DEVICE FOR REDUCING THE NOISE AND VIBRATIONS OF DISK SAWS Russian patent published in 1995 - IPC

FIELD: wood-working industry. SUBSTANCE: vibration-absorbing cover of round shape made composite of alternating, different in thickness metallic layers and the non-metallic layers of vibration-absorbing materials is pressed by flanges in the device at least on one side of the disk saw. In this case the thickness of the vibration-absorbing cover makes up 10-500 of the thickness of the disk saw. Its radius differs from that of the saw disk at least by the depth of the saw cut. The layers of which the vibration-absorbing cover consists, differ from each other in thickness not more than by a factor of 10³. The layer of vibration-absorbing cover adjoining the disk saw is made of viscoelastic material. The exterior layer of the vibration-absorbing cover is made of metal with the thickness greater than any of the rest of the metallic layers of the cover. The device is used in machine tools with disk or circular saws for processing wood, stone and metal. EFFECT: reduced level of noise and vibrations. 3 cl, 1 dwg
