ROLLING BEARING DEVICE AND ROTARY DEVICE

Document Type and Number:

WIPO Patent Application WO/2006/075741

Kind Code:

A1

Abstract:

A rolling bearing device and a rotary device. The rolling bearing device comprises an oil supply unit supplying a lubricating oil in a tank by a pump through a nozzle opening in an annular space between an inner ring and an outer ring. The nozzle opens in a space between the inner peripheral surface of a retainer and the inner ring, and the inner peripheral surface of the retainer is formed to be continuously or intermittently reduced in diameter gradually starting at its axial center part to at least the insertion side end part of the nozzle. Thus, the lubricating oil dripped on the inner peripheral surface of the retainer can be prevented from flowing out to the outside of the bearing by flowing it to the axial center part by a centrifugal force caused by the rotation of the retainer.
