COAXIAL DISENGAGEABLE WHEELS FOR A TIMEPIECE MOVEMENT |
| 摘要 |
Device with coaxial disengageable wheels for a timepiece movement including an input wheel, an output wheel, a hub, and a jumper mechanism including a spring and positioning elements defining a certain number of discrete angular positions of the input wheel with respect to the output wheel around an axis of rotation. The positioning elements including hollow elements and protruding elements, the spring being configured to apply an elastic force pushing the protruding elements against the hollow elements to couple the wheels to each other below a disengagement torque. The protruding elements and the hollow elements extend in the axial direction and the spring is configured to apply an elastic force in the axial direction. |

1. A mechanism with coaxial disengageable wheels for a timepiece movement including an input wheel, an output wheel, a hub, and a jumper mechanism including a spring and positioning elements defining a certain number of discrete angular positions of the input wheel with respect to the output wheel around an axis of rotation, the axis of rotation defining an axial direction, the positioning elements including hollow elements and protruding elements, the spring being configured to apply an elastic force pushing the protruding elements against the hollow elements to couple the wheels to each other below an disengagement torque, wherein the protruding elements and the hollow elements extend in the axial direction and the spring is configured to apply an elastic force in the axial direction. |
