Abstract: A new method was put forward based on Westhoff meshing transmission interference evaluation system. The method was used to judge whether there exists interference between the enveloping tooth profile and pulley tooth groove of the double helical synchronous belt transmission. Then a new double helical synchronous belt was designed and the conjugated tooth profile transmission model was induced on the basis of the double helical transmission characteristics. It is shown that there is no meshing interference in the new double helical synchronous belt compared with the Eagle PD; the higher and steeper the belt tooth, the stronger the resistance ability to climb. The new normal tooth profile is effective to improve the contacting strength while the radius is larger and the instant engagement line is longer, where the point of the conjugated circular arc is on the pitch line.

Key words: technology of instrument and meter, double helical synchronous belt transmission, eagle PD, transmission interference and simulation, conjugated tooth profile, circular arc tooth
