Title:
METHOD FOR CONTROLLING SUPPLY OF LUBRICANT, DEVICE FOR CONTROLLING SUPPLY OF LUBRICANT, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/010071
Kind Code:
A1
Abstract:
Provided is a method for controlling supply of a lubricant to a device configured such that a plurality of portions are lubricated with the lubricant, wherein: the impedance of an electronic circuit including the plurality of portions is measured by applying alternating voltage to the electronic circuit; the oil film thickness and the oil film fracture rate between the plurality of portions are derived on the basis of the measured impedance; and the amount of supply of the lubricant to the device and/or the timing of the supply is controlled on the basis of the derived oil film thickness and the derived oil film fracture rate so that a lubrication state between the plurality of portions can be a prescribed lubrication state.
