Problems solved by technology

[0042] (1-3) The magnetic flux leakage of the braking governor using eddy current will affect the surroundings
[0043] (2-1) In the case of the vibrator type, the escapement speed governor with inherent vibration cannot adapt to the change of posture, cannot be used in portable equipment, and produces a click sound
In the case of using a spring vibrator, the cost is high due to the need for high-precision parts such as hairspring, balance wheel, escape wheel, pallet fork, etc., and a large installation space is required, and the escapement mechanism produces a striking sound
[0044] (2-2) The escapement type governor without inherent vibration has a large vibration of the beating sound emitted by the escapement mechanism, and causes wear and tear, resulting in shortened life
The contact part is filled with oil to suppress friction, but even with lubrication, the coefficient of friction increases due to changes in the amount of oil (volatilization / diffusion) or deterioration, contamination of the lubricated film surface, etc.
Therefore, there are also problems such as deviation from the set speed during repeated use, resulting in changes in the hitting interval of the bell, etc.

no. 1 approach

[0156] The first embodiment of the present invention will be described below.

[0157] figure 1 It is a plan view showing the timepiece 1 of the first embodiment. The timepiece 1 is equipped with a chime mechanism 3 on the dial side as a base, and the speed regulating device 2 of the present invention is used for the operation of the chime mechanism.

[0158] In addition, the mechanical device for driving the hands of the timepiece 1 may have any structure of a mechanical timepiece, an analog quartz timepiece, or an electronically controlled mechanical timepiece. However, in mechanical clocks and watches, the governor composed of balance wheel, hairspring, pallet fork, and escape wheel produces striking sound, and in analog quartz clocks and watches, it produces magnetoelastic sound and tooth collision sound, which affects the timbre of the self-sounding mechanism. . Therefore, it is preferable to use an electronically controlled mechanical timepiece that hardly generates n...

no. 2 approach

[0270] Below, based on Figures 9A-9C A second embodiment of the present invention will be described. The second embodiment is an embodiment in which the outer peripheral shape of the blade 210 is slightly changed in the speed control device 2 of the first embodiment, and other structures are the same as those of the first embodiment, and description thereof will be omitted.

[0271] That is, the wing 210A of the second embodiment has a shape along the inner peripheral edge of the hole 233A of the opposing plate 233 . Specifically, as Figure 9B As shown, part of the outer peripheral shape of the wing 210A, more specifically, the outer peripheral shape from the tip of the wing 210A to the vicinity of the wing shaft 211 is a shape along the inner peripheral edge of the hole 233A of the opposing plate 233 .

[0272] Also in the speed regulating device 2 configured in this way, the same operational effects as those of the first embodiment can be obtained.

[0273] In addition,...

no. 3 approach

[0275] In the third embodiment, as shown in FIGS. 10 and 11 , a counter 300 having a shape integrated with the upper and lower facing plates 233 of the speed regulating device 2 is used as the counter. That is, the counterpart 300 is formed with a groove 301 into which the wing 210 moved outward by centrifugal force enters.

[0276] In the present embodiment, the circumferential groove 301 is formed by combining two counterparts 300 in which the groove 301 is formed into a C-shaped ring.

[0277] Each counterpart 300 is guided by a guide pin 302 inserted into a long hole formed in the counterpart 300 so as to be linearly movable. In addition, each counterpart 300 receives elastic force in a direction away from each other, that is, a direction away from the rotation axis of the rotor 200 , by the spring 303 provided integrally with the counterpart 300 .

[0278] The distance between the counterparts 300 can be finely adjusted by screwing the adjustment screws 304 of the bottom...

technical field [0001] The present invention relates to a speed regulating device utilizing the viscosity of a fluid, and a power generation device and equipment using the speed regulating device. Background technique [0002] In the past, in order to maintain a constant working speed of equipment powered by energy storage units that store various energies, the method of installing a governor to gradually release the stored energy is adopted. Such mechanical energy, potential energy such as counterweight, thermal energy such as supplying heat to or absorbing heat from the corrugated airtight container, etc. [0003] Such a speed governor includes, for example, a mechanical speed governor and an electronically controlled speed governor. [0004] The electronically controlled speed governor is equipped with a generator that rotates by the accumulated energy, and by electronically controlling the rotation to adjust the rotation speed, so that the electronically controlled spee...
