Abstract
The present invention relates to a machine core of tower clocks with two or three hands. In the present invention, an hour hand shaft (3) and an hour wheel (4) are sheathed on a minute hand shaft (2) through a bearing (7); a minute wheel (6) is provided with a planet wheel (5) which is not coaxial with the minute wheel (6) and is sheathed on the minute wheel (6) through the bearing (7); one end of the planet wheel (5) is engaged with a fixed gear (9), and the other end of the planet wheel (5) is engaged with the hour wheel (4). The present invention adopts planet gear differential transmission for ensuring that a driving shaft and a driven shaft are coaxial and are in the same direction; the whole machine core has the advantages of compact structure and large bearing capacity; a second hand wheel can singly rotate and can be singly adjusted; the adjustment of clocks and hand driving have high speed and can be finished within two minutes, and mechanical wear is effectively reduced; simultaneously, the minute hand shaft, the hour hand shaft and a second hand shaft are controlled by the same set of control system for ensuring time traveling precision.
Description
Technical field the present invention relates to a kind of Machine core of turret clock, comprises two-hand tower clock cassette mechanism and three-hand tower clock cassette mechanism.
Hour hand axle, minute hand shaft and the second hand axle of existing two pins of background technology or three-hand tower clock cassette mechanism 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.
Summary of the invention the purpose of this invention is to provide a kind of two pin three-hand tower clock cassette mechanisms 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 present invention has adopted following technical scheme:
A kind of two pin three-hand tower clock cassette mechanisms comprise casing, minute hand shaft, and hour hand axle, the minute wheel that fixes with minute hand shaft is with the hour wheel of hour hand axle one.Hour hand axle is 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 its end is meshed with fixed gear, and the other end is meshed with hour wheel, and wherein fixed gear is fixed on the casing.
In order to realize this purpose better, the present invention also comprises second hand axle, and with the fixing second hand wheel of second hand axle, minute hand shaft is contained on the second hand axle by bearing holder (housing, cover), second hand wheel is fixed on the rear end of second hand axle, second hand wheel can rotate separately.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 present invention has following characteristics: (1), owing to adopted the planetary gear differential transmission, guaranteed minute hand shaft and hour hand axle coaxial, rotate in the same way, whole cassette mechanism structure compactness, bearing capacity is big.(2), 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.(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 the structural representation of two-hand tower clock cassette mechanism among the present invention.
Fig. 2 is the structural representation of three-hand tower clock cassette mechanism among the present invention.
Embodiment as shown in Figure 1, the minute hand shaft of two-hand tower clock cassette mechanism of the present invention 2 is fixedlyed connected with minute wheel 6 by split axle flat key 8.Hour hand axle 3 is structure as a whole with hour wheel 4, and they pass through bearing 7 integral assemblings on minute hand shaft 2.
Fixed gear 9 is fixed on the casing 1.Planetary gear 5 is sleeved on the minute wheel 6 by bearing 7, and is free to rotate.Its end is meshed with fixed gear 9, and the other end is meshed with hour wheel 4.Because hour wheel 4 is different with the number of teeth of fixed gear 9, when minute wheel 6 rotates, drive planetary gear 5 under motor-driven around the rotation of minute wheel 6 axle center.Simultaneously, be meshed and rotation with fixed gear 9 owing to planetary gear 5.The rotation of planetary gear 5 has driven hour wheel 4 and minute wheel 6 coaxial, differential rotations in the same way.
As shown in Figure 2, three-hand tower clock cassette mechanism of the present invention comprises casing 1, minute hand shaft 2, hour hand axle 3, second hand axle 10, the minute wheel 6 that fixes with minute hand shaft 2, with the hour wheel 4 of hour hand axle 3 one and with the fixing second hand wheel 11 of second hand axle 10.Described minute hand shaft 2 is sleeved on the second hand axle 10 by bearing 7, and second hand wheel 11 is fixed on the rear end of second hand axle 10, and second hand wheel 11 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.
Fixed gear 9 is fixed on the casing 1.Planetary gear 5 is sleeved on the minute wheel 6 by bearing 7, and is free to rotate.Its end is meshed with fixed gear 9, and the other end is meshed with hour wheel 4.Because hour wheel 4 is different with the number of teeth of fixed gear 9, when minute wheel 6 rotates, drive planetary gear 5 under motor-driven around the rotation of minute wheel 6 axle center.Simultaneously, be meshed and rotation with fixed gear 9 owing to planetary gear 5.The rotation of planetary gear 5 has driven hour wheel 4 and minute wheel 6 coaxial, differential rotations in the same way.Second hand wheel 11 then rotates separately under another motor-driven.In order to guarantee timekeeping performance, divide hour hand axle and second hand axle to control simultaneously with same set of control system.
