At present, the main transmission methods for mechanical draft cooling tower are multi-polar direct drive motor, belt type reduction drive, gear reducer drive, hydraulic turbine drive etc. Belt type reduction drive is widely application, through the tension in the pulley of the driving wheel and driven wheel belt for the power transfer to a mechanical transmission, it has a simple structure, stable transmission, can buffer vibration absorption, can be in large axial spacing between shaft and transmission power, low cost, without lubrication, easy maintenance and other characteristics, widely used in the cooling tower and a number of mechanical equipment.
