What is a fan shaft?

The term fan shaft has two meanings. The most common refers to the rotating spindle on which the fan blade is mounted. The blade is usually mounted at one end of the fan and the other end is connected to the engine, which is often electrically driven. The term is also used to indicate the type of ventilation shaft located in industrial environments, especially mining. The fan shaft differs from passive ventilation in that the fan is mounted in the shaft to actively move the air.

Most electric motors used to power fans have a fan shaft, which is an integral part of the engine itself and to which the fan blade is mounted, without any other parts or mechanisms. Although there are several modifications of this basic design, all fans work on the basic principle of the blade rotating around the central axis. The blades, regardless of the fan configuration, are almost always mounted radially around the fan.

axThe ialian fans moves in the direction parallel to the fan shaft, while the crossing fan moves through the air perpendicular to the shaft and usually has a vent mechanism of venting or bonnet to direct the flow. The centrifugal fan also moves through the air perpendicular to the fan shaft, but in the reception configuration differs from the CrossFlow fan. The cross -flow fan takes the air along the axis perpendicular to the fan, while the centrifugal fan takes the air along its axis, usually at one end.

In the industrial setting, the fan shaft is a type of ventilation shaft used to maintain air quality in a closed space such as mine or other underground installation. In the shaft, the fan is mounted to increase the air flow and also move the flow in a certain direction. Most fans of this type are axial fans and some of them can be extremely large. Drive drives of these types of fan may vary and may be electric, internal combustion orHydraulic. The NSFER tranetpower may also differ, and these fans can be driven by belts, gears or even assembly of the chain and chain wheel.
