Abstract
A motor which is good in heat radiation effect comprises a motor casing, a motor front cover, a motor rear cover and a motor rotor. A fan blade is fixed on the motor rotor. Through holes are arranged among the motor housing, the motor front cover and the motor rear cover. A clamping ring is also arranged on the motor rotor. The clamping ring is arranged near the fan blade and restricts axial movements of the fan blade. A clamping groove is arranged in the motor rotor. An insertion block which is matched with the clamping groove is arranged on a position, corresponding to the clamping groove, of the fan blade. According to the motor which is good in heat radiation effect of the novel structure, the through holes are arranged in the casing, the front cover and the rear cover of the motor; the fan blade is arranged on the rotor, so that driven by the blade, heat inside the motor is discharged outside the motor in the operation of the motor. The integral structure is simple and the operation is convenient.

Background technology
In the historical progress of human social development, the energy is the material base that the mankind depend on for existence forever, science and technology progress especially with the energy obtain conversion utilize be closely connected together with.Because production and the utilization of electric energy more relate to the conversion between mechanical energy and two kinds of form energy of electric energy, motor is as the equipment present position key of energy converting between mechanical, make the development of motor technology be directly connected to efficient transformation and the utilization of the energy, the exploitation of the energy and saving.
Motor is in the process of high speed load, and easily temperature rise is too fast, and in the time reaching the temperature of thermostat, motor has just stopped operation, has affected the operating time of motor, and easily causes the phenomenon of burning machine.
Utility model content
The purpose of this utility model is to provide a kind of too fast phenomenon of temperature rise that overcomes, and lengthens working hours, and has improved the motor of the good heat dissipation in useful life.
For solving the problems of the technologies described above, the utility model provides a kind of motor of good heat dissipation, comprise motor case, front motor cover, motor rear cover and rotor, on described rotor, be fixed with fan blade, between described motor housing, front motor cover and motor rear cover, be provided with through hole, on described rotor, be also provided with snap ring, described snap ring is arranged on fan blade side and limits fan blade and moves axially, on described rotor, be provided with draw-in groove, the corresponding slot of described fan blade installs and is equipped with the inserted block suitable with draw-in groove.
The utility model improves to be had, the wheel hub that described fan blade comprises blade and is connected with the output shaft of motor, and described blade is being arranged on wheel hub of divergent shape, and the trailing edge of described blade offers serrated slot, and the degree of depth of described serrated slot is 5-10mm.
The utility model improves to be had, and described blade is increased gradually by root to the serrated slot degree of depth at top.
The utility model improves to be had, and on the lee face of described blade, is extended with groove from rectangular channel to leading edge direction.
The beneficial effects of the utility model are: the motor of the good heat dissipation of new structure, on the casing of motor He on front and rear covers, opened through hole, and added fan blade on rotor, the heat that motor when operation makes motor internal under the drive of fan blade by its discharge, overall structure is simple, easy to operate.
Brief description of the drawings
The structural representation of the rotor of the motor that accompanying drawing 1 is good heat dissipation of the present utility model;
The structural representation of the motor that accompanying drawing 2 is good heat dissipation of the present utility model.
Label declaration: 1-motor case; 2-front motor cover; 3-rotor; 4-fan blade; 5-snap ring; 6-motor rear cover.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 and accompanying drawing 2, the utility model shown in accompanying drawing provides a kind of motor of good heat dissipation, comprise motor case 1, front motor cover 2, motor rear cover 6 and rotor 3, on described rotor 3, be fixed with fan blade 4, between described motor housing, front motor cover 2 and motor rear cover 6, be provided with through hole 7, on described rotor 3, be also provided with snap ring 5, described snap ring 5 is arranged on fan blade 4 sides and limits fan blade 4 and moves axially, on described rotor 3, be provided with draw-in groove, the corresponding slot of described fan blade 4 installs and is equipped with the inserted block suitable with draw-in groove.
For the operating time phenomenon that overcomes temperature rise and extend motor, we have adopted on motor case 1, opened through hole 7 on front motor cover 2 and motor rear cover, and on rotor, added fan blade 4, while its objective is motor operation, can make the heat of motor internal be ejected under the drive of fan blade 4.Utilize jump ring to fix the axial endplay of fan blade 4, six inserted blocks of fan blade 4 insert the draw-in groove of rotor body, have avoided the radial rotary of fan blade 4.Like this in the time of machine operation, the wind energy of utilizing fan blade 4 to send, can make the Air Flow of motor internal, and the heat in motor is discharged by perforate.
In the present embodiment, the wheel hub that described fan blade 4 comprises blade and is connected with the output shaft of motor, described blade is being arranged on wheel hub of divergent shape, and the trailing edge of described blade offers serrated slot, and the degree of depth of described serrated slot is 5-10mm.
Whole blade be shaped as sickleshaped, according to becoming circular rector negative exponent flow pattern, high coefficient of lift combined design, blade external form is that sickle shaped is wide outside and narrow inside, three dimensions distorted shape, quantity is not done concrete restriction at the utility model, blade quantity in the present embodiment is 5, the trailing edge of blade is offered serrated slot, under equal air quantity, reduce fan noise, the maelstrom cutting that wind outlet is produced is carded to countless little eddy current, on the other hand, to viscous gas type effectively separate, guide effect, and finally become desirable air-flow.
On the other hand, due in the time that fan blade 4 rotates, more away from blade root, the air-flow of generation is larger, and the degree of depth of the serrated slot 13 therefore arranging is increased gradually by root to the degree of depth at top, and the air-flow of being convenient to producing is rolled into a ball more effective cutting; In the time that fan blade 4 rotates, less near the air-flow of blade root, separate by more shallow indentation cutting, larger away from the air-flow group of blade root, cut into little eddy current by darker indentation, realize large gap cutting speed air flow group.Low speed little airflow group is cut in little gap; By so dry straight the superior and the subordinate's air-flow of having avoided in conjunction with being that the eddyloss that the collision of air-flow causes occurs, thereby reach the object of noise reduction.
In the present embodiment, the angle of the sagittal plane of described blade and wheel hub rotation axis is 35 °, wherein between be controlled at ± 2 degree of the difference of internal diameter stagger angle.
In the present embodiment, on the lee face of described blade, be extended with groove from rectangular channel to leading edge direction, in the present embodiment, the quantity of groove is 3 roads, when blade rotary uses, air-flow can flow from blade groove, reduces the collision of air-flow at air intake surface and outlet air surface intersection.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
