Abstract：The high speed gear of wind turbine generator is as the research object , this paper researches on gear crack based on finite element analysis method , and the effects of crack depth and crack location on the contact and meshing stiffness .The test result indicated that with the occurrence of crack gear , the crack serves as the boundary the tooth was divided into two parts , and the deformation stress was discontinuity .With the deepening of the crack depth , the divides was more obvious .With the different of the crack locations , the step mutation may come during meshing process , in each of the meshing regions , the meshing stiffness shows the dif-ferent lowering rate .It is some significance for the research of the gear crack fault and prevention of tooth frac-ture and other serious accidents .
