Abstract
The invention discloses a connecting structure of a cast-aluminum rotor ventilating channel. The connecting structure comprises a rotor punching sheet, rotor ventilating groove plates and a rotor ventilating groove tube, wherein at least one step surface is arranged at two ends of the rotor ventilating groove tube; and the rotor ventilating groove plates are arranged on the step surface and clamped between the rotor ventilating groove plates and the rotor punching sheet, so as to seal a cast-aluminum hole. The connecting structure of the cast-aluminum rotor ventilating channel has the advantages that the structure is simple and the cost is low; besides, the rotor ventilating groove plates do not need to be flanged, thereby saving tool equipment and working hours necessary for flanging; and each rotor ventilating groove plate is smooth, thereby guaranteeing that a finished product of the cast-aluminum rotor is not waved and eliminating the phenomenon that waste products are produced due to wave shapes.
Description
Technical field
The present invention relates to a kind of cast-aluminum rotor, relate in particular to a kind of cast-aluminum rotor air duct syndeton.
Background technology
As everyone knows, according to ventilation form, the squirrel-cage motor cast-aluminum rotor is divided into two kinds usually: no longitudinal ventilation road and the longitudinal ventilation road is arranged in the middle of unshakable in one's determination.In the cast-aluminum rotor that the longitudinal ventilation road is arranged; See also shown in Figure 1; Fig. 1 is the profile of traditional cast-aluminum rotor air duct syndeton; The design of conventional motors producer is normally: flange is carried out in the rotor ventilation frid 11 cast aluminium holes of cast-aluminum rotor punching 10 air duct both sides, connects with rotor ventilation barrel 12 then.The shortcoming of this kind project organization is: rotor ventilation frid 11 needs flange, wastes man-hour, affected by force behind the flange, and 11 out-of-flatnesses of rotor ventilation frid, distortion is serious, and cast-aluminum rotor is cast waveform easily and is caused scrapping.
Summary of the invention
The object of the present invention is to provide a kind of cast-aluminum rotor air duct syndeton; It has characteristics simple in structure, that cost is low, assurance finished product cast-aluminum rotor air duct does not have the waveform defective, to solve the problem that cast-aluminum rotor air duct syndeton exists in the prior art.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of cast-aluminum rotor air duct syndeton; It comprises rotor punching, rotor ventilation frid and rotor ventilation barrel; Wherein, the two ends of said rotor ventilation barrel offer at least one step surface, and said rotor ventilation frid is arranged on the step surface; And be stuck between rotor ventilation barrel and the rotor punching, seal up the cast aluminium hole.
Especially, a step surface is all offered at the two ends of said rotor ventilation barrel.
Especially, two-layer rotor ventilation frid is set on the said step surface.
Beneficial effect of the present invention does, said cast-aluminum rotor air duct syndeton is compared with existing structure, and not only simple in structure, cost is low; And the rotor ventilation frid need not flange, has saved necessary frock of flange and man-hour, every rotor ventilation frid all is smooth, guarantees that the finished product cast-aluminum rotor is no waveform, has stopped to produce because of waveform the phenomenon of waste product.
Description of drawings
Fig. 1 is the profile of traditional cast-aluminum rotor air duct syndeton,
The profile of the cast-aluminum rotor air duct syndeton that Fig. 2 provides for the specific embodiment of the invention 1.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
See also shown in Figure 2; The profile of the cast-aluminum rotor air duct syndeton that Fig. 2 provides for the specific embodiment of the invention 1, in the present embodiment, a kind of cast-aluminum rotor air duct syndeton comprises rotor punching 20, rotor ventilation frid 23 and rotor ventilation barrel 21; The two ends of said rotor ventilation barrel 21 offer a step surface 22; Said rotor ventilation frid 23 is arranged on the step surface 22, and is stuck between rotor ventilation barrel 21 and the rotor punching 20, seals up the cast aluminium hole.
On said each step surface 22 two-layer rotor ventilation frid 23 is set.
Above-mentioned cast-aluminum rotor air duct syndeton rotor ventilation frid 23 need not flange, as long as the cast aluminium hole is strengthened a little; Necessary frock of flange and man-hour have been saved.Stepped form is made at rotor ventilation barrel 21 two ends simultaneously; Block rotor ventilation frid 23 with step, both located rotor ventilation frid 23, sealed the cast aluminium hole again; It all is smooth making every rotor ventilation frid 23; Eliminated stress, guaranteed that the finished product cast-aluminum rotor is no waveform, has stopped to produce because of waveform the phenomenon of waste product.
Claims (3)
1. cast-aluminum rotor air duct syndeton; It comprises rotor punching, rotor ventilation frid and rotor ventilation barrel; It is characterized in that; The two ends of said rotor ventilation barrel offer at least one step surface, and said rotor ventilation frid is arranged on the step surface, and is stuck between rotor ventilation barrel and the rotor punching.
2. cast-aluminum rotor air duct syndeton according to claim 1 is characterized in that a step surface is all offered at the two ends of said rotor ventilation barrel.
