Title:
FRICTION TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2023149491
Kind Code:
A
Abstract:
To provide a friction transmission device which can apply more stable pressing force.SOLUTION: A friction transmission device 100 of an embodiment includes: a planetary rolling element 20 disposed around a rotary shaft; a first bearing ring 30 and a second bearing ring 28 which contact with the planetary rolling element 20; and a pressing force application mechanism 7 which presses the second bearing ring 28 to generate a pressing force to a contact surface between the second bearing ring 28 and the planetary rolling element 20. A first bearing ring support part 36 which supports the first bearing ring 30 at the opposite side of the planetary rolling element 20, a contact surface 20d between the first bearing ring 30 and the planetary rolling element 20, a contact surface 20c between the second bearing ring 28 and the planetary rolling element 20, and a contact surface between the pressing force application mechanism 7 and the second bearing ring 28 overlap when viewed from an axial direction.SELECTED DRAWING: Figure 2
