Title:
POWER TRANSMISSION ROLLER
Document Type and Number:
Japanese Patent JP2016128699
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To stably transmit power by friction between a driving roller D and a driven roller S, and to make a power transmission mechanism therefor compact.SOLUTION: There is constituted a power transmission roller that comprises a bearing 2 which has an outer ring 2a and an inner ring 2b made relatively rotatable with rolling elements 2d interposed between the inner and outer rings 2a, 2b, a retaining member 3 provided on an inner diameter side of the inner ring 2b with a gap left with the inner diameter side, a first energizing member 4 interposed between the inner diameter side of the inner ring 2b and the retaining member 3, and a second energizing member 5 interposed between the inner diameter side of the inner ring 2b and the retaining member 3 and differing in energizing force from the first energizing member 4, and displaces the retaining member 3 with respect to the bearing 2 against energizing force of the first energizing member 4 and second energizing member 5 with external force operating on the side of the outer ring 2a as the driving roller D and driven roller S abuts on each other.SELECTED DRAWING: Figure 1
