis of stepping movement of the base unit and the motion characteristic of the combined mechanism was made, and the parameter equation was figured out. Motion simulation was carried out to analyze the influence of transmission ratio on the variation of the output shaft angular displacement, which proved that the output steps was in correspondence with , and as value of increasing, the rollback of the output motion was more apparent. The gear-linkage mechanism can be applied to engines, pumps and compressors.
