Description
Technical field
The utility model relates to technical field of motors, is specially a kind of motor ventilating fan leaf.
Background technique
Motor ventilating fan is a kind of motor with fan hub and blade, an equally distributed groove is had along fan hub excircle, blade is inserted in groove, through welding, the permanent joining method such as bonding makes blade become to be integrated with fan hub, the whole machine balancing of motor ventilating fan is good, adjustment balance man-hours requirement can be saved, weight ratio Bolt Connection formula fan alleviates more than 30%, general fan leaf big city adopts the metals such as aluminum alloy to make, whole fan weight can be very large, mobile very inconvenience, in order to solve the problems such as weight, also the fan manufacturer had, all aluminium alloy is adopted to make fan leaf, but because aluminum-alloy fan leaf is easily aging, when high quick-action turns, ability to bear is limited, working life is not long, easily fracture, cause security incident, thus general all aluminium alloy fan leaf is only adapted to small-sized fans, and during fan leaf fixing, only be provided with a keyway, fixing not firm, also can have a huge impact motor operation.
Model utility content
The purpose of this utility model is to provide a kind of motor ventilating fan leaf, and to solve the problem proposed in above-mentioned background technology, structure is simple, reasonable in design.
For achieving the above object, the utility model provides following technological scheme: a kind of motor ventilating fan leaf, comprise flabellum, blade rack, axle sleeve and flabellum body, the upper surface of described flabellum body is provided with blade rack, the top of described blade rack is provided with flabellum fixed groove, is provided with flabellum in the inside of described flabellum fixed groove, and the upper surface of described flabellum body is provided with smooth curved surface, the inside of described flabellum body is provided with axle sleeve, and the inside of described axle sleeve is provided with keyway.
Preferably, die cast is passed through between described blade rack and flabellum body.
Preferably, be connected by retaining screw between described flabellum with flabellum fixed groove.
Preferably, the inside of described axle sleeve is provided with four keyways, and is uniformly distributed in axle sleeve between four keyways.
Preferably, the material of described blade rack and flabellum body is aluminum alloy, and all scribbles high-temperature resistant coating in aluminum alloy surface.
Preferably, the material of described flabellum is aluminum alloy.
Compared with prior art, the beneficial effects of the utility model are: a kind of motor ventilating fan leaf, and be provided with aluminum-alloy fan leaf and aluminum alloy blade rack, when high quick-action turns, ability to bear is stronger, longer service life is of a specified duration, not frangibility, easily changes flabellum, evenly scribbles high-temperature resistant coating in aluminum alloy surface, not oxidizable, decrease the impact on machine operation, vibration & noise operationally is all decreased, there is higher economic benefit and application prospect widely.
