Abstract
The invention relates to a casting-aluminum rotor. The casting-aluminum rotor comprises a rotor body provided with a chamber, wherein the chamber is internally provided with a first punching sheet and at least two punching sheets, the second punching sheets are in a concave chamber below the first punching sheet, the first punching sheet is provided with a first mark groove, each second punching sheet is provided with a second mark groove, the second mark grooves are on one line, and the first mark groove and the second mark grooves are not on one line. The casting-aluminum rotor is advantaged in that the first mark groove on the first punching sheet and the second mark grooves of the second punching sheets in the chamber of the rotor body are arranged in a staggered mode, so the rotor structure is guaranteed, a use effect of the rotor is improved, and work efficiency of a motor is improved.
Description
Technical field
The present invention relates to a kind of cast-aluminum rotor.
Background technology
Cast-aluminum rotor mostly is the main rotating parts in dynamic power machine and work mechanism, the mark groove that the inner punching of existing rotor body is provided with in same groove, like this operating influence internal structure fragile, affected decline in useful life, Practical Performance declines, and has affected the work of motor.
Summary of the invention
The technical problem to be solved in the present invention is that internal rotor structure is fragile, has affected decline in useful life, thereby a kind of cast-aluminum rotor is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of cast-aluminum rotor, comprise the rotor body that is provided with cavity, in described cavity, be provided with the first punching, at least two the second punchings, described the second punching is positioned at the below cavity of the first punching, described the first punching is provided with the first mark groove, described every the second punching is provided with the second mark groove, described the second mark groove is on same straight line, and described the first mark groove and all the second mark grooves be not on same straight line.
Preferably, the outer wall of described rotor body is provided with at least one unwrapping wire groove, and the straight line at described unwrapping wire groove place and the straight line parallel at the second mark groove place, guaranteed rotor structure planarization, stable performance.
Preferably, the cross section of described the second mark groove is circular arc, and circular arc is easy to process, simple in structure, practical.
In sum, advantage of the present invention: the second mark groove that the first mark groove in the first punching being arranged in rotor body cavity and the second punching are provided with setting of staggering, guarantee rotor structure, improved the result of use of rotor, improved motor working efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of a kind of cast-aluminum rotor of the present invention.
Embodiment
As shown in Figure 1, a kind of cast-aluminum rotor, comprise the rotor body 1 that is provided with cavity 2, in described cavity 2, be provided with the first punching 31, at least two the second punchings 32, described the second punching 32 is positioned at the below cavity 2 of the first punching 31, described the first punching 31 is provided with the first mark groove 41, described every the second punching 32 is provided with the second mark groove 42, described the second mark groove 42 is on same straight line, described the first mark groove 41 and all the second mark grooves 42 are not on same straight line, the outer wall of described rotor body 1 is provided with at least one unwrapping wire groove 5, the straight line at described unwrapping wire groove 5 places and the straight line parallel at the second mark groove 42 places, guarantee rotor structure planarization, stable performance, the cross section of described the second mark groove 42 is circular arc, circular arc is easy to process, simple in structure, practical.
After rotor is coordinated with stator, being arranged on the first punching 31 in rotor body 1 cavity 2 covers being arranged on the second mark groove 4 that the second punching 32 is provided with, stator is coordinated in rotation process with rotor, and the power that rotor is subject to can cover the interior outflow of the first mark groove 14 from the first punching 31.
The second mark groove that the first mark groove in the first punching being arranged in rotor body cavity and the second punching are provided with setting of staggering, has guaranteed rotor structure, has improved the result of use of rotor, has improved motor working efficiency.
