Description
Technical field
The utility model relates to a kind of watch displays mechanism, when particularly relating to a kind of wrist-watch, minute hand planet display gear train.
Background technology
In today that science and technology is highly developed, stem-winder is no longer single persond eixis instrument, and is more by consumer is had as a kind of ornaments.Therefore, in order to win the market, attractive in appearance, novelty becomes the target that watch design person competitively pursue, and the movement of various style is also competitively come on stage thereupon, and wherein having unique movement indication mechanism is one wherein.
Publication number be CH692257A5 patent discloses a kind of timing display device, as shown in Figure 1: this indication mechanism adopt be planetary transmission structure, that is: disk M with 60 points/turn clockwise direction's uniform rotation, its effect is equivalent to minute hand; Hour hands are equipped with meanwhile, the little hour indicator H on disk M and the little hour wheel A of little hour wheel A() also rotate clockwise around the center of disk M thereupon, namely revolve round the sun.Meanwhile, little hour wheel A then drives hour hands to complete the deixis of hour hands around the center rotating of little hour indicator H with the 12 hours/clockwise direction that turns relative to little hour indicator H, and during upper 12 of little hour indicator H, the position of symbol remains upward during this period.Specifically: this mechanism is by base plate C, pipe core CC, rotating disk P, disk M, two planet gyration axle TR, planetary gear R1, R2, dead center wheel F, little hour wheel A, hour plate wheel D, little hour indicator H forms, its principle of work is: movement motion passes to by minute wheel the disk M pressed together with it, disk M is turned clockwise with the speed (60 points/turn) same with minute wheel, disk M is connected as one by axle TR and disk P, and drive disk P to rotate around pipe core CC with identical speed, thus drive planet wheel R1 and planet wheel R2 respectively around two planet gyration axle TR rotation, simultaneously around dead center wheel F revolution.Meanwhile; planetary gear R1 drives hour plate wheel D be engaged with rotate counterclockwise around the rotating shaft G be fixed on rotating disk P thus drive the little hour indicator H pressed together with D to rotate counterclockwise, and then eliminates owing to according with the angle departing from origin-location when P rotates clockwise the little hour indicator 12 caused; Planet wheel R2 drives the little hour wheel A be engaged with to turn clockwise around G axle, and little hour wheel studs with hour hands, and hour hands turn clockwise thereupon.
As can be seen from Fig. 1, although the structure of this kind of timing indication mechanism is simpler, but, this disk M to be directly fixed on minute wheel, the transmission mode of disk M is directly driven by minute wheel, make the moment of resistance suffered by minute wheel larger, this transmission mode adopts for the main transmission shown in Fig. 2 and passes motion to minute wheel thus the structure of drive index system by minute wheel sheet by friction mode, easily cause friction transmission failure, that is: the train that moves through of movement passes to minute wheel sheet, and be directly fixed on minute wheel due to disk M, when disk M being equipped with other parts, the overall deviation of gravity center of the disk M centre of gyration of minute wheel can be made, when movement is in " upper " or " under " position, this moment of resistance due to centre-of gravity shift generation drives the minute wheel sector-meeting of minute wheel to produce very large burden for relying on frictional fit, even likely occur that minute wheel sheet can not drive minute wheel to rotate, namely rub transmission failure.
Specifically: as shown in Figure 2, timepiece movement usually adopt time minute hand Presentation Function transmission form be: movement moves through train engaged transmission and passes to three tooth axles 1 ', thus drives the minute wheel sheet 2 ' engaged with three tooth axles 1 ' to rotate with the clockwise direction of 60 points/turns; Minute wheel sheet 2 ' is fitted on minute wheel 3 ' in the mode of frictional fit, thus drives minute wheel 3 ' to rotate with identical speed; Minute wheel 3 ' drives the back gear sheet 4 ' be engaged with to rotate counterclockwise, back gear sheet 4 ' drives pressing to be with it overall rotating across tooth axle 5 ', drive the hour wheel 6 ' be engaged with to rotate with the clockwise direction of 12 hours/turns across tooth axle 5 ', minute wheel 3 ', hour wheel 6 ' are equipped with minute hand, hour hands respectively, thus complete time indicating function.Due to frictional fit between minute wheel sheet and minute wheel, when the moment of resistance suffered by minute wheel is greater than the moment of friction between minute wheel sheet and minute wheel, minute wheel sheet just can not drive minute wheel to rotate, thus makes follow-up driving-chain fracture.
