Abstract

PURPOSE:To allow the smoother movement of the second hand by correcting the wheel train on a slip mechanism side of the side nearer a driven wheel than the slip mechanism and from the driven wheel by a correcting lever at the time of hand setting. CONSTITUTION:The correcting lever 19 corrects an intermediate wheel 7 and comes into contact with the resetting part of a circuit block simultaneously therewith, thereby stopping the emission of driving pulses from an IC and stopping a rotor 4 at the time of hand setting. The driven wheel 6b can be rotated at a constant speed immediately when the correction is released in this state. A conversion wheel 6 and an oil rotor 8 are deviated from the center of the timepiece body and are flatly laid out via the intermediate body in this embodiment. The spring constant is, therefore, decreased and the fluctuation in the recovering force of a main driving wheel 6a is decreased by increasing the length of a hair spring 6c, by which the rotor 8 can be rotated at the constant speed. The fluctuation in load by the inclination, etc., of a rotor plate 8c, cavity 13, cap 14, is decreased by increasing the size of an oil rotor plate 8c. The smoother movement of the second hand 10 is thus assured.

[Problems to be Solved by the Invention] However, the conventional second hand regulation device has a driving side regulation spring, a driven side regulation spring, and a lever guide part, and also,
Parts and the like are required to operate both at the same time, which not only makes the structure quite complex, but also increases the number of parts. Furthermore, since the mechanism for converting step drive into sweep drive and the second hand regulating device are concentrated in the center of the four-cut design, it is impossible to make the watch thinner. In addition, if the two regulating springs are not regulated at the same time, a phase difference will occur between the driving side and the driven side, and a smooth start will not be possible when the regulation is released. Furthermore, since the mechanism that converts step drive to sweep drive must be small, the restoring force and load fluctuate greatly even with slight variations in parts, making it difficult to maintain clear movement of the second hand. The driven-side regulating spring regulates the following magnet, but there is a problem in that cracking or chipping occurs when force is applied to the magnet. As explained above, this structure has the drawback of cracking the magnet, is not only expensive in terms of the number of parts and precision of parts, but also impossible to make into a thin watch, and when regulations are lifted. It is difficult to get a smooth start, and it is also difficult to make the movement of the second hand clear.

The intermediate wheel 7 meshes with the driven wheel 6b, the oil rotor ring 8a, and the fourth gear 9. A second hand 10 is fixed to the fourth wheel 9, and a minute hand 12 is fixed to the fifth wheel 11. The fifth wheel J1 consists of a second pinion lla and a second gear 11b, which slip when a certain amount of torque is applied to each other. The fourth ratio 9 rotates at irpm, and the reduction ratio of the oil rotor kana 8a and the fourth @9 is 2.1, so the rotation speed of the oil rotor 8 is 2.1. lrpm. Since the rotational speed of the rotor 4 is 12 Or p m, the reduction ratio between the rotor tie and the oil rotor 8 is approximately 57. The oil rotor 8 consists of an oil rotor pinion 8a, an oil rotor shaft 8b, and an oil rotor plate 8c, and the oil rotor 5 = plate 8C rotates in parallel with the cavity 13 and the cap 14. The cavity 13 is filled with silicone oil 15, and when the oil rotor 8 rotates, a load proportional to the angular velocity is generated due to viscous friction. When the oil rotor 8 rotates at 2° lrpm, this load is approximately 4.
The gap between the oil rotor plate 8C, the cavity 13, and the cap 14, and the viscosity of the silicone oil 15 are set so that 0 mg + nm. Since the cap 14 and the yoke 16 are made of high magnetic permeability material, and the oil rotor stem 8b is made of carbon steel, the magnetic flux generated by the magnet 17 forms a magnetic circuit passing through the yoke 16, the oil rotor stem 8b, and the cap 14, and the oil The magnetic fluid 18 is attracted to the gap between the rotor stem 8b and the cap 14, and prevents the silicone oil 15 in the cavity 13 from leaking from the gap. Furthermore, by making the cavity 13 made of engineering plastic, it can be tightened with the cap 14 to prevent leakage of the silicone oil 15 from the gap between the outer periphery of the cap 14 and the cavity 13, and is made of silicone oil with a relatively small coefficient of thermal expansion. This prevents leakage due to loss of tightness due to the difference in thermal expansion coefficient with the cap 14 at high temperatures. Further, the center hole of the cap 14 is a burring, and serves as a reservoir for the magnetic fluid 18.

The stepwise rotation of the rotor 4 is transmitted to the main drive wheel 6a via the fifth wheel & pinion 5. The driven wheel 6b is a hairspring 6
Since the motor rotates in balance with the torque stored in C and the load 1/rook on the oil rotor 8, it starts slowly at first. Due to the difference in the rotational speed between the main drive wheel 6a and the driven wheel 6b, the torque stored in the hairspring 6C increases, and the rotational speed of the driven wheel 6b increases until it reaches the same rotational speed as the main drive wheel 6a, 2.8 rpm, and then the speed is constant. It becomes rotation. At this time, the driven vehicle 6b is hoisted by approximately 1 rad relative to the main vehicle 6a, and the amount of the driven vehicle 6b is 30 mg+

Here, due to the step drive of the main drive wheel 6a, the torque possessed by the balance spring 6C changes before and after one winding, but the load torque of the oil rotor 8 changes in proportion to the angular velocity, so the torque retained by the balance spring 6C changes in proportion to the angular velocity. If the torque increases and the oil rotor 8 is to be rotated faster, the angular velocity increases, and as a result, the viscous load increases, which prevents the angular velocity from increasing. On the contrary, even if the torque possessed by the hairspring 6C becomes small, the oil rotor 8 can rotate at a substantially constant speed because the angular velocity is prevented from decreasing.

When adjusting the hands, the regulating lever 19 regulates the intermediate wheel 7 and at the same time comes into contact with the reset section of the circuit block.
The output of drive pulses from the IC is stopped, and the rotation of the rotor 4 is stopped. The pulling torque of the rotor 4 and stator 3 of a general step motor is approximately 30 gmm, and the oil rotor 8
2. The hairspring 6C has a torque of 30 mg + nm when rotating at lppm, and the reduction ratio of the rotor 4 and the conversion wheel 6 is approximately 43, so the hairspring 6C has a torque of 30 mg + nm.
The winding angle before regulation is maintained by the pulling torque of the stator 3 and the regulation lever 19. If the regulation is released in this state, the driven wheel 6b can immediately rotate at a constant speed.

In this embodiment, the conversion wheel 6 and the oil rotor 8 are removed from the center J of the watch body and laid out on a plane via the intermediate wheel 7. Therefore, by increasing the length of the hairspring 6C, the spring constant is reduced, thereby reducing fluctuations in the restoring force due to one step winding on the main drive wheel 63, and rotating the oil rotor 8 at a nearly constant speed. It's coming. Furthermore, by increasing the size of the oil rotor plate 8C, the gap between the cavity 13 and gap 14 and the oil rotor plate 8C can be widened under the same load, and the load caused by the inclination of the oil rotor plate 8C, cavity 13, and cap 14, etc. It becomes possible to reduce fluctuations in the load and obtain a stable load. As described above, the movement of the second hand 10 can be made smoother.
