The Mesh Characteristics of Arch Cylindrical Gear and Its Digitization Analysis

As a new kind of cylindrical gear, the in volute arch cylindrical gear has preferable transmission characteristics, but its main geometry parameters have no unified standard. In this paper, the ideal geometry parameters of in volute arch cylindrical gear are proposed and its tooth surface equation and meshing line equation are discussed. For verification, the computer graphics is introduced to show the meshing characteristics. By programming, tooth surface and meshing line are discretizesd, fetching some points and linking these points by short straight line to present the lines and surfaces which are visualized to show meshing characteristics. Simultaneously, a process way for arch cylindrical gears is proposed.
