JP 2002-66864 A

  A mechanism for converting a reciprocating motion into a unidirectional rotational motion is known in Patent Document 1 and the like, but can transmit only intermittent rotation and is not suitable as a mechanism for continuous rotation. In order to increase the torque of the rotational force obtained by the reciprocating motion, it is necessary to combine a plurality of transmission gears, a belt mechanism, and the like. Furthermore, in order to make the rotational motion rotation axis orthogonal, orthogonal bevel gears or the like must be used, which increases the number of transmission elements and makes them complicated.

When the rotating disk rotates, the swing arm reciprocally swings about the rotation center of the reciprocating drive gear. The one-way rotation conversion mechanism includes a first conversion unit and a second conversion unit, and each of the first conversion unit and the second conversion unit reciprocally rotates. A gear, a one-way clutch, and a driven shaft. The rotating gear is reciprocally rotated by the reciprocating drive gear, the reciprocating rotation is converted into a one-way rotation by a one-way clutch and transmitted to the rotating shaft, and the interlocking output mechanism is connected to the first conversion unit.

  EMBODIMENT OF THE INVENTION The form for implementing the power transmission device which concerns on this invention is demonstrated below with reference to drawings based on an Example.

  FIG. 1 is a diagram schematically illustrating the principle, configuration, operation, and the like of a power transmission device according to a first embodiment of the present invention. FIGS. 2 to 4 illustrate the power transmission device according to the first embodiment of the power transmission apparatus according to the first embodiment. It is a figure explaining a structure. As shown in FIGS. 1 to 3, the power transmission device 1 according to the first embodiment includes a reciprocating rotation generating mechanism 2, a one-way rotation converting mechanism 3, and an interlocking output mechanism 4.

  The reciprocating rotation generating mechanism 2 is a mechanism that applies a reciprocating rotational force to a part of the circumferential surface of the reciprocating drive gear 5 to rotate the reciprocating drive gear 5 reciprocally about its axis. The unidirectional rotation conversion mechanism 3 is a mechanism that converts the reciprocating rotation of the reciprocating drive gear 5 into a unidirectional rotation. The interlocking output mechanism 4 is a mechanism that takes out the rotation in one direction converted by the one-way rotation conversion mechanism 3 as an output. Hereinafter, the configuration and operation of the first embodiment will be described in detail.

(Reciprocating rotation generation mechanism)
As shown in FIGS. 1 to 3, the reciprocating rotation generating mechanism 2 includes a reciprocating drive gear 5 (gear that drives reciprocating rotation), a swing mechanism 6 that generates reciprocating rotation, and an input shaft 16. The reciprocating drive gear 5 is concentrically fixed to a rotating shaft 7, and the rotating shaft 7 is rotatably attached to a first fixed frame 8 by a bearing (not shown). In the reciprocating drive gear 5, a bifurcated yoke 9 is provided so as to protrude from the gear surface on one side thereof in the radial direction from the axis of the gear.

  Note that the reciprocating drive gear 5 may be concentrically attached to a fixed shaft fixed to the first fixed frame 8.

  The swing mechanism 6 includes a swing arm 10 and a rotating disk 11. A flat portion 12 is formed at the base end portion of the swing arm 10, and this flat portion 12 is fitted between the flat inner surface 13 of the bifurcated yoke 9 of the reciprocating drive gear 5, and the yoke shaft 14 It is clamped so that it can rotate between the flat inner surfaces 13 of the forked yoke 9. A sphere 15 is formed at the tip of the swing arm 10.

  The rotating disk 11 is concentrically attached to the input rotating shaft 16. The input rotary shaft 16 is rotatably attached to the second fixed frame 17 by a bearing (not shown), and is rotationally driven by a prime mover such as an electric motor, a hydraulic motor, or an engine. In short, the input rotation shaft 16 constitutes the input shaft of the power transmission device 1. The rotating disk 11 is formed with a socket 18 having a spherical receiving surface at a position near its periphery. The first fixed frame 8 and the second fixed frame 17 are provided upright on the base 19.

  As shown in FIG. 1, the spherical body portion 15 formed at the distal end portion of the swing arm 10 is rotatably fitted in the receiving surface of the socket 18 of the rotating disk 11. In short, the ball portion 15 formed at the tip of the swing arm 10 is fitted into the socket 18 to constitute a ball joint.

  When the rotating disk 11 is rotated by the input rotating shaft 16, as shown in FIG. 1, the sphere 15 at the tip of the swing arm 10 rotates (revolves) with the rotating disk 11 while rotating at the ball joint. Thus, when the spherical body portion 15 rotates together with the rotating disk 11, the flat portion 12 of the swing arm 10 can rotate around the yoke shaft 14 between the flat inner surfaces 13 of the bifurcated yoke 9.

  In addition, as shown in FIG. 1, the whole of the swing arm 10, the bifurcated yoke 9, and the reciprocating drive gear 5 is reciprocally driven as if constituting one insulator when viewed from the front. The gear 5 reciprocates around the axis of the rotary shaft 7. If this pays attention to the reciprocating drive gear 5, it means that the reciprocating rotation is carried out around the axis of the rotating shaft 7 together with the rotating shaft 7.

  The reciprocating rotation generating mechanism 2 only needs to reciprocately rotate the reciprocating drive gear 5 together with the rotating shaft 7 and has a configuration including a swing arm 10 and a rotating disk 11 as in the first embodiment. It is not always necessary. In a second embodiment to be described later, a reciprocating rotation generating mechanism in which the reciprocating drive gear 5 reciprocates together with the rotating shaft 7 using a swing arm and a rotating disk having different configurations will be described. Further, for example, the tip end side of the swing arm 10 may be reciprocated by a linear reciprocating mechanism such as a cylinder piston.

(One-way rotation conversion mechanism)
The one-way rotation converting mechanism 3 is a mechanism for converting the reciprocating rotation of the reciprocating drive gear 5 generated by the reciprocating rotation generating mechanism 2 into one-way rotation. As shown in FIGS. 21 and a second conversion unit 22. The first conversion unit 21 and the second conversion unit 22 have the same configuration.

  As shown in FIGS. 1 to 4, the first converter 21 includes a first reciprocating rotary gear 23, a first one-way clutch shaft 24, and a first rotated shaft 25. A first one-way rotating gear 26 of the interlocking output mechanism 4 to be described later is coaxially fixed to the first rotated shaft 25.

  As shown in FIG. 4, the first reciprocating rotation gear 23 is formed integrally with a gear portion 27 and a boss portion 28 formed in an annular shape. The inner peripheral surface of the gear portion 27 is supported by being fitted to the outer peripheral surface of the first one-way clutch shaft 24 and can rotate the first one-way clutch shaft 24 only in one direction as will be described later. And The first reciprocating rotation gear 23 is in mesh with the reciprocating drive gear 5. The boss portion 28 is rotatably attached to the first fixed frame 8 by a bearing 29.

  As shown in FIG. 4, the first one-way clutch shaft 24 has a cylindrical portion 30 formed at the tip thereof, and is rotatably attached to the first fixed frame 8 by a bearing 31 in the cylindrical portion 30. . And the base end of the 1st to-be-rotated shaft 25 is fitted concentrically to this cylindrical part 30, and it is fixed by screwing. A first one-way rotating gear 26 of the interlocking output mechanism 4 is concentrically fixed to the first rotated shaft 25.

  A plurality of depressions 32 are formed on the inner peripheral surface of the first reciprocating rotation gear 23 at regular intervals in the circumferential direction. The plurality of dents 32 are gradually formed deeper in the outer circumferential direction toward one direction in the circumferential direction of the first reciprocating rotary gear 23 (counterclockwise in the example of FIG. 1), and are wedge-shaped in cross section (tapered in cross section). It is formed as an indented.

  In the space formed by the recess 32 and the outer peripheral surface of the first one-way clutch shaft 24, as shown in FIG. 1, a spherical clutch ball 33 or a cylindrical clutch roller (hereinafter referred to as the present embodiment). 1 is described with a clutch ball 33).

  A wedge-shaped recess 32 formed on the inner peripheral surface of the first reciprocating rotary gear 23, a clutch ball 33, and a first one-way clutch shaft 24 form a first one-way clutch 34. By providing such a first one-way clutch 34, as shown in FIG. 1, when the first reciprocating rotation gear 23 rotates counterclockwise, the clutch ball 33 moves to a shallow portion of the wedge-shaped recess 32. The first one-way clutch shaft 24 is pressed and rotated counterclockwise, and the first reciprocating rotation gear 23 transmits the counterclockwise rotation to the first one-way clutch shaft 24.

  On the contrary, when the first reciprocating rotation gear 23 rotates in the clockwise direction, the clutch ball 33 moves to a deep portion of the wedge-shaped deep recess 32 and enters a play state, so that the first one-way clutch shaft 24 is pressed. The first reciprocating gear 23 rotates freely with respect to the first one-way clutch shaft 24, and the first reciprocating gear 23 rotates clockwise to the first one-way clutch shaft 24. Do not communicate.

  Thus, only the counterclockwise rotation of the first reciprocating rotation gear 23 is transmitted to the first one-way clutch shaft 24. The counterclockwise rotation is further transmitted from the first one-way clutch shaft 24 to the first one-way rotation gear 26 via the first rotated shaft 25. Eventually, when the first reciprocating rotation gear 23 reciprocates, the first one-way rotation gear 26 rotates intermittently counterclockwise.

  As shown in FIGS. 1 and 2, the second conversion unit 22 includes a second reciprocating rotation gear 35 that meshes with the first reciprocating rotation gear 23, a second one-way clutch shaft 36, The rotation shaft 37 is provided. The second reciprocating rotary gear 35, the second one-way clutch shaft 36, and the second rotated shaft 37 in the second converting unit 22 are the first reciprocating rotary gear 23 and the second revolving rotary shaft 37 in the first converting unit 21, respectively. The one-way clutch shaft 24 and the first rotated shaft 25 have the same configuration. A second unidirectional rotating gear 38 is concentrically fixed to the second rotated shaft 37.

  Like the first reciprocating rotary gear 23, the second reciprocating rotary gear 35 has a plurality of wedges 32 having a wedge-shaped cross section, and the clutch ball 33 is inserted into the recess 32. A second one-way clutch 39 is configured together with the second one-way clutch shaft 36. In short, the configuration of the second conversion unit 22 is the same as the configuration of the first conversion unit 21 as described above, and a detailed description thereof is omitted here.

  The operation of the second conversion unit 22 is the same as the operation of the first conversion unit 21. That is, in the second converter 22, only when the second reciprocating rotation gear 35 rotates counterclockwise, the second one-way rotating gear 39 rotates clockwise, and the second reciprocating rotation gear 35 rotates. When rotating clockwise, the rotation is not transmitted to the second one-way rotating gear 39. Eventually, when the second reciprocating rotation gear 35 reciprocates, the second one-way rotation gear 39 rotates intermittently counterclockwise.

  What should be noted here is that the first reciprocating gear 23 and the second reciprocating gear 35 mesh with each other, and therefore the directions of reciprocating rotation are opposite to each other. 34 and the second one-way clutch 39, the first one-way rotating gear 26 and the second one-way rotating gear 38 rotate intermittently in the same direction, and will also be described in the section of action described later. However, the intermittent rotation of the first unidirectional rotating gear 26 and the intermittent rotation of the second unidirectional rotating gear 38 occur not at the same time but at different timings.

  Then, by the interlocking output mechanism 4 described below, the first one-way rotating gear 26 and the second one-way rotating gear 38 are interlocked with each other by the transmission means, and intermittent output rotation by the first converter 21 is performed. The intermittent output rotation by the second conversion unit 22 is adjusted so as to complement the rotation period.

(Linked output mechanism)
The interlocking output mechanism 4 is a part having a function of outputting the output rotation by the first conversion unit 21 and the output rotation by the second conversion unit 22 so as to compensate for the rotation period.

  As shown in FIGS. 1 and 3, the interlock output mechanism 4 includes a first one-way rotating gear 26 (first one-way rotating member) fixed concentrically to the first rotating shaft 21, And a second one-way rotating gear 38 (second one-way rotating member) fixed concentrically to the second rotated shaft 37, and the first one-way rotating gear 26 and the second one-way rotation. Transmission means and an output rotating shaft 41 for interlocking the gears 38 are provided. The first one-way rotating gear 26 and the second one-way rotating gear 38 have the same configuration, that is, the same configuration in diameter and number of teeth.

  In the first embodiment, a chain 40 mounted between the first one-way rotating gear 26 and the second one-way rotating gear 38 is provided as the transmission means. Although not shown, the first one-way rotating gear 26 and the second one-way rotating gear 38 are not directly linked by the chain 40, and the chain travels between the two gears 26 and 38 as necessary. An idle gear (not shown) may be provided on the road, and the chain may be attached via the idle gear.

  Moreover, as a transmission means, you may employ | adopt the gear transmission mechanism via the intermediate gear between the 1st one way rotation gear 26 and the 2nd one way rotation gear instead of the chain 40. FIG.

  The first unidirectional rotating member and the second unidirectional rotating member are not gears, but have the same configuration, that is, rollers having the same diameter, and the transmission means includes at least the first unidirectional rotating member and the second unidirectional rotating member. It may be a transmission mechanism such as a belt attached to the unidirectional rotating member.

  The rotational output is taken from the first one-way rotating gear 26 or the second one-way rotating gear 38. In the first embodiment, the output is taken out from the output rotation shaft 41 of the second one-way rotation gear 38. In the first embodiment, the output rotating shaft 41 uses the second driven shaft 37 in common. However, the output rotating shaft 41 may be a different shaft, or the rotation of the second one-way rotating gear 38 may be different. It is good also as a structure taken out through the gear of this.

  If the flywheel 42 is concentrically fixed to the output rotation shaft 41, a smooth rotation output can be obtained by the rotation inertia force, and the first one-way rotation gear 26 and the second one-way rotation gear 38 are provided. Even if the rotation is intermittent, smooth rotation can be obtained as a whole.

(Function)
The operation of the power transmission device 1 of the first embodiment having the above configuration will be described. As shown in FIGS. 1 and 2, when a rotation input is applied to the input rotation shaft 16, the rotating disk 11 rotates. When the rotating disk 11 rotates, the flat portion 12 at the base end portion of the swing arm 10 rotates about the yoke shaft 14 between the flat inner surfaces 13 of the bifurcated yoke 9 (rotates in a two-dimensional plane). At the same time, the spherical portion 15 at the tip of the swing arm 10 rotates in the socket 18 of the rotating disk 11 (rotates in a three-dimensional space) and follows the rotation of the rotating disk 11 so as to follow the socket of the rotating disk 11. It rotates (revolves) along 18 rotation trajectories.

  Then, the reciprocating drive gear 5 reciprocates with the bifurcated yoke 9 around the axis of the rotating shaft 7 to reciprocate the first reciprocating rotating gear 23. That is, the reciprocating drive gear 5, the bifurcated yoke 9, and the swing arm 10 as a whole act as a lever (moment arm) around the axis of the rotating shaft 7, and the first reciprocating rotating gear 23 is reciprocated. Further, the second reciprocating rotation gear 35 is reciprocally rotated.

  At this time, as shown in FIG. 1, the length from the axial center of the rotating shaft 7 to the distal end portion (spherical portion 15) of the swing arm 10 in the length on the projection surface viewed from the front is L1, the rotating shaft. 7 to the tooth of the reciprocating drive gear 5 (more precisely, the portion meshing with the first reciprocating rotary gear 23), the length of the rotary disc 11 is added to the tip of the swing arm 10. The generated rotational force F becomes F × L1 / L2 according to the principle of leverage, and is increased and transmitted to the first reciprocating rotary gear 23.

  When the reciprocating drive gear 5 rotates in the clockwise direction and the first reciprocating rotating gear 23 rotates in the counterclockwise direction, the clutch ball 33 moves relative to the shallow portion of the wedge-shaped recess 32, and the first first reciprocating gear 23 rotates. The directional clutch shaft 24 is rotated counterclockwise while being pressed.

  Even if the first reciprocating rotation gear 23 rotates in the clockwise direction, the clutch ball 33 moves to a deep portion of the wedge-shaped depression 32, so that the first one-way clutch shaft 24 is not pushed and the first The reciprocating rotation gear 23 rotates freely (swings) with respect to the first one-way clutch shaft 24, and the first reciprocating rotation gear 23 does not transmit the clockwise rotation to the first one-way clutch shaft 24. .

  Thus, only the counterclockwise rotation of the first reciprocating rotation gear 23 is transmitted to the first one-way clutch shaft 24. The counterclockwise rotation is further transmitted to the first one-way rotating gear 26 via the first rotated shaft 25. Eventually, when the first reciprocating rotation gear 23 reciprocates, the first one-way rotating gear 26 rotates intermittently counterclockwise due to the counterclockwise rotation.

  When the first reciprocating rotation gear 23 rotates in the clockwise direction, the second reciprocating rotation gear 35 rotates in the counterclockwise direction in the second conversion unit 22, as in the case of the first reciprocating rotation gear 23. The second one-way clutch 39, the second one-way clutch shaft 36, the second rotated shaft 37, and the like rotate the second one-way rotating gear 38 counterclockwise. Eventually, as with the first converter 21, in the second converter 22, when the second reciprocating rotary gear 35 reciprocates, the second one-way rotary gear 38 rotates intermittently in the counterclockwise direction. .

  Here, the operations from the reciprocating drive gear 5 to the first conversion unit 21 and the second conversion unit 22 and further to the interlocking output mechanism 4 are arranged. When the reciprocating drive gear 5 rotates clockwise, the first reciprocating rotating gear 23 rotates counterclockwise, and the first one-way rotating gear 26 is counterclockwise via the first one-way clutch 34. The second reciprocating gear 35 is rotated in the clockwise direction, but the rotation is not transmitted to the second one-way rotating gear 38.

  Further, when the reciprocating drive gear 5 rotates counterclockwise, the first reciprocating rotational gear 23 rotates clockwise, but the rotation is not transmitted to the first one-way rotating gear 26 and the second reciprocating rotational gear 26 is rotated. The gear 35 rotates counterclockwise to rotate the second one-way rotating gear 38 counterclockwise via the second one-way clutch 36.

  Accordingly, during the period in which the reciprocating drive gear 5 rotates in the clockwise direction, the first one-way rotating gear 26 rotates in the counterclockwise direction, and during the period in which the reciprocating driving gear 5 rotates in the counterclockwise direction, the second one direction The rotating gear 38 rotates counterclockwise. In short, in any direction of the reciprocating rotation of the reciprocating drive gear 5, either the first one-way rotating gear 26 or the second one-way rotating gear 38 rotates counterclockwise to produce a rotation output. Will occur.

  Since the first one-way rotating gear 26 and the second one-way rotating gear 38 are interlocked by the chain 40, the first one-way rotating gear 26 and the second one-way rotating gear 38 are connected to each other. The rotations are adjusted so as to compensate for a period in which the rotations do not rotate with each other, and are extracted from the output rotation shaft 41 as a counterclockwise rotation output. If the flywheel 42 is attached to the output rotation shaft 41, the inertial force acts to obtain a smooth rotation output.

  FIG. 5 is a diagram schematically illustrating the configuration and operation of the power transmission device according to the second embodiment of the present invention. In the second embodiment, the one-way rotation conversion mechanism 3 and the interlocking mechanism 4 are the same as in the first embodiment, but the reciprocating rotation generation mechanism is different. Hereinafter, the second embodiment will be described focusing on the reciprocating rotation generating mechanism 2 '.

  In the second embodiment, the reciprocating rotation generating mechanism 2 ′ has a reciprocating drive gear 5 and a swing mechanism 6 ′ that generates reciprocating rotation, as shown in FIG. 5, as in the first embodiment. The reciprocating drive gear 5 is the same as that of the first embodiment, is concentrically fixed to a rotating shaft 7 rotatably attached to a first fixed frame 8 by a bearing, and is rotatably supported by the first frame 8. ing. In the reciprocating drive gear 5, a bifurcated yoke 9 projects from the gear surface on one side thereof in the radial direction from the shaft center of the gear.

  As shown in FIG. 5, the rotating disk 45 is disposed in the same direction as the reciprocating drive gear 5 (front direction in FIG. 5), and is concentrically fixed to the input rotating shaft 16 '. Therefore, the second fixed frame 17 ′ that supports the input rotary shaft 16 ′ via a bearing has the same orientation as the first fixed frame 8 that rotatably supports the rotary shaft 7 of the reciprocating drive gear 5 (FIG. 5). (Center front direction).

  One end of a connecting link 46 composed of two link rods is pivotally attached to the surface near the peripheral edge of the rotating disk 45. The tip of the swing arm 10 ′ is pivotally attached to the other end of the connecting link 46. A flat portion 12 is formed at the base end portion of the swing arm 10 ′ similarly to the first embodiment, and this flat portion 12 is screwed between the flat inner surface 13 of the bifurcated yoke 9 fixed to the reciprocating drive gear 5. 47 is fixed.

  According to the reciprocating rotation generating mechanism 2 ′ of the second embodiment configured as described above, when the input rotating shaft 16 ′ rotates and the rotating disk 45 rotates, the swing arm 10 ′ is centered on the axis of the rotating shaft 7. The reciprocating drive gear 5 and the bifurcated yoke 9 oscillate in one vertical plane. By this swinging, the reciprocating drive gear 5 is reciprocally rotated around the axis of the rotating shaft 7. The reciprocating rotation of the reciprocating drive gear 5 operates the unidirectional rotation converting mechanism 3 in the same manner as in the first embodiment, and the interlocking output mechanism 4 provides a unidirectional rotational output.

  As mentioned above, although the form for implementing the power transmission device which concerns on this invention was demonstrated based on the Example, this invention is not limited to such an Example, The technique described in the claim It goes without saying that there are various embodiments within the scope of the subject matter.

  For example, in the interlock output mechanism, a first one-way rotating gear, a second one-way rotating gear, a chain, and the like are used, but rollers and a belt may be used instead of the gear and the chain. The one-way clutch may be any one of various known one-way clutches, not the one-way clutch described in the embodiment.

  Since the power transmission device according to the present invention has the above-described configuration, the field of energy technology such as a power transmission device that rotates the generator using the rotational force of the wind turbine of wind power generation, and other industrial technology fields. It is applicable to. In particular, since the rotational torque can be increased by utilizing the lever principle, it is suitable for a device requiring a large torque.
