Abstract
The present invention discloses a multi-stage fin motor casing. The motor casing is provided with an inner cavity, an axial first-grade fin is arranged at the outer surface of the motor casing, an end cap connection structure is arranged in the first-grade fin, and a plurality of second-stage fins are arranged at the outer surfaces of the first-stage fin and the motor casing. The first-stage fin and the second-stage fin are arranged to increase the heat exchanging area while ensuring the motor casing mechanical property. Compared with the technical scheme of individually increasing the reinforcement, the heat exchanging area is increased, and the heat dissipation efficiency is improved; and a bolt through hole is arranged at the root of the first-stage fin to ensure the connection stability of the end cap, and the raw material usage amount is reduced and the production process is decreased through comparing with other arranged connection devices.
Description
Technical field
The present invention relates to electro-mechanical arts, be specifically related to a kind of multistage fin motor casing.
Background technology
The heat energy that stator in motor and rotor produce is by conduction of heat to shell, and with hot spoke
The mode penetrated is dispersed in the fluids such as sky gas and water, oil.Usual aluminium conduct in prior art
The sheathing material of motor, because aluminum density is little, heat conductivility is excellent, convenient processing and manufacture and one-tenth
This is relatively low.But the mechanical strength of aluminum and rigidity are significantly lower than other metals such as cast irons, in not reaching
The use requirement of the higher motor of the heart.In prior art, the general wall thickness using increase motor casing
Or the method increasing reinforcement improves mechanical strength, but so can reduce the heat dispersion of shell,
Increase the consumption of sheathing material simultaneously, relatively costly.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, it is provided that a kind of multistage fin electricity
Casing, its mechanical performance and rigidity are strong, and radiating efficiency is high.
To achieve these goals, the motor casing of technical scheme has inner chamber, motor
Shell outer surface is provided with along the axial one-level fin of motor casing, and one-level fin is internally provided with end cap
Attachment structure, one-level fin and motor casing outer surface are provided with several two grades of fins；Inner chamber is
Cylinder, the outline of motor casing is cylindrical, at the bottom of the bottom surface of inner chamber and the outline of motor casing
Face is concentric circular；Axially one-level fin is at least three, and one-level fin is equal at motor casing outer surface
Even distribution.
More stable in order to make end cap connect, preferred technical scheme is, end cap attachment structure is for setting
Putting at one-level fin roots along the axial bolt hole of elevator housing, bolt hole is at least three
Individual.
In order to increase effective heat exchange area further, preferred technical scheme is, one-level fin
End be V-arrangement.
In order to improve mechanical performance and the rigidity of motor casing further, preferred technical scheme is,
The thickness of one-level fin is more than the thickness of two grades of fins.
Advantages of the present invention and having the beneficial effects that: by arranging one-level fin and two grades of fins,
While ensureing motor casing mechanical performance, increase heat exchange area, with the simple skill increasing reinforcement
Art scheme is compared, and heat exchange area significantly increases, and improves radiating efficiency；Set at one-level fin roots
Put bolt hole, it is ensured that the stability that end cap connects, compared with separately attachment means is set, reduce
Raw material usage amount, reduces production process.
Accompanying drawing explanation
Fig. 1 is the structural representation of motor casing of the present invention.
In figure: 1, motor casing；2, inner chamber；3, one-level fin；4, two grades of fins；5、
Bolt hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is retouched further
State.Following example are only used for clearly illustrating technical scheme, and can not be with
This limits the scope of the invention.
Seeing Fig. 1, motor casing 1 has inner chamber 2, and motor casing 1 outer surface is provided with axial
One-level fin 3, one-level fin 3 is internally provided with end cap attachment structure, one-level fin 3 and electricity
Casing 1 outer surface is provided with several two grades of fins 4；Inner chamber 2 is cylindrical, motor casing 1
Outline be cylindrical, the bottom surface of inner chamber 2 is concentric circular with the outline bottom surface of motor casing 1；
Axially one-level fin 3 is 8, and one-level fin 3 is uniformly distributed at motor casing 1 outer surface；End
Cover attaching structure is the bolt hole 5 being arranged on one-level fin 3 root vertically, bolt hole
5 is three；The end of one-level fin 3 is V-arrangement；The thickness of one-level fin 3 is more than two grades of fins
The thickness of sheet 4.
The above is only the preferred embodiment of the present invention, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from the technology of the present invention principle, it is also possible to
Making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
