项目摘要

Rolling bearings belong among the most reliable and most used machine elements. They are used wherever relatively moved parts need to be supported or guided. Not only in the attempts of reducing the fuel-consumption and the CO2-output of any kind of vehicle, each rolling bearing system is thought over and optimized. Up to now for many applications rolling bearings with high frictional losses, e.g. tapered roller bearing, could be replaced by bearing designs with significantly lower frictional losses. Partly this could be handled with new types of bearings, which do show appropriate performance characteristics. As an example the standardly used tapered roller bearings in axle-gearboxes of passenger cars could be replaced by a new design of a double rowed ball bearing. However, for other applications there are no such solutions for reducing the frictional losses available. Among these belong e.g. axle-gearboxes for heavy-duty trucks (the named double rowed ball bearings cannot be used due to insufficient load bearing capabilities). As a possible concept for reducing the friction in such systems the Kegeltonnenlager can be named. This bearing design has been experimentally tested at the Institute for Machine Elements, Gears and Transmission and proven its functionality. The project aims to develop a new kind of bearing in a three-part project leading to reduced friction losses in heavy duty applications. At first theoretical basics will be settled. Then a simulation-based optimization of the geometry will be acquired. The final design then will be tested experimentally to prove the works performed.

滚动轴承属于最可靠和最常用的机械部件之一。它们用于需要支撑或引导相对移动的部件的任何地方。不仅在试图降低任何类型车辆的燃油消耗和二氧化碳排放方面，每个滚动轴承系统都经过了仔细的考虑和优化。到目前为止，对于许多应用来说，具有高摩擦损失的滚动轴承，例如圆锥滚子轴承，可以被摩擦损失显著降低的轴承设计所取代。这在一定程度上可以通过新型轴承来解决，这些轴承确实表现出了适当的性能特征。例如，客车桥变速箱中标准使用的圆锥滚子轴承可以被一种新设计的双列滚珠轴承所取代。然而，对于其他应用，没有这样的解决方案来减少摩擦损失。其中包括重型卡车的桥式变速箱(由于承载能力不足，不能使用已命名的双列滚珠轴承)。作为在这类系统中减少摩擦的一种可能的概念，可命名为凯格尔顿拉格。该轴承设计已经在机械零件、齿轮和变速器研究所进行了实验测试，并证明了其功能性。该项目的目标是在一个由三部分组成的项目中开发一种新型轴承，以减少重型应用中的摩擦损失。首先，理论基础将得到解决。然后，将获得基于模拟的几何优化。最终的设计将进行实验测试，以证明所完成的工作。
