Research on Noise Test of Chains with Non-Metallic Elastic Material Split Rollers
In order to reduce chain drive noise, by changing chain roller structure to mitigate meshing impact and achieve the purposes of noise reduction, a kind of duplex chains with non-metallic elastic material split rollers was designed. To study noise performance of the chains, noise comparison test was done on the same specifications duplex roller chains, and the test results were analyzed and evaluated. The results showed that duplex chains with non-metallic elastic material split rollers could reduce the meshing impact and the polygon effect, which could effectively reduce vibration and noise in the process of chain drive. So the design was reasonable and feasible, noise level was reduced by 3-8dB and a significant noise reduction was achieved.
