  It is designed to simplify and simplify the components and make it easy for anyone to assemble and disassemble, and can be configured without any work such as keyway processing, press-fitting, and fixing. It is.

The present invention eliminates the mechanism by the conventional bearing structure and gear structure, and uses the solar axis, planetary planet, and planetary orbit ring that imitates the structure of the universe of the sun, the earth, and the moon. The first planetary, the second planetary , the double star, the outer cylinder, and the inner cylinder .

  According to the present invention, the manufacturing cost can be reduced, the assembly can be simplified and simplified, and the work can be simplified. When this mechanism becomes widespread, each industry can be developed.

FIG. 1 is an assembly sectional view as a reference. FIG. 2 is a sectional view in which a connecting rod is incorporated in FIG. FIG. 3 is a cross-sectional view when the inner cylinder is doubled. FIG. 4 is a cross-sectional view in which both planetaries are configured in a double structure. FIG. 5 is a cross-sectional view incorporating a connecting rod using the first planet as a double star . FIG. 6 is a cross-sectional view in which the outer cylinder inner cylinder is in contact, there is a space between the inner cylinder and the sun axis, and the sun axis and the planet are not in contact.

The space between the outer cylinder 1 and the sun shaft 5 is a rotary cage or a side plate having the same, and the side plate has the same size as the inner size of the outer cylinder 1 and has a shaft diameter that is slightly larger than the shaft diameter of the sun shaft 5. The one having a rotating cage is also used. In this space, the first planet 2, the inner cylinder 3, the members of the second planet 4, and the members of the double planets 2A, 4A are used. turned into it, Ru possible der possible to construct a second one-way clutch to the outside of the outer tube 1.

When each member is disposed horizontally, the inner cylinder 3 and the outer cylinder 1 arranged so as to wrap the sun axis 5 and the inner cylinder 3 around the sun axis 5 and the sun axis 5 and the inner cylinder 3 are arranged. The second planetary element 4 is arranged, and the first planetary element 2 is arranged between the outer cylinder 1 and the inner cylinder 3. When make rotating the sun shaft 5, the inner cylinder 3 by the friction between the inner surface and the sun shaft 5 of the inner cylinder 3 is rotated in the same direction as the rotational direction of the sun shaft 5. When the inner cylinder 3 rotates, the first planetary element 2 disposed between the inner cylinder 3 and the outer cylinder 1 tries to get into the gap between the inner cylinder 3 and the outer cylinder 1. The inner tube 3 is pushed relatively first Yuseiko 2 and opposition direction by biting into the first Yuseiko 2 the inner cylinder 3 and the gap between the outer tube 1, first at the inner cylinder 3 It acts so as to press the second planetary element 4 against the sun axis 5. Thus, the first planetary 2 is fixed between the outer cylinder 1 and the inner cylinder 3, and the second planetary 4 is fixed between the sun axis 5 and the inner cylinder 3, Rotation is prevented. When the sun axis 5 or each member is arranged vertically, the first planet 2, the inner cylinder 3, and the second planet 4 are in a floating state in the space between the outer cylinder 1 and the sun axis 5. Friction and biting phenomenon may not occur.

As shown in FIG. 1, when the inner side of the outer cylinder 1 and the outer side of the inner cylinder 3 are not in contact with each other and the inner side of the inner cylinder 3 and the sun shaft 5 are in contact with each other, located in the space of the tube 1 and the inner tube 3 in contact, the second Yuseiko 4, in the space of the inner cylinder 3 and the sun shaft 5, the contact with the inner cylinder 3, in contact with the sun shaft 5 However, when the action is activated on the sun shaft 5, sliding friction is generated between the inner cylinder 3 and the inner cylinder 3 is operated, and the sliding to the first planetary 2 is performed. When the outer cylinder 1 is in a stationary state, it functions as a one-way clutch.

As shown in FIG. 2, when the first planetary planet 2 and the second planetary planet 4 are held by the connecting rod 6 so as to straddle the inner cylinder 3 and are supported rotatably, the horizontal axis of the sun shaft 5 is obtained.・ It functions as a one-way clutch regardless of vertical, but it rotates in only one direction.

As shown in FIG. 3, even when the inner cylinder 3 is an inner cylinder of the first or second double structure, the number of planets is not increased .

As shown in FIG. 2, the first planet 2 and the second planet 4 are formed as a connecting rod 6 in which the moon of the upper chord is shaped , and this is not touched to the inside of the outer cylinder 1 and the axis of the sun shaft 5. full moon type not touch the diameter, i.e. that holds exert action instead copy in the disk-shaped plate. The side plate of this disk eliminates the imbalance of the members when functioning as a one-way clutch on the disk, while having the role of eliminating the intrusion of solids and foreign objects that try to enter the inner cylinder 3 , More Ru in which to have a balance function due to the weight of the order to keep the balance.

As shown in FIG. 4, each planetary element 2 , 4 is made into a double structure, and the outer envelope is processed to be thinner than the inner envelope, whereby the friction of the first planetary planet 2 and the second planetary planet 4 by the rotation of the sun axis 5. Although the biting by the head becomes larger and it functions as a one-way clutch even without a connecting rod, it functions regardless of whether the sun shaft 5 or each component is horizontal or vertical, but it is a phenomenon in which the idling time is short. Will occur.

  When the second double planet 4A is brought close to the size of the space between the sun axis 5 and the inner tube 3, and the first double planet 2A is brought close to the size of the space between the inner tube 3 and the outer tube 1, A right turn of the shaft 5 immediately becomes a right turn of the outer cylinder 1, and similarly, a phenomenon occurs in which the idling time in which the left turn turns to the left turn is short.

As shown in FIG. 6 , the inner side of the outer cylinder 1 and the outer side of the inner cylinder 3 are in contact with each other, and the inner side of the inner cylinder 3 and the sun shaft 5 are not in contact with each other. The second planet 4 is located at the lower limit of the space that is inside the inner cylinder 3 and not in contact with the sun axis 5, and is in contact with the outside of the inner cylinder 3 and the outside of the inner cylinder 3. Since 5 is in a non-contact position between the inner cylinder 3 and the second planetary planet 4, it becomes a position where the right turn and the left turn can freely idle. In this case, when the outer cylinder 1 is rotated in the direction in which the first planetary gear 2 is engaged, it functions as a one-way clutch. If the rotation of the sun shaft 5 is faster, the second is induced Yuseiko 4 depending on changes in pressure in the space is held, caught in the space of the inner cylinder 3 and the sun shaft 5 Therefore, it is necessary to hold the second planetary member 4 mechanically .

When the inner side of the outer cylinder 1 and the outer side of the inner cylinder 3 are in contact with each other, the first planet 2 is inserted into the space, and there is a space between the inner side of the inner cylinder 3 and the sun axis 5, the numerical value of the space is When the outer cylinder 1 is actuated in the direction where the first planetary element 2 is engaged, it functions as a one-way clutch and becomes a slipping position due to the reaction, but when the numerical value of the space increases, Even if the members configured in the space of the tube 1 mesh with each other, the glide state is achieved.

The first planetary element 2 is installed in a space inside the outer cylinder 1 and outside the inner cylinder 3, but the numerical value of the size is centered on the sun axis 5 rather than the size of the outer cylinder 1. those obtained by subtracting the size of the inner cylinder 3, for a space to be a polarized heart, the size of the inner cylinder 3, but Ru different also depending on for work, and become too small numbers, can not be held in the space The phenomenon of slipping through occurs. Larger numbers result in less space, faster operation, and shorter idle time.

The second planetary planet 4 is installed inside the inner cylinder 3 and in the space of the sun axis 5, but the numerical value of its size cannot react to the rotating action of the sun axis 5 if it is too small. When to a number of space decreases, a phenomenon that react faster idling time, depending for work, in which the numerical value is changed.

As shown in FIG. 2 , the second planet 4 is arranged in a space between the axis diameter of the sun shaft 5 and the inner side of the inner cylinder 3, and the size thereof is the axis diameter of the sun axis 5. It is necessary to be closer to the numerical value obtained by subtracting from the inner size of the inner cylinder 3.

The relationship between the outer cylinder 1 and the inner cylinder 3 is that when the outer cylinder 1 and the inner cylinder 3 are engaged with the sun shaft 5 and the second planetary planet 4 and function as a one-way clutch, the outer cylinder 1 and the inner cylinder 3 atmosphere of numerical incorporated narrowing first Yuseiko 2 chewy space is required.

The inner cylinder 3 in the present invention is intended to be a place subject to most Dai応 force, external pressure, Ru products der strength can be maintained to withstand the internal pressure. Further, the inner cylinder 3 skin, weighed duplex endothelial, also of that in response to changes due to stress. Although it is necessary to process the cutting line on the outer skin side to cope with the stress, it is not necessary to duplicate all of them, and it corresponds to each device.

Setting numerical axis diameter of each Yuseiko 2,4, the inner cylinder 3, setting value of the inside diameter outside diameter of the outer cylinder 1 is Ru is set at design time.

Any material can be used for the planetary elements 2 and 4 as long as they are molded. The outer cylinder 1 and the inner cylinder 3 are possible if they have strength values that do not cause deformation wear when sliding friction occurs.

The place where biting sliding friction occurs is a point or line, so it also occurs in water or oil, but if there is a place where the area of the pressure contact surface / contact surface increases, the one-way clutch It does not function as a glide state may occur.

The planetary bodies 2 and 4 have a cylindrical shape as a standard, and may be a round bar shape, a modified shape thereof, a spherical shape, a half note type, or the like.

The outer cylinder 1, inner cylinder 3 is a cylindrical shape, the sun shaft 5 of the rod-like, or Ru hollow der, if variants are biting, for sliding inclusive conditions are different, it is not suitable.

Although the connecting rod 6 according to the present invention was mentioned in paragraph 0015, the planetary rods 2 and 4 are not fixed to each other and are constituted by numerical values that can be moved, and the positions thereof are the inside of the outer cylinder 1 and the sun shaft 5. The position at which the first planet 2, the second planet 4, the twin stars, etc. operate is transferred to a disk-shaped rotating body that does not touch the shaft diameter of the first and second planets . Further, a disc-shaped coupling plate is arranged in the space by dividing the inner cylinder 3, it is also possible to make exert the effect by holding the first Yuseiko 2 and the second Yuseiko 4.

In each contact surface of the outer cylinder 1 , the inner cylinder 3, the first planetary planet 2, and the second planetary planet 4, it is also possible to apply a line scar or a lining and drilling to measure an increase in sliding friction. It is.

In the present invention, the sun shaft 5, various processing operations of the outer cylinder 1 is simplified, so far necessary and there was keyway machining, press-fitting process or the like, along with those to be useless unless specific When the sun shaft 5 is in the idling position, the outer cylinder 1 can be moved.

Even when the input side is set to the outer cylinder 1 instead of the sun shaft 5, it functions as a one-way clutch in which the sun shaft 5 is the output side.

When the one-way clutch of the present invention is rotated at a high speed, the position that functions as the one-way clutch becomes unbalanced depending on the components. Therefore, it is necessary to incorporate a pendulum type or disc type balance weight that automatically adjusts the eccentricity. Therefore, it is necessary to adjust the entire structure, and there are many advance inventions (see Japanese Patent No. 3984630) .

By structurally moving, displacing, and controlling the first planetary 2 and the second planetary 4 that are configured according to the present invention, it is possible to diversify such as correspondence to various devices.

As shown in FIG. 5, when two first planets 2 arranged in the space between the outer cylinder 1 and the inner cylinder 3 are arranged as double stars and are connected by a connecting rod 7, the sun shaft 5 is on the input side. 1 is the same as the example shown in FIG. 1, but when the outer cylinder 1 is on the input side, the action of the outer cylinder 1 is transmitted in a shorter time than in the case of a single planetary planet . The shaft diameter of one planetary planet 2 is not limited to the same size, and may be a different diameter shaft depending on the configuration method.

When the sun shaft 5 acts as an input shaft, the sun shaft 5, the second planet 4 and the inner cylinder 3 are in contact positions, and when they are in the idling position as a reaction, they become friction generating positions. It is necessary to reduce the generation of heat. When the outer cylinder 1 is on the input side and the sun axis 5 is in the idling position in a stationary state, the outer cylinder 1, the first planet 2, the inner cylinder 3, the second planet 4, the sun axis 5 Although but Ru Tei in contact with each other, the outer cylinder 1 acting, first Yuseiko 2 only, the inner cylinder 3, the second Yuseiko 4, the transmission of the action of the sun shaft 5 is rather free, optionally May be possible without using a method for reducing friction such as fats and oils.

In Fig. 1, when located at a position outside it does not contact the outer tube 1 inside the inner tube 3, and holds the first Yuseiko 2 to the upper limit position of the space between the outer tube 1 and the inner cylinder 3, If the position does not contact there is a space between the outer cylinder 1, when the outer cylinder 1 and the input side, its action is not transmitted first in Yuseiko 2, the position of the idling is maintained a shall, but when the sun shaft 5 is activated to effect functions as a one-way clutch collapsed its equilibrium.

Both the outer cylinder 1 and the sun shaft 5 are rotated as rotation axes. It is also possible to move together the generators of the one-way clutch incorporated in the space between the outer cylinder 1 and the sun shaft 5 on the same axis by utilizing the idling position with the difference in the rotational value .

The present invention functions as a one- way clutch by the configuration of the outer cylinder 1, the first planet 2, the inner cylinder 3, the second planet 4, and the sun shaft 5, but the inner cylinder 3, the second planet. Depending on the configuration method of the child 4 and the sun shaft 5, it is possible to provide a one-way clutch with fewer components.

In the configuration method, the second planet 4 and the sun shaft 5 are arranged in the space of the inner cylinder 3, but the second planet 4 has a single action and the second planet. When 4 is used as a plurality of planets having no connection rod, a one-way clutch that changes depending on the shaft diameter of the planets is obtained.

  The sun shaft 5 in the space of the inner cylinder 3 is constituted by a side plate having a shaft aperture having a space slightly larger than the size of the inner cylinder 3 and the shaft diameter of the sun shaft 5 without being held by the rotary cage. 3 itself is used as a friction biting member.

The function as a one-way clutch that occurs in the space between the inner cylinder 3 and the sun shaft 5 is a device that does not use a rotating cage as a reference, but when the sun shaft 5 idles in the space of the inner cylinder 3, If it is possible to move to a position that contacts the inside, it is also possible to use a rotating cage .

The shape of the inner cylinder 3 is not limited to the cylindrical type, but functions as a one-way clutch in any shape, at the space of the cylindrical outer tube 1, when the sun shaft 5 is the central axis, the spring claw , reinforcing such latches and bolts, or the holding member is required bur not limited to a cylindrical space by the space of the inner cylinder 3, in order to correspond processed any shape, dare use springs, also the auxiliary material such as bolts In addition, there is one that further promotes the function as a one-way clutch (see Japanese Patent No. 2025982) .

In the present invention, even when the sun shaft 5 is a position of the eccentric not located at the center axis of the outer cylinder 1, by which development of the structure of FIG. 1, but is intended to function as a one-way clutch, the outer cylinder 1 Since the size of the shaft diameter of the inner cylinder 3 is greatly related, even if the shape of the outer cylinder 1 is an egg shape, a square shape, or other irregular shapes, one-way can be achieved by developing the structure shown in FIGS. At the same time it made to function as a clutch can, first Yuseiko 2 disposed in the space, the second Yuseiko 4 also, the shaft diameter is affected by the size of the space, also occur whether the arrangement of their is intended, therefore, the one-way clutch, the linkage of certain numbers, form and function, regardless of size.

The present invention is the one-way clutch and the configuration of the bearing type or machine combination type so far is quite different, diversion to methods so far that has been implemented is made possible unless the specific ones is there.

  It can be effectively used in the fields of vehicles, industrial equipment under severe conditions, shaft joints, fishing gear, shutters, conveyors, tools and the like.
