Abstract
A tribometer and technique for determining torque at a physical interface of multiple rotating components. The tool and technique include aligning components about a rotational axis for independent rotation of each component. The components are in physical interface during the rotating with a resultant frictional torque. The torque may be measured by one or more torque meters during the rotating. This measured torque may be compared against an estimated torque for tool accuracy. Further, parameters such as load, temperature, component material, rotating rpm differentials and others may be varied to determine effect on measured frictional torque.
