As shown in Figure 2, in embodiment of the present utility model, gearing comprises: the main drive shaft 5 being connected with drive unit 1, be located at the first gear 6, the second gear 7 on this main drive shaft 5, with the first gear 6 engagement and be fixedly connected on the 3rd gear 8 on a driven shaft 10, with the second gear the 4th gears 97 engagements and that be coaxially fixed on hour hands index dial 3 belows.In the present embodiment, the hour hands index dial 3 outwardly formation boss in bottom surface, boss cylindrical is provided with the 4th gear 9 with the second gear 7 engagements, instant drypoint scale 3 itself is provided with the 4th gear 9, the coaxial kink of hour hands index dial 3 is in the periphery of driven shaft 10, form clearance fit 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 main drive shaft 5, main drive 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 velocity of main drive shaft 5, transmission is divided into two-way: the first via, steering needle 4 rotating speeds, by the first gear 6, drive with the 3rd gear 8 of its engagement and rotate, the 3rd gear 8 drives the driven shaft 10 being fixedly connected with it to rotate, by driven shaft 10, drive the pointer fixing with it 4 to rotate again, the 3rd gear 8 is identical with pointer 4 rotational angular velocities; The second tunnel, the rotating speed of control hour hands index dial 3, hour hands index dial 3 kinks, in driven shaft 10 peripheries, are driven with the 4th gear 9 of its engagement and are rotated by the second gear 7, instant drypoint scale 3 rotations.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 index dial 3 rotations per hour, ratio of gear i
34=i
31* i
24=(w3/w1) * (Z4/Z2)=12/11 of * (w2/w4)=(Z1/Z3), 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, due to the first gear 6 and the 3rd gear 8 engagements, the second gear 7 and the 4th gear 9 engagements, and the first gear 6, the second gear 7 are located on main drive shaft 5, the 3rd gear 8 and the 4th gear 9 coaxially arrange, and the centre distance between the first gear 6, the 3rd gear 8 equates with the centre distance between the second gear 7, the 4th gear 9.Reset rotating speed and the ratio of gear i of drive unit 1 output
31product, makes pointer 4 rotating 360 degrees per hour, sets rotating speed and the ratio of gear i of drive unit 1 output
24product, makes 330 ° of hour hands index dial 3 rotations per hour.
In the utility model the first embodiment, 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 12/11, and the rotating speed of setting drive unit 1 output is 360 °/hour, and the rotating speed of main drive shaft 5 is also 360 °/hour.For example, when 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 principle of work, guarantee pointer 4 rotating 360 degrees per hour, 330 ° of hour hands index dial 3 rotations per hour.
In the utility model the second embodiment, the gear ratio of setting the first gear 6 and the 3rd gear 8 is 4, the gear ratio 3/11 of the second gear 7 and the 4th gear 9, setting drive unit 1 output speed is half-twist per hour, the rotating speed of main drive shaft 5 is also 360 °/hour.For example, when first gear 6 numbers of teeth are set to 30, the three gear 8 numbers of teeth, be 110 o'clock, second gear 7 numbers of teeth are that 28, the four gear 9 numbers of teeth are 112, meet principle of work, guarantee pointer 4 rotating 360 degrees per hour, 330 ° of hour hands index dial 3 rotations per hour.
In the utility model the 3rd embodiment, 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 main drive 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 principle of work, guarantees pointer 4 rotating 360 degrees per hour, 330 ° of hour hands index dial 3 rotations per hour.
According to above-described embodiment, can also draw, if pointer 4 rotation per hour n * 360 °,: hour hands index dial 3 rotation per hour: n * 360 °-360 °/(12*n), wherein, n value guarantee 360 °/(12*n) be rational number, this rational number does not comprise infinite loop decimal.According to the rotation speed relation between pointer 4 and hour hands index dial 3, set the output speed of drive unit 1, the ratio of gear of gearing can reach the requirement of accurate displaying time.
Above specific embodiment is only in order to illustrate structure of the present utility model, and those of ordinary skill in the art can make various deformation and variation under design of the present utility model, and these distortion and variation include within protection domain of the present utility model.
