Description
Technical field the utility model relates to a kind of Machine core of turret clock of new structure, particularly a kind of three pins of new structure (hour hands, minute hand, second hand) Machine core of turret clock.
The existing three-hand tower clock cassette mechanism of background technology, two motors of every general employing of movement are used as power, and wherein a motor is used to drive the second hand axle rotation, and another motor via reducer structure drives minute hand shaft and hour hand axle rotates.The Machine core of turret clock of this structure has the following disadvantages at least: the first, because use two cover motors, two overlap control system, so volume is big, heaviness, manufacturing cost height.The second, second hand axle and branch, hour hand axle do not link, and second hand is difficult to guarantee coordination with dividing the hour hands rotation.
Utility model content the utility model aims to provide a kind of three-hand tower clock cassette mechanism, to overcome the defective of above-mentioned existing procucts.Technical matters to be solved is, by motor-driven second, branch, hour hand axle interlock, realizes three pin coordination operations.
The technical scheme that its technical matters that solves the utility model adopts is as follows:
A kind of three-hand tower clock cassette mechanism, gear train is installed in the housing, the inner gear train that is connected in the housing of coaxial hour hand axle, minute hand shaft and second hand axle, it is characterized in that: the output terminal of stepper motor connects the input end of worm screw, the worm gear supporting with worm screw is connected with worm-wheel shaft, and the output terminal of worm-wheel shaft connects the rear end of second hand axle; The output terminal and the third wheel of worm-wheel shaft are in transmission connection, and third wheel connected wheel shaft, and the output terminal of crossing wheel shaft is connected with dividing gear drive, divides gear to connect minute hand shaft; Minute hand shaft middle part is in transmission connection with back gear, and back gear is connected with minute wheel pivot, the output terminal of minute wheel pivot with the time gear drive be connected, the time gear connection hour hand axle.
The output terminal of worm-wheel shaft is connected with a joggle by tooth and the third wheel that is arranged on the worm-wheel shaft.
Cross the output terminal band tooth of wheel shaft, this tooth is connected with the branch gearing mesh,
Minute hand shaft middle part band tooth, this tooth is meshed with back gear.
The output terminal band tooth of minute wheel pivot, this tooth with the time gear be meshed.
The utlity model has following good effect: under (1), the step motor drive,, realized the interlock of three pins, coordination operation by the transmission of power and the speed adjustment of gear train.(2), its whole structure compactness, in light weight, take up an area of fewly, manufacturing cost is controlled.(3), running steadily, maintenance rate is low, long service life.
Description of drawings Fig. 1 is a structural representation of the present utility model.
Embodiment as shown in Figure 1, stepper motor 10 of the present utility model is installed in the outside, rear end of housing 4, gear train is installed in the housing 4, coaxial hour hand axle 3, minute hand shaft 2 and the second hand axle 1 inner gear train that is connected in the housing 4, and the outer end is positioned at outside the housing 4.
The output terminal of stepper motor 10 connects the input end of worm screw 9, and the worm gear 8 supporting with worm screw 9 is connected with worm-wheel shaft 7 by flat key, and the output terminal of worm-wheel shaft 7 is connected the rear end of second hand axle 1 by flat key and sleeve 15.When stepper motor 10 rotates, drive worm-wheel shaft 7 rotations, and then drive second hand axle 1 rotation by worm-and-wheel gear.
