Abstract

PURPOSE: To reduce the load at starting an operation, by employing a variable diameter pulley change gear and a speed change control pilot motor mechanism comprising a blower apparatus of the cooling tower to stop it at a maximum change gear ratio.
CONSTITUTION: A belt transmission apparatus A includes stationary and slidable pulleys 6a, 6b on an input rotating shaft 1 that are connected by a belt 4 with stationary and slidable pulleys 7a, 7b provided on an end of an intermediate shaft 2, the other end of which is provided with a small diameter pulley 9 on which is put a V-belt 5 that in turn engages with a large diameter pulley 8 on a blower fan driving shaft 3. a centrifugal blower 30 is provided over the pulley 7, and to a spring part of the pulley 7 are provided an impeller 31, and a cover 32. The driving side pulley apparatus 6 is provided with an operation screw bar 35, and a sprocket 36 installed on the tip of the bar 35 is controlled by a pilot motor controller 40, so that the change gear ratio is varied according to the cooling water temperature. Further, when it is stopped, it is made to be forcibly stopped in the state of a maximum reduction gear ratio so that it may be started from a light load state when it is required to start.
