  As shown in FIGS. 1 to 4, each of the six round bar-like connecting pins 46 has one end portion (left end portion in FIG. 4) in the length direction of the rotating body 32 on the outside (left side in FIG. 4). Is fitted to a bush 54 embedded in the outer through-hole 32c of the inner side, and the middle part on the other end (right end in FIG. 4) side in the length direction is the inner (right end in FIG. 4) rotating body. 32 is fitted into a bush 54 embedded in the outer through hole 32c.

  For this reason, each of the six connecting pins 46 has an axial center that is horizontal and substantially parallel to the axial center of the shaft gear 34, and is rotatably supported by the rotating body 32.

  As shown in FIGS. 2 and 3, the six outer gears 38 are formed in a cylindrical gear shape, and the surfaces on both sides perpendicular to the axis are the inner surfaces of the inner rotating body 32 and the outer rotating body 32. It arrange | positions on the axis line parallel to the axis line of the rotary body 32 so that a side surface may be opposed.

  As shown in FIG. 4, the outer gear 38 is fixed to be non-rotatable by inserting a middle portion in the length direction of the connecting pin 46 into the shaft hole 38 a opened in the axial line portion.

  For this reason, the outer gear 38 is rotatable with respect to the rotating body 32 together with the connecting pin 46. The connection pin 46 rotates together with the outer gear 38 when the outer gear 38 rotates about the axis of the connection pin 46.

  As shown in FIG. 7, linear teeth 34b, 36b, and 38b parallel to the shaft centers are formed on the outer peripheral portions of the shaft gear 34, the intermediate gear 36, and the outer gear 38, respectively. The number of teeth of the intermediate gear 36 and the outer gear 38 is 11 which is the same as the number of teeth of the shaft gear 34.

  The intermediate gear 36 and the outer gear 38 have the same pitch circle diameter as the pitch circle diameter of the shaft gear 34.

  The intermediate gear 36 is disposed between the shaft gear 34 and the outer gear 38, and the shaft center and the respective shaft centers of the shaft gear 34 and the outer gear 38 have the same length as the pitch circle diameter. Arranged to be spaced.

  For this reason, the intermediate gear 36 is formed on the outer peripheral portion thereof, and the teeth 36b mesh with the teeth 34b of the shaft gear 34 and the teeth 38b of the outer gear 38, respectively.

  When the rotating body 32 rotates as will be described later, the teeth 36b of the intermediate gear 36 mesh with the teeth 34b of the shaft gear 34 fixed to the support shaft 40 and stationary and the teeth 38b of the outer gear 38, respectively. The intermediate gear 36 and the outer gear 38 rotate (spin) around their respective axis centers.

  As shown in FIG. 3, the six support members 24 are configured as one set of two sheets, and one set (a pair) of the support members 24 is in the thickness direction (left and right direction in the figure). The inner surfaces that are perpendicular to each other are spaced apart from each other.

  And a pair of support member 24 which mutually opposes is arrange | positioned inside them so that those outer surfaces may oppose each of the outer surface of the two rotary bodies 32 arrange | positioned inside.

  As shown in FIG. 1, the support member 24 is formed in an oval plate shape having a length in the horizontal direction (left-right direction in the figure). As shown in FIG. 5, the support member 24 has a through hole 24 a at one end in the length direction (upper end in FIG. 5) and the other end (lower end in FIG. 5). A fitting hole 24b is formed.

  As shown in FIGS. 1 and 4, the support member 24 is inserted into the through hole 24 a at the other end in the length direction of the connecting pin 46 (the right end in FIG. 4), whereby the support member 24. Are arranged so that their length directions are horizontal, and are fixed so as not to rotate with respect to the connecting pin 46.

  Thus, since the support member 24 is fixed to the outer gear 38 via the connecting pin 46, when the outer gear 38 rotates about the axis of the connecting pin 46, it is integrated with the outer gear 38. It is designed to rotate (spin).

  As shown in FIG. 5, the three mass bodies 26 are arranged so as to be sandwiched inside the pair of support members 24. The mass body 26 has a sufficient mass and is formed in a cylindrical shape having an axis extending in the left-right direction in the figure and a fitting hole 26a centering on the axis.

  As shown in FIGS. 1 to 3 and 5, each of the three round bar-like support pins 48 is fitted with a pair of support members 24 in the middle in the length direction (left-right direction in FIG. 5). The holes 24b and the fitting holes 26a of the mass body 26 are inserted through the holes 24b.

  Each of the three support pins 48 has an axis that is horizontal and substantially parallel to the axis of the shaft gear 34, and is fixed to the pair of support members 24 and the mass body 26 so as not to rotate. .

  For this reason, since the mass body 26 is fixed to the outer gear 38 via the connection pin 46, the support member 24 and the support pin 48, the outer gear 38 rotates (rotates) around the axis of the connection pin 46. In this case, the outer gear 38 and the outer gear 38 are rotated together.

  As shown in FIGS. 1 to 3, the bearing member 28 is disposed so as to surround the mass body 26 and so that the outer peripheral surface of the mass body 26 is in contact with the inner peripheral surface thereof. The bearing member 28 is wound around the outer peripheral surface so that the inner peripheral surface of the belt 29 comes into contact therewith.

  One halfway (lower side in FIG. 1) of the endless length of the belt 29 is locked to an upper end portion of a coil spring 30 (biasing means) provided between the bottom plate portions 42a of the support base 42. Therefore, the mass body 26 is always pulled to the bottom plate portion 42 a side of the support base 42 via the bearing member 28, the belt 29, and the coil spring 30.

  That is, the coil spring 30 biases the mass body 26 in a direction perpendicular to the rotation axis of the mass body 26.

  As shown in FIG. 1, the coil spring 30 is integrally fixed with an adjustment member 31 having a female thread portion 31 a at the lower end thereof. The butterfly bolt 33 (bolt member) to which the male screw portion 32a is fastened to the female screw portion 31a of the adjusting member 31 is changed to a coil spring by changing the length position to be fastened to the female screw portion 31a of the adjusting member 31 of the male screw portion 32a. The force with which 30 pulls the mass body 26 can be adjusted.

  That is, since the head of the butterfly bolt 33 is locked to the locking member 43 fixed to the bottom plate portion 42 a of the support base 42, when the male screw portion 32 a is tightened to the female screw portion 31 a of the adjustment member 31, Accordingly, the length of the coil spring 30 is extended, so that the coil spring 30 acts so that the length returns to the original length.

  As shown in FIG. 10, both ends of the support pin 48 (rotation transmission means) inserted through the fitting holes 24b of the pair of support members 24 and the fitting holes 26a of the mass body 26 are teeth of the cycloid gear 62 (gear). It meshes with 62a.

  Two cycloid gears 62 are arranged on both outer sides of the pair of support members 24, and the center of rotation of the two cycloid gears 62 has a ventilation fan device 70 having an axis parallel to the axis of the rotating body 32 (separately The rotation transmission shaft 66 of the rotation device) is provided so as to be integrally rotatable.

  As shown in FIG. 10, the rotation transmission shaft 66 of the ventilating fan device 70 is provided with a drive motor 64 for driving the rotation of the rotation transmission shaft 66 at its upper end, and its lower end is driven to rotate. A fan 72 (rotated body) that operates as a ventilation fan is provided.

  Next, operation | movement of the rotation promotion apparatus 20 which concerns on one embodiment of this invention is demonstrated.

  When the rotating body 32 rotates about its axis in the counterclockwise direction in FIG. 8, the intermediate gear 36 that is rotatably supported by the rotating body 32 via the bushing 52 and the pin 44 is the axis of the rotating body 32. Centering on the heart, it makes a circular motion (revolution) counterclockwise in the figure.

  Further, the outer gear 38 that is rotatably supported by the rotating body 32 via the bush 54 and the connecting pin 46 also performs a circular motion (revolution) in the counterclockwise direction in FIG. 8 about the axis of the rotating body 32. To do.

  At this time, since the shaft gear 34 is stationary without rotating (spinning), the revolution of the intermediate gear 36 causes the teeth 36b of the intermediate gear 36 that mesh with the teeth 34b of the shaft gear 34 to be sequentially changed to different teeth. Go.

  That is, due to the revolution of the intermediate gear 36, teeth that do not mesh with the teeth 34 b of the shaft gear 34 in the teeth 36 b of the intermediate gear 36 a and new teeth that mesh with the teeth 34 b of the shaft gear 34 are formed. The intermediate gear 36 rotates (rotates) about the axis of the pin 44 in the counterclockwise direction in FIG. 9 by the amount of movement of the teeth 36b.

  Then, when the intermediate gear 36 rotates in the counterclockwise direction in FIG. 9, the teeth 36b of the intermediate gear 36 and the outer gear 38 that meshes with the teeth 38b rotate the axis of the connecting pin 46 in the clockwise direction in FIG. Rotates (rotates) as the center.

  For this reason, the support member 24 fixed to the outer gear 38 via the connection pin 46 and the mass body 26 fixed to the support member 24 via the support pin 48 are centered on the axis of the connection pin 46 as shown in FIG. Rotates (rotates) in the middle clockwise direction.

  As described above, the outer gear 38 rotates (revolves) around the connecting pin 46 in the clockwise direction in FIG. 9, and simultaneously rotates (revolves) counterclockwise around the axis of the rotating body 32.

  Here, since the shaft gear 34, the intermediate gear 36, and the outer gear 38 are formed with the same number of teeth and have the same pitch circle diameter, the circular motion of the outer gear 38 in the counterclockwise direction ( The period of (revolution) and the period of rotation in the clockwise direction (rotation) are the same.

  That is, as shown in FIG. 9, at a predetermined time interval, the angle A at which the outer gear 38 circularly moves (revolves) counterclockwise around the axis of the rotating body 32, and the outer gear 38 is connected to the connecting pin 46. The angles B that rotate (rotate) in the clockwise direction around the axis of are substantially the same.

  Therefore, as shown in FIG. 8, the support member 24 fixed to the outer gear 38 via the connecting pin 46 is opposite to the axis of the rotating body 32 in a state where the length direction is always maintained in the horizontal direction. Circular movement (revolution) in the clockwise direction.

  Therefore, the mass body 26 fixed to the left end portion of the support member 24 in FIG. 8 is indicated by a two-dot chain line centered on a position (rotation center 26 </ b> C) displaced from the axial center of the rotation body 32 to the left side in the drawing. Performs a circular motion (revolution) in the counterclockwise direction on the indicated circumference.

  As shown in FIG. 8, the mass body 26 has a weight (mass) to which a pressing force F acting downward in the vertical direction is added. Further, the position of the rotation center 26 </ b> C of the mass body 26 is disposed at a position displaced from the axial center position of the rotation body 32 to the left side in FIG. 8.

  For this reason, the sum of the rotational moments acting on the rotating body 32 by the push-down force F added by the weight of each mass body 26 produces a rotating moment acting on the rotating body 32 in the counterclockwise direction in FIG.

  As shown in FIG. 8, the mass body 26 is always pulled toward the bottom plate portion 42 a of the support base 42 via the bearing member 28, the belt 29, and the coil spring 30.

  Since the coil spring 30 is disposed below the rotation center 26C of the mass body 26, the tensile force of the coil spring 30 is distributed and applied to each of the three mass bodies 26. The push-down force F added by the weight of the mass body 26 is increased.

  Accordingly, the pressing force F applied to the mass body 26 fixed to the support member 24 generates a torque acting on the rotating body 32 at a position displaced from the axial center position, so that the rotation center of the rotating body 32 is rotated. A rotational moment can be generated around.

  Since the rotating body 32 can be rotated by this rotational moment, the rotating operation of the rotating body 32 can be promoted.

  When the rotating body 32 rotates, as shown in FIG. 10, the cycloid gear 62 is moved via the teeth 62 a meshing with the support pins 48 projecting at both ends in the length direction on both outer sides of the pair of support members 24. Can be rotated.

  Then, when the cycloid gear 62 rotates, the rotational force can be transmitted to the rotation transmission shaft 66 that drives the fan 72 of the ventilation fan device 70.

  For this reason, in the ventilation fan device 70 rotated by the drive motor 64, the rotational force generated by the rotation promoting device 20 is transmitted to the rotation transmission shaft 66 through the support pin 48, so that the rotation force of the rotation transmission shaft 66 is increased. Is promoted.

  Therefore, the rotation promotion apparatus 20 can reduce the energy used for rotation operation of the ventilation fan apparatus 70, and can reduce the cost concerning the energy.

  As described above, the rotation promoting device 20 according to the present embodiment includes the four rotating bodies 32, the shaft gear 34, the intermediate gear 36, the outer gear 38, the support member 24, and the mass body 26. And a coil spring 30, a support pin 48, and the like.

  For this reason, since the rotation promoting device 20 has a simplified shape of each component constituting it compared to the conventional rotation drive device 1, the structure can be simplified.

  Therefore, as described above, according to the rotation promoting device 20 according to the present embodiment, the structure is simple, the production cost can be prevented from being increased, and the rotating body is used for rotation. Energy can be reduced and the cost for consumption of the energy can be reduced.

  In addition, it is not limited only to the said embodiment, If it is in the range which can achieve the objective of this invention, the various change of a rotation promotion apparatus is possible.

  For example, in the rotation accelerating device 20 according to the above-described embodiment, three inner gears 36 and three outer gears 38 are supported on the inner side of the two rotating bodies 32, respectively, but it is not necessary to be limited to three. As long as they are arranged at equal angular intervals in the circumferential direction of the rotating body 32, for example, four or more may be provided.

  Further, the number of support members 24 and mass bodies 26 may be increased or decreased in order to correspond to the increase or decrease in the number of inner gears 36 and outer gears 38, and the shape of the rotating body 32 may be changed to another shape such as a circular shape. It may be changed.

  In the rotation promoting device 20 according to the above embodiment, one inner gear 36 is disposed between the shaft gear 34 and the outer gear 38, but is disposed between the shaft gear 34 and the outer gear 38. The number of the inner gears may be an odd number of 3 or more.

  In the rotation promoting device 20 according to the embodiment, the shaft gear 34, the intermediate gear 36, and the outer gear 38 have the same 11 teeth, but the outer gear 38 forms the axis of the rotating body 32. As long as the angle of circular movement (revolution) as the center and the angle of rotation (spinning) of the outer gear 38 around the axis of the connecting pin 46 are substantially the same angle, the number of teeth is not limited to 11. The number of teeth of the shaft gear 34, the intermediate gear 36, and the outer gear 38 may not be the same.

  In the rotation promoting device 20 according to the embodiment, the support member 24 is formed in an oval plate shape. However, the support member 24 is not limited to such a shape, and the support shaft 40 is not rotated during the rotation operation. For example, it may be formed in a rectangular plate shape as long as it has a length dimension that does not contact other members.

  Further, the method of fixing the mass body 26 to the support member 24 is not necessarily limited to the fixing method in the rotation promoting device 20 according to the above-described embodiment. For example, other fixing methods using screw fastening, welding, or the like. It may be fixed by.
