摘　　要：为了改善齿轮副的对角接触现象,将常规弧齿锥齿轮的渐缩齿改为等高齿齿形,采用0号刀齿铣齿,从理论上避免对角接触。基于齿轮的局部啮合原理、齿面接触分析(TCA)技术和承载齿面接触分析(LTCA)技术,对相同条件下等高齿设计与常规齿轮设计的实际接触区、载荷及应力应变进行了分析。分析与加工试验结果表明:理论与实际接触区位置基本相同,所受力的大小以及应力分布也基本相同。与传统的齿轮设计相比,等高齿弧齿锥齿轮设计保证了齿轮强度、齿轮啮合质量,使其接触区规范且易于调整,有利于提高加工效率。In order to improve the diagonal phenomenon of gear pair,conventional spiral bevel gear tapered teeth was changed into constant-depth tooth with No. 0 cutter while milling. Based on local meshing principle of gears,tooth contact analysis( TCA) technology and loaded tooth contact analysis( LTCA) technology,the actual contact area,load and stress-strain of contour gear design and conventional gear design were analyzed under the same conditions. Theoretical analysis and expriments indicate that the theoretical and actual contact area are basically the same. The size of the force and stress distribution are basically the same. Compared with the traditional gear design,the constant-depth tooth bevel gear design ensures the gear strength and gear meshing quality. The contact area is easy to adjust,which improve its processing efficiency.
