Abstract: A new method for controlling noise and vibration of reducer is introduced in this paper. If stability factor S, is less than 1, noise and vibrition will occur with the reducer, If Sr>1, the reducer will not noise and vibrate. The calculation and the experimental results were compared. The validaty of the method suggested in this paper is confirmed by the experimental results.
