轴毂连接的主要功能是传递扭矩。多边形轴毂连接是一种越来越重要的轴毂连接类型。与传统的压配合相比，这种类型的连接的主要优点是由于多边形轮廓的偏心而在接触接头中产生了额外的法向力。这导致了传递高静态扭矩的可能性。这些静态扭矩通常在旋转弯曲时发生。因此，组合载荷工况对于轴毂连接的耐用性特别重要。因此，本文对目前未知的多边形轴毂连接的静载荷能力和高周疲劳强度进行了研究。部分研究是由C45E或42CrMo4材料制造的具有次摆线轮廓形状的多边形轴毂连接。静态测试旨在评估达到永久变形点的可传递扭矩。疲劳强度领域的不同测试系列在旋转弯曲或以静态扭转作为平均应力的旋转弯曲下进行评估。根据评估的疲劳强度，计算缺口系数。利用缺口系数，开发了一种多边形轴毂连接疲劳强度的计算方法。
The primary function of shaft-hub connections is the transmitting of torsional moments. The polygon-shaft-hub connection is a type of shaft-hub connection with increasing importance. Compared to conventional press fits, a main advantage of this type of connection is the additional normal force in the contact joint due to the eccentricity of the polygonal profile. This results in the possibility of transmitting high static torsional moments. These static torsional moments often occur with rotating bending. Due to this aspect, the combined load case is of particular importance for the durability of shaft-hub connections. Therefore, the currently unknown static load capacity and high cycle fatigue strength of polygon-shaft-hub connections were investigated in this paper.Part of the investigations were polygon-shaft-hub connections with a hypotrochoidal profile shape manufactured from the materials C45E or 42CrMo4. The static tests aimed at evaluating the transmissible torsional moment up to the point of permanent deformation. The different test series in the field of fatigue strength were evaluated under rotating bending or rotating bending with static torsion as mean stress. Based on the evaluated fatigue strengths, notch factors were calculated. Using the notch factors, an approach for a calculation method for the fatigue strengths of polygon-shaft-hub connections was developed.
