通过塑性成形连接机器部件是传递力和扭矩的常用方法。在传动系统中，“滚花过盈配合”通过摩擦连接和形状配合的组合具有高传动能力。在本研究中，由C45钢材料制成的轴试样与由16MnCr5表面硬化钢制成的内滚花轮毂连接。通过试验研究了连接工艺参数对轴毂连接扭转疲劳强度的影响。最重要的参数是滚花轮毂的倒角，它决定了材料的应变硬化率，并且在切削和成形连接工艺之间存在差异。研究表明，滚花过盈配合连接，通过形成连接实现了更高的疲劳强度和更高的最大静态扭矩比通过切割连接。
The joining of machine parts by plastic forming is a common method for transmitting forces and torque. In drive trains, the ‘knurled interference fit’ has a high transmission capacity through the combination of frictional connection and form fit. In the present study, the shaft specimen made of C45 steel material is joined with an inner knurled hub made of 16MnCr5 case hardened steel. The influence of the joining process parameters on the torsional fatigue strength of the shaft-hub connection is investigated by means of experimental studies. The most important parameter is the chamfer angle of the knurled hub, which determines the rate of strain hardening in the material and differs between the cutting and forming joining processes. This study shows that knurled interference fit connections joined by forming achieve a higher fatigue strength and a higher maximum static torque than connections joined by cutting.
