双圆弧齿轮精确建模与分析

The Analysis and Accurately Modeling of the Double-circular-arc Gear

依据任意转角位置的双圆弧齿轮齿面数学模型,利用Pro/E得到了完整轮齿面的精确齿轮模型.应用模型分析了齿轮的啮合和齿根应力.该模型为双圆弧齿轮的三维数字化设计、有限元分析、虚拟制造等奠定了基础.

From the mathematical model of the double- circular- arc gear teeth surface at any comer, we establish the model of gear fully and accurately with Pro/E, and analyze the mesh and gear- root stress with the model. The model establishes the base for the 3D digital design, analysis of the finity unit, dummy manufacture of the double - circular- arc gear.
