近年来，工程师们在许多应用中寻找低功率损耗的替代品，其中使用了高摩擦损耗的滚动轴承，例如圆锥滚子轴承。具有较低摩擦损失的新型轴承已被设计以满足这一需求。以乘用车车轴齿轮箱中常用的圆锥滚子轴承为例，采用新设计的双列滚珠轴承代替了圆锥滚子轴承。然而，仍有一些应用尚未找到理想的替代品。一个例子是用于重型卡车的车轴齿轮箱，由于承载能力不足，不能使用双列球轴承。一个可能的概念，以减少摩擦在这样的系统是锥形桶滚子轴承可以命名。基于其几何形状，将进行基于仿真的优化，以开发一种新型轴承，从而减少重型应用中的摩擦损失。本文将给出这些模拟的结果。作为进一步的研究，最终的设计将进行实验测试，以验证结果。
In recent years, engineers have searched for low power loss alternatives in many applications where rolling bearings with high frictional losses were used, e.g. tapered roller bearing. New types of bearings with lower frictional losses have been designed to cover this need. As an example, the commonly used tapered roller bearing in axle-gearboxes of passenger cars has been replaced by a new design of a double rowed ball bearing. However, there are still some applications where no ideal alternative has been found yet. One example are axlegearboxes for heavy-duty trucks, where double rowed ball bearing cannot be used due to insufficient load carrying capabilities. A possible concept for reducing the friction in such systems is the tapered barrel roller bearing can be named. Based on its geometry, a simulation-based optimization will be performed in order to develop a new kind of bearing leading to reduced friction losses in heavy-duty applications. The results of these simulations will be presented in this paper. As a further investigation, the final design will be tested experimentally to validate the results.
