Application of Integrated Design of the Belt Drive System Based on the Platform of Research and Development of the VBA

In order to the integrated design of the geometric parameters and drawing the pulley parts, based on R & D platform of the VBA with the CAD software, hence after analyzing the selection belt type, determine the reference diameter of the belt pulley, choosing length and the amount of the belt, and designing and drawing the pulley parts, in which include the drawing the tooth of v belt pulley, chamfers and grooves, keyway, hatches, and part dimension, etc. Conventional belt drive system is successfully developed. The design results show that the program is running smoothly, the result is correct with the friendly interface, it can provide a convenient tool to rapidly design of project for the belt drive system.
