Title:
WASHER
Document Type and Number:
WIPO Patent Application WO/2017/170550
Kind Code:
A1
Abstract:
A mating member 8a rotates in the direction of an arrow D2. A washer 1 rotates in the direction of an arrow D1 in accompaniment with the rotation of the mating member 8a. In the gap between a tapered section 12a and the mating member 8a, a lubricant flows in a -θ direction viewed from the washer body, and the lubricant flows into a region Ra that gradually becomes narrower in the -θ direction. A "wedge effect" occurs thereby, and the pressure increases in the gap between a first surface 10a and the mating member 8a. In the gap between a tapered section 12b and a mating member 8b, the lubricant flows in a +θ direction viewed from the washer body, and the lubricant flows into a region Rb that gradually becomes wider in the +θ direction. An effect that is opposite the "wedge effect" occurs thereby, and the pressure decreases in the gap between a second surface 10b and the mating member 8b.
