High-efficiency motor backward-tilting fan blade and manufacturing method thereof

Abstract

The invention discloses a high-efficiency motor backward-tilting fan blade and a manufacturing method thereof, and belongs to the technical field of high-efficiency motor backward-tilting fan blades and manufacturing methods thereof. The high-efficiency motor backward-tilting fan blade comprises two fan discs, wherein opposite surfaces of the two fan discs are fixedly connected through six fixingrods; the same gear is arranged on the opposite surfaces of the two fan discs; the gear is meshed with six gears; and a toothed plate is slidably connected in two sliding grooves. According to the high-efficiency motor backward-tilting fan blade and the manufacturing method thereof, the fan blade is processed and manufactured by adopting a numerical control processing mode, the problems caused bypouring manufacturing and extrusion forming manufacturing can be effectively avoided through the numerical control processing mode, the fan blade can be directly used for plastic spraying after numerical control processing forming, subsequent reprocessing is not needed, the rigid strength of a steel plate is prevented from being directly influenced by rigid extrusion, so that the fan blade is notprone to rebound, and the service life of the fan blade is guaranteed while the manufacturing precision of the fan blade is improved.

Description

technical field [0001] The invention belongs to the technical field of a high-efficiency motor backward-inclined fan blade and a manufacturing method thereof, in particular to a high-efficiency motor backward-inclining fan blade and a manufacturing method thereof. Background technique [0002] High-efficiency motors refer to motors with higher efficiency than general-purpose standard motors. At present, most high-efficiency motors are optimized from the electromagnetic aspects of the motor, and less involved in improving the structure, shape and manufacturing methods of the motor fan. The existing high-efficiency Most of the fan blades with motor backward tilt and their manufacturing methods are integrated structures. Since the fan blades are fixed on the fan disk, they cannot be disassembled. When one or several blades are damaged, the fan assembly needs to be disassembled. Then the fan disk and the blades are removed and replaced, which increases the cost of maintenance wh...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency motor backward tilting fan blade and its manufacturing method, which solves the problem that the fan blade cannot be disassembled because the fan blade is fixed on the fan disk, and when a single or several blades appear When it is damaged, it is necessary to disassemble the fan assembly and then remove and replace the fan disk and blades, which brings a large burden to the staff and improves the maintenance. Pouring and extrusion molding directly affect the manufacturing accuracy of the fan blades and their performance. Lifetime cost issues
