Abstract: Effects of the bearing span and backless on the noise of a gear system are experimentally investigated. The apparatus is composed of a driving motor, a steel master gear on a drive shaft, tested plastic (poly-acetylene) and steel gears attached on driven steel shaft. The tested gear is made of Poly-acetylene resin. The Fast Fourie Transform (FFT) is performed to analyze with operating these gears in the speed range of 450~3000rpm under no load, truly, both noise and vibration of the gear system. The main frequency components are clearly obtained through the FFT technique.
Keywords: Noise, plastic gear, bearing span and shaft center distance
