Industrial fan and blade rotation method thereof

Abstract

The invention discloses an industrial fan and a blade rotation method thereof. The industrial fan comprises a motor driving mechanism, a blade rotating mechanism and a plurality of blades. The blade rotating mechanism comprises an input shaft gear, a planetary gear set, an internal gear and a rotating disk, the output end of the motor driving mechanism is connected with the input shaft gear, the input shaft gear is arranged in the center of the planetary gear set, planetary gears in the planetary gear set are meshed with the input shaft gear, the internal gear is arranged on the periphery of the planetary gear set and meshed with the planetary gear set, and the internal gear is fixed on the rotating disk. The blades are evenly distributed on the periphery of the rotating disk. The blade rotation method of the industrial fan comprises the steps that the motor driving mechanism outputs power, transfers the power to the input shaft gear and then drives the planetary gears to rotate, and the planetary gear set drives the internal gear to rotate and then drives the blades to rotate through the rotating disk. By using cooperation of the input shaft gear, the planetary gear set and the like, on one hand, an effect equal to a reduction gearbox is played, and on the other hand, a rotation driving device for the blades is formed, and the structure of the fan is simplified.

Description

technical field [0001] The invention relates to the technical field of industrial fans, in particular to an industrial fan and a blade rotation method thereof. Background technique [0002] Industrial fans refer to fans used in industrial workshops for cooling, cooling, and improving the working environment of workshop staff. In the current workshop environment, most industrial fans are hoisted on the upper part of the workshop, and the diameter of the fan blades is generally 4 to 8 meters. The average air supply area of ​​one fan is 500-1000 square meters. Using this kind of fan to replace the single fan in the workshop has obvious cooling effect, and the relative power saving effect is obvious, and the human body feels better. Therefore, it has been widely used in recent years. Factory welcome and adoption. [0003] There are two main structural forms used by existing industrial fans: one is that the main engine is connected with the reduction box, and then the output sha...

Problems solved by technology

However, in practical applications, the structures of these two types of industrial fans are relatively complex, and the manufacturing and maintenance costs are relatively high, which is not conducive to the control of production costs.
