Description
Technical field
The utility model belongs to field of motor manufacturing, relates to a kind of motor, especially a kind of DSDZ type low noise tunnel axial-flow fan motor.
Background technology
The 650kg axial thrust of generation when the motor that is used for the tunnel axial flow blower requires motor bearings and rotating shaft need satisfy deadweight of 400kg impeller and axial flow blower operation; Can be under the fire condition 200 degrees centigrade of operations one hour; The wind path of motor and aerofoil fan is consistent, and motor volume should reduce to greatest extent according to apparatus casing.
And present most of high pressure cage rotor motor is the F class F insulation, and bearing does not require bearing axial pushing force, when moving under airtight, hot conditions, has brought potential safety hazard for the operation of motor reliability, and efficient and power factor are lower.Therefore when this kind motor applications during, do not satisfy user's demand in the tunnel axial flow blower.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of low noise tunnel axial-flow fan motor is provided, and this kind motor is effectively improved the heat dispersion of motor by adding the cooling structure of motor.
The purpose of this utility model solves by the following technical programs:
This low noise tunnel axial-flow fan motor is equipped with aerofoil fan and fan housing at the non-shaft stretching end of described motor, and described aerofoil fan is consistent with the tunnel axial flow blower rotation direction that is installed on motor shaft extension end; Be evenly equipped with cooling water pipe around the stator of described motor.
The cramp structure is adopted in the stator core of above-mentioned motor.
Be provided with sealing ring between the bearing cap of above-mentioned motor and the machine shaft, described sealing ring is made up of outer shroud and internal buckle ring; The inner ring of described outer shroud is connected with a tubular structure to the inside, and the inboard port of export of this tubular structure turns up, inside perk one angle in the outer ring of this outer shroud; The periphery of described internal buckle ring is along being thinner than internal buckle ring ring body thickness and its periphery along one angle of perk to the inside; Described internal buckle ring is enclosed within on the tubular structure of described outer shroud.
Tunnel of the present utility model axial-flow fan motor is by adding aerofoil fan and fan housing at non-shaft stretching end, and cooling water pipe is distributed on around the stator, thereby effectively improved the heat dispersion of whole motor, under the prerequisite that satisfies motor installation, environment for use, the operation of motor performance and reliability is greatly improved.

Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
The utility model is improved on the basis of existing motor, therefore, as shown in Figure 1, this kind low noise of the present utility model tunnel axial-flow fan motor has comprised on the existing motor as support 3, stator 4, rotor 5, machine shaft 11, bearing assembling 1, wind deflector 6, end cap 2, bearing 12, bearing cap 10 parts such as grade, improvements of the present utility model are: the non-shaft stretching end at motor adds aerofoil fan 7 and fan housing 8, and require aerofoil fan 7 consistent with the tunnel axial flow blower rotation direction that is installed on motor shaft extension end, adopt the aerofoil fan consistent that motor is cooled off, solved wind path and reliability operation problem with the axial flow blower wind path.In addition, the utility model is uniform cooling water pipe 15 around the stator 4 of motor also, as shown in the figure, the two ends of cooling water pipe 15 are fixed on the support 3, this around the stringing structure decrease wind abrasion, improved ventilation and heat, improved electric machine temperature rise, improved efficient and can effectively reduce motor volume.In the preferred embodiment of the present utility model in addition, the stator 4 cramp structures that adopt unshakable in one's determination of motor.
Consider that motor bears the characteristics of axial force, motor of the present utility model also needs to improve bearing intensity and relate to by bearing life and load ground are adjusted.In addition on the bearing seal mode, the utility model adopts new structure: as shown in Figure 2, be provided with sealing ring 9 between the bearing cap 10 of motor and machine shaft 11, sealing ring 9 is made up of outer shroud 13 and internal buckle ring 14; The inner ring of outer shroud 13 is connected with a tubular structure to the inside, and the inboard port of export of this tubular structure turns up, inside perk one angle in the outer ring of this outer shroud 13; The periphery of internal buckle ring 14 is along being thinner than internal buckle ring ring body thickness and its periphery along one angle of perk to the inside; Internal buckle ring 14 is enclosed within on the tubular structure of described outer shroud 13.Sealing ring 9 of the present utility model adopts H level mica insulation.The structure of sealing circle 9 can prevent effectively that the lubricating oil in the bearing cap 10 from spilling, and also can play the good insulation performance effect.
In sum, uniform cooling water pipe around the stator 4 of the present utility model, non-shaft stretching end adopt aerofoil fan to carry out exhausting, have solved the motor ventilation heat dissipation problem, and have made it consistent with tunnel blower fan wind path; The cramp structure is adopted in stator core, and when Electromagnetic Design, it is close to consider that unit stator iron core pressing and motor performance have reduced the yoke portion magnetic of stator; Bear the characteristics of axial force at motor,, can further improve bearing arrangement, dwindle motor weight, volume to greatest extent by bearing life and load ground are adjusted.
The utility model has solved common YKK electric machine temperature rise height, inefficient problem, has made the motor ventilation heat radiation that better improvement arranged, and noise is lower.Under installation environment, position qualifications, can make motor compact more.Because electric machine stand and cooler one can be raised labour productivity greatly.
