  • Patent number: 5497684
    Abstract: A guiding system for large circular saws wherein the guiding pads are positioned according to a typical angular wavelength of a circumferential vibration wave of the saw blade when rotating at an operating speed. In one embodiment, the frequency of a natural circumferential vibration wave is measured before positioning the guiding pads. Two sets of guiding pads are spaced apart a distance equal to about half the angular wavelength of such natural vibration wave. This distance corresponds to an angular distance between two successive opposite peaks or crests of a sinusoidal wave in the saw blade. The consequence of two successive opposite peaks entering the guiding pads at the same time has the effect of dampening the vibration very quickly, by acting upon both sides of the blade simultaneously to reduce the amp amplitude of the wave, while maintaining balanced axial impact on the saw.
