Open publisher page 0 citations

Abstract

The method and procedures of exact modeling for the involute gear based on Pro-E was introduced,it is proposed that the involute was established using equation to ensure the accuracy of involute gear form.The gear model is transformed to the finite element model consisting of nodes and elements utilizing the interface technology between Pro/ E and ANSYS software and ANSYS software.Then NR method is used to get the statics solution by contact stress,and the arithmetic principle is introduced.The new contact element method proposed is validated to be precise,valid and reliable.The research results can provide reference for the optimization design of the gear.
