収容されている。 Next, one embodiment of the present invention will be described with reference to the drawings. In Figs. 1 and 2, 1 is a joint center, around which a joint flange 2 is fitted with an O-ring 3 (see Fig. 2). The joint center 1 and the joint flange 2 are each connected to separate shafts (not shown). A cavity 4 is formed in the joint center 1 and the joint flange 2, and a plurality of disc springs 5 are housed inside the cavity 4.

る。 As shown in FIG. 3, these plurality of disc springs 5 are arranged with their centers aligned in a straight line and are disposed in contact with each other, and spring seats 6 and 7 are disposed in contact with each other on both sides. A sealed internal space 8 is formed by the disc spring 5 and the spring seats 6 and 7 which are arranged in contact with each other. The spring seats 6 and 7 are respectively provided with protrusions 9 and 10 that protrude into the internal space 8, and a guide spring 11 whose both ends are fitted into the protrusions 9 and 10 is disposed. There is.

リフイス１６が設けられている。 As shown in FIG. 2, the joint center 1 is provided with an oil supply hole 12 and the joint flange 2 is provided with an oil release hole 17, so that the inside of the cavity 4 is always filled with oil and circulates. ing. A check valve 13 is attached to one of the spring seats 6, and an oil inflow passage 14 communicating from the check valve 13 to the internal space 8 is provided. The check valve 13 is configured to allow oil to flow only toward the internal space 8 and to prevent oil from flowing in the opposite direction. The other spring seat 7 has an oil outflow passage 15 that opens into the internal space 8, and an orifice 16 is provided on the outlet side of the oil outflow passage 15.

衰されることになる。 In the above-mentioned device, when torque fluctuation occurs between two shafts (not shown) due to torsional vibration, when the disk spring 5 is extended and the volume of the internal space 8 is increased, the cavity 4 (see FIG. 1) ) enters the internal space 8 through the check valve 13 and the oil inlet passage 14. Next, when the disc spring 5 is compressed and the volume of the internal space 8 is reduced, the oil in the internal space 8 passes through the oil outflow passage 15 and the orifice 16 and is discharged in a constricted state. As a result, torsional vibrations are damped.

久性が増す効果がある。 In conventional disc spring type flexible shaft joints, there was no oil passage provided in the spring catch, and the only thing to do was to apply grease to the disc spring and the spring catch.
Although a damping effect on torsional vibration could not be expected, the present invention allows oil to flow into the internal space formed by the disc spring and the spring seat through a check valve, and to flow out through an orifice. This makes it possible to attenuate torsional vibrations due to oil resistance during spillage. Furthermore, since this oil always provides a lubricating effect to the disc spring and the spring seat, durability can be increased even without applying grease.
