Advantages: The fan speed range is large, the flow is closer to application needs, the motor installation position is more flexible, the belt pulley disassembly is more convenient, and the space occupied is smaller.
Disadvantages: The mechanical efficiency is relatively low. Belt transmission requires tensioning force, adding extra lateral force to the fan shaft end. There are more easily damaged parts and high frequency of maintenance and renewal.
Main application: Suitable for medium-sized and above fans with a large range of performance variations.">
Structural type: Cantilevered, belt drive structure, the belt pulley is installed on the outside of two supporting bearings, and the impeller is cantilever-mounted on the other end of the shaft.
