Abstract
The utility model discloses an irregular ventilation grooved tube for a rotor, which comprises a tube body and a steel plate, wherein the tube body is connected with the steel plate through welding, the tube body is incised from an irregular steel tube with a thickness of 1.5mm, and the size of the steel plate is 1.5mm X 10mm. The irregular ventilation grooved tube has the beneficial effects that the ventilation grooved tube is manufactured both mechanically and manually, the manufacturing process is simple, and the ventilation grooved tube is made by a die through drawing and has high precision; the ventilation grooved tube has no opening at the tail part, so aluminum can not be leaked when aluminum is cast to the rotor; the irregular ventilation grooved tube can adopt an irregular steel tube with a thickness of 1mm to 2mm, and since the increase of the thickness leads to obvious size increase of the aluminum cast rotor of an electromotor, an aluminum cast rotor with big diameter can be cast, and the original rotor which is made of copper bars can be changed to be an aluminum cast rotor structure; the cost of the ventilation grooved tube is obviously reduced; and the ventilation grooved tube has good economic benefits.
Description
Technical field
The utility model relates to a kind of rotor parts of asynchronous motor, specifically a kind of rotor abnormity ventilation barrel.
Background technology
Present existing ventilation barrel is generally made by the steel plate of 1mm * 10mm is folding, and it makes more complicated by hand.For example, the rotor of a motor needs a hundreds of ventilation barrel, and many reaches thousands of, and the home built size and the depth of parallelism are difficult to guarantee, thereby must grind processing and finish on surface grinding machine; Owing to form by folding, so the position of afterbody bending is loosening easily, distortion, the easy opening of its afterbody when the rotor core lamination compresses can cause casting aluminum rotor hourglass aluminium, rotor slice, rotor broken bar, even the end ring of rotor has serious shortcoming, causes rotor to scrap; In addition, the thickness of ventilation barrel can only adopt the steel plate of 1mm, shaping difficulty when increasing thickness, and when cast-aluminum rotor was too big, existing ventilation barrel was out of shape because of not bearing too high pressure, therefore can only be applied on the less relatively rotor.
The utility model content
At above defective, the utility model provides a kind of and makes simply, not leakiness aluminium, the rotor abnormity ventilation barrel that can reduce cost, and can't guarantee more single defective in size and the depth of parallelism, the use to overcome existing product.
For achieving the above object, the utility model is by the following technical solutions:
A kind of rotor abnormity ventilation barrel comprises body and steel plate, and described body and steel plate are weldingly connected, and described body is formed for the cutting of 1.5mm chapped pipe, and described steel plate is of a size of 1.5mm * 10mm; Described body is the chapped pipe of thickness 1mm-2mm.
The beneficial effect of rotor described in the utility model abnormity ventilation barrel is: machine and manual simple in conjunction with making, and make and have a higher precision by die drawn; Its afterbody does not have opening, just can not cause leakage aluminium like this when casting aluminum rotor; The thickness of abnormity ventilation barrel can because the increase of thickness obviously strengthens the cast-aluminum rotor of motor, can be cast large diameter cast-aluminum rotor with the chapped pipe of 1mm～2mm, makes originally and can only also can change the cast-aluminum rotor structure into the rotor of copper bar; Cost obviously reduces, and has good economic benefit.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described rotor abnormity of the utility model embodiment ventilation barrel;
Fig. 2 is the end view of the described rotor abnormity of the utility model embodiment ventilation barrel.
Among the figure:
1, body; 2, steel plate.
Embodiment
Shown in Fig. 1-2, the described rotor abnormity of the utility model embodiment ventilation barrel comprises body 1 and steel plate 2, and described body 1 is weldingly connected with steel plate 2, and described body 1 is formed for the cutting of 1.5mm chapped pipe, and described steel plate 2 is of a size of 1.5mm * 10mm; Described body 1 is the chapped pipe of thickness 1mm-2mm.Body 1 is made by die drawn and is had higher precision; Its afterbody does not have opening, just can not cause leakage aluminium like this when casting aluminum rotor; Because the increase of thickness obviously strengthens the cast-aluminum rotor of motor, can cast large diameter cast-aluminum rotor, makes originally and can only also can change the cast-aluminum rotor structure into the rotor of copper bar.
