摘要
为研究材料在螺旋锥齿轮滚轧成形过程中的流动规律,采用有限元分析法对螺旋锥齿轮滚轧成形过程中的坯料咬合、滚压分齿、连续滚轧成形及整形4个过程进行模拟分析。结果表明,滚轧成形过程中滚轧轮与目标齿轮需满足齿轮传动比运动关系;滚轧轮与坯料初始咬合量的大小对分齿过程有较大影响,最佳咬合量为1 mm左右;在滚轧过程中,材料沿滚轧轮表面流动,逐渐成形出目标齿轮;随着滚轧成形过程的进行,材料的变形加剧,所需成形载荷增大。
In order to study the pattern of material flow in the rolling process of spiral bevel gear,a finite element analysis was conducted of four rolling processes of spiral bevel gear blank occlusion,rolling parting,rolling forming and rolling shaping.Simulation results show that the rolling wheel and the target gear need to form the gear ratio motion in the rolling deformation process;the initial engagement depth of rolling wheel and billet has a great influence on the gear-splitting forming process with the best engagement depth at about 1mm;the material flows along the surface of the rolling wheel to gradually form the forming gear;and the deformation of the material becomes more and more serious and the forming load increases with the rolling process.
