Belt transmission mechanism for cooling tower blower

The utility model provides a belt transmission mechanism for a cooling tower air feeder, which uses a flat belt as a transmission belt for the air feeder, can be properly provided with a tension adjusting part for inhibiting the bending of the belt to prevent the belt from falling off, and realizes maintenance-free and efficient impeller driving. Specifically, a flat belt is used as a transmissionbelt (13) wound between a drive-side pulley (11) and a driven-side pulley (12). A tension adjusting part (14) for keeping the belt (13) inflexible by using a tension wheel (14d) in contact with the belt (13) also has the function of inhibiting the bending of the belt (13) during traveling; the rotation center position of the tension pulley (14d) is positioned near the driven side pulley (12), sothat the tension pulley (14d) of the tension adjusting part (14) can be used for properly limiting the belt (13), and even if the advancing direction of the belt (13) is changed due to the reverse rotation of the impeller, the
