である。[Detailed description of the invention] This invention relates to a shock-absorbing coupling that uses a coil spring. When one end of the coil spring is fixed and the other end is twisted in the direction of curling, the coil diameter becomes smaller, and vice versa. When twisted in the return direction, the coil diameter increases to ensure power transmission, and in the event of a sudden stop on the input shaft side, braking is applied to reduce impact. be.
以下その詳細を図面の実施例について説明する。The details will be explained below with reference to the embodiments shown in the drawings.

ジ２に夫々係着してなることを特徴とするものである。The buffer coupling according to the present invention includes a connecting shaft 5 in which a flange 2 connected to an input shaft 1 and a flange 4 connected to an output shaft 3 are fixed to the flange 4 on the output shaft 3 side, and a predetermined outer circumference of the connecting shaft 5. The coil spring 7 is loosely fitted and connected by a hollow cylinder 6 provided concentrically with an annular space a, and the coil spring 7 is wound around the connecting shaft 5 in the annular space a between the flanges 2 and 4. One end 7 of the coil spring 7 is provided.
It is characterized in that the end 7a is connected to the output shaft side flange 4, and the other end 7b is connected to the input shaft side flange 2.

フランジ２，４を掌合しねじ１２で結合することにより
両軸１，３を同一軸芯上に結合するものである。The input shaft 1 and the output shaft 3 are pivotally supported in abutting manner,
A flange mounting body 8° 9 is attached to each shaft of both shafts 1 and 3 by screws or keys, and this mounting body 8 and 9 and the flanges 2 and 4 are connected with a screw 12 that fits together. By doing so, both shafts 1 and 3 are connected on the same axis.
連結軸５はその基端部を一方のフランジ４の内面中央に
一体に固着され、先端部は他方のフランジ２にベアリン
グ１３等を介して軸支されるようにする。The connecting shaft 5 has its proximal end fixed integrally to the center of the inner surface of one flange 4, and its distal end is pivotally supported by the other flange 2 via a bearing 13 or the like.
コイルスプリング７は自然長の状態で環状空間ａの中間

筒６の内周面６ａに接触しないようにしである。The coil spring 7 is wound around the middle part of the annular space a in its natural length so that it does not come into contact with the outer circumferential surface 5a of the connecting shaft 5 and the inner circumferential surface 6a of the hollow cylinder 6 when the coil spring 7 is stopped.

軸３に伝達される。In the above configuration, the input shaft 1 is connected to a drive device such as a motor (
(not shown) to twist the coil spring 7 in the direction of compression (in the direction of arrow A), the rotation of the input flange 2 causes the coil spring 7 to twist in the direction of contraction, reducing the coil diameter. The output shaft 3 is tightly wound around the outer circumferential surface 5a of the connecting shaft 5, and is integrated with the input shaft 1 via the coiled spring 7, so that the rotation of the input shaft 1 is transmitted to the output shaft 3.

は急速に停止する。Furthermore, when the input shaft 1 is stopped, the output shaft 3 rotates due to inertia, but since the end 7b of the coil spring 7 is engaged with the stopped input end flange 2, the spring 7 is twisted in the unwinding direction. Therefore, the coil diameter becomes large and the outer diameter part 7d of the coil spring becomes the inner peripheral surface 6a of the hollow cylinder.
Since it is pressed against the output shaft 3, braking is applied to the output shaft 3.

き付けて停止させるようにする場合もある。In addition, although the case where the input shaft is rotated in the coiling and contracting direction of the coil spring is shown, the rotation is transmitted to the output shaft by rotating the input shaft in the unwinding direction and pressing the outer diameter part of the coil spring against the inner peripheral surface of the hollow cylinder. However, when the vehicle is stopped, a coil spring may be wound around the connecting shaft to stop the vehicle.

達し得るので幅広い用途に利用できる。Since the present invention has the above-mentioned configuration, when the input shaft is rotated in the positive direction, which is the coil spring's coiling and contracting direction, the coil diameter of the coil spring becomes smaller and wraps around the connecting shaft, and when rotational force is applied, the coil diameter increases. Strong and reliable power transmission to the output shaft is achieved through close contact, and when rotating in the opposite direction, which is the unwinding direction of the coil spring, the coil diameter increases and is pressed against the inner circumferential surface of the hollow cylinder, resulting in a strong and reliable power transmission to the output shaft. In order to transmit rotation to the output shaft, even if the input shaft is rotated in either the forward or reverse direction, the rotation force can be reliably transmitted to the output shaft by the coil spring that expands or contracts the diameter, and the connecting shaft or hollow cylinder. If the rotation of the input shaft is stopped or braked during transmission, the coil spring will be unwound in the case of forward rotation, and the coil diameter will increase and be pressed against the inner peripheral surface of the hollow cylinder, and in the case of reverse rotation, the diameter will be reduced. Since the coil spring wraps tightly around the connecting shaft, braking is applied to the output shaft, making it possible to stop the output shaft with less impact. Since braking can be performed as a buffer using the expansion and contraction of the coil spring, there is no strain on the transmission, and silent and smooth operation can be achieved.Rotation can be transmitted regardless of whether the input shaft rotates in the forward or reverse direction. It can be used for a wide range of purposes.
而も両軸の接合部分に固定支持部を必要としないので、
軸接手として利用でき、構造も簡単で耐久性があり、安
価に実施できる。Moreover, since there is no need for a fixed support part at the joint of both shafts,
It can be used as a shaft joint, has a simple structure, is durable, and can be implemented at low cost.
