The internal structure of the motor for industrial fans has a component that is rarely mentioned but is indispensable in the rotational motion of the machine - the shaft. A shaft is a cylindrical object that is fitted between the bearing wheels or gears. In special cases, it can also be square or other shapes. Each section can have different diameters. The parts that rotate on the machine are mounted on the shaft.

There are many types of shafts, including crankshafts, straight shafts, flexible shafts, solid shafts, hollow shafts, etc. The use and study of shafts by people began early and is closely related to daily life. In mechanical design, shafts can support rotating parts and transmit motion or torque.

Shafts have many requirements, and in different situations, they need to be designed and manufactured differently, requiring different materials. Under normal circumstances, high-quality carbon steel in steel has higher comprehensive performance. Most shafts are made of high-quality carbon structural steel. If the torque or load is small, general carbon steel can be used for manufacturing occasionally. Conversely, if the torque or load is large, or in special situations, specific alloy steel must be used for production. Finally, the shaft cannot be connected directly to another shaft, so when a connection is required, we need to use a coupling to connect and transmit motion.

The HVIST fan was invented by a joint venture between a US and a Chinese company in 1999. After almost 20 years of development, various industrial fans with different numbers of blades have emerged. Currently, domestically and internationally, industrial fans mainly come in three-blade, four-blade, five-blade, six-blade, and eight-blade configurations. In theory, the more blades a fan has, the greater the airflow. However, since industrial fans are generally larger in size, more blades also mean more weight and increased safety risks. Therefore, it is necessary to strike a good balance between airflow and quality. Currently, industrial fans with five or six blades are most popular on the market. These two types are also the main products promoted abroad and have been market-certified for over a decade. As long as manufacturers strictly require high quality and safety for the blades, they can meet market demand.

With the promotion of nationwide fitness, various communities have built indoor basketball courts of different sizes. However, the large span, high height, and relatively sealed building structure of basketball courts pose great challenges to ventilation and cooling. In recent years, many venue constructors have found that large fans (big ceiling fans) can perfectly solve the ventilation and cooling problems, which are tricky for indoor basketball courts.

Industrial large fans have been imported into China from abroad, and batches of industrial fan manufacturers have been continuously researching, developing, and producing a full range of large industrial fan series products suitable for various environmental improvements in China. High-quality large fans are often built on good materials and unique advanced designs. The fan blades of industrial large fans are made of 5052 aviation aluminum, and unique blade designs can maximize the advantages of large fans and meet the needs of different users. When designing fan blades, industrial fan manufacturers need to follow certain principles.
