Title:
ASSEMBLING METHOD OF ROLLING BEARING AND ROLLING BEARING
Document Type and Number:
Japanese Patent JP2016008662
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an assembling method of a rolling bearing which can easily fit rolling bodies to pockets of a crown-shaped cage without causing breakage without the need for applying humidity conditioning (humidification) treatment and a softening material to a material before injection molding, and the rolling bearing.SOLUTION: A rolling bearing has inner rings 3, 13, outer rings 4, a plurality of rolling bodies 5 and a cage 30. The cage is molded of a resin material having a hydroscopic property, and has a ring part and a crown shape in which a plurality of pockets are denied to which the rolling bodies are fit by a plurality of column parts which are extended to an axial direction from the ring part. An assembling method of the rolling bearing includes a heating process for heating the cage to a temperature not lower than a glass transition point of the resin material, and an assembling process for assembling the rolling bodies to the cage which is heated to the temperature not lower than the glass transition point.
