Abstract
An improved tensioning device is provided for use in an inner diameter saw blade housing. A tensioning ring, disposed in an annular clamping member, is internally threaded at plurality of locations along its circumference. An associated plurality of screws, disposed in cylindrical recesses in the clamping member, threadedly engage the internal threads. The screws may be turned through an opening in the clamping member having a diameter smaller than the screw to thereby precisely tension the blade as desired. Since the screws are captive within the clamping member, migration of the tensioning ring relative to the blade is prevented. Further, the screws do not protrude from the surface of the clamping member and the threaded portions of the screws are closed off from the ambient such that foreign matter cannot enter the clamping member and interfere with the tensioning process.
