Abstract
The present invention relates generally to shredder noise reduction. Specifically, this invention discloses shredder motor gears and belts which are coated with a dampening material to reduce noise. When belt assemblies are used to couple the motor to the rotary cutting shafts, a pronounced decrease in noise is found. Additionally, the invention discloses the placement of vibration absorbers between the motor assembly and the shredder housing, as well as the rotary cutting assembly and shredder housing, thus further facilitating noise reduction.
