                                                • Common solution to the noise of synchronous belt wheel
                                                  Noise control mainly from two aspects: one is from the source to find ways that eliminate or weaken the intensity of the sound source, which is the fundamental method of noise control, is also the focus of this discussion; two is to take measures such as sound absorption and insulation from the transmission of noise, transmission or noise shielding to.
                                                • Control of aerodynamic noise
                                                  In the case of high speed rotating pulley, belt and high frequency gear wheels to enter or exit the engagement state, so that the alveolar air at the compression or diastolic disturbance causing air noise generated.
