Parameter design and three-dimensional modeling of non-circular planetary gear mechanism

Aimed at the particular advantage of the variable center distance non-circular planetary gear mechanism in its application in hydraulic motor,its operation principle and principle and composition were introduced and then an analytical model of SOK-type hydraulic motor with non-circular planet gear was established.On the basis of theoretical analysis and by using softwares Matlab and CAXA,the solution of pitch curve and generation of 3-D modeling were conducted for 46-type planet gear mechanism with variable center distance.The three-dimensional entity of generated gears could be used for assembly design,motion simulation and computer-assisted teaching.
