Abstract
The utility model relates to a draught fan spring washer which comprises a fixing ring. A plurality of reinforcing ribs evenly distributed in a circumferential mode are arranged on the upper end face and the lower end face of the fixing ring, a plurality of first supporting legs are arranged on the inner side wall of the fixing ring, and second supporting legs are arranged between the adjacent two first supporting legs. According to the draught fan spring washer, the first supporting legs and the second supporting legs are arranged on the inner side wall of the fixing ring, the first supporting legs and the second supporting legs can support the inner ring of a bearing well, meanwhile the reinforcing ribs evenly distributed in the circumferential mode are arranged on the upper end face and the lower end face of the fixing ring, the integral supporting intensity is high, stability is high, and the service life of a draught fan can be prolonged greatly.
Description
Technical field
The utility model relates to a kind of blower fan bullet pad.
Background technique
Blower fan is one of equipment of generally using of each factory, enterprise, and particularly the application of blower fan is more extensive.Boiler air blast, removing smoke and dust, the cooling blower fan that all be unable to do without of ventilation, in power station, mine, chemical industry and environment-friendly engineering, blower fan is indispensable visual plant especially.But simple for the bullet mat structure of spring bearing in blower fan at present, intensity is low, and support effect is poor, easily causes the unstable of fan operation, affects the working life of blower fan.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of blower fan bullet pad simple in structure, easy to use.
Blower fan bullet pad of the present utility model, comprise retainer ring, in the upper and lower both ends of the surface of described retainer ring, be equipped with some stiffening ribs that are circularly and evenly distributed, the madial wall of retainer ring is provided with some the first supporting foots, between adjacent two the first supporting foots, is provided with the second supporting foot.
Compared with prior art the beneficial effects of the utility model are: blower fan bullet pad of the present utility model by being provided with some the first supporting foots and the second supporting foot on the madial wall of retainer ring, the first supporting foot and the second supporting foot can be good at the inner ring of spring bearing, in the upper and lower both ends of the surface of retainer ring, be equipped with some stiffening ribs that are circularly and evenly distributed simultaneously, integrated support intensity is high, stability is high, can greatly improve the working life of blower fan.
