Title:
BEARING
Document Type and Number:
WIPO Patent Application WO/2020/246620
Kind Code:
A1
Abstract:
The inner bearing ring and the outer bearing ring of conventional bearings have different diameters, so when the outer bearing ring is fixed and the inner bearing ring rotates, the rolling elements move opposite the direction of rotation of the inner bearing ring. This bearing is characterized in that, by configuring the contact positions of the rolling elements to contact the outside of the inner bearing ring on the small-diameter section and contact the inside of the outer bearing ring on the large-diameter section, even if the outer bearing ring is fixed and the inner bearing ring rotates, the rolling elements do not move opposite the direction of rotation of the inner bearing ring.
