The design formulae for skew line gear wheel structures oriented to the additive manufacturing technology based on strength analysis
Abstract. In this paper, the design methodology for a skew line gear pair oriented to additive manufacturing technology, with an one-tooth driving line gear and its coupled driven line gear, used for the conventional powered transmission, is researched based on strength analysis. First, the expressions of meshing forces on the line tooth of line gears are deduced; the deformations and stresses of existing structures of a line gear pair are analyzed by using ANSYS Workbench. Then, the reliable structure and the parameters standardization formulae of a line gear pair are deduced by stiffness and strength analyses. Finally, a design case shows that the proposed design methods provide a convenient and reasonable design tool for designing a skew line gear pair in conventional powered transmission field.
