  • Publication number: 20080167151
    Abstract: In a link plate for a silent chain, outer flanks of the teeth have a protruding surface and a retracted surface, the protruding surfac and the retracted surface being connected by a step, and the protruding surface being farther than the retraced surface from the back of the link plate. Both the protruding surface and the retracted surface comprise straight portions, and, preferably, the protruding surface is shaved, whereas the retracted surface is not shaved.

  • Patent number: 7117575
    Abstract: In manufacturing a link plate for a roller chain, a band of sheet steel is intermittently forwarded along a path past series of dies, including rough punching dies and shaving dies. The punching dies and corresponding shaving dies are located symmetrically on opposite sides of an intermediate location along the path. The intermediate location coincides with a location at which the lateral deviation of the band reverses. Consequently, the outer peripheral surfaces of the plate and the inner peripheral surfaces of the connecting pin holes, both being formed by rough punching, are brought into very close alignment with the shaving dies.
