CIRCULAR SAW BLADE WITH REDUCED NOISE

摘要

The invention involves the reduction of the noise from rotary saw disks so that the vibrations are dampened according to the frequency of the disks. The invention is based on the fact that from one or both sides of the side area of a disk (1) a bed (5) is created with a radius of 0.3 to 0.9 of the radius of the foot circle of the teeth (R2) as semi-circles where the dampening foil (6) is placed either by sealing or in another method using sheet metal or other materials or the foil (6) is created in the bed by spraying or pouring on metal or another substance with a higher density. It is also possible to create a saw disk (1) with a thickness divided into two half parts (7) and insert a Teflon or other internal dampening foil (6) into the inside parts of the beds (5), while both parts (7) of the disk are firmly joined at points outside the foil area, for example, by point welding.<IMAGE>
