Abstract: In this paper, we first introduce the determ ination of engaging point, and the characteristics of involute、conjugate profile. In section 2, we present methods for determ ining the modification coefficient, helical angle, and geometric size of low number teeth involute spur gear mechanism. Some conclnsions are drawn in section 3. The gear is to improve the design parameters of gear modeling efficient and effective way, based on the Pro/E Wildfire platform for accurate modeling parameters of the function of an editorial Pro / E of the model program, has less teeth gear design automation modeling, and To achieve the basic parameters change gears automatically generate a new gear. The gear design allows designers to quickly and easily achieve the three-dimensional characteristics of gear design, thereby improving the efficiency of the design.
Key words: Coordinate Conversion; Low-number Teeth; Modification coefficient; PRO/E software; Transmission; Simulatio
