Abstract
The utility model discloses an exhaust fan for a high-speed single brace electric generator. A plurality of blades are uniformly distributed on the outer diameter surface of a shaft sleeve; a back circular ring is fixedly connected to the rear upper side of each blade; and the front end of the shaft sleeve is provided with a conical ring. The exhaust fan has the advantages of low cost due to the adoption of ordinary thin steel sheets, simple manufacturing process, easy implementation, uncomplicated structure and high reliability.
Description
Technical field
The utility model relates to a kind of ventilating fan, relates in particular to the single ventilating fan that supports the generator use of a kind of high speed.
Background technique
Motor ventilating fan structure has been saved the required model of casting forming by the steel plate welding forming, is particularly suitable for the trial-production of motor new product.Because single support motor is connected with motor with connecting sheet, hand will pass the ventilating fan position and operates when connecting sheet is installed, so ventilating fan front end conical ring external diameter must be less than blades height, sending out in product in the past blade existing can crack on the path position outside conical ring, although, this phenomenon occurred with the blade thickening.
Summary of the invention
The purpose of this utility model has been to provide a kind of high speed the single ventilating fan that generator uses, this ventilating fan saving material, rugged construction of supporting.
The utility model is achieved like this, it comprises back annulus, blade, conical ring, axle sleeve, it is characterized in that even some blades that distribute of external diameter surface of axle sleeve, and the back upper place of blade is fixed with the back annulus, and the front end of axle sleeve is provided with conical ring.
Described blade bending edges becomes L shaped.
Technique effect of the present utility model is: 1, adopt general sheet metal, and with low cost; 2, manufacturing process is simple, implements easily; 3, structure is uncomplicated, the reliability height.
Description of drawings
Fig. 1 is a sectional drawing of the present utility model.
Fig. 2 is a plan view of the present utility model.
Back annulus 2, blade 3, conical ring 4, axle sleeve in the drawings, 1,
Embodiment
As shown in Figure 1 and Figure 2, the utility model is achieved like this, axle sleeve 4 is at the center, conical ring 3 is at the front end of axle sleeve 4, blade 2 evenly distributes around axle sleeve 4 external diameters, and back annulus 1 is in the back upper place of blade 2, integral weld forming, blade 2 bending edges wherein become L shaped, strengthened the intensity of blade 2, conical ring 3 planes and blade 2 plane contact, soldering point is at the dual-side of blade plane, improve welding reliability, thereby solved the problem that blade 2 cracks.
Claims (2)
1. a high speed list supports the ventilating fan that generator uses, and it comprises back annulus, blade, conical ring, axle sleeve, it is characterized in that some blades of the even distribution of external diameter surface of axle sleeve, and the back upper place of blade is fixed with the back annulus, and the front end of axle sleeve is provided with conical ring.
2. the single ventilating fan that supports the generator use of a kind of high speed according to claim 1 is characterized in that described blade bending edges becomes L shaped.
