Description
Technical field
The present invention relates to a kind of watch displays mechanism, during more particularly to a kind of wrist-watch, minute hand planet show transmission mechanism.
Background technology
In scientific and technical highly developed today, stem-winder has no longer been single persond eixis instrument, and is more
Possessed as a kind of ornaments by consumer.Therefore, it is attractive in appearance, novel competitively to be chased after as watch design person in order to win the market
The target asked, the movement of various styles are also competitively come on stage therewith, wherein being therein one with unique movement indication mechanism
Kind.
The A5 of Publication No. CH 692257 patent discloses a kind of timing display device, as shown in Figure 1：The indication mechanism
Using planetary transmission structure, i.e.,：For disk M with 60 points/turns of clockwise direction's uniform rotation, it functions as minute hand；
At the same time, the hour disk H on disk M and small hour wheel A（Hour hands are housed on small hour wheel A）Also surround and be in a good mood in disk M therewith
Hour hands rotate, that is, revolve round the sun.At the same time, small hour wheel A then drives hour hands relative to hour disk H with the speed up time of 12 hours/turns
Pin completes the indicator function of hour hands around hour disk H center rotating, and the position accorded with when hour disk H is upper 12 during this period is all the time
Keep upward.Specifically：This mechanism is by bottom plate C, central tube CC, rotating disk P, disk M, two planet gyration axle TR, planetary gears
R1, R2, fixed center wheel F, small hour wheel A, hour plate wheel D, hour disk H compositions, its operation principle are：Movement motion is passed by minute wheel
The disk M pressed together with it is passed, makes disk M with the speed same with minute wheel（60 points/turn）Turn clockwise, disk M
Connected as one by axle TR and disk P, and drive disk P to be rotated with same speed around central tube CC, so as to drive row
Star gear R1 and planetary gear R2 surrounds two planet gyration axle TR rotations respectively, while is revolved round the sun around fixed center wheel F.With this
Meanwhile the rotating shaft G that planetary gear R1 drives the hour plate wheel D being engaged with to be secured around on rotating disk P is rotated counterclockwise so as to band
During 12, hour disk caused by the dynamic hour disk H pressed together with D is rotated counterclockwise, and then elimination is rotated clockwise due to P
Symbol deviates the angle of origin-location;Planetary gear R2 drives the small hour wheel A being engaged with to be turned clockwise around G axles, small hour wheel
On stud with hour hands, hour hands turn clockwise therewith.
As can be seen that although the structure of such a timing indication mechanism is simpler from Fig. 1, it is this that disk M is direct
It is fixed on minute wheel, disk M transmission means is directly driven by minute wheel so that the moment of resistance is larger suffered by minute wheel, this transmission side
Formula uses for the main transmission shown in Fig. 2 and passes motion to minute wheel by friction mode so as to drive index system by minute wheel piece
Structure, easily cause friction transmission failure, i.e.,：The motion of movement passes to minute wheel piece by train, and because disk M is straight
Connect and be fixed on minute wheel, when being equipped with other parts on disk M, the disk M overall deviation of gravity center revolution of minute wheel can be made
Center, it is this because the moment of resistance caused by centre-of gravity shift is for by rubbing when movement is in " upper " or during " under " position
Coordinate the minute wheel sector-meeting for driving minute wheel to produce very big burden, minute wheel can not be driven to rotate it could even be possible to there is minute wheel piece, that is, rubbed
Wipe transmission failure.
Specifically：As shown in Fig. 2 timepiece movement generally use when minute hand display function transmission form be：Movement
Motion passes to three tooth axles 1 ' by train engaged transmission, so as to drive the minute wheel piece 2 ' engaged with three tooth axles 1 ' with 60 points/turns
Clockwise direction rotate；Minute wheel piece 2 ' is fitted on minute wheel 3 ' in a manner of frictional fit, so as to drive minute wheel 3 ' with identical
Speed rotation；Minute wheel 3 ' drives the back gear piece 4 ' being engaged with to rotate counterclockwise, and back gear piece 4 ' drives pressing therewith as entirety
Across tooth axle 5 ' rotate, across tooth axle 5 ' drives the hour wheel 6 ' being engaged with to be rotated with the 12 hours/clockwise direction that turns, minute wheel
3 ', minute hand, hour hands are respectively provided with hour wheel 6 ', so as to complete time indicating function.Due to being rubbed between minute wheel piece and minute wheel
Coordinate, when the moment of resistance suffered by minute wheel is more than the moment of friction between minute wheel piece and minute wheel, minute wheel piece cannot drive minute wheel
Rotation, so that follow-up driving-chain fracture.
The content of the invention
The technical problem to be solved by the invention is to provide one kind installation simply, minute wheel load is small and transmission is not easy to fail,
Minute hand planet shows transmission mechanism during movement energy loss small wrist-watch.
