Summary:In order to avoid the interference and lateral clearance between the non-circular synchronous pulley and synchronous belt, to improve the carrying capacity and transmission accuracy of the synchronous pulley, and to reduce the noise in the process of transmission. In this paper, the conjugate engagement theorem of generating method was applied to the calculation of the tooth profile of the non-circular synchronous pulley. The tooth profile of synchronous pulley was obtained by enveloping the pitch curve of non-circular synchronous pulley with a rack cutter and a local quadrant method was proposed to extract the complete tooth profile points based on the distribution characteristics of the data points of the envelope curve. The auxiliary design program was compiled by MATLAB, and through the calculation and comparison of examples, it was found that the method was simple, reliable, and highly accurate.
