A double-meshing-type silent chain includes link plates having the identical side profile. Each link plate has two meshing teeth and a flat back face formed opposite to the meshing teeth. Two kinds of links are alternately arranged in the longitudinal direction of the chain, while the adjacent links are connected by pins. In one kind of link, an odd number of the link plates are disposed in the width direction of the chain. In the other kind of link, an even number of the link plates are disposed in the width direction of the chain. In each link, the link plates are oriented such that the meshing teeth of link plates located at widthwise opposite ends project outwardly with respect to the chain and the meshing teeth of the remaining link plates project inwardly with respect to the chain.

1. Field of the Invention
The present invention relates to a double meshing-type silent chain capable of meshing with sprockets located inside and outside the chain and to a sprocket for meshing with the chain along the outer circumference thereof.
2. Description of the Related Art
Various other objects, features and many of the attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description of the preferred embodiments when considered in connection with the accompanying drawings, in which:
FIG. 1 is a side view showing an embodiment of a double-meshing-type silent chain according to the present invention;
FIG. 2 is a plan view showing the double-meshing-type silent chain of FIG. 1;
Embodiments of the present invention will next be described in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of a double-meshing-type silent chain according to the present invention. FIG. 2 is a plan view of the silent chain. In FIGS. 1 and 2, a double-meshing-type silent chain (hereinafter, referred to simply as a chain) 1 includes link plates 2A, 2B, 2C, and 2D having the identical side profile.
The link plates 2A, 2B, 2C, and 2D each have two meshing teeth T and a flat back face S formed opposite to the meshing teeth T. The meshing teeth T have a tooth profile similar to that of a standard silent chain.
In the chain 1, two kinds of links are alternately arranged in the longitudinal direction of the chain 1, while the adjacent links are connected by pins 3. One kind of link is composed of an odd number of link plates, specifically three of link plates 2C and two of the link plates 2A which are disposed such that the three link plates 2C are interposed between the two link plates 2A. The other kind of link is composed of an even number of link plates, specifically two of the link plates 2D and two of the link plates 2B which are disposed such that the two link plates 2D are interposed between the two link plates 2B.
