Description
Technical field
The utility model belongs to technical field of motors, is specifically related to a kind of external fan silencing end cover and disappears with external fan
The motor of sound end shield.
Background technology
At present, conventional external fan end shield is as shown in figure 3, dragging external fan rotates and produces air quantity during motor operation, air quantity
Fan end shield enters cooler of electric motor out, carries out heat exchange by cooler and motor internal, takes away motor internal heat,
So as to reduce motor temperature rise.Conventional end shield has the disadvantage that:Air inlet is located at the noise of motor measurement point of end shield rear end, and
It is high without noise countermeasure, ventilation noise.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of simple in construction, and cost is low and can reduce outside motor
The silencing end cover of ventilation fan noise, motor is set to reach the external fan silencing end cover of environmentally friendly low noise requirement and disappear with external fan
The motor of sound end shield.
The technical solution adopted in the utility model is：A kind of external fan silencing end cover, including end shield, cone-shaped hood and hood,
Described cone-shaped hood and hood are arranged on the air inlet of end shield, and cone-shaped hood is located in hood；It is provided with cone-shaped hood and hood
Deadener；Hood is provided with air inlet.
In above-mentioned external fan silencing end cover, described end shield is double-layer steel plate structure.
A kind of motor with above-mentioned external fan silencing end cover, including external fan silencing end cover, described external fan are eliminated the noise
The end shield of end shield is arranged on non-shaft stretching end on motor, on the outside of external fan.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, and cost is low；This reality
Double-layer steel plate structure is designed to new end shield, end shield air inlet adds the cone-shaped hood and hood for noise elimination, and
Air inlet is arranged on the side of hood, and wind path is played a part of insulating against sound and eliminated the noise, has reached the effect for reducing noise of motor.
Brief description of the drawings
Fig. 1 is the front view of external fan silencing end cover of the present utility model.
Fig. 2 is the left view of external fan silencing end cover of the present utility model.
Fig. 3 is the structural representation of existing external fan end shield.
Embodiment
The utility model is further described below in conjunction with accompanying drawing.
As shown in Figure 1, 2, external fan silencing end cover of the present utility model includes end shield 1, cone-shaped hood 3, hood 4；Described
Cone-shaped hood 3 and hood 4 are arranged on the air inlet of end shield 1, and the cover of taper 3 is in hood 4.It is provided with cone-shaped hood 3 and hood 4
Deadener；Hood 4 is provided with air inlet 5.
A kind of motor with external fan silencing end cover, the end shield 1 of described external fan silencing end cover are arranged on motor
Non-shaft stretching end, positioned at the outside of external fan 2.During motor operation, machine shaft dragging external fan 2 rotate and produce air quantity, wind from
The air inlet 5 being arranged on the side of hood 4 enters, and cooler of electric motor is entered after end shield 1.
The utility model is simple in construction, and cost is low.The end shield 1 of external fan for electric machine silencing end cover of the present utility model designs
Into double-layer steel plate structure, the air inlet of end shield 1 adds cone-shaped hood 3 and hood 4 for noise elimination, and air inlet 5 is set
In the side of hood 4, wind path is played a part of insulating against sound and eliminated the noise, has reached the effect for reducing noise of motor.
