摘　　要：提出了剃齿刀结构三维模型设计思想,利用有限元软件ANSYS对剃齿刀结构进行了受载条件下的应力应变模拟。研究了刀齿齿根应力和应变的分布规律,提出了刀齿齿槽结构的改进方案。结果表明:采用改进的齿槽结构可以使刀齿齿根最大应力降低36%,刀齿齿根最大应变降低20%。The designing idea of 3D structure model of the gear shaving cutter was presented, and the structure of gear shaving cutter was simulated by the finite element software ANSYS to get the model of stress and strain under the load. The distribution law of stress and strain along the cog-tooth was researehed, and the structure of grooved cog was improved. The result indicated that the improved structure of grooved cog could reduce 36% of the maximum stress and 20% of the maximum strain in the root of tooth.
