Abstract
The utility model discloses a rotor iron ring of a frequency conversion brushless direct current motor. The rotor iron ring is formed by rolling a steel bar into the shape of a ring, wherein the height of an outer wall of the iron ring is greater than that of an inner wall of the rotor iron ring; the iron ring is formed by connecting the steel bar by welding; a welding part is the head and the tail of the steel bar; and a groove is reserved in the welding part. Compared with a bowl-shaped rotor, the rotor iron ring disclosed by the utility model has the beneficial effect that the consumption of a raw material of the steel is reduced, the cost of the rotor is reduced, the processing technology is simple, the dimensions of products are easily controlled, the installation position of a magnetic tile can be located, and the installation efficiency of the magnetic tile is improved.
Description
Technical field
The utility model relates to field of mechanical technique, relates in particular to the structure of frequency conversion brushless DC motor rotor.
Background technology
In the frequency conversion brushless direct current machine of routine, the rotor of employing is to become a bowl-shape product by a stretching sheet material by Mould Machining.This bowl structure exists materials many, and processing dimension is difficult to the shortcomings such as control.
The utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of rotor iron ring.
Complete skill scheme of the present utility model is that a kind of rotor iron ring, described rotor iron ring are the iron rings that is rolled into cast by a steel bar.
Alternatively, the outer layer height of described rotor iron ring is higher than the interior layer height of described rotor iron ring.
Alternatively, described rotor iron ring connects lopping by welding with described steel bar, and wherein, the welding position is the head and the tail of described steel bar.
Alternatively, there is a groove welding position of described rotor iron ring.
Therefore the bowl-shape rotor with respect to prior art the utlity model has following beneficial effect:
Because rotor is iron ring, has reduced the steel plate consumption of bottom surface and the waste material that falls, reduce the cost of rotor, and adopt conventional process technology, the energy simplified processing process is more easily controlled product size.
In addition, because rotor iron ring outer wall height is higher than inwall, so that iron ring is when installing with mould, the centrally aligned of guiding iron ring and mould, efficient and the convenience of raising installation magnetic shoe.
At last, because there is a groove welding position of rotor iron ring, make things convenient for the magnetic shoe location, guarantee the welding position between two magnetic shoes, the adverse effect of avoiding the welding position to cause in the magnetic shoe centre.
In sum, the utility model can reduce the raw material of steel in a large number, reduce the cost of rotor, and processing technology is simple, and product size is easily controlled.
Description of drawings
Accompanying drawing described herein is used to provide a further understanding of the present invention, consists of the application's a part, does not consist of to improper restriction of the present invention, in the accompanying drawings:
Fig. 1 is the vertical view of utility model.
Fig. 2 is the front section view of utility model.
Fig. 3 is the splicing part schematic diagram of utility model.
Fig. 4 is the magnetic shoe scheme of installation of utility model.
Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Embodiment 1:
The present embodiment provides a kind of rotor iron ring, and this is applicable to the frequency conversion brushless direct current machine.
Referring to Fig. 1 and Fig. 2, Fig. 1 is the vertical view of rotor iron ring, and Fig. 2 is the front section view of rotor iron ring.In the present embodiment, the rotor iron ring is the iron ring that is rolled into cast by a steel bar.Wherein, Reference numeral 101 is the groove location on the rotor iron ring welding position.
Referring to Fig. 3, Fig. 3 is the position view of rotor iron ring splicing.In the present embodiment, the rotor iron ring connects lopping by welding with steel bar, and the position of welding is the head and the tail of described steel bar.There is a groove 301 welding position of rotor iron ring.
Referring to Fig. 4, Fig. 4 is the scheme of installation of rotor iron ring and magnetic shoe.Because the welding position of rotor iron ring 401 is provided with a groove 403, when iron ring 401 was installed magnetic shoe 402, groove 403 was chimeric with mould, is used for the position of location magnetic shoe, guarantee the welding position between two magnetic shoes 402, the harmful effect of avoiding the welding position to cause in single magnetic shoe centre.
In the present embodiment, the layer wall height of rotor iron ring is higher than internal layer, so that the edge of rotor iron ring forms a gradient.When iron ring and mould installation, because the existence of gradient can guide the iron ring center to aim at mold center, improve installation effectiveness.
Therefore the bowl-shape rotor with respect to prior art the utlity model has following beneficial effect:
Because rotor is iron ring, has reduced the steel plate consumption of bottom surface and the waste material that falls, reduce the cost of rotor, and adopt conventional process technology, the energy simplified processing process is more easily controlled product size.
In addition, because the outer layer height of rotor iron ring is higher than internal layer, when iron ring and mould installation, the centrally aligned of iron ring and mould be can guide, efficient and convenience that magnetic shoe is installed improved.
At last, because there is a groove welding position of rotor iron ring, make things convenient for the magnetic shoe location, guarantee the welding position between two magnetic shoes, the adverse effect of avoiding the welding position to cause in the magnetic shoe centre.
In sum, the utility model can reduce the raw material of steel in a large number, reduce the cost of rotor, and processing technology is simple, and product size is easily controlled.
The above technical scheme that the embodiment of the invention is provided is described in detail, used specific case herein principle and the execution mode of the embodiment of the invention are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, all will change on embodiment and range of application, in sum, this description should not be construed as limitation of the present invention.
