Mori等人（2013）确定了当前对不同材料的更高性能、更高生产率、更低成本和连接的商业需求，从而导致对新连接的强烈需求，特别是通过成形工艺连接。当通过轴的横向挤压连接轴-毂连接时，建立了形式和摩擦锁紧连接的组合。轮毂内廓形在周向上对成形过程和连接性能有重要影响。内轮毂的齿形主要由齿形偏心e、齿数n和齿形类型来表征。本文主要研究了轮毂内轮廓参数对成形过程和零件性能影响的实验研究。为了确定合适的内轮毂轮廓，其特点是低冲头力，最小和均匀的径向变形和高轮毂腔填充，进行了许多成形工艺，其中所述轮廓参数是不同的。为了评价轮毂内轮廓对冲头力-行程曲线、轮毂圆度偏差和轮毂空腔填充的影响。
Mori et al. (2013) identified the current commercial requirements for higher performance, higher productivity, lower cost and joining of dissimilar materials to lead to a strong demand for new joining and especially joining by forming processes. When joining a shaft-hub-connection by lateral extrusion of the shaft a combination of form- and friction locked join is established. The internal hub profile which defines the form-closed joint in circumferential direction significantly affects the forming process and hence connection properties. The internal hub profile is mainly characterized by the profile eccentricity e, the number of teeth n and type of profile. This study mainly deals with the experimental investigations concerning the influence of the internal hub profile parameters on the forming process and part properties. To identify a suitable internal hub profile characterized by low punch forces, minimal and homogeneous radial deformations and high hub cavity filling numerous joining by forming processes are carried out wherein the mentioned profile parameters are varied. To evaluate the influence of internal hub profile the punch force-stroke curves, the roundness deviation of the hub and the hub cavity filling are used.
