Abstract
A horological mechanism (110), notably a horological movement or chronograph module, including a counting chain (100) having an epicycloidal train (31, 32, 33, 34) including a first sun wheel (33) fixed to the frame.
Claims23
A horological mechanism comprising:
- a frame, and
- a counting chain comprising an epicycloidal train including a planetary wheel gear and a first sun wheel,
- wherein the first sun wheel is fixed to the frame regardless of a stopped state or in-motion state of the counting chain,
- wherein the counting chain is linked kinematically to another counting chain.
1 more element
A method for mounting a mechanism or a timepiece, wherein the method comprises:
- providing a frame,
- mounting a driving mobile on the frame,
- mounting an hours counter on the frame, and
- mounting:
- (i) a mobile meshing with the driving mobile and with the hours counter, or
- (ii) an epicycloidal train meshing with the driving mobile and with the hours counter, the epicycloidal train including a planetary wheel gear and a first sun wheel,
- wherein the first sun wheel is fixed to the frame regardless of a stopped state or in-motion state of the hours counter,
- wherein the hours counter is linked kinematically to another counting chain.
5 more elements
A horological mechanism comprising:
- a frame, and
- a counting chain comprising an epicycloidal train including a planetary wheel gear and a first sun wheel,
- wherein the first sun wheel is fixed to the frame,
- wherein the clutch device comprises a vertical clutch mobile.
1 more element
A horological mechanism comprising:
- a frame, and
- a counting chain comprising an epicycloidal train including a planetary wheel gear and a first sun wheel,
- wherein the first sun wheel is fixed to the frame,
- wherein the epicycloidal train comprises a second sun wheel which is an output sun wheel of the epicycloidal train arranged so as to drive, by meshing, directly or indirectly, a counter of the counting chain,
- wherein the second sun wheel is arranged so as to drive, by meshing, directly or indirectly, an hour counter,
- wherein the hour counter is an hour counter performing one revolution every 24 hours.
3 more elements
A horological mechanism comprising:
- a frame, and
- a counting chain comprising an epicycloidal train including a planetary wheel gear and a first sun wheel,
- wherein the first sun wheel is fixed to the frame,
- wherein the mechanism comprises a driver finger driving the counting chain,
- wherein the horological mechanism comprises a clutch device comprising the driver finger driving the counting chain.
