Description

Motor of fan with straight slot and bent blades

Technical Field

The utility model relates to a motor especially relates to a take motor of bent blade fan in straight groove suitable for pump.

Background

The existing motor comprises a rotor and a fan arranged on a rotating shaft of the rotor, wherein the rotating shaft penetrates through a central shaft hole in the fan, and a straight groove is formed in the end part of the rotating shaft. When the motor is applied to the water pump, before starting, whether the water pump is blocked or not needs to be confirmed, if the water pump is blocked, the motor is forcibly electrified, and the condition that the motor is burnt out easily occurs. Therefore, a straight groove is processed on the rotor, and then the rotating shaft is twisted by a straight groove screwdriver to confirm whether the water pump is locked or not, so that the condition that the motor is burnt is avoided. However, the machining of the linear groove on the rotating shaft requires an additional machining process, which increases the machining cost.

Disclosure of Invention

An object of the utility model is to solve the above-mentioned problem that prior art exists and provide a take motor of crooked blade fan in straight line groove, set up the recess on the fan for tools such as bottle opener insert the recess and rotate the pivot, because the fan forms for plastics material is moulded plastics, the recess can directly form at the in-process of injection moulding fan through the mould, need not to increase manufacturing procedure separately, avoid increasing the processing cost, can also act on the recess through tools such as bottle opener and make the pivot rotate and examine whether the water pump blocks.

The above technical purpose of the present invention is mainly solved by the following technical solutions: the motor of the fan with the bent blades and the straight grooves comprises a machine shell, a rotor assembly arranged in the machine shell, a fan arranged on a rotating shaft of the rotor assembly, and a fan cover arranged on the periphery of the fan. Offer the recess on the fan for instruments such as bottle opener insert the recess and rotate the pivot, because the fan forms for plastics material moulding plastics, the recess can directly form at the in-process of injection moulding fan through the mould, need not to increase manufacturing procedure separately, avoids increasing the processing cost, can also act on the recess through instruments such as bottle opener and make the pivot rotate and examine whether the water pump blocks.

As further improvement and supplement to the above technical scheme, the utility model discloses a following technical measure:

the cap and the ring plate are of an integral structure.

The groove is a straight groove, a cross groove or an inner hexagonal groove, and the cap is sleeved at the end part of the rotating shaft.

The flabellum is the curved blade of divergent type, the flabellum is central symmetry and distributes. The fan has the advantages that the fan efficiency can be increased by adopting the bent blades, the diameter of the fan can be reduced to a certain degree, the cost is reduced, the area is reduced, and the noise can be reduced to a certain degree.

The fan cover is a hollow fan cover, and the fan cover is correspondingly arranged in the hollow corresponding to the groove. The hollows on the fan cover are distributed according to a certain rule, wherein the corresponding position of the groove at least corresponds to one hollow, so that tools such as a screwdriver and a screwdriver can act on the groove conveniently.

The utility model discloses beneficial effect who has: the fan is made of plastic materials in an injection molding mode, the groove can be directly formed in the process of injection molding of the fan through a mold, additional machining procedures are not needed, machining cost is avoided being increased, and the rotating shaft can be rotated through the action of tools such as a screw driver and the like on the groove to check whether the water pump is locked or not; the bent blade structure has large air volume, so that the cooling effect can be ensured even if the outer diameter is reduced, the material is saved, and the noise is lower.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): as shown in fig. 1 and 2, the motor of the curved blade fan with the straight groove comprises a casing 1, a rotor assembly arranged in the casing, a fan 2 arranged on a rotating shaft of the rotor assembly, and a fan cover 3 covering the periphery of the fan, wherein the fan comprises a ring plate 21 with a central shaft hole, fan blades 22 standing on the ring plate, and a cap 23 matched with the central shaft hole, wherein a groove 24 is arranged on the outer end face of the cap, and the groove is used for rotating the rotor in cooperation with a tool. Offer the recess on the fan for instruments such as bottle opener insert the recess and rotate the pivot, because the fan forms for plastics material moulding plastics, the recess can directly form at the in-process of injection moulding fan through the mould, need not to increase manufacturing procedure separately, avoids increasing the processing cost, can also act on the recess through instruments such as bottle opener and make the pivot rotate and examine whether the water pump blocks.

As further improvement and supplement to the above technical scheme, the utility model discloses a following technical measure: the cap 23 is of unitary construction with the ring plate 21.

The groove 24 is a straight groove, a cross groove or an inner hexagonal groove, and the cap is sleeved at the end part of the rotating shaft.

The fan blades 22 are divergent curved blades, and are distributed in a centrosymmetric manner. The fan has the advantages that the fan efficiency can be increased by adopting the bent blades, the diameter of the fan can be reduced to a certain degree, the cost is reduced, the area is reduced, and the noise can be reduced to a certain degree. The bent blade structure has large air volume, so that the cooling effect can be ensured even if the outer diameter is reduced, the material is saved, and the noise is lower. In the following figure, when the outer diameter of the fan is D, the thickness of the blades is T, and the small radius of the blades is about 0.4 times the outer diameter of the fan (the center of the circle is on the other blade), the number of the blades is odd, generally 5 or 7, and the cooling effect and the noise reach the optimal values.

The fan cover 3 is a hollow fan cover, and the position of the fan cover corresponding to the groove is correspondingly hollow. The hollows on the fan cover are distributed according to a certain rule, wherein the corresponding position of the groove at least corresponds to one hollow, so that tools such as a screwdriver and a screwdriver can act on the groove conveniently.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. In the above embodiments, the present invention may be variously modified and changed. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
