RETAINER SEGMENT FOR TAPERED ROLLER BEARING, TAPERED ROLLER BEARING, AND METHOD FOR MOUNTING TAPERED ROLLER BEARING

摘要

An object of the present invention is to prevent breakup of segments which constitute a split type retainer for a tapered roller bearing, when the tapered roller bearing is being mounted on target equipment, thereby improving operability in the mounting process. A segment for a tapered roller bearing is provided with a predetermined number of posts between a small-diameter-side end fringe which constitutes a small-diameter-side circumferential edge of a split type retainer and a large-diameter-side end fringe which constitutes a large-diameter-side circumferential edge thereof. Pockets are formed between the posts. At least the large-diameter-side end fringe, out of the small-diameter-side end fringe and the large-diameter-side end fringe, is provided with a large-diameter-side engagement piece. When the bearing is mounted, the large-diameter-side engagement piece is engaged with the large-diameter engagement member fitted and fixed onto the bearing's inner ring, whereby the segment is prevented from breaking up.
