Development of Grease Film Breakdown Observing Device

The paper describes a newly developed smart device, which can detect the dielectric breakdown of the grease elastohydrodynamic film formed between a steel ball loaded against a glass disc due to electric discharge, while observing the shape and thickness of the film. The electric discharge between c...
