Abstract (en)

[origin: US2018307183A1] Timepiece mechanism comprising a structure in which at least one arbor of a wheel set is pivoted about an axis of rotation, and comprising a braking device for the mechanical braking at constant torque of this arbor, the braking device comprises a braking component which is removable with respect to the structure and comprises, for attachment thereof to the structure, a solid felloe, which carries a plurality of resilient elements, regularly distributed around a common axis about which these resilient elements each have a contact area. the contact areas together defining an opening, arranged to engage, in a press fit with elastic gripping, with the arbor, to make the common axis coincide with the axis of rotation of the arbor, and to apply to the arbor a substantially constant tangential braking force.
