New Criteria for Air Conditioning Belt Drive Design 710546

Belt drives are simple and efficient and are widely used, but they are very often a source of vibration and noise.

Herein, an analytical method is presented which allows the designer to approach this objective in the initial design stages. It is shown that a number of variables such as torque characteristics, belt span, belt material and construction contribute to the objectionable noise.
