る。Conventional Technology Conventionally, when connecting rotating shafts to each other, if the axes of both rotating shafts are misaligned, a force in a direction perpendicular to the axes acts on the axes, creating resistance between them and the bearings, which prevents smooth rotation. A universal joint is used to connect rotating shafts that are likely to be misaligned due to interference.

遮断し得るクラッチが用いられている。If there is a risk of overload being applied to the rotating shaft on the driven side, in order to prevent damage to the drive source of the rotating shaft on the driving side, transfer the rotational force between the rotating shaft on the driven side and the rotating shaft on the driving side at the time of overload. A clutch is used that can cut off the

。If it is necessary to move the driven side rotating shaft forward or backward depending on the direction of rotation, the driven side rotating shaft is formed into a feed screw, and the connecting part between the base and the driving side rotating shaft is formed with a keyway. It has a spline configuration consisting of a combination with a key.

しめた場合、従動側の回転軸に過負荷がかかった状態が
持続すると駆動側回転軸の駆動源が破損するおそれがあ

しめることは不可能である。Problems to be Solved by the Invention When a conventional universal joint is used, if an overload continues to be applied to the driven side rotating shaft, the drive source of the driving side rotating shaft may be damaged. However, it is also impossible to move the driven-side rotating shaft forward or backward depending on the direction of rotation.

は矢張り不可能である。When using a clutch, if the axes of both the driven and driving shafts are misaligned, smooth transmission of rotational force will not be possible, and it will be impossible to move the driven shaft forward or backward. It is possible.

損するおそれがある。When using a spline joint, if the axes of both the driven and driving shafts are misaligned, smooth transmission of rotational force will not be possible, and overload will be applied to the driven shaft. If the condition persists, there is a risk that the drive source of the drive side rotating shaft will be damaged.

ことが可能となるが、継ぎ手の総合軸長が徒に長くなる
を免れることが出来ない。In addition to connecting traditional universal joints, clutches, and spline joints,
By forming the driven-side rotating shaft of the spline-structured joint with a feed screw, the axis of the driven-side rotating shaft of the spline-structured joint and the axis of the driving-side rotating shaft of the universal joint can be aligned. Even if the rotational force is misaligned, the rotational force is transmitted smoothly, and if an overload is applied to the final stage rotating shaft, the coupling of the clutch is broken and the drive source is prevented from being damaged, and the rotation of the driven side of the spline joint is prevented. Although it is possible to move the shaft forward and backward depending on the direction of rotation, the total shaft length of the joint is unnecessarily long.

is rotated, and when either the sphere 18+ or 182, for example 182, fits into the groove 5 provided in the axial direction on the inner peripheral surface of the joint body l as shown in FIG.
With the rotation of the joint main body 1, the joint body 1 rotates, causing the movable needle 23 in the flow rate adjustment device to rotate.
可動針２３は、その回転方向に応じて前進又は後退し、
流入口２０から流入し流出口２１から流出する流体の流
量を調整する。The movable needle 23 moves forward or backward depending on its rotation direction,
The flow rate of fluid flowing in from the inlet 20 and flowing out from the outlet 21 is adjusted.

When the movable needle 23 is overloaded, the connection between the sphere 182 and the groove 5 in the universal joint of the present invention is broken, the movable disc 10 idles, and the transmission of rotational force is cut off. Rotatable i
Even if the ball 181 continues to idle and the ball 181 fits into the groove 5, the resistance of the joint body l against the rotational force is large, so the ball 18
1 and the groove 5 is immediately broken, and the movable disk 10 continues to idle. From then on, the movable disk 10 continues to idle in the same way, and the transmission of rotational force to the movable needle 23 is cut off, causing the fluid to flow. When the flow rate decreases below the set value and the overload on the movable needle 23 is removed, the rotational force is transmitted again.

By appropriately determining the diameters of the grooves 182 and 182, the depth and width of the grooves 5, etc., the transmission of rotational force can be cut off and restarted reliably and quickly in the event of an overload.

, spheres 18+ and 182, and are also rotatable around this support shaft, even if the axes of the drive rotation shaft 31 and the movable needle 23 are misaligned in any way. Even in this case, smooth transmission of rotational force is not hindered.

発明自在継ぎ手を用いた場合につき説明したが、一般の
回転軸への回転力の伝達に用い得ること勿論である。The above description has been about the case where the universal joint of the present invention is used to transmit the drive rotational force for adjusting the fluid flow rate by controlling the forward and backward movement of the movable needle in the flow rate adjustment device. Of course, it can be used to transmit force.

めることによって目的を達することが出来る。In addition, by adjusting the axial length of the joint body l and the difference between the inner diameter of the joint body l and the outer diameter of the movable inner part g110, the rotational force can be maintained at all times regardless of any misalignment of the rotating shafts on the driving side and the driven side. As mentioned above, if the displacement is large, the difference between the inner diameter of the joint body l and the outer diameter of the movable disk lO will be increased, and the movable inner g1
The objective can be achieved by increasing the thickness of sphere 10 and the diameters of spheres 181 and 182.

。As shown in FIG. 5, when one groove 5 is provided on the inner peripheral surface of the joint body l, a sphere 18! Or, if the drive source is started while none of the spheres 182 are fitted into the groove 5, either the sphere 1B or 182 will fit into the groove 5 and transmit the rotational force to the joint body l. The maximum angle at which the movable disk 10 rotates idly is close to 180 degrees, and there is a slight delay in time until the rotational force begins to be transmitted.

割した個所に設けである。FIG. 1O is a rear view showing the main parts of an embodiment capable of shortening the delay time for the start of transmission of rotational force, and 51 to 53 are the same as the grooves 5 shown in FIG. These are grooves provided in the surface, and are provided at locations where the inner circumferential surface of the joint body 1 is divided approximately equally in the circumferential direction.

1 or 182 is not fitted into any of the grooves 51 to 53, the maximum idling angle of the movable disc 10 is 60°.
Therefore, the delay time for starting transmission of rotational force can be shortened.

し得る等の特長を有する。Effects of the Invention The universal joint of the present invention has an extremely simple and compact structure, is easy to manufacture, and is free from any misalignment of the axes of the driving-side rotating shaft and the driven-side rotating shaft, that is, translational misalignment in any direction. Or, it is possible to smoothly transmit the rotational force regardless of diagonal deviation in any direction or fluctuations in the mutual spacing of the rotating shafts. By cutting off the transmission of rotational force and adjusting the elasticity of the spring 15 built into the movable filO, it is possible to respond to overloads of different magnitudes, which eliminates the need for conventional universal joints, clutches, and spline configurations. In addition to having all the functions of a joint,
In the case of a rotating shaft in which the driven-side rotating shaft moves forward and backward in the axial direction depending on the rotation direction, the joint body l must be manually rotated in the forward and reverse directions before the driving-side rotating shaft starts rotating. This has the advantage that the initial position of the rotating shaft on the driven side can be arbitrarily set.
