[First Embodiment]

1 is a perspective view according to a first embodiment of the present invention, Figure 2 is a rear perspective view of FIG.

The ratchet gears which are coupled between the first and second rotation ratchet gears 210 and 220 and the first and second rotation ratchet gears 210 and 220 and the transmission shaft 231 are coupled to transmit power in one direction ( It is a structure including a second member 200 made of 230.

As shown in FIG. 3, the rotatable teeth 211 and 221 are formed in a plurality of receiving grooves 210a and 220a along the circumferential surface of the first and second rotation ratchet gears 210 and 220. Both sides 210b and 220b of each of the receiving grooves 210a and 220a are penetrated and coupled to the hinge shafts 211a and 221a so as to be rotatable only by a predetermined angle so as to be positioned. ) Is a structure in which the elastic members 211b and 221b are supported to be touched in one direction and compressed to rotate at a predetermined angle about the hinge axes 211a and 221a in the opposite direction.

In other words, the rotatable teeth 211 and 221 are rotatable through the hinge shafts 211a and 221a, but are rotated only slightly at a predetermined angle in one direction, and then locked so that they are no longer rotated. Keep it. This is because the locking surface is formed at a predetermined angle with the surface of the receiving grooves 210a and 220a forming a semi-circular shape with the bottom surfaces of the rotatable teeth 211 and 221.

On the other hand, in the opposite direction is rotated while compressing the elastic members (211b, 221b) is not lying while being protruded to be positioned in the inner direction of the receiving groove (210a, 220a).

In addition, the elastic members 211b and 221b may be used as torsion springs.

In addition, as shown in FIG. 4, as another example of the other elastic members 211c and 221c, a coil spring may be used.

At this time, the second transmission gear 120 and the second rotational ratchet gear 220 connected through the rotation shaft 121 to be engaged with the rotating first transmission gear 110 are also rotated in the counterclockwise direction. By the way, the ratchet gear 230 positioned on the side of the second rotation ratchet gear 220 is not engaged with the ratchet gear 230, the idle rotation state, which is the ratchet gear 230 is caught with the second rotation ratchet gear 220 Since the counterclockwise rotation is not made, the ratchet gear 230 can be smoothly rotated without any interference.

Meanwhile, when the first transmission gear 110 is rotated in the counterclockwise direction, the first rotating ratchet gear 210 also rotates in the counterclockwise direction, and then, the side of the first rotating ratchet gear 210 is provided. The ratchet gear 230 is rotated in an idle state without being engaged, and in this case, the second transfer gear 120 engaged with the first transfer gear 110 rotates in a clockwise direction, and at the same time, the second rotating ratchet gear 220 also rotates in a clockwise direction, and the ratchet gear 230 is engaged with the ratchet gear 230 so that the ratchet gear 230 rotates in a counterclockwise direction. Thus, the ratchet gear 230 is a first rotation ratchet gear 210. ) Is not made, so the rotation is made smoothly.

As a result, the first and second ratchet gears 240 and 250 are provided in place of the first and second rotation ratchet gears 210 and 220 in the first embodiment. The gear provided between the ratchet gears 240 and 250 is replaced by the rotation ratchet gear 260 instead of the ratchet gear 230 in the first embodiment.

FIG. 9 is the same as the structure shown in FIG. 8 except that the elastic members of the plurality of pivoting teeth 261 coupled to the pivoting ratchet gear 260 are different.

In other words, in Fig. 8, the elastic member 261a of the rotatable tooth portion 261 is a rigid torsion spring coupled to the hinge shaft 261b coupled to the rotatable tooth portion 261. The member 261c has a structure in which it is supported as a coil spring.

This structure is the same as the coupling structure of the rotational teeth 211, 221 of the first and second rotation ratchet gears 210, 220 in the first embodiment described above.

According to the second embodiment of the present invention having such a structure, as in the first embodiment, any one of the first and second transmission gears 110 and 120 is a driving means (motor that can be driven forward and reverse). When the rotation is made through the rotation axis in connection with (not shown), the rotary ratchet gear 260 is finally rotated in one direction.

Specifically, referring to the first transmission gear 110, when the first transmission gear 110 is rotated in the clockwise direction, the first ratchet gear connected through the rotational shaft 111 of the first transmission gear 110. 240 also rotates clockwise at the same time.

Accordingly, the rotation ratchet gear 260 is engaged with the rotation ratchet gear 260 so that the rotation ratchet gear 260 rotates in a counterclockwise direction, and the second ratchet gear 250 is provided on one side of the rotation ratchet gear 260. It is not done but becomes idle.

At this time, the second transmission gear 120 meshed with the first transmission gear 110 is rotated counterclockwise. Accordingly, the second ratchet gear 250 is also rotated at the same time in a counterclockwise direction. ) And the jam is not made.

On the other hand, when the first transmission gear 110 is rotated in the counterclockwise direction, the first ratchet gear 240 also rotates in the counterclockwise direction, at this time is not engaged with the rotating ratchet gear 260 is in the idle state. .

Meanwhile, the second transmission gear 120 engaged with the first transmission gear 110 rotates in a clockwise direction, and accordingly, the second ratchet gear 250 also rotates in a clockwise direction, thereby engaging the rotating ratchet gear 260. Rotating ratchet gear 260 is made to rotate in a counterclockwise direction is a power transmission is made.

In other words, even when the first transmission gear 110 is rotated in both directions (clockwise and counterclockwise), the rotary ratchet gear 260 which finally transmits power always remains in one direction (counterclockwise in this embodiment). It can rotate and transmit power.

In addition, even when the second transmission gear 120 is rotated first in both directions, the rotation ratchet gear 260 is similarly rotated in only one direction.

Third Embodiment

FIG. 10 shows a third embodiment of the present invention. Some components are the same as the first embodiment, and the other components are provided with two transmission gears in the first embodiment. On the other hand, the structure consisting of (110) and (120) is different from the structure consisting of four gears in the third embodiment.

Specifically, the first and second transmission gears 310 and 320 which are rotatably driven in both directions and the first and second meshing gears which engage with one side of each of the first and second transmission gears 310 and 320. First and second rotation ratchet gears 410 and 420 coupled to the first member 300 and the first and second driven gears 330 and 340, respectively, which are composed of driven gears 330 and 340. And a second member 400 formed between the first and second rotational ratchet gears 410 and 420 and including the ratchet gears 430 for transmitting power.

Rotating shafts 311 and 321 are respectively coupled to the first and second transmission gears 310 and 320 so as to be connected to a driving means (for example, forward and reverse driving motors) to rotate and drive.

In addition, the first and second rotational ratchet gears 410 and 420 coupled to the first and second driven gears 330 and 340 may be coupled to interlock through the concentric shafts 331 and 341. .

In addition, the first and second rotational ratchet gears 410 and 420 have a plurality of rotational teeth 411 and 421 formed along the circumferential direction, and the rotational teeth in the first and second embodiments. It is the same structure as the mold part.

In addition, the ratchet gear 430 is coupled to the transmission shaft 431 that is connected to the generator for transmitting power, for example.

FIG. 13 is a structure substantially the same as that shown in FIG. 12, except that the elastic members supported on the rotatable teeth 411 and 421 formed on the first and second rotation ratchet gears 410 and 420 are different. .

In other words, the elastic members 411b and 421b coupled to the hinge shafts 411a and 421a of the rotatable teeth 411 and 421 in the structure shown in FIG. 12 are torsion springs, and FIG. The elastic members 411c and 421c held by the rotatable teeth 411 and 421 in the illustrated structure are coil springs.

According to the third embodiment of the present invention having such a structure, it is possible to drive by connecting any one of the first and second transmission gears 310 and 320 and the driving means, which will be described based on the first transmission gear 310. do.

When the power is transmitted through the rotation shaft 3110 of the first transmission gear 310 and rotates clockwise, the second transmission gear 320 engaged with the first transmission gear 310 rotates counterclockwise, and At the same time, the first driven gear 330 provided on the side of the first transmission gear 310 also rotates counterclockwise, and the second driven gear 340 provided on the side of the second transmission gear 320 is clockwise. Rotate

The connected second rotating ratchet gear 420 also rotates clockwise at the same time.

Accordingly, as shown in FIG. 12, since the first rotational ratchet gear 410 rotates in a counterclockwise direction, the first rotation ratchet gear 410 does not engage with the ratchet gear 430 and becomes idle, and the second rotation ratchet gear 420 is rotated. ) Rotates clockwise so that the ratchet gear 430 is engaged with the ratchet gear 430 so that the ratchet gear 430 rotates counterclockwise to transmit power.

On the other hand, when the first transmission gear 310 is rotated in the counterclockwise direction, the second transmission gear 320 is rotated in the clockwise direction, the first driven gear 330 is clockwise, the second driven gear 340 Rotates counterclockwise.

According to the clockwise rotation of the first driven gear 330, the first rotational ratchet gear 410 also rotates in the clockwise direction at the same time so that the ratchet gear 430 is engaged, so that the ratchet gear 430 rotates in a counterclockwise direction. As the second driven gear 340 located on the opposite side rotates in the counterclockwise direction, the second rotating ratchet gear 420 also rotates in the counterclockwise direction. At this time, the idle state is not engaged with the ratchet gear 430. Therefore, it does not interfere with the rotation of the ratchet gear 420.

In conclusion, even if the first transmission gear 310 is rotated in both directions (clockwise and counterclockwise), the ratchet gear 430 which finally delivers power is always in one direction (counterclockwise in this embodiment). Rotation will be able to transmit power.

The same applies to the case where the second transmission gear 320 is rotated first in both directions using the drive source.

Fourth Embodiment

15 is a fourth embodiment of the present invention. Instead of the first and second rotational ratchet gears 410 and 420 constituting the second member in the third embodiment, the ratchet gear 430 is located at the center. ) Instead of rotating ratchet gears, the remaining first component is the same.

As the first ratchet gear 510 rotates counterclockwise, the ratchet gear 530 rotates in the idle state without being engaged with the rotation ratchet gear 530. On the contrary, the second ratchet gear 520 rotates clockwise to rotate the ratchet gear. 530 is engaged with the rotation ratchet gear 530 to rotate in a counterclockwise direction. Accordingly, the rotating ratchet gear 530 may transmit power through the transmission shaft 532, and for example, may be connected to a generator to perform power transmission.

On the other hand, when the first transmission gear 310 is rotated counterclockwise, the second transmission gear 320 is rotated in the clockwise direction, the first driven gear 330 is clockwise, the second driven gear 340 is Rotate counterclockwise.

The gear 530 rotates in a counterclockwise direction, whereas the second ratchet gear 520 located on the opposite side rotates in a counterclockwise direction, so that the gear 530 rotates in an idle state without being engaged with the rotation ratchet gear 530. do.

In addition, in the case of transmitting power by driving the second transmission gear 320 in both directions, the rotating ratchet gear 530 may rotate in one direction to transmit power.

As a result, even when the first and second transmission gears 310 and 320 are driven in both directions, the rotating ratchet gear 530 always rotates in one direction (counterclockwise in this embodiment) to smoothly transmit power. .

(Inner gear portion 812, 822 is coupled to the inside of the (821) and transmits power in one direction, the inner gear portion 812, 822 of the outer gear portion 811, 821 It is connected to each other and exposed to the outside of the outer gear parts 811 and 821 while being connected through the connection parts 812a and 822a inserted therein and the connection parts 812a and 822a and the shafts 812b and 822b. It is a structure composed of gear parts 812c and 822c provided.

In addition, a plurality of locking jaws 811a and 821a protruding obliquely in one direction are formed on the inner circumferential surfaces of the outer gear parts 811 and 821, and the connecting part 812a constituting the inner gear parts 812 and 822. Insertion grooves 812d and 822d are formed in the outer circumferential surface of the 822a, and are supported by the hinge shafts 812f and 812f while being supported by the elastic members 812e and 822e in the insertion grooves 812d and 822d.

In addition, the inner surfaces of the covers 812h and 822h are provided with a plurality of balls 812i and 822i along the circumferential direction so that the sliding movement is smoothly performed.

According to the seventh embodiment of the present invention having such a structure, any one of the first and second unidirectional rotary gears 810 and 820 is connected to a driving means (for example, a forward and reverse driving motor) (not shown). It can be driven in both directions to transmit power, which will be described based on the first one-way rotary gear 810 as follows.

When the shaft 812b of the first one-way rotary gear 810 connected to the driving means is rotated in the clockwise direction, the gear part 812c rotates in the clockwise direction at the same time, and the gear part of the second one-way rotary gear 820 engaged thereto. 822c rotates counterclockwise.

Then, the connecting portion 812a connected through the shaft 812b also rotates in a clockwise direction. At this time, the engaging portion 812g and the locking jaw 811a formed on the inner circumferential surface of the outer gear portion 811 are not engaged and are not in an idle state. It is rotated to prevent power transmission to the outer gear part 811.

As the gear part 822c rotates counterclockwise in the second one-way rotary gear 820, the connecting part 822a connected through the shaft 822b also rotates counterclockwise at the same time, and then the engaging piece 822g and The outer gear part 821 also rotates counterclockwise at the same time by being caught by the locking step 821a formed on the inner circumferential surface of the outer gear part 821, and the power transmission gear 910 located at the center rotates in the clockwise direction.

Accordingly, the power transmission is made through the transmission shaft 911 of the power transmission gear 910, for example, can be used in connection with the generator.

The piece 822g is not engaged with the locking jaw 821a formed on the inner circumferential surface of the outer gear part 821, and the elastic member 822e is compressed and the locking piece 822g is rotated in an idle state while being laid down. At 821, power transmission is not performed.

At this time, since the power transmission gear 910 is already rotated in the clockwise direction, the outer gear portion 821 of the second one-way rotary gear 820 engaged therewith is rotated in the counterclockwise direction, but is engaged with the locking piece 822g. Without this, the connecting portion 822a of the inner gear portion 822 rotates clockwise separately.

Similarly, in the case where power is transmitted in both directions by driving the second one-way rotary gear 820, the power transmission gear 910 may always transmit power in only one direction.

As such, when one of the first and second unidirectional rotary gears 810 and 820 is driven in both directions (clockwise and counterclockwise), the power transmission gear 910 is always in one direction (clock in this embodiment). Direction) and only power transmission can be achieved.
