Abstract: The double circular arc gear GB/T12759-1991 is taken as the object of research,and it is accurately modeled and analysed with finite element method by using the UG software. The gear bending strength is studied before run-in period with load on the theoretical meshing point. The bending strength distribution along tooth depth direction,the change of stress with different load position and the main failure mode of the gear are analyzed. And the reason of why the tooth is broken at deddendum or midposition of the tooth is studied. The relationship between the main profile parameters of the double circular-tooth gear,including the whole depth h,the nominal pressure angle α,tooth profile arc radius ρ,is also analysed and their selection principle is discussed. The results of this paper provide a theoretical support for further analysis.
