塑料齿轮及其众多应用已成为工业实践中不可或缺的一部分。特别是，使用注塑成型技术生产大量齿轮的成本效益的能力正在为不断增长的市场份额做出重大贡献。然而，与传统的钢材料相比，热塑性塑料的材料特性有着根本的不同。特别是，材料性能的高温依赖性和较低的强度给设计人员带来了挑战。在此背景下，对不同热塑性材料的操作和使用寿命行为进行了理论和实验研究，并进行了评估。除了对齿面承载能力的理论研究外，还对温度特性进行了全面测量，并与塑料齿轮的常用温度计算方法进行了比较。通过对不同材料的背靠背测试及其评估对齿面承载能力进行的实验研究表明，热塑性材料在动力传动系统中的应用潜力。本文将概述所进行的研究工作，并总结这些研究的主要成果。
Plastic gears and their numerous applications have become an integral part of industrial practice. In particular, the ability to produce large numbers of gears cost-effectively using injection molding techniques is making a significant contribution to growing market shares. Compared to conventional steel materials, however, the material properties of thermoplastics differ fundamentally. In particular, the high temperature dependence of the material properties and the lower strength pose challenges for designers. Against this background, theoretical and experimental studies on the operating and service life behavior of different thermoplastic materials have been conducted and evaluated. In addition to theoretical investigations on the tooth flank load carrying capacity, comprehensive measurements on temperature behavior were carried out and compared to common methods of temperature calculation for plastic gears. Experimental investigations on the tooth flank load capacity by means of back-to-back tests of different materials and their evaluation show the potential of thermoplastic materials for the application in power transmitting drivetrains. This contribution will give an overview of the performed research work and summarizes main results of these studies.
