Above-mentioned existing standard machinery formula wrist-watch the time minute hand separating mechanism the course of work be:
When wrist-watch normally moved, minute wheel 1 rotated under the driving of basic movement main transmission, drove the minute hand (not shown) on the one hand and rotated, and indicated the number of minutes on the dial plate (not shown); On the other hand, drive back gear sheet 2 and stride tooth axle 3 and rotate, striding tooth axle 3 drive day-date hour wheels 4 and day-date wheel 5 rotates, day-date wheel 5 drives idle wheel 6 and rotates, idle wheel 6 drives a hour wheel 7 and rotates, hour wheel 7 drives the hour hands (not shown)s and rotates, and indicates hourage on the dial plate (not shown).
Above-mentioned standard machinery formula wrist-watch the time minute hand separating mechanism shortcoming be:
Existing from above standard machinery formula wrist-watch the time course of work of minute hand separating mechanism and Fig. 1 as can be seen, minute wheel 1 is various to hour transmission link of wheel 7, each all needs certain hour to the gear teeth of the power wheel backlash of passing by in transmission process, these accumulated times get up, and have just caused the serious hysteresis phenomenon of hour hands.Particularly after wrist-watch fell to dial pin, when wrist-watch reruned, this hysteresis phenomenon of hour hands was just even more serious, and can reach 20 minutes retardation time the longest.
Summary of the invention
Technical problem to be solved in the utility model is, overcome above-mentioned existing standard machinery formula wrist-watch the time minute hand separating mechanism shortcoming, a kind of time minute hand separating mechanism of eliminating wrist-watch hour hands hysteresis phenomenon is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the time minute hand separating mechanism that the utility model can be eliminated wrist-watch hour hands hysteresis phenomenon comprises: minute wheel, go up minute wheel, partially the back gear sheet, stride tooth axle and little hour wheel partially; The described minute wheel of going up forms coaxial integrative-structure with minute wheel; The described tooth axle of striding partially forms coaxial integrative-structure with inclined to one side back gear sheet; The described minute wheel of going up is meshed with inclined to one side back gear sheet, and the described tooth axle of striding partially is meshed with little hour wheel.
The described minute wheel of going up is pressed together on the minute wheel;
The described tooth axle riveted of striding partially is on inclined to one side back gear sheet;
According to integrally-built needs, the described minute wheel of going up can be pressed together on the minute wheel upper surface, also can be pressed together on the minute wheel lower surface.
The beneficial effects of the utility model are: simple in structure, be convenient to produce and assembling; Can eliminate wrist-watch hour hands hysteresis phenomenon effectively.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 3 and Figure 4, the utility model time minute hand separating mechanism that can eliminate wrist-watch hour hands hysteresis phenomenon comprises: minute wheel 1, go up minute wheel 8, partially back gear sheet 2 ', stride tooth axle 3 ' and hour wheel 7 ' partially; The described minute wheel 8 of going up is pressed together on the minute wheel 1, and the two forms coaxial integrative-structure; The described tooth axle 3 ' riveted of striding partially is on inclined to one side back gear sheet 2 ', and the two forms coaxial integrative-structure; The described minute wheel 8 of going up is meshed with inclined to one side back gear sheet 2 ', and the described tooth axle 3 ' of striding partially is meshed with a hour wheel 7 '.
According to integrally-built needs, the described minute wheel 8 of going up can be pressed together on minute wheel 1 upper surface, also can be pressed together on minute wheel 1 lower surface.
The utility model can eliminate wrist-watch hour hands hysteresis phenomenon the time minute hand separating mechanism the course of work be:
When wrist-watch normally moved, minute wheel 1 rotated under the driving of basic movement main transmission, drove the minute hand (not shown) on the one hand and rotated, and indicated the number of minutes on the dial plate (not shown); On the other hand, minute wheel 8 rotates thereupon together in the drive; Last minute wheel 8 drives inclined to one side back gear sheet 2 ' and rotates, stride tooth axle 3 ' partially rotates thereupon together, stride tooth axle a 3 ' drive hour wheel partially and rotate, hour wheel 7 ' drives the hour hands (not shown) and rotates, and indicates hourage on the dial plate (not shown).
From above the utility model can eliminate wrist-watch hour hands hysteresis phenomenon the time course of work of minute hand separating mechanism and Fig. 1 as can be seen, minute wheel 1 significantly reduces to a hour wheel transmission link of 7 ', thereby shortened in the transmission process each greatly the gear teeth of power wheel passed by time of backlash.Specifically, because the rotational speed of minute wheel 1 is 1 a hour/circle, the rotational speed of striding tooth axle 3 ' partially is 2.7 a hours/circle, makes hour hands be no more than 3.8 minutes retardation time, we can say the hysteresis phenomenon of having eliminated the wrist-watch hour hands basically.
