Spatial Cam Modeling and Analysis on Curvature of Conjugated Surfaces

Abstract:

A novel limited slip differential mechanism for wheeled vehicle is introduced in this paper. A new modeling method for spatial cam mechanism used in the differential is detailed derived. The melding method and the formulas of induced normal curvature for conjugate surfaces of the cam mechanisms is derived on basis of meshing theory of conjugated surfaces and differential geometry theory, and the results provide theoretical foundation for the cam optimization.
