Abstract
The utility model relates to a double-layer type generator heat-radiation fan blade. The center of the generator heat-radiation fan blade with a shaft sleeve is provided with a shaft hole, and the periphery of the shaft hole is provided with a blade disk which is in an integral structure. The generator heat-radiation fan blade is characterized in that the shaft sleeve which can resist the temperature of 240 DEG C and is made from nylon 6 is arranged in the shaft hole. Compared with the prior art, the utility model has the advantages of simple structure, easy processing, lower cost, good heat resistance and long service life.
Description
Technical field:
The utility model relates to a kind of two-layer equation generator heat radiation fan blade.
Background technology:
Existing generator heat radiation fan blade generally all adopts common duroplasts single injection-molded, the generator heat radiation leaf blade that the common duroplasts of this employing is made is harder, and thermal endurance is relatively poor, because the generator of aluminum coil can produce higher (about 210 ℃) temperature in the course of the work, if therefore adopt above-mentioned generator heat radiation fan blade, tend to dispel the heat partial melting that fan blade and alternator shaft directly contact and produce distortion of generator, make the fan blade rotation unstable, the useful life of also so greatly having lowered fan blade.
Summary of the invention:
The purpose of this utility model is to provide a kind of cost lower, and better stable on heating two-layer equation generator heat radiation fan blade is arranged again.
The technical solution of the utility model is as follows: the generator heat radiation fan blade of tape spool cover of the present utility model, be provided with axis hole at the center, around axis hole, be provided with the leaf dish that is structure as a whole, it is characterized in that: in axis hole, be provided with the axle sleeve of making by the nylon 6 that can tolerate 240 ℃.
The utility model compared with prior art has that simple in structure, handling ease, cost are lower, an advantage of good heat resistance, long service life.
Description of drawings:
Fig. 1 is a structure schematic diagram of the present utility model.
Fig. 2 is the A-A sound view of Fig. 1.
Fig. 3 is the Facad structure schematic diagram of utility model.
Fig. 4 is the structure schematic diagram of axle sleeve.
Fig. 5 is the Facad structure schematic diagram of axle sleeve.
Fig. 6 is the side structure schematic diagram of axle sleeve.
Label declaration: 1 axle sleeve, 2 leaf dishes, 3 blades, 4 little grooves, 5 louvres, 6 reinforcements, 7 keyways.
Embodiment:
Shown in Fig. 1-6, the generator heat radiation fan blade of tape spool of the present utility model cover 1, be in traditional use decades, be provided with axis hole at the center, around axis hole, be provided with and the axle sleeve that 240 ℃ nylon 6 makes that can tolerate with toughness is set in the axis hole of generator heat radiation fan blade of the leaf dish 2 that is structure as a whole makes.
Axle sleeve of the present utility model is embedded in the axis hole of band fan blade tightly by the method for quadric injection mould.Be provided with some little grooves 4 in the appearance side of axle sleeve, so that the liquid material of leaf dish can be filled in these grooves when quadric injection mould, behind the cooling curing, the contact-making surface of axle sleeve and leaf dish can closely be cross-linked and be integral, stability and fastness when having guaranteed to use; Its one side (leaf dish front) of leaf dish described in the utility model is the shape in the plate front of band edge, try to get to the heart of a matter and the outer side edges of axis hole along between be provided with reinforcement 6, be provided with at the another side (being the leaf dish back side) of leaf dish and fuse with the plate back side and perpendicular to some blades 3 at the plate back side, blade extends to a page web edge from the axis hole end always.The axle sleeve side that is positioned at the leaf dish back side is provided with louvre 5, and louvre is through hole or blind hole.When adopting blind hole, that axle sleeve can be produced is thinner, and one side helps heat radiation, can also help guaranteeing the useful life of axle sleeve on the other hand on the basis of saving the axle sleeve cost of raw material, can reach two at one stroke effects that get.Then axle sleeve should be thicker to adopt through hole, and the cost of raw material is higher.Be provided with keyway 7 in the axle sleeve inboard.The leaf dish adopts the J-340 engineering plastics with toughness in Nanjing to make.
