Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the present invention can be wanted by right
The multitude of different ways limited and cover is asked to implement.
Refer to Fig. 1, the invention provides a kind of rotor baffle plate, its for the cast aluminium of rotor and
In the course of processing, it is particularly useful in cast aluminium and the course of processing of high power induction motor rotor.
It is as it is shown in figure 1, this rotor baffle plate and motor rotor punching sheet mating shapes, the most rounded,
Including plate body.In order to coordinate with the dummy shaft used by cast aluminium, the plate body of the present invention is formed with central through hole 1,
It is for coordinating with dummy shaft during cast aluminium.Additionally, be also formed with multiple gear being arranged radially on plate body
Board slot mouth 2, these baffle plate notches 2 are corresponding to the notch of motor rotor punching sheet to be processed and around described center
Through hole 1 is circumferentially disposed, can ensure that and do not hide described motor rotor punching sheet when assembling with motor rotor punching sheet
Notch.
During use, the rotor baffle plate in the present invention is arranged on the end face of rotor, so, can
Utilize rotor baffle plate to bear certain strain, thus ensure rotor its end in machining process
The punching in face does not rebound and warps, and also can ensure when moving back cast-aluminum dummy shaft to make motor rotor inner hole be difficult to the change that is stretched
Shape.Preferably, the optional material system bigger than motor rotor punching sheet intensity of the rotor baffle plate in the present invention
Become, and effectively tightened with motor rotor punching sheet by cast aluminium and coordinate, such as, rotor two ends can be passed through
The cast aluminium end ring in face compresses the rotor baffle plate in the present invention, so that it is combined closely with motor rotor punching sheet,
As shown in Figure 2.
Visible, owing to have employed technique scheme, the present invention can prevent the end punching deformation of rotor,
Thus reduce secondary precompressed manufacturing procedure, cost-effective, moreover it is possible to ensure the end face squareness peace of rotor
Row degree, is substantially reduced the jitter values of rotor, the dynamic balancing of lifting motor rotor, also makes itself and compressor
Assembling is easier to realize, and makes the running stability of compressor complete machine be improved, and promotes complete machine service behaviour.
In order to bear bigger power, improving anti-deformation effect, in the present invention, the thickness of plate body is the most described
The thickness of motor rotor punching sheet, and the width of baffle plate notch 2 is wider than the width of notch of described motor rotor punching sheet
Degree, is beneficial to following process.As such, it is possible to be readily apparent that to prevent punching endoporus from sending out in cast aluminium and processing
Raw deformation, is to a certain degree serving fastening compression to punching, the most more can bear certain strain simultaneously
Ensure that endoporus does not deforms upon.
Preferably, the quantity of described baffle plate notch 2 is equal to the quantity of the notch of described motor rotor punching sheet, with
The outside making each magnetic pole of the stator of motor rotor punching sheet is all positioned by the rotor baffle plate in the present invention.
Preferably, the edge of described central through hole 1 is formed with keyway 3, and central through hole 1 and punching endoporus is big
Little correspondence.So, do not interfere with the performance of motor rotor punching sheet after assembling, do not interfere with cast aluminium effect yet.
Preferably, the edge of described keyway 3 is formed with mark groove 4.So, both can ensure that rotor kept off
The positive and negative of plate and punching is distinguished, and this mark groove plays good fixation and recognition effect during cast aluminium,
Avoid the inaccurate cast aluminium skew caused of rotor baffle plate and rotor punching para-position, the quality such as cast aluminium broken strip
Abnormal.Visible, differentiation positive and negative can be positioned by keyway and mark groove and assemble, and play fixation.
In one embodiment, the cross section of keyway 3 is the most u-shaped, and it includes the first side being sequentially connected with
Limit, base and second side, and mark groove 4 is positioned at the side at place, base of U-shaped, and described mark
Groove 4 is different from the distance of two sides.It is highly preferred that described mark groove 4 and the distance of described first side
Distance more than described mark groove 4 with described second side.
Present invention also offers a kind of rotor, including motor rotor punching sheet, also include such as front arbitrary enforcement
Rotor baffle plate described in example, wherein, described rotor baffle plate and described motor rotor punching plate shape phase
Coupling.
Preferably, described rotor baffle plate is arranged at the rotor of at least one end of described rotor
Outside punching, and compressed by the cast aluminium end ring of described rotor.
Preferably, outside the motor rotor punching sheet at the both ends of described rotor, it is respectively provided with described motor to turn
Sub-baffle plate, as shown in Figure 2 and Figure 3.
In sum, the present invention can be effectively prevented the Internal Hole Deformation of rotor end face punching, improves and turns
Sub-dynamic balance stability, reduces mach operation sequence, improves production efficiency, and the present invention is to technique
Less demanding, make simple, can punching press assembling together with the motor rotor punching sheet of counter structure, install
Come very convenient.
