  • Device for measuring frictional force and film thickness of lubricating oil film in different surface velocity directions
    Patent number: 11768149
    Abstract: A device measures a frictional force and a film thickness of a lubricating oil film in different surface velocity directions. The device includes an experiment bench. A translation stage is mounted to the experiment bench, and is linearly movable. A main shaft system is mounted to the experiment bench. A glass disc is mounted to the main shaft system and is rotatable. An arcuate guide rail is disposed on the translation stage. A rotary base is mounted to the arcuate guide rail and is movable along the arcuate guide rail. A loading system is mounted to the rotary base. A steel ball of the loading system and the glass disc are movable relative to each other. A rotary bearing in the rotary base is configured to convert a frictional force generated from the relative movement to a pressure allowed to be collected by a pressure sensor on the rotary base.
