An electrically insulated block-on-rotating-ring test unit and method, to evaluate the effects of electrical potential on material pairs and fluids under mechanical load and in sliding contact. The fluids may comprise lubricants and oils utilized in electrical vehicles.

Electrically insulated block-on-rotating-ring test unit and method

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.

Frictional torque determination technique

A device and method for measuring temperature during tribological examination of sample materials. More specifically, the device includes a sample holder that provides for surface temperature measurement for sample materials undergoing tribological testing.
