  More specifically, the relationship of the connecting positions of the lever rod portion 18 will be described. When the predetermined position where one end of the lever rod portion 18 is connected is located at the uppermost portion of the power point rotating body portion 12, The predetermined position to which the other end of the rod portion 18 is connected is located at the lowermost portion of the action point rotating body portion 14 and has the opposite positional relationship.

The fulcrum bearing portion 16 includes a bearing housing 60 and a bearing portion 62. The fulcrum bearing portion 16 can be formed using a material having an appropriate strength, such as cast iron or stainless steel.

  The fulcrum bearing portion 16 includes a bearing housing 60 and a bearing portion 62. The bearing portion 62 is a substantially cylindrical member having a substantially donut shape in which the lever rod portion 18 is inserted into the through hole 64 and having a curved convex portion 67 on the outer peripheral portion.

The force point side distance D ₂ between the fulcrum bearing portion 16 and the force point rotating body portion 12 is made larger than the action point side distance D ₁ between the fulcrum bearing portion 16 and the action point rotating body portion 14.

  The pulley 40 is a pulley provided between the bearing portion 36 and the bearing portion 38. The pulley 40 is penetrated by the action point rotating shaft 34 and rotates in conjunction with the rotation of the action point rotating shaft 34. A string portion 24 is wound around the pulley 40, and a weight 4 having a predetermined weight M is suspended from the tip of the string portion 24.

  Next, the operation of the rotary insulator device 10 having the above configuration will be described. Here, in the weights 2 and 4 suspended from the string portions 22 and 24, the weight m of the weight 2 is set lighter than the weight M of the weight 4.

Here, if the ratio of D ₁ and D ₂ is set to a relationship of 1: 5, for example, if m = 1 kg and M = 5 kg are set, a balance can be obtained. Therefore, by setting m = 2 kg, the weight of the weight 2 is won and the weight 2 is lowered.

  When the weight 2 is lowered and the power point rotating body portion 12 is rotated, one end of the lever rod portion 18 is turned along the outer periphery of the power point rotating body portion 12. The other end of the lever rod portion 18 is turned along the outer periphery of the action point rotating body portion 14 in conjunction with the rotation of the power point rotating body portion 12.

  The pulley 40 rotates in conjunction with the rotation of the action point rotating body portion 14 and the string portion 24 is wound up. Thereby, the weight 4 is lifted. As described above, according to the rotary insulator device 10, the weight 4 that is heavier than the weight 2 can be lifted using the weight 2.

  FIG. 3 is a perspective view of the rotary lever device 11 which is a second example of the embodiment according to the present invention. FIG. 4 is a front view of the rotary lever device 11.

  The rotary insulator device 11 is a modified example of the rotary insulator device 10, and the difference is that an electric motor 42 and a generator 44 are used instead of the weights 2 and 4. Therefore, the difference will be mainly described. The description of common parts is omitted.

  In the rotary lever device 11, belts 47 and 55 are wound instead of the string portions 22 and 24 that remove the weights 2 and 4.

  The electric motor 42 is a motor that supplies power for rotating the power point rotating body 12. A pulley 46 is mounted on the rotating shaft of the electric motor 42, and a belt 47 is attached across the pulley 46 and the pulley 48.

  Here, the diameter of the pulley 48 is set to be larger than the diameter of the pulley 46 because the output torque is increased by lowering the rotational speed of the pulley 48, that is, the power point rotating body portion 12. Because.

  When the electric motor 42 is operated using a power source (not shown), the rotation of the pulley 46 is transmitted to the pulley 48 via the belt 47, and the power point rotating body 12 is rotated.

  The power generator 44 generates electric power using the rotational force of the action point rotating body 14 that is linked to the rotation of the power point rotating body 12. A belt 47 is attached across the pulley 54 and the pulley 40 that are connected to the rotary shaft 51 that is connected to the rotor of the generator 44. On both sides of the pulley 54, bearings 50 and 52 of pillow type bearing units through which the rotary shaft 51 passes are provided.

  The reason why the diameter of the pulley 54 is set smaller than the diameter of the pulley 40 is to make the rotational speed of the pulley 54 faster than that of the pulley 40.

  Here, for example, the size of the pulley 46 is preferably 3 inches in diameter, and the size of the pulley 48 is preferably 8 inches in diameter, so that the diameter ratio is preferably 3: 8. Further, the size of the pulley 54 is preferably 2.5 inches in diameter, and the size of the pulley 40 is preferably 7 inches in diameter.

  For example, if the motor 42 having a standard of 750 W, 1 horsepower, and 1730 rotations is used, the rotational speed on the power point rotating body 12 side is in consideration of the ratio of the pulleys 46 and 48 being 3: 8. 1730 ÷ (8 ÷ 3) = 648 rotations.

  The number of rotations on the generator 44 side is 648 × (7 ÷ 2.5) = 1814 rotations considering that the ratio of the pulleys 40 and 54 is 2.75: 7.

  Then, the effect | action of the rotary insulator apparatus 11 of the said structure is demonstrated. When the motor 42 is operated using a power source (not shown), the power point rotating body 12 rotates through rotation of the pulleys 46 and 48.

  When the force point rotator 12 rotates, the action point rotator 14 rotates via the lever rod 18, and the pulleys 40 and 54 rotate in conjunction with this. When the pulley 54 rotates, the rotor of the generator 44 rotates, whereby the generator 44 generates power.

  Here, the generator 44 determines the generated power by a relational expression of P (electric power) = ω (including the rotational speed) × T (torque), and the rotary insulator device 11 can increase the torque.

According to the rotary insulator device 11, there is an advantage that the power generation efficiency in the generator 44 can be increased by adjusting the distances D ₁ and D ₂ of the insulator rod portion 18 to increase the torque.
