DYNAMIC LOADS ON THE TEETH OF SPUR GEARS

Abstract

It is generally recognized that dynamic loads on the teeth of spur gears having pitch error, profile error or elastic deflection under load, may be very different from the mean load which they are transmitting. Considering more precisely the above problem, as Hertz's impact theory, the dynamic load will be determined depending on the flexural vibration of the teeth and the amount of relative approach between the mating gear teeth in contact. Therefore, the problem of dynamic load on gear teeth caused by impact can be treated as that of beam impact in substance.
