Title:
ROTARY BEARING COOLING STRUCTURE, DEVELOPING DEVICE, IMAGE FORMING DEVICE, AND ROTARY BEARING STRUCTURE
Document Type and Number:
Japanese Patent JP2016006344
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To efficiently cool a bearing of a rotary member in a device including the rotary member.SOLUTION: A rotary bearing cooling structure for cooling a bearing of a rotary member includes a bearing 60 rotatably supporting a shaft of a stirring conveying member 55Ya, and a retaining ring 100 disposed on an end side of the shaft with respect to the bearing 60, and restricting axial movement of the stirring conveying member 55Ya. The retaining ring 100 has a blade portion 103 generating air flow by rotating in accompany with rotation of the stirring conveying member 55Ya, and the air flow generated by the rotation of the retaining ring 100, passes through a space facing the bearing 60.
