Influence of nonlinear stiffness of teeth on dynamic loads in gear transmission

  • Władysław Nadolski


In this paper the influence of the nonlinear stiffness of mating gear teeth on dynamic loads occurring between teeth in a single gear transmission is investigated using a discrete-continuous model consisting of two ponderable shafts torsionally deformed and four rigid bodies. The influence of a weak nonlinearity is discussed for a soft and a hard characteristics of mating gear teeth. Considerations are performed by means of the wave method which enables nonlinear dynamic loads in steady as well as in transient states to be determined.

L'influenza della rigidezza nonlineare di ruote dentate sui carichi dinamici presenti tra i denti di una singola trasmissione a ruote, viene analizzata usando il modello discreto-continuo formato da due alberi ponderabili torsionalmente deformati e quattro corpi rigidi. L'influenza di una debole nonlinearità viene discussa per una caratteristica debole ed una forte di ruote dentate. Vengono fatte alcune considerazioni per mezzo del metodo delle onde che permette di determinare i carichi dinamici nonlineari sia negli stati stazionari che in quelli transitori.
