Abstract
The utility model discloses a fan used for small and medium sized three-phase asynchronous motors. The fan comprises a shaft sleeve, wherein a wind wheel sleeve is fixedly sleeved on an outboard of the shaft sleeve, one end of the wind wheel sleeve is connected with a tapered plate body, the tapered plate body is shaped as a horn mouth, the horn mouth faces an end socket, and blades (3) are uniformly distributed along circumference at a position which is on an outboard conical surface of the tapered plate body and is near the wind wheel sleeve (2). Compared with the prior art, the fan used for small and medium sized three-phase asynchronous motors is large in blast volume, good in cooling effect, low in noise, energy saving, and simple in structure, when the fan rotates along with the rotation of a rotor of the motor.
Description
Technical field
The utility model relates to a kind of fan, particularly a kind of middle-size and small-size threephase asynchronous fan.
Background technology
At present, middle-size and small-size totally-enclosedly normally have the stator, end cap, fan, fan housing etc. of radiating ribs to constitute by support from the ventilation cooling system of fanning cold type mouse-cage type threephase asynchronous.The axial ventilation pattern is adopted in the cooling of ventilating, and promptly upward arranges to install in shaft of motor (rotor) to turn to benzvalene form fan reversible, that diameter is big, blade radial distributes.By the fan rotating boosting, form air-flow, air is sucked from the fan housing window of motor, flow out by the fan housing outlet, brush, flow, along support and support radiating ribs surface to reach the purpose of cool motors.Existing Y series, Y2 serial motors and the YX3 high-efficiency electric motor of releasing recently and being about to promote all adopt above-mentioned benzvalene form radial fan and axial ventilation layout.Theoretical and the experiment according to electrical engineering is when the linear velocity of fan outer rim reaches 60m/S and when above, its ventilation noise is the motor main noise source, has the shortcoming that noise is big, waste energy.
Summary of the invention
The purpose of this utility model provides a kind of motor air cooling system noise middle-size and small-size threephase asynchronous fan low, energy-conservation, simple in structure.
Middle-size and small-size threephase asynchronous fan of the present utility model, comprise axle sleeve, fixed cover is equipped with the fan blade cover in the outside of axle sleeve, one termination of fan blade cover has the taper plate body, described taper plate body is bell mouth shape, this horn mouth is evenly distributed with blade near fan blade cover place circumference towards the termination on the conical surface of the outside of taper plate body.
Middle-size and small-size threephase asynchronous fan of the present utility model has compared with prior art when rotating with motor rotor that air quantity is big, a good cooling results, low, energy-conservation, the simple advantage of joint knot of noise.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that schematic diagram is looked on a left side shown in Figure 1;
Fig. 3 is the state diagram that fan of the present utility model is installed in the motor rotary shaft end.
Embodiment
As shown in Figure 1, 2: 1 is axle sleeve, and the endoporus of axle sleeve 1 is processed with keyway and is used for and the motor rotary shaft key connecting.
At the outside of axle sleeve 1 fixed cover fan blade cover 2 is housed, can adopts direct casting all-in-one-piece worker add mode.
The rear end of fan blade cover 2 is connected to taper plate body 4, and taper plate body 4 is bell mouth shape, and this horn mouth is towards the termination, and taper plate body 4 is structure as a whole with fan blade cover 2.
Overlap 2 place's circumference near fan blade and be evenly distributed with blade 3 on the conical surface of the outside of taper plate body 4, the quantity of blade 3 is 8, can determine according to the size of the rating of electric machine, and blade 3 is structure as a whole with taper plate body 4 and fan blade cover 2.
As shown in Figure 2: 5 is the termination of motor rotary shaft, and this fan is sleeved on the termination of rotating shaft 5, by snap ring 6 axial restraints, radially fixing by key 7.
Claims (1)
1. one kind middle-size and small-size threephase asynchronous fan, comprise axle sleeve (1), it is characterized in that: the outside fixed cover at axle sleeve (1) is equipped with fan blade cover (2), one termination of fan blade cover (2) has taper plate body (4), described taper plate body (4) is bell mouth shape, this horn mouth is located circumference near fan blade cover (2) and is evenly distributed with blade (3) towards the termination on the outside conical surface of taper plate body (4).
