Title:
METHOD AND MECHANISM FOR INCREASING CRITICAL SPEED IN ROTATING DISKS AND REDUCING KERF AT HIGH SPEEDS IN SAW BLADES
Document Type and Number:
WIPO Patent Application WO/2005/108032
Kind Code:
A1
Abstract:
There is provided a method for increasing the critical speed of a rotating disk and disk using same. The method comprises the steps of providing a disk and fastening at least one heat sensitive insert to the disk. The insert exerts a tensile stress on the disk when an insert temperature exceeds a redetermined temperature. The disk could be a saw blade. Also, there is provided a saw blade and method having a reduced kerf at high speeds, the blade having a serrated cutting edge. The blade comprises at least one insert attached to the blade, the at least one insert exerting a tensile stress on the blade when an insert temperature reaches a predetermined temperature, the exerted tensile stresses opposite to those induced by the blade temperature.
