A method to define profile modification of spur gear and minimize the transmission error

The object of this article is to propose a simple method to reduce the transmission error (T.E.) for a given spur gear set, at the nominal torque, only by means of the profile modification parameters. Iterative simulations with advanced software, are needed. A hybrid method has been used, combining the Finite Element technique with semianalytical solutions. A 2D analysis is thought to be adequate for this kind of work, in fact, this software requires both little time for model definition and simulations, with a very high precision of the results.
