Title:
EXTRACTION STRUCTURE OF CONICAL ROLLER BEARING
Document Type and Number:
Japanese Patent JP2015194216
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an extraction structure of a conical roller bearing which can smoothly extract the conical roller bearing which is fit and fixed to a housing from the housing by simple means.SOLUTION: An extraction structure for extracting a conical roller bearing 1 in which an external periphery of an outer ring 3 is fit and fixed to a hub 7 being a housing from the hub 7 is constituted of the hub 7 and an extraction jig 8, the hub 7 has a notched part 7d for exposing an end face 3c from the hub 7 at a part of a region which abuts on the end face 3c of the outer ring 3, the extraction jig 8 has a pressing region 8b which is a region penetrating the notched part 7d from the outside of the hub 7, abuts and presses on the exposed end face 3c of the outer ring 3 at the extraction, and has a shape not abutting on a region other than the end face 3c of the outer ring 3, and the conical roller bearing 1 is extracted from the hub 7 by pressing only the end face 3c of the outer ring 3 by a pressing region 8b of the extraction jig 8 at the extraction.
