Fig. 2 is table body internal structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Fig. 1 to 2, a kind of simple pointer wrist-watch that the present invention proposes, comprising: table body, the bottom of table intracoelomic cavity is provided with drive unit 1, the transmission device being connected with this drive unit. Also comprise the dial plate of being located at transmission device top, hour hands dial 3 and minute hand dial 2 that dial plate is arranged by inside and outside two circles form. The minute hand dial 2 of outer ring is annular, is fixedly connected with table body; The scale of hour hands dial 3 is within 12 hours, to set up to put, and hour hands dial 3 is with being located in the inner circle of minute hand dial 2 and being connected with transmission joint. One pointer 4 is located at the top of dial plate by a driven shaft 10, this driven shaft 10 is with the coaxial installation of hour hands dial 3 and be connected with transmission device. Pointer 4 is two ends end to end, and backshank is shorter than syringe needle, and syringe needle is that minute hand points to minute hand dial 2 and shows minute, and backshank is that hour hands point to hour hands dial 3 read clocks. Pointer 4 rotating 360 degrees per hour, and with syringe needle minute hand instruction minute, 330 ° of hour hands dial 3 rotations per hour, the instant asynchronous rotation of following backshank hour hands of drypoint scale 3 shows hour, time showing is very accurate.
As shown in Figure 2, in embodiments of the invention, transmission device comprises: the driving shaft 5 being connected with drive unit 1, be located at the first gear 6, the second gear 7 on this driving shaft 5, that engage with the first gear 6 and be fixedly connected on the 3rd gear 8 on a driven shaft 10, the 4th gear 9 engaging with the second gear 7 and be coaxially fixed on hour hands dial 3 belows. In the present embodiment, the hour hands dial 3 outwardly formation boss in bottom surface, boss cylindrical is provided with the 4th gear 9 engaging with the second gear 7, instant drypoint scale 3 itself is provided with the 4th gear 9, the coaxial kink of hour hands dial 3 is in the periphery of driven shaft 10, form matched in clearance with driven shaft 10, pointer 4 is fixedly connected on the top of driven shaft 10.
Specific works principle is as follows, drive unit 1 output speed is the rotating speed of driving shaft 5, driving shaft 5 drives the first gear 6 and the second gear 7 that are fixedly connected with it to rotate, therefore two-wheeled is identical with the angular speed of driving shaft 5, transmission is divided into two-way: the first via, steering needle 4 rotating speeds, drive the 3rd gear 8 engaging with it to rotate by the first gear 6, the 3rd gear 8 drives the driven shaft 10 being fixedly connected with it to rotate, drive the pointer fixing with it 4 to rotate by driven shaft 10 again, the 3rd gear 8 is identical with pointer 4 rotational angular velocities; The second tunnel, the rotating speed of control hour hands dial 3, hour hands dial 3 kinks, in driven shaft 10 peripheries, drive the 4th gear 9 engaging with it to rotate by the second gear 7, and instant drypoint scale 3 rotates. Make the first gear 6, the second gear 7, the 3rd gear 8, the 4th gear 9 numbers of teeth be respectively Z1, Z2, Z3, Z4. Due to pointer 4 rotating 360 degrees per hour, 330 ° of hour hands dial 3 rotations per hour, gearratio i34=i31*i24=(w3/w1) * (w2/w4)=(Z1/Z3) * (Z4/Z2)=12/11, the product of the gear ratio of the gear ratio of the first gear 6, the 3rd gear 8 and the 4th gear 9, the second gear 7 is 12/11, because the first gear 6 engages with the 3rd gear 8, the second gear 7 engages with the 4th gear 9, and the first gear 6, the second gear 7 are located on driving shaft 5, the 3rd gear 8 and the 4th gear 9 coaxially arrange, and the centre-to-centre spacing between the centre-to-centre spacing between the first gear 6, the 3rd gear 8 and the second gear 7, the 4th gear 9 equates. Reset rotating speed and gearratio i that drive unit 1 is exported31Product, makes pointer 4 rotating 360 degrees per hour, sets rotating speed and gearratio i that drive unit 1 is exported24Product, makes 330 ° of hour hands dial 3 rotations per hour.
In first embodiment of the invention, set the first gear 6 identical with the 3rd gear 8 numbers of teeth, the gear ratio of the second gear 7 and the 4th gear 9 is 11/12, and the rotating speed that setting drive unit 1 is exported is 360 °/hour, and the rotating speed of driving shaft 5 is also 360 °/hour. For example, in the time that the first gear 6 and the 3rd gear 8 numbers of teeth are all set to 23, second gear 7 numbers of teeth are that 22, the four gear 9 numbers of teeth are 24, meet operation principle, ensure pointer 4 rotating 360 degrees per hour, 330 ° of hour hands dial 3 rotations per hour.
In second embodiment of the invention, the gear ratio of setting the first gear 6 and the 3rd gear 8 is the gear ratio 11/3 of 4, the second gears 7 and the 4th gear 9, and setting drive unit 1 output speed is half-twist per hour, and the rotating speed of driving shaft 5 is also 360 °/hour. For example, be 110 o'clock when first gear 6 numbers of teeth are set to 30, the three gear 8 numbers of teeth, second gear 7 numbers of teeth are that 112, the four gear 9 numbers of teeth are 28, meet operation principle, ensure pointer 4 rotating 360 degrees per hour, 330 ° of hour hands dial 3 rotations per hour.
In third embodiment of the invention, the gear ratio of setting the first gear 6 and the 3rd gear 8 is 12/11, the second gear 7 is identical with the 4th gear 9 numbers of teeth, and setting drive unit 1 output speed is 330 ° of rotations per hour, and the rotating speed of driving shaft 5 is also 330 °/hour. For example, it is that 22, the second gears 7 and the 4th gear 9 numbers of teeth are set to 23 that first gear 6 numbers of teeth are set to 24, the three gear numbers of teeth, meets operation principle, ensures pointer 4 rotating 360 degrees per hour, 330 ° of hour hands dial 3 rotations per hour.
According to above-described embodiment, can also draw, if pointer 4 rotation per hour n × 360 °,: hour hands dial 3 rotation per hour: n × 360 °-360 °/(12*n), wherein, n value ensure 360 °/(12*n) be rational, this rational does not comprise Infinite Cyclic decimal. According to the rotation speed relation between pointer 4 and hour hands dial 3, set the output speed of drive unit 1, the gearratio of transmission device, can reach the requirement of accurate displaying time.
Above specific embodiment is only in order to illustrate structure of the present invention, and those of ordinary skill in the art can make various deformation and variation under design of the present invention, and these distortion and variation include within protection scope of the present invention.
