PARAMETERS OPTIMIZATION FOR QUASI-ELLIPSOID GEAR TRANSMISSION OF ROBOTS

In order to get aid of some drawbacks of spherical gear transmission apparatus assembled in flexible joint ofthe spraying paint robot "Dongfang", this paper has developed a new type of transmission mechanism calledquasi-ellipsoid gear transmission, which can precisely realize variable gear ratio transmission in all directions inspace. In accordance with the requirements of 2-DOF gear meshing, some related parameters about gear ratiofunction and pith surface of the quasi-ellipsoid gear pair are optimized.
