This creation relates to an industrial fan transmission structure improvement, especially when the pressure generated by the industrial fan is distributed to reduce the pressure on the support frame group, thereby preventing damage or deformation of the support frame group, thereby enhancing The industrial fan has a solid overall structure.

According to Taiwan, Taiwan is located in the subtropical zone and surrounded by the sea. Apart from the winter season, most of the other three seasons are hot and humid. In the industrialization, the greenhouse effect is becoming more and more serious. The temperature rises in summer every year, and the ventilation effect in the general plant is good, which not only affects the worker's work efficiency, health, and even some temperature-sensitive mechanical equipment or products. The molding also has a great correlation. If the air convection is not good for a long time, it will accumulate odor or harmful gas. Therefore, in order to avoid the above situation caused by poor ventilation, the manufacturer usually installs an industrial fan in the factory. At present, the commonly used industrial fan system uses negative pressure to cause air convection. Even if a motor fan is used to pump the indoor air outward, the indoor atmospheric pressure is lower than the outdoor atmospheric pressure, whereby the outdoor air will naturally The ground flows into the room to achieve the effect of convection.

At present, a common industrial fan structure (as shown in FIG. 6) is mainly provided with at least one bracket 70 on the rear side of the one-side fan base body 7, and a circular shape is formed on the front side of the fan seat body 7.
