通过结合轴承的具体优势，组合滚子轴承和滑动轴承可用于满足高性能机床日益增长的要求。由于其敏感的功能性，坚固的轴承设计对其工业适用性是必不可少的。不同的轴承类型导致不同的，有时是相互矛盾的要求。本文介绍了一种设计方法，包括工业上适用的轴承组合的基本设计规则。该方法尊重在力流分配到不同的轴承部件的目标的冲突。轴承刚度用作轴承功能能力的指标。基于流体动力润滑理论的半解析模型被扩展为滚动轴承模型来模拟轴承的行为。此外，进行了全旋转和枢转试验，以验证模型，并研究转速和径向位移对轴承刚度的影响。
By merging bearing specific advantages, combined roller and plain bearings can be used to meet the increasing requirements for high performance machine tools. Due to their sensitive functionality, a robust bearing design is indispensable for its industrial applicability. Different bearing types lead to different and sometimes contradictory requirements. This article presents a design methodology including basic design rules for industrially applicable bearing combinations. The methodology respects the conflict of objectives in the distribution of the force flow to the different bearing components. The bearing stiffness is used as an indicator for the bearing’s functional capability. A semi-analytical model based on the theory of hydrodynamic lubrication was extended by a roller bearing model to simulate the bearing behaviour. In addition, both full-rotation and pivoting tests were carried out to validate the model and investigate the influence of rotational speed and radial displacement on the bearing’s stiffness.
