Abstract
The utility model relates to a cast-aluminum rotor which comprises a rotor body with a cavity, wherein a first stamped steel and at least two second stamped steel are arranged in the cavity, the second stamped steel is arranged in a concave cavity below the first stamped steel, a first marking groove is formed on the first stamped steel, a second marking groove is formed on each second stamped steel, the second marking grooves are in a same straight line, and the first marking groove and the second marking grooves are in different straight lines. The cast-aluminum rotor has the advantages that the first marking groove on the first stamped steel and the second marking grooves formed on the second stampings in the cavity of the rotor body are staggered, thus the constitutive property of the rotor is ensured, the using effect of the rotor is improved, and the working efficiency of a motor is increased.
Description
Technical field
The utility model relates to a kind of cast-aluminum rotor.
Background technology
Mostly cast-aluminum rotor is the main rotating parts in dynamic power machine and the work mechanism; The mark groove that the inner punching of existing rotor body is provided with is in the same groove, like this operating influence internal structure fragile, influenced decline in useful life; Practical Performance descends, and has influenced the work of motor.
The utility model content
The technical problem that the utility model will solve is that the internal rotor structure is fragile, has influenced 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 utility model is realized through following technical scheme: a kind of cast-aluminum rotor; Comprise the rotor body that is provided with cavity, be provided with first punching, at least two second punchings in the said cavity, said second punching is positioned at the below cavity of first punching; Said first punching is provided with the first mark groove; Said every second punching is provided with the second mark groove, and the said second mark groove is on the same straight line, and the said first mark groove and all second mark grooves be not on same straight line.
Preferably, the outer wall of said rotor body is provided with at least one unwrapping wire groove, and the straight line at said unwrapping wire groove place and the straight line parallel at second mark groove place have guaranteed the rotor structure planarization, stable performance.
Preferably, the cross section of the said second mark groove is circular arc, and circular arc is easy to process, and is simple in structure, practical.
In sum; The advantage of the utility model: will be arranged on the setting of staggering of the second mark groove that the first mark groove and second punching in first punching in the rotor body cavity be provided with; Guarantee rotor structure property, improved the result of use of rotor, improved motor working efficiency.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of a kind of cast-aluminum rotor of the utility model.
Embodiment
As shown in Figure 1, a kind of cast-aluminum rotor comprises the rotor body 1 that is provided with cavity 2; Be provided with first punching 31, at least two second punchings 32 in the said cavity 2, said second punching 32 is positioned at the below cavity 2 of first punching 31, and said first punching 31 is provided with the first mark groove 41; Said every second punching 32 is provided with the second mark groove 42, and the said second mark groove 42 is on the same straight line, and the said first mark groove 41 and all second mark grooves 42 are not on same straight line; The outer wall of said rotor body 1 is provided with at least one unwrapping wire groove 5, and the straight line parallel at the straight line at said unwrapping wire groove 5 places and the second mark groove, 42 places has guaranteed the rotor structure planarization; Stable performance, the cross section of the said second mark groove 42 is circular arc, and circular arc is easy to process; Simple in structure, practical.
With rotor with after stator cooperates; Being arranged on first punchings 31 in rotor body 1 cavity 2 will be arranged on the second mark groove 4 that second punching 32 is provided with and cover; Stator is cooperated in the rotation process with rotor, and the power that rotor receives can cover in the first mark groove 14 from first punching 31 and flow out.
The second mark groove that the first mark groove in first punching that is arranged in the rotor body cavity and second punching are provided with setting of staggering has guaranteed rotor structure property, has improved the result of use of rotor, has improved motor working efficiency.
