Abstract

One of the main goals during load calculations and vibration analysis for gears is the determination of deformation and stress state in teeth contact zones. This paper describes development of the finite element model for simultaneously monitoring the deformation and stress state of teeth flanks and teeth fillets for spur gears during the contact load period. The paper also describes the Finite Element Method simulation of contact conditions for spur gears teeth with complete 3 Dimension meshing model. A suitable analysis is performed in order to select a meshed gears model which is sufficiently economic and in same time sufficiently geometrically accurate. The special algorithm for the tooth profile drawing is developed and built in currently available software (Ansys 10) for Finite Element Analysis to assure drawing of real flanks contact geometry. The optimal mesh size level is chosen, too. The described finite element models are made for the spur gear teeth during the dynamic loading state. The obtained numerical results are suitable for tracking deformation and stress hesitation with time and investigating the effect of damping coefficient on the obtained results.
