Abstract
Locomotive of the present utility model is with high-power lightweight ventilation blower, it is made up of motor, impeller, guide shell and Blower Housing, motor field frame, impeller, Blower Housing are aluminum alloy material, Blower Housing is upper and lower two-part split-type structural, upper body is formed by aluminium alloy plate is welded, lower case is formed by aluminium alloy casting, and its structure is to arrange stator between inside and outside cylinder, and upper and lower part housing passes through bolt and sealing member connects.The material thickness of the upper body being not subject to compared with big load can be down to minimum, it is to avoid the deformation that lower case leads to because of welding, thus on the premise of ensureing mechanical performance index, realizing loss of weight to greatest extent.
Description
Technical field
This utility model is related to a kind of locomotive with high-power lightweight ventilation blower, belongs to locomotive manufacturing technical field.
Background technology
Modern locomotive develops to high-speed overload direction, and the weight mitigating in-vehicle device is the emphasis designing all the time.
In the car in equipment, ventilation blower accounts for larger ratio in whole locomotive weight.For mitigating the weight of ventilation blower, existing skill as far as possible
Art takes thousand and one way.One effective method is it is simply that changing the material of some parts on blower fan, for example electric by blower fan
The casing of machine is replaced by cast aluminium material by cast iron quality, and Blower Housing is replaced by aluminum alloy material by carbon steel material.But, right
In some vertically-mounted blower fans, Blower Housing needs to bear certain load, while being replaced by aluminum alloy materials, also must
The thickness of material must be increased meeting the requirement in intensity, this offset more conversion materials and subtracting of bringing to a great extent on the contrary
Weight effect.
Utility model content
The purpose of this utility model is exactly the deficiency overcoming above-mentioned prior art, provides a kind of locomotive high-power lightweight
Ventilation blower.
The purpose of this utility model is realized in：A kind of locomotive with high-power lightweight ventilation blower, by motor, leaf
Wheel, guide shell and Blower Housing are constituted, and motor field frame, impeller, Blower Housing are aluminum alloy material it is characterised in that described
Blower Housing is upper and lower two-part split-type structural, and upper body is formed by aluminium alloy plate is welded, and lower case is closed by aluminum
Gold casting forms, and its structure is to arrange stator between inside and outside cylinder, and upper and lower part housing passes through bolt and sealing member connects.
The technical solution of the utility model, Blower Housing adopts upper and lower split-type structural, according to respective present position not
With bearing capacity and intensity requirement, it is respectively adopted aluminium alloy plate welding structure and aluminium alloy cast structure, one is can be larger by being not subject to
The material thickness of the upper body of load is down to minimum, and two are that of avoiding the deformation that lower case leads to because of welding, thus protecting
On the premise of card mechanical performance index, realize loss of weight to greatest extent, the further loss of weight 20% than former single welding structure.

Specific embodiment
Purpose, technical scheme and advantage for making this utility model embodiment are clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described it is clear that being retouched to the technical scheme in this utility model embodiment
The embodiment stated is a part of embodiment of this utility model, rather than whole embodiments.Based on the enforcement in this utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, broadly fall into
The scope of this utility model protection.
Referring to accompanying drawing, the locomotive of the present embodiment with high-power lightweight ventilation blower, by motor 12, impeller 4, guide shell 1
Constitute with Blower Housing, motor 12 housing, impeller 4, Blower Housing are aluminum alloy material.Motor 12 casing adopts cast aluminium
Material, end cap adopts cast-aluminum end cover, and carbon steel steel bushing is inlayed in bearing with end cover room, is evenly arranged four installations outside motor 12 casing
Ear, motor is cooled to the structure of its fanning wind cooling, and it is cold that motor cooling relies on draught fan impeller by-passing part cooling air that motor is carried out
But, motor need not carry cooling fan, and this structure had both farthest alleviated the weight of motor, reduced the length of motor again
Degree is moreover it is possible to ensure that bearing chamber will cause bearing outer ring to separate with bearing chamber because of expanded by heating.Impeller 4 adopts cast aluminium leaf
Wheel.Blower Housing is upper and lower two-part split-type structural.Upper body 3 is formed by aluminium alloy plate is welded, and guide shell 1 is adopted
Rolled with carbon steel steel plate and form；Lower case is formed by aluminium alloy centrifugal casting, and its structure is to arrange between inside and outside cylinder 10,8 to lead
Leaf 9, inner core 10 is evenly arranged four motor mount 11.Blower fan upper and lower part housing is fastened by bolts part 6 and sealing gasket 7
Connect.Motor 12 and leaf 4 wheel pass through to be connected with the mounting seat 11 of blower fan lower case after the axis of cone is bonded.Guide shell 1 and wind
Machine upper body 3 is connected by securing member 2.Motor mount on motor 12 mounting ear of itself and blower fan lower case
11 are bolted.
Finally it should be noted that：Above example only in order to the technical solution of the utility model to be described, is not intended to limit；
Although being described in detail to this utility model with reference to the foregoing embodiments, it will be understood by those within the art that：
It still can be modified to the technical scheme described in foregoing embodiments, or wherein some technical characteristics are carried out etc.
With replacement；And these modifications or replacement, do not make the essence of appropriate technical solution depart from this utility model each embodiment technology
The spirit and scope of scheme.
