た。Figure 7 shows an Oldham type shaft coupling that has been used since ancient times. This shaft joint is constructed by combining a disc having one-letter protrusions on both sides at right angles to each other, and a flange having a one-letter groove on both sides of the disc to fit with the one-letter protrusions. In this case, if there is eccentricity of the shaft, the protrusion absorbs this while sliding in the longitudinal direction within the groove. Therefore, the intermediate disc and the flanges on both sides slide against each other and operate in a complicated manner, generating a large reaction force in the radial direction, which causes the driven side to swing significantly, and is not suitable for high-speed rotation. Furthermore, since each component consists of three different types of discs, assembly, disassembly, and maintenance are troublesome, and there is a risk of parts being lost.
第８図は板ばね式の軸継手である。この構造のものでは

もある。Figure 8 shows a leaf spring type shaft joint. With this structure, slight eccentricity and deviation can be absorbed by the deflection of the leaf spring, but the tension of the leaf spring generates a reaction force in the radial direction, similar to the Oldham type shaft coupling. Another problem is that the degree of freedom in the axial distance between the driving side and the driven side is extremely small.
第９図はコイルばね式軸継手であるが、この形式のもの
も板ばね式のものと同様の特性のものである。FIG. 9 shows a coil spring type shaft joint, and this type has the same characteristics as the leaf spring type.

トルクが大きい程弾性率を大きく（硬く）シなければな
らないため、反力も伝達トルクに比例して大きくなる。FIG. 10 shows a tire-shaped rubber joint. With this structure, there is a relatively large degree of freedom in the axial distance between the driving side and the driven side, but since the absorption of eccentricity and declination angle depends on the elastic modulus of the rubber, a considerable reaction force in the radial direction is generated. . That is, the greater the transmitted torque, the greater (harder) the elastic modulus must be, so the reaction force also increases in proportion to the transmitted torque.

自由度が少なく、取付は精度、保持構造に特別の注意を
必要とした。As described above, in conventional shaft couplings, a large reaction force is generated in the radial direction, and there is little freedom in the axial distance between the driving side and the driven side, and special attention is required to the mounting accuracy and holding structure. did.

と共に、全ての変位はリンクの僅かな回転により行われ
るので、動きが滑らかでありラジアル方向の反力は極め
て小さくなる。According to the invention of claim 1, since the first, second, and third members are each connected by a link, the first member and the second member can be displaced in a direction perpendicular to the ring within a rotatable range by the link. The same applies between the second member and the third member, and the first
Between the member and the third member, these two possible displacement ranges are synergistically wide (displacement is possible in one range, and as a result, a large amount of eccentricity is allowed between the driving side and the driven side, and Since all displacements are performed by slight rotations of the links, the movement is smooth and the reaction force in the radial direction is extremely small.

Since it can slide in the axial direction, the accuracy of installation positions on the driving side and the driven side is relaxed.

The gap is smaller, the first member can be the driving or driven member itself, for example a gear, and the drive transmission system is further miniaturized.
