Abstract
This paper introduces a simulator which can depict the rotational vibration of a helical pair having any kind of deviations transmitting light load. Under light load condition the contact pattern does not extend to full length of ideal contact tooth surface. Under this condition, the determination of the contact pattern sometimes become very sensitive to the numerical calculation error. In the worst cases, calculation leap into endless loop. The developed simulator was improved robuster.
This paper firstly derives how we can obtain the relationship between the deflection and the load distribution of single pair of mating teeth. Secondary, the determination method of multi tooth pair load sharing is introduced. Afterwards, the simulation is experimentally verified with various kinds of tooth flank deviations.
Through this study, an easy design method to realize a low vibration helical gear is suggested.
