Gearing-down device and method for industrial fan

Abstract

The invention discloses a gearing-down device and method for an industrial fan. The device comprises an input shaft, a planet gear assembly, a drive disc and an output shaft. One end of the input shaft is externally connected with a motor, the other end of the input shaft is connected with the drive disc through the planet gear assembly, a spherical connecting surface is arranged at one end of the output shaft, and the output shaft is connected with the drive disc through the spherical connecting surface. The method includes the steps that after the motor externally connected with the gearing-down device outputs power to the input shaft, speed reduction is carried out through the planet gear assembly, the planet gear assembly drives the drive disc to rotate, the output shaft is connected with the drive disc through the spherical connecting surface, and the output shaft is driven by the drive disc to output power. A traditional single-shaft output drive structure is changed into a multi-segment type output drive structure, the planet gear assembly and the drive disc are used for drive, radial torsion generated due to the fact that a drive shaft is too long is reduced, the balance of drive output is improved, the power output shaft is kept vertical to natural rotating surfaces of fan blades all the time, and therefore the energy consumption of a fan is reduced.

Description

technical field [0001] The invention relates to the technical field of industrial fans, in particular to a reduction transmission device and method for industrial fans. 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] However, due to the large diameter of the blades of this fan, the large area of ​​rotation and agitation, and the long cantilever of the blades, it i...

AI Technical Summary

Problems solved by technology

[0003] However, due to the large diameter of the blades of this type of fan, the large area of ​​rotation and agitation, and the long cantilever of the blades, it is greatly affected by the ambient air flow. When the fan is working, the working surface formed by the blade rotation is often not between the output shaft of the reduction mechanism. In the vertical state, after the deceleration device and the power mechanism are installed, the power output shaft is difficult to be in a vertical state with the natural rotating surface of the blade, which is likely to cause radial torque on the output shaft, which increases the energy consumption loss of the power device and the power mechanism. Mechanical wear reduces the service life of the fan and increases the maintenance workload. The maintenance cost is high. Therefore, if the power output shaft can adapt to the vertical blade rotation surface, the above problems can be effectively solved, thereby improving the use of the fan. Long life, reduce energy loss and maintenance cost
