In order to improve the bearing capacity of composite gears

the design is necessary.Using the interface technology between Pro/E and ANSYS software

a 3D parametric model of involute cylindrical spur gear designed in Pro/E is inputted into ANSYS.Short glass fiber reinforced phenolic resin /epoxy resin bulk moulding compound（BMC） composites were prepared by hot press moulding processing and their mechanical properties were measured as the simulation parameters.The simulations analysis of stress status of composite gear made of phenolic resin /epoxy resin BMC under a certain load is made in this paper.The results show that the stress distributions of the composite gear was greatly affected by the relative position between the keyway and loaded teeth.The maximum compression stress of the teeth tip as well as the teeth root was nearly linear with the input load.In addition

a platform appeared in the diagram on the relations between the maximum tensile stress of the teeth root and the input load.Through the researches in this essay

a practical approach for composite gears design were provided.
