ABSTRACT:
A cooling fan is provided on at least one of the drive pulley and the driven pulley on which the drive belt is wound. A substantially closed casing in which the pulleys and the belt are accommodated has its interior partitioned in two chambers. With rotation of the fan, the air inside the casing is circulated within the casing where one of the chambers acts as a going passage and the other as a return passage, respectively, to thereby cool the pulleys and the belt. The two chambers are communicated with each other by communication means which are arranged at the pulleys and adapted to allow smooth movement of the air through the pulleys. Further provided are means for enhancing the efficiency of cooling the driven pulley by the circulating air and means for radiating heat generated within the casing through the casing walls.
