Abstract
The utility model relates to fan blades of a motor rotor, which is characterized by comprising an annular plastic basal body connected with a cast aluminum rotor. The basal body is uniformly provided with a plurality of plastic fan blades which are in a Y shape, the opening of each fan blade is inward, two outer sides are in an arc shape, and the section of each fan blade is trapezoidal. Two-side bevel edges are in a five-degree included angle, and the basal body between the two fan blades is provided with a balanced hole. The fan blades of the motor rotor has the advantages of reasonable design, simple structure, easy manufacture, convenient installation and use, high production efficiency, effectively reduces the production cost, and increases the product quality. The operating radiating effect of a motor is good.
Description
Technical field
The utility model relates to middle-size and small-size threephase asynchronous field, specifically a kind of fan blade of rotor.
Background technology
The fan blade of existing middle-size and small-size threephase asynchronous rotor generally is that cast aluminium is made, and adopts extrusion process that fan blade and rotor aluminium ring are become one.Promptly carry out in the process of die casting aluminium at rotor, fan blade is cast simultaneously, has increased the aluminium amount of using.When die casting aluminium, because fan blade and rotor aluminium ring are one casting flaws such as shrinkage cavity, disconnected bar, slice appear easily.When defective appearred in fan blade, whole rotor can become waste product, has increased production cost.In addition, because the casting aluminum rotor fan blade is a linear pattern, the air-flow that produces in motor operation course can not directly act on rotor, so radiating effect is undesirable.The shape of rotor fan blade of only changing could improve radiating effect, and fan blade is separated from rotor aluminium ring one, makes fan blade with the plastics that cost is low.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of simple in structure, reasonable in design, easily makes, and cost is low, the fan blade of the rotor of good heat dissipation effect.
The utility model solves the scheme that its technical problem takes: a kind of fan blade of rotor, it is characterized in that being provided with the plastic annular matrix that is connected with cast-aluminum rotor, evenly be provided with several plastic blades on the matrix, fan blade is the Y type, opening is inside, and two outsides are curved, and the fan blade cross section is trapezoidal, the both sides hypotenuse is 5 degree angles, is provided with balancing hole on the matrix between two fan blades.
The wind direction that is formed by the structure of fan blade directly acts on stator, the motor operation good heat dissipation effect, and fan blade is molded with plastic mold injection, makes the precision height, and production cost is low, and is easy for installation, and rotor weight is reduced, and reduced the moment of inertia of motor.
The utility model is reasonable in design, and is simple in structure, easy to manufacture, easy to install, and the production efficiency height can reduce production costs effectively, improves the quality of products.
The utility model is described in detail by embodiment below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is an installation diagram of the present utility model.
Mark among the figure: 1, rotor, 2, fan blade.
Embodiment
By Fig. 1, Fig. 2, shown in Figure 3, a kind of fan blade of rotor, it is provided with the plastic annular matrix that is connected with cast-aluminum rotor 1, evenly be provided with several plastic blades 2 on the matrix, fan blade is the Y type, and opening B is inside, the curved R in two outsides, the fan blade cross section is trapezoidal, and the both sides hypotenuse is 5 degree angles, is provided with balancing hole on the matrix between two fan blades.
Because two outsides of fan blade are curved, rotor just or the counter-rotating fan blade all can produce air quantity, and wind direction is directly to stator, good heat dissipation effect during motor operation; The plastic blade presentation quality is good, and is easy for installation, and the annular matrix riveting of plastic blade is got final product on rotor; Can when rotor dynamic balancing, replace original balance aluminum post riveting balance pad technology, in balancing hole, add the balance clay and carry out balance and get final product.
With the Y132 motor is example, 0.12 kilogram of the weight of separate unit motor use aluminium fan blade, and 16.6 yuan/kilogram of unit prices, cost are 2 yuan; 0.055 kilogram of plastic blade weight of the present utility model, only 1.1 yuan of 20 yuan/kilogram of unit prices, cost, cost can reduce by 45%.
