Modern electric machinery requires the use of conductive ball bearing greases. The project sponsor, Axel Christiernsson International AB, has outlined requirements for a device to test grease under simulated conditions of an electric motor. The machine combines all of the requirements, including operating at speeds above 10,000rpm, measuring milli-Newton-meter range torques, and isolating an electric current to the test bearing. This report outlines the process to design a test rig to be constructed in August 2018. The final design consists of a belt transmission, ceramic support bearings, cantilevered test bearing in custom housing, an electric circuit, nut and screw loading, PT100 temperature sensor, and friction torque measurement by load cells.
