What are the three kinds of transmission of axial flow fan?
The driving mode of axial flow fan is commonly used in three forms: motor direct connection, triangle belt driving and coupling linkage.
Type A: direct motor connection. The fan impeller is directly mounted on the motor shaft. Generally, small numbers are used.
Type B: wheel drive. The pulley is mounted between two bearings.
Type C: wheel drive. The pulley cantilever is installed at one end of the main shaft, and the impeller cantilever is installed at the other end of the main shaft.
Type D: coupling linkage. Impeller cantilever is installed on the main shaft (air duct structure).
Type E: coupling linkage. The impeller cantilever is mounted on the main shaft (no air duct structure).
