  • On the Kinematics of Spatial Gearing
  • Published at:Not Found
  • In this paper, using screw theory, complete descriptions for the relative motion of a pair of spatial gears, whose axes (shafts) may simultaneously rotate and translate, are given. These descriptions are then used to derive the point coordinates of the pitch surfaces corresponding to some practical shafts layouts and/or shafts input-output relations are also generated and given in the example section.
