Description
Technical field
The utility model relates to a kind of heat radiation framework of closed toolroom machine, particularly relates to a kind ofly driving air current flow when rotating by motor rotor and reaching the toolroom machine heat radiation framework of heat radiation function.
Background technology
Since the invention of electro-motor begins, since several centuries constantly progress and development for the mankind bring great facility in life, Large Electric motor by initial industrial use, until the less electric household motor of volume, be applied to small-sized electric motors such as daily living article, toolroom machine at last, its volume is more and more littler along with improvement and the innovation of structure, manufactured materials, applicable aspect also more and more wider.
Electro-motor can be told multiple variety classes motor according to tectonic province now, every kind of motor all has different operating characteristic, no matter be features such as volume, heat radiation, torsion, rotating speed, material, manufacturing cost, control mode, all be not quite similar for every kind of electro-motor, can't directly conclude which kind of electro-motor structure for best, must consider that on the contrary the environment of use, demand could select optimal electro-motor.Yet for general more small-sized electro-motor, the most harsh service condition and environment are no more than the electro-motor in the toolroom machine.
Be applied to the electro-motor in the toolroom machine; can test all characteristics of electro-motor easily; for example can want usually that cube is little, the torsion foot, speed demand is high and most important durability under long-time use; as long as above-mentioned a certain characteristic performance has defective, will cause the toolroom machine can't operation or damage easily.The part that wherein more easily causes puzzlement mainly is that electro-motor inside is produced by coil (Coil) on bearing (Bearing), the motor stator (Stator) and electromagnetism (Electromagnetism) and the heat accumulated, because heat causes electro-motor overheated, could operate for a long time and directly influence toolroom machine, just influence the durability of toolroom machine.
The general common electro-motor that is used for toolroom machine all uses the d.c. motor (Brushed DC Motor) that has brush (Brush) and commutator (Commutator), yet this kind motor volume is big, efficient is low, and the spark that is produced between brush and the commutator all can cause consume and be considered as the regularly consumers of replacing this two elements.Therefore the toolroom machine motor DC Brushless Motor that volume is less, efficient is higher (Brushless DC Motor) of using instead gradually is applied on the toolroom machine, but make that because volume is less the heat that motor produced is more concentrated, and be applied to DC Brushless Motor in the toolroom machine more because be coated in the more airtight housing, can't get rid of long-pending heat easily, temperature is too high when causing use easily, cause motor overheated (Over Heat) and influence the running of toolroom machine, therefore many radiator structure consequentialities are arranged.For example United States Patent (USP) the 6th, 789, No. 630, the 7th, 166, shown in No. 939, No. the 2008/0233848th, U.S. Patent Publication, TaiWan, China patent announcement M263204 number, for using in the DC Brushless Motor toolroom machine inner rotor motor (the Inner Runner Motor) structure of the most normal use, its main radiating mode usually at axle center (Shaft) but on be equiped with the flabellum (Fan) or the fin (Heat Sink) of interlock, interlock flabellum or fin together rotate in the time of by main revolution, and then cause that air current flow reaches the heat radiation purpose on motor.In addition, a kind of heat radiation motor that another group has flabellum that is provided with is arranged more also, no matter whether main motor rotates, and all can utilize the heat radiation motor to continue to dispel the heat.Yet, the effect of aforesaid way in toolroom machine long-time use as the same limited down, and and increased many volumes and part outward, also increased manufacturing cost and power consumption simultaneously; And the external-rotor motor of less use (Out Runner Motor) structure in the DC Brushless Motor toolroom machine has the problem that is difficult to dispel the heat as inner rotor motor structure equally.Therefore the heat-dissipating structure of corresponding outer-rotor structure is also arranged shown in TaiWan, China patent announcement M269645 number, mainly on external rotor, offer air admission hole, and on housing, also offer corresponding open-work, the inspiration air-flow by external rotor rotates, discharge air-flow by the open-work on the housing, reaching the purpose of heat radiation by this.Yet the radiator structure of this kind external rotor DC Brushless Motor only depends on the air admission hole scarf on the external rotor to promote for the disturbance of air-flow, and is also limited in the long-pending heat that long use is got rid of down.Hence one can see that, is applied to the space that DC Brushless Motor in the toolroom machine also has many progress, to improve the bad disappearance of being brought of heat radiation.
This shows that the heat radiation framework of above-mentioned existing closed toolroom machine obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of heat radiation framework of closed toolroom machine of new structure, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
