摘要/Abstract

摘要： 结合有限元分析及滚花试验,研究了三点轴向滚花过程中轴体表面应力、应变分布规律,滚齿形成过程,以及滚花刀参数对刀具负荷、装配过盈量、装配压装力及静扭强度的影响。结果表明:三点滚花工艺成齿饱满,轴表面金属流动充分且未超过材料破坏应力;滚花刀齿高和齿顶角是决定刀具负荷、装配过盈量、压装力及装配件静扭强度的重要因素;滚花数值模拟与试验结果基本吻合,可以为滚花装配工艺参数的制定提供可靠依据。

Abstract: The three rollers axial knurling process of assembled camshaft is investigated by experiment and numerical simulation, including the distributions of stress and strain and their changes on the surface of the tube, the formation process of tooth profile of the tube, the effect of parameter of knurling tools on the tools' load, the assembly interference quantity, the press-fit and torsional strength. Results show that the tooth profile formed by three point knurling technology is complete and satisfactory, and the metal can flow sufficiently, and the stress does not exceed the material failure stress. The tooth height and addendum angle are important factors in determining the tool loading, assembly interference quantity, press-fit and torsional strength. The simulation and experimental results are in good agreement, which can provide a reliable reference for the selection of axial knurling process parameters.

Key words: mechanical manufacturing process and equipment, assembled camshaft, axial knurling, numerical simulation, press-fit, static torsional strength
