The Application of Tooth Contact Analysis in the Shaper Modification for Face-gear

To get ideal position of contact area for face-gear drives, we researched beginningly the rack-cutter modification, setted up equation of tooth surface of parabolic rack-cutter. According to the machining coordinate systems of shaper and the gear geometry and applied theory. The surface equation of shaper was established by using the equation of rack-cutter tooth surface and matrix for coordinate transform; The gear teeth surface equation of face-gear was got base on machining coordinate systems and the surface equation of shaper. Comprehensively considered the meshing relation among shaper, pinion and face-gear, the coordinate systems of meshing analysis were founded; The equations of meshing contact points for face-gear drives were established; Recurring to the technology of computer simulation, the effects between the face-gear meshing contact path and shaper modification were researched through the computational examples. So, The position of contact area for face-gear drives is controlled.
