The design of timing belt drive systems involves determining the belt width and belt length. The length of the belt is a geometry problem which requires summing the tangent lines and the arcs comprising the pitch line. The width of the belt is determined by the required loads. A computer program is developed in this project to automate the timing belt design process. The program comes in three versions. Each version chooses a target belt length, moves a specified pulley to achieve that length, then calculates the minimum belt width. The three versions of the program are the batch version, the interactive version, and the McAuto version. The batch and the interactive version are accessed from a standard computer terminal. The McAuto version is linked to the McAuto CAD system at Eastman Kodak Company. The McAuto version creates McAuto menus, selects information from the graphics screen, then draws results on the screen which become part of the design file.
