A Novel Approach in the Application of Flexure Bearings in Primary Torque Standard Machines

摘要

An important characteristic of the bearing application in ultraprecise torque realization is small and predictable friction. However, other equally important requirements are the stable definition of the rotary axis and high repeatability. These requirements cannot be derived without a significant improvement in the typical characteristics of customary bearings. Flexure bearings provide favorable characteristics for torque realization. This work presents different variants of flexure bearings. It is shown how to predict flexure bearing behavior in order to enable the compensation of systematic fault effects. This therefore opens the way for the bearing requirements of ultraprecise torque realization.
