Title:
RING MEMBER FOR ROLLING BEARING RACEWAY RING AND ROLLING BEARING
Document Type and Number:
WIPO Patent Application WO/2011/155434
Kind Code:
A1
Abstract:
Disclosed are a ring member for a rolling bearing raceway ring and a rolling bearing that provide improved quality due to sufficient tempering and welding of cavities, cost reductions due to the elimination of the need for a step to punch out a central section, etc., reduced energy consumption, and reduced resource consumption due to increased yields. The ring member (1) is formed from steel, a rod-shaped member (w) rolled into the cross-sectional shape of the ring member (1) is formed into a ring shape, and the end surfaces of both ends are bonded to each other. The bond is a weld or other liquid-phase bond. The ring member (1) is used as a raw material prior to machining in the raceway ring of the rolling bearing. If used as such, the ring member (1) has an annular groove (3) formed in the trajectory groove of the rolling bearing. The bond section (1a) is strengthened by friction stir welding after rough turning of the ring member (1) that achieves a shape approaching the cross-sectional shape of the bearing raceway ring.
