Reduction of Vibrations and Noise using Nylon-66/Al2O3 Nanocomposite Gear Box in Lathe

Exposure to excessive noise can damage hearing, and it is important to understand the effects of this kind of noise, particularly because such exposure is avoidable. The aim of the present work was to reduce vibrations and noise in the lathe machines using nylon-66/Al2O3 nano composite gears in the gear box. As per IRD General Machinery Vibration Severity Chart, the condition of the lathe is VERY SMOOTH as the vibration has been reduced to 85 VdB. The noise levels have been reduced to the permissible limit of 97 dB for the lathe machines with gear box having Nylon-66/Al2O3 nano composite gears.
