Description
Technical field
The utility model relates to a kind of top flywheel mechanism of mechanical watch, particularly relates to a kind of twin shaft top flywheel mechanism of mechanical watch.
Background technology
Top flywheel in the mechanical watch is a kind of device that reduces isochronal error; This apparatus features is that balance and hair spring system and escapement are placed in the framework; In self-operating, can also rotate with framework; Reduced to greatest extent because thereby the clock and watch site error that terrestrial gravitation caused has improved timekeeping performance; The device that overlaps with the rotation of framework of the axis of balance and hair spring system (referenced patent " wrist-watch coaxial-type rotation escapement the speed adjusting gear "-patent No.: 200720096902.5) be called " coaxial-type top flywheel " wherein; The shaft center line of the shaft center line and framework of balance and hair spring system self overlaps in top flywheel framework, therefore this kind top flywheel is called single shaft top flywheel.
A kind of can better the minimizing because thereby the site error that terrestrial gravitation caused further improves the twin shaft top flywheel of timekeeping performance appearred at present; Like twin shaft tandem top flywheel; This design feature is that the shaft center line of shaft center line and the outside framework that is connected bearing support of carrying the inner frame of balance and hair spring system is square crossing; And the ceaselessly conversion of the angle of the shaft center line of inner frame and movement axial line from 0 ° to 90 °, the shaft center line of outside framework perpendicular to the axial line of movement.
Existing twin shaft top flywheel such as CN patent publication No. 2036454A and US patent publication No. 18060147760A1 are twin shaft top flywheel.Wherein, publication number CN2036454A is the twin shaft tandem, and inner frame has adopted Breguet formula top flywheel mechanism, i.e. support pattern up and down, and the energy input mode is that the tooth axle through being arranged on the outside framework lower end cooperates with face gear on being fixed on clamping plate.The shortcoming of this structure is that wrist-watch thickness is bigger; Because the structure of top flywheel outside framework must be closed; The gauge of its general frame can be very big, and the energy input mode makes face gear be made into the very big annular gear wheel of size, has further increased the integral thickness of this movement.
