  • Plate for a silent chain
    Patent number: 6045473
    Abstract: A plate for a silent chain has a side punched into a forked shape for engagement with a sprocket. The forked side of the plate has inner engaging surfaces opposing each other, outer engaging surfaces, and an arcuate leg-side end surface connecting the inner engaging surfaces. The leg-side end surface, on which stress is likely to be concentrated, has a shear face tissue along at least 70% of the thickness of the plate. A silent chain having such a plate has a high plate fatigue strength and enhanced durability and reliability, and can be manufactured at a low cost.
