め潤滑油がピンの部分に入りにくい欠点がある。 A silent chain is a type of chain that reduces meshing noise by eliminating the collision noise of rollers or bushings of roller chains and bushings against the sprocket tooth bottoms. In conventional silent chains, each link plate forms a tooth profile that slides into the teeth of the sprocket, so many link plates must be stacked on top of each other, making the chain unnecessarily heavy and reducing the chain's power transmission. This has a negative effect on efficiency and vibration. Also, since the link plates are stacked one on top of the other, lubricating oil is difficult to get into the pin area.

る。 The present invention aims to eliminate the above-mentioned drawbacks of the conventional silent chain, and uses two pins with symmetrical cross-sectional shapes to connect the outer link and
The present invention is characterized in that the inner links are connected so that the outer surfaces of each of the pins mesh with the tooth surfaces of the sprocket.

ようにするための穴５が設けられている。 Embodiments of the present invention will be described below based on the accompanying drawings. As shown in FIGS. 1 and 2, a long pin 3 is caulked to an outer link 1, and a short pin 4 is inserted to an inner link 2. ing. A hole 5 is provided in the inner link 2 so that the long pin 3 can freely rotate when the chain is bent.

限定されるわけではない。 As shown in Figure 1, the long pin 3 and the short pin 4 have symmetrical cross-sectional shapes, and in the case shown in Figure 1, they have an elliptical cross section, but the shape is limited to an ellipse. It's not like that.

く低減される。 FIG. 2 shows the state in which the silent chain of the present invention is wound around a sprocket. The side surface of the short pin 4 slides into contact with the side surface of the teeth 6 of the sprocket, and the long pin 3 is also rotatable due to the presence of the hole 5, so its outer surface contacts the teeth of the sprocket. It slides into contact with the side of 6. Therefore, the noise generated when the chain and sprocket engage is significantly reduced.

めて少ない効果を有する。 In the present invention, as described above, the side surfaces of the two pins mesh with each other so as to slide into the tooth surfaces of the sprocket, so collisions during meshing are significantly reduced. Furthermore, since the number of stacked link plates is not as large as in conventional silent chains, the weight of the chain is significantly reduced. Therefore, collision noise during meshing is reduced, and transmission efficiency is improved. Also, since lubricating oil can easily enter between the two pins, wear on the pins is extremely low.
