Abstract
The utility model discloses a movement of three-hand set turret clock, wherein, a minute shaft(4) is bell socketed on a second hand shaft (3) via a bearing (2); a second hand wheel (9) which can turn independently is fixed on the rear end of the second hand shaft (3). On one hand, as the second hand wheel (9) can turn independently, so the minute hand, hour hand and second hand can be adjusted respectively when the clock is adjusted, and the whole process takes at most 2 minutes to finish, thereby being very quick and reducing effectively the wearing of the device. Meanwhile, time-sharing hand shaft and the second hand shaft are controlled by the same control system, thereby ensuring the accuracy of the clock. On the other hand, planetary gear differential drive is adopted to ensure the coaxial drive of a drive shaft and a driven shaft in the same direction. The whole movement is compact in structure and great in carrying capacity.
Description
Technical field the utility model relates to a kind of Machine core of turret clock, particularly a kind of three-hand tower clock cassette mechanism.
The hour hand axle of the existing three-hand tower clock cassette mechanism of background technology, minute hand shaft and second hand axle must rotate when work in the same way, and the gear drive of adopting is dead axle transmission usually.Therefore cause machine volume huge, the generation of problems such as inner structure complexity, not only cost is higher, and noise is big, maintenance inconvenience.On the other hand, when transferring clock to catch up with pin, the revolution of second hand axle is 60 times of hour hand axles, not only waste time and energy, and the second hand axle wearing and tearing is too serious.
Utility model content the purpose of this utility model provides a kind of three-hand tower clock cassette mechanism of new structure, by of coaxial, the in the same way rotation of planet differential transmission realization hour hands with minute hand, second hand, and realize the driving respectively of second hand axle and branch, hour hand axle, in order to overcome the defective of above-mentioned existing procucts.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of three-hand tower clock cassette mechanism, comprise casing, minute hand shaft, hour hand axle, second hand axle, the minute wheel that fixes with minute hand shaft, with the hour wheel of hour hand axle one and the second hand wheel of fixing with second hand axle, minute hand shaft is contained on the second hand axle by bearing holder (housing, cover), and second hand wheel is fixed on the rear end of second hand axle, and second hand wheel can rotate separately.
In order to realize this purpose better, hour hand axle and hour wheel are contained on the minute hand shaft by bearing holder (housing, cover); Planetary gear is installed on the minute wheel, this planetary gear and minute wheel disalignment, it is contained on the minute wheel by bearing holder (housing, cover) and is meshed with fixed gear on being fixed on casing.Wherein, minute hand shaft is fixedlyed connected by the split axle flat key with minute wheel; Second hand axle is fixedlyed connected by a second axle flat key with second hand wheel.
The utlity model has following characteristics: (1), because the second hand wheel individual drive, when transferring clock second hand and the time minute hand can adjust respectively, so transfer clock to catch up with needle speed fast, can finish, and reduce mechanical wear effectively in the longest 2 minutes.Simultaneously, divide hour hand axle and second hand axle to control, guaranteed timekeeping performance with same set of control system.(2), owing to adopted the planetary gear differential transmission, guaranteed main drive shaft and driven shaft coaxial, rotate in the same way, whole cassette mechanism structure compactness, bearing capacity is big.(3), global design is scientific and reasonable, be skillfully constructed.(4), small product size is little, it is little to take up room, noise is low, and is stable, easy to maintenance.
Description of drawings Fig. 1 is a structural representation of the present utility model.
Embodiment as shown in Figure 1, the utility model comprises casing 1, minute hand shaft 4, hour hand axle 5, second hand axle 3, the minute wheel 8 that fixes with minute hand shaft 4, with the hour wheel 6 of hour hand axle 5 one and the second hand wheel of fixing with second hand axle 39, described minute hand shaft 4 is sleeved on the second hand axle 3 by bearing 2, and second hand wheel 9 is fixed on the rear end of second hand axle 3, and second hand wheel 9 can rotate separately under motor-driven.Divide hour hand axle and second hand axle to control, to guarantee timekeeping performance with same set of control system.
Minute hand shaft 4 of the present utility model is fixedlyed connected with minute wheel 8 by split axle flat key 10.Hour hand axle 5 is structure as a whole with hour wheel 6, and they pass through bearing 2 integral assemblings on minute hand shaft 4.Second hand axle 3 is fixedlyed connected by a second axle flat key 11 with second hand wheel 9.
Fixed gear 12 of the present utility model is fixed on the casing 1.Planetary gear 7 is sleeved on the minute wheel 8 by bearing 2, and is free to rotate.Its end is meshed with fixed gear 12, and the other end is meshed with hour wheel 6.Because hour wheel 6 is different with the number of teeth of fixed gear 12, when minute wheel 8 rotates, drive planetary gear 7 under motor-driven around the rotation of minute wheel 8 axle center.Simultaneously, be meshed and rotation with fixed gear 12 owing to planetary gear 7.The rotation of planetary gear 7 has driven hour wheel 6 and minute wheel 8 coaxial, differential rotations in the same way.
