The middle part of axis is equipped with radiator fan by tail end, this is conventional design, for dredging the heat of stator rotor to end cap.
Lid 1 uses low-temperature resistant and shock resistant ductile cast iron material, and by the inoculated technology of design science, casting technique,
Solve the problems, such as interiors of products shrinkage porosite, make product in -40 DEG C--60 DEG C ballistic work >=12J of low temperature, tensile strength >=
400Mpa, product comprehensive mechanical property reach domestically leading level；By designing reasonable processing technology, product processing essence ensure that
Degree reaches IT6 grades, meets the assembly demand of high-speed rail.
Such as Fig. 2, end cap further includes flow deflector 2 and spring leaf 3；
Such as Fig. 5, the flow deflector 2 is cyclic annular taper, is radially successively arranged circle from inside to outside on the flow deflector 2
Several interior deflector hole 2-1 of week distribution and several outer deflector hole 2-2 of circle distribution；The interior deflector hole 2-1 and outer deflector hole
The water conservancy diversion direction of 2-2 be obliquely installed relative to 2 surface normal direction of flow deflector, and the two inclined direction on the contrary, to
The contrary revolution air-flow of twice is formed in region between flow deflector 2 and end cap bottom plate, makes Temperature Distribution at end cap more
Add uniformly.
The spring leaf 3 is also annular；The centre bore of flow deflector 2 and spring leaf 3 is passed through for motor shaft.
Such as Fig. 2, the card slot of annular is offered on the wall, the outer edge of the flow deflector 2 is installed in the card slot；
The flow deflector 2, spring leaf 3 and the bearing hole are coaxially disposed, and 3 one end of spring leaf is in contact with the top surface boss 1-2, the other end
It is in contact with the path end face of flow deflector 2.
Further, it in order to facilitate the installation of flow deflector 2, such as Fig. 5, is also provided on the flow deflector 2 and is arranged along bus
The notch 2-3 of perforation facilitate installation with certain deformation space.
In order to accelerate the heat of air-flow to exchange, it is different that adjacent deflector hole tilt angle can also be set: in described
Deflector hole 2-1 is along the circumferential direction divided into M group, and adjacent interior deflector hole 2-1 is relative to 2 surface method of flow deflector in such as 10 groups, every group
Tilt angle to direction is unequal, preferably selects between 15 to 25 degree.10 groups of deflector hole circulation circumference settings, each deflector hole
Angle be along the circumferential direction in circular wave.
Similarly, the outer deflector hole 2-2 be along the circumferential direction divided into outer deflector hole 2-2 adjacent in 10 groups, every group relative to
The tilt angle in 2 surface normal direction of flow deflector is unequal.
As above design, the air-flow that adjacent deflector hole can be made to blow out collide with each other, accelerated heat exchange.
Such as Fig. 2, the annular region on the bottom plate between boss 1-2 and the wall is also provided with several circumference point
The heat release hole 1-1 of cloth；
End cap further includes seal assembly 4, and in the present embodiment, seal assembly 4 is located at the lower section of flow deflector 2.
Such as Fig. 3, annular groove is offered on the wall medial surface, the seal assembly 4 includes copper ring 4-1, falope ring 4-
2, rubber ring 4-3 and several groups one-to-one copper sheet 4-4 and diaphragm seal 4-5 flexible.
The copper ring 4-1 outer edge is installed in annular groove, and alcohol, the silicon are filled in the inner cavity the falope ring 4-2
The cross sectional shape of rubber ring 4-2 is the V-arrangement of outward opening side, the inward flange bottom of the top surface the falope ring 4-2 and the copper ring 4-1
It is connected by bonding method, the rubber ring 4-3 cross sectional shape is the V-arrangement of outward opening side, is sleeved on the outer of falope ring 4-2
On side, the two shape matches, and is connected by bonding method.
The diaphragm seal 4-5 is circumference, and cross sectional shape is horizontally disposed U-shaped and opening direction towards in end cap
The heart is connected, the other side with each side corresponding copper sheet 4-4 diaphragm seal 4-5 with the underrun bonding method of falope ring 4-2
It is connected at the top of diaphragm seal 4-5 by bonding method；The bottom of the diaphragm seal 4-5 is covered on the heat release hole 1-1.
It is well known that alcohol has the characteristic of expanded by heating.When temperature is higher, alcohol expands, falope ring 4-2 and copper ring
Larger deformation cannot occur for two sides of 4-1, copper sheet 4-4 fitting, drive rubber ring 4-3 side deformation, rubber ring 4-3 is supportted
It opens, falope ring 4-2 inner section levels off to triangle, thus change angle of the copper sheet 4-4 relative to copper ring 4-1, such as Fig. 3, then
Diaphragm seal 4-5 is rotated counterclockwise, heat release hole 1-1 is opened, improves heat dissipation effect when high temperature；When the temperature is low, silicon
Rubber ring 4-2 restores under the action of rubber ring 4-3 to V-arrangement, and each diaphragm seal 4-5 is rotated backward, and gradually covers heat release hole 1-1, subtracts
Small heat dissipation area, and dust is avoided to enter.
The purpose of diaphragm seal 4-5 split settings is that on the one hand preventing from being wholely set causes damping due to rotation excessive, on the other hand
The higher regional seal piece 4-5 open angle of temperature can be made bigger, play the role of equilibrium temperature profile.
Further, such as Fig. 4, the bottom of the diaphragm seal 4-5 offers several radiating grooves, the radiating groove and the sealing
The heat release hole 1-1 interlaced arrangement that piece 4-5 is covered, so that the two forms the knot of similar labyrinth seal when diaphragm seal 4-5 is opened
Structure can also play the effect of blocks dust impurity while high temperature heat dissipation.
