Description
Technical Field
The utility model relates to a motor manufacturing technology field refers in particular to a quick mounting structure of motor fan blade.
Background
The motor is widely applied to various products in various industries, is a core component for generating kinetic energy, and is easy to generate high temperature, so that a cooling effect is achieved by arranging heat dissipation fan blades on a rotor, and the motor is particularly suitable for a motor with high torque and high rotating speed; the cooling effect is achieved through the heat dissipation fan blades, so that the service life of the motor is prolonged.
The existing motor fan blade mounting structure adopts nuts to fix fan blades on a rotor shaft, so that the mounting mode is low in production efficiency, and the nuts are loosened after the motor is used for a long time, so that the fan blades can slip on the rotor shaft, and the heat dissipation is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a quick mounting structure of motor fan blade through the cooperation in axle and hole, solves the long-time problem that can become flexible of nut that uses.
The purpose of the utility model is realized like this: the utility model provides a quick mounting structure of motor fan blade, includes motor shaft, and the fan blade is installed to motor shaft's periphery, and the up end shaping of fan blade has annular installation department, has seted up power supply machine shaft male mounting hole in the annular installation department, the side shaping of motor shaft upper end has a spacing plane, the shaping has spacing groove one with spacing plane complex in the mounting hole, the elastic tank has been seted up on the annular installation department, the upper end shaping of annular installation department has the spacing portion of inside extension, motor shaft's upper end periphery shaping has the spacing groove two that supplies spacing portion card to establish.
Preferably, the fan blade includes circular installation department, is provided with a plurality of flabellum on the circular installation department.
Preferably, the fan blades are integrally formed by injection molding.
Preferably, the number of the elastic grooves is three, and the annular mounting portion is divided into three elastic lobes.
Compared with the prior art, the utility model has the advantages that:
the utility model discloses a cooperation in axle and hole realizes the quick installation between fan blade and the motor shaft, convenient assembling, and production efficiency is high, and prior art compares, need not extra fastener and carries out fixed mounting, and is with low costs, also can not become flexible long service life under permanent use.

Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1-4, a quick mounting structure of motor fan blade, including motor shaft 1, fan blade 2 is installed to motor shaft 1's periphery, and the up end shaping of fan blade 2 has annular installation department 3, has seted up power supply motor shaft 1 male mounting hole 4 in the annular installation department 3, the side shaping of motor shaft 1 upper end has spacing plane 5, the shaping has spacing groove one 6 with spacing plane 5 complex in the mounting hole 4, set up flexible groove 7 on the annular installation department 3, the shaping of annular installation department 3's upper end is to the spacing portion 8 of inside extension, the shaping of motor shaft 1's upper end periphery has the spacing groove two 9 that supplies spacing portion 8 card to establish.
The utility model discloses a cooperation in axle and hole realizes the quick installation between fan blade and the motor shaft, convenient assembling, and production efficiency is high, and prior art compares, need not extra fastener and carries out fixed mounting, and is with low costs, also can not become flexible long service life under permanent use.
When the fan blade 2 is inserted into the periphery of the motor rotating shaft 1, the limiting plane 5 is firstly aligned with the limiting groove I6 and then is installed, then the limiting part 8 is clamped in the limiting groove II 9, so that the fan blade is prevented from falling off from the motor rotating shaft, a self-locking fixed connection structure is formed, the motor rotating shaft can drive the fan blade to keep synchronous rotation due to the matching of the limiting plane 5 and the limiting groove I6, the connection structure is simple, and the manufacturing cost is low.
The fan blade 2 comprises a circular mounting part 10, and a plurality of fan blades 11 are arranged on the circular mounting part 10.
The fan blade 2 is formed integrally by injection molding, and is convenient to produce and manufacture.
The quantity of elastic groove 7 is three, and divide into three elasticity lamella 12 with annular installation portion 3, the upper end of elasticity lamella 12 inwards extends limited part, so that install, the diameter size that forms between three elasticity lamella 12 slightly is less than motor shaft's diameter size, consequently when motor shaft passes through annular installation portion, will outwards extrude the elasticity lamella, make it take place elastic deformation, go into two 9 spacing grooves up to spacing portion card, go into one instant in two 9 spacing grooves as spacing portion card, can send clear and brittle sound because the collision between the two, thereby the suggestion has assembled in place.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
