Abstract (en)
[origin: CN204229119U] The utility model relates to a clock gear train with unidirectional gears. The clock gear train comprises a mandrel (80) carrying a small gear (81) and at least one first gear (82); the at least one first gear (82) and the small gear (81) are coaxial and are pivotally mounted on the mandrel (80); the first gear (82) is connected with the mandrel (80) through a first elastic rotation resetting mechanism forming a first uncoupling means (91) or at least one first spring (84), wherein the first uncoupling means applies friction to the first gear (82); and the gear train further comprises a second gear (86) which is pivotally mounted on the mandrel (80) and is connected with the mandrel (80) through a second elastic rotation resetting mechanism forming a second uncoupling means (92) or at least one second spring (88), wherein the second uncoupling means applies friction to the second gear (86). The utility model also relates a clock movement including the above clock gear train, and a clock including the clock movement.
