Abstract
The utility model discloses a special fan used for a YB3-series flame-proof three-phase asynchronous motor, which comprises a fan body, vanes and a shaft sleeve which are arranged on the fan body, wherein the shaft sleeve is provided with two elastic clamping blocks; the shape of the elastic clamping blocks is matched with that of the outer periphery of a shaft of the fan; a positioning block is arranged on the inner periphery of the shaft sleeve; and the shaft sleeve of the fan body has a single-layer structure. The shaft sleeve adopts the single-layer structure instead of a double-layer structure, the fan is made of glass fiber reinforced polypropylene, and the single-layer structure can meet the requirements on strength and reliability, thus saving part of raw material by adopting the single-layer structure; and more importantly, the single-layer shaft sleeve structure of the fan simplifies the die technique of the fan, improves the working efficiency, further reduces the production cost, and leads to obvious improvement on the basis of the original structure.
Description
Technical field
The utility model belongs to the motor component technical field, particularly a kind of YB3 series flame-proof type threephase asynchronous dedicated fan.
Background technique
At present, the self-clamping type motor ventilating fan is subjected to liking of user deeply with its simple structure and good usability, this fan processing, easy and simple to handle.China utility model patent CN200720092352.X discloses a kind of like this fan, and this patent comprises fan body and the flabellum that is connected as a single entity with fan body, in the central shaft hole of fan body, is provided with key link and Flexible Connector with the fan body one.And on the central shaft hole inwall of fan body, also be provided with the clamping inner convex platform.This model utility has solved assembling procedure complexity in the known technology well, and it is many to consume metallic material, problems such as cost of production height.But because this model utility also is provided with the clamping inner convex platform on the inwall of central shaft hole, key link and Flexible Connector are arranged on the inner convex platform, operation is more complicated still, in the processing that is connected mould between inner convex platform and the central shaft hole certain degree of difficulty is arranged also, and the structure of double-deck axle sleeve has also increased cost of material.
The model utility content
The utility model provides the YB3 series flame-proof type threephase asynchronous that a kind of manufacturing process is more simple, raw material are more saved dedicated fan.
A kind of YB3 series flame-proof type threephase asynchronous dedicated fan, comprise fan body, be arranged on flabellum, axle sleeve on the fan body, two flexible clamping pieces are set on the described axle sleeve, the shape of described flexible clamping piece and the outer circumferential shape of fan shaft adapt, on the axle sleeve inner circumference positioning block is set, the axle sleeve on the described fan body is a single layer structure.
Described fan body is provided with removal hole.
The material of described fan is a glass fiber reinforced polypropylene.
Because the utility model YB3 series flame-proof type threephase asynchronous dedicated fan changes the structure of double-deck axle sleeve into single layer structure, and the employing of the material of fan is glass fiber reinforced polypropylene, single layer structure can satisfy the needs of intensity and reliability, change single layer structure like this into and both saved a part of raw material, what is more important, the solid bearing bush designs simplification of fan the mould process of fan, improved working efficiency, further reduced cost of production, on the basis of original structure, have significant progress.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of YB3 series flame-proof type threephase asynchronous dedicated fan, comprise fan body 1, be arranged on flabellum 2, axle sleeve 3 on the fan body 1, two flexible clamping pieces 5 are set on the described axle sleeve 3, the shape of described flexible clamping piece 5 and the outer circumferential shape of fan shaft adapt, on axle sleeve 3 inner circumferences positioning block 6 is set, the axle sleeve 3 on the described fan body 1 is single layer structures.
Described fan body 1 is provided with removal hole 4.Be convenient to dismounting dedicated fan disclosed in the utility model on the motor.The material of described fan is a glass fiber reinforced polypropylene.Glass fiber reinforced polypropylene is a kind of composite material (Composite materials), is to be matrix (Matrix) with a kind of material polypropylene, and another kind of material glass fiber is for strengthening the material that body (reinforcement) combines.Various materials make up for each other's deficiencies and learn from each other on performance, produce synergistic effect.
