ABSTRACT:
A vibration resistant band wheel for band saw machines wherein an endless cutting band is customarily trained in tension around the peripheral surfaces of spaced band wheels with the back edge of the cutting band acting against a flange extending radially outward from the rear face of the band wheels and the cutting edge of the cutting band overhanding the non-flanged front face of the band wheels. A tire of resilient material is fitted on the peripheral surface of a band wheel having a disc shaped body such that the resiliant material tire lies between the band wheel flange and the non-flanged front face. A metallic cutting band contact tire is fitted on the peripheral surface of the band wheel over the resilient material tire with one edge of the contact tire adjacent the band wheel flange, thereby providing a metallic contact surface for engaging the cutting band. Retainer plates act to hold the resilient material tire and the contact tire on the peripheral surface of the band wheel. Vibrations in the cutting band resulting from cutting operations are transferred to the contact tire, and are absorbed or dampened by the resilient material tire, and thus, are prevented from reaching the band wheel disc shaped body, and causing band wheel noise.
