Roller type one-way clutch and roller for the roller type one-way clutch

摘要

A roller type one-way clutch comprising an outer ring and an inner ring radially spaced apart from each other and disposed concentrically with each other for rotation relative to each other, the outer ring having an axially extending annular inner peripheral cam surface, the inner ring being disposed in the outer ring and having an annular outer peripheral raceway surface, and a plurality of rollers disposed between the outer ring and the inner ring for transmitting torque between the outer peripheral raceway surface and the inner peripheral cam surface is characterized in that the rolling surface of each of the rollers has a recess depressed toward the axis thereof over the entire circumference thereof. Also, a roller type one-way clutch comprising an outer ring and an inner ring radially spaced apart from each other and disposed concentrically with each other for rotation relative to each other, the outer ring having an axially extending annular inner peripheral raceway surface, the inner ring being disposed in the outer ring and having an annular outer peripheral cam surface, and a plurality of rollers disposed between the outer ring and inner ring for transmitting torque between the inner peripheral raceway surface and the outer peripheral cam surface is characterized in that the rolling surface of each of the rollers has a recess depressed toward the axis thereof over the entire circumference thereof.
