Friction loss optimized rolling bearing

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，最常用的机器元素。它们都需要支持或指导相对移动的零件。不仅尝试减少燃油消耗和任何类型的车辆的二氧化碳输出，而且都会考虑每个滚动轴承系统。到目前为止，对于许多具有高摩擦损失的应用滚动轴承，例如锥形滚子轴承可以通过轴承损失明显较低的轴承设计来代替。部分可以用新型的轴承来处理，这些轴承确实显示出适当的性能特征。例如，在乘用车的轴齿轮箱中使用的标准使用的锥形辊轴承可以用双排滚珠轴承的新设计代替。但是，对于其他应用，没有这种解决方案可以减少可用的摩擦损失。其中属于重型卡车的轴齿轮箱（由于负载轴承功能不足，无法使用命名的双排球轴承）。作为减少此类系统摩擦的可能概念，可以命名Kegeltonnenlager。这种轴承设计已在机器元素，齿轮和变速器研究所进行了实验测试，并证明了其功能。该项目旨在在一个由三部分组成的项目中开发出一种新的轴承，从而导致重型应用中的摩擦损失减少。首先，理论基础将解决。然后将获得基于模拟的几何形状的优化。然后，将对最终设计进行实验测试，以证明执行的作品。
