The AGMA dynamic factor has traditionally been treated as adynamic “load” factor where tooth load is the sum of all of thetooth forces that are applied along the plane of action at anyinstant in time. Knowing the total load, however, says little aboutthe degree of load sharing or the load position on a tooth when thedynamic load is a maximum. Hence, the dynamic load factor does notdirectly address the value of either dynamic contact stress ordynamic root stress; quantities that a gear designer should be moreinterested in. This paper’s main focus is the prediction of dynamicroot stresses. The approach presented in this paper is a relativelysimple methodology that does not use finite elements. The methodmerges the capabilities of a sophisticated load distribution anddynamic excitation prediction method with a time domain geardynamics simulation. Because a time integration type of simulationis used, the method can handle both steady state and transientinputs. Inputs that are possible include tooth profile and leadmodifications, misalignments, and spacing errors. These can take onaverage values or can have discrete changes applied from tooth totooth. Examples of the use of some of these errors are provided inthis paper.
