Abstract
The utility model discloses a motor fan with low noise and low vibration, which comprises blades, wherein the blades are fixed on a fan shaft sleeve through screw bolts. The utility model is characterized in that an included angle of 55 degrees is formed between the upper side of the front end of the blade and the perpendicular line of the shaft line of a motor; an included angle of 35 degrees is formed between the lower side of the back end of the blade and the perpendicular line of the shaft line of the motor; and seven blades are uniformly distributed. Compared with the prior art, the utility model has the advantages that through the unique structure design of the fan blade, the noise and the vibration of the motor are obviously reduced, the air friction is reduced, and the motor efficiency is improved.
Description
Technical field:
The utility model relates to the low vibrating motor fan of a kind of low noise.
Background technique:
Electrical motor fan of the prior art causes noise and vibration all bigger owing to adopt two-way centrifugal benzvalene form fan structure and strengthen the poly-third ethene material.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of low noise to hang down the vibrating motor fan.
The technical scheme in the invention for solving the above technical problem is: this low noise hangs down the vibrating motor fan, comprise blade, blade pass is crossed and is bolted to fan shaft and puts, it is characterized in that blade front end top becomes 55 ° of angles with the electrical axis vertical line, blade rear end bottom becomes 35 ° of angles with the electrical axis vertical line.
Blade described in the utility model is equally distributed 7.
The utility model compared with prior art has following advantage and effect: by the fan blade structural design of uniqueness, the noise of motor and vibration are obviously descended, reduce with the friction of air, improved the efficient of motor.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the axial schematic representation of the utility model embodiment blade.
Embodiment:
Referring to Fig. 1, Fig. 2, the utility model embodiment comprises blade 1, and blade 1 is by being bolted on the fan axle sleeve 2, and blade 1 front end top 11 becomes 55 ° of angles with the electrical axis vertical line, and blade 1 rear end following 12 becomes 35 ° of angles with the electrical axis vertical line.
Present embodiment blade 1 is equally distributed 7.
The utility model makes the noise of motor and vibration obviously descend by changing inclination angle, gateway and the external diameter and the width dimensions shape of fan blade 1, reduces with the friction of air, has improved the efficient of motor.
Claims (2)
