Abstract
The invention discloses a forced air cooling structure of a rod-shaped linear motor. An air gap is formed between an inner-side annular surface of a tubular rotor piece and a rod-shaped stator piece. An air inlet joint is communicated with an external high-pressure gas source, such that gas of the external high-pressure gas source can be led into the air gap through air channels. By means of mutual communication of the air channels and connection channels of a flow leading portion, and with each air channel tilted by a certain angle, it can be ensured that the airflow of the high-pressure gas source mainly flows into the air gap, and therefore, it can be ensured that the external low-temperature gas can continuously enters the air gap, and a favorable cooling effect can be ensured.
Description
Technical field
The present invention is relevant with bar-shaped motor, particularly about a kind of forced air-cooling of bar-shaped linear motor, constructs.
Background technology
At present, with regard to known bar-shaped motor, it is to take the bar-shaped stator of a suitable length to be basis substantially, one mover in a tubular form is coaxially set on this stator, make the changes of magnetic field that can give birth to by this mover Inside coil and the magnetic field reciprocation on this stator, and then order about this mover along the axial reciprocating displacement start of this stator.
And because the variation of mover internal magnetic field is to cause by importing electric current, and electric energy is also accompanied by the generation of heat energy when coil produces magnetic field, be with, for heat energy is able to by suitably dissipation, avoid affecting the work doing efficiency of motor, before TaiWan, China M318487 new patent, in case, just disclose the cooling mechanism that has a kind of bar-shaped motor, it is the passage that the air gap between mover and stator is gas flow, and the axis hole that makes mover both ends is the inclined hole of pushing and drawing shape, in mover two ends, form according to this headroom that enters extending out, thereby when mover slides on stator, slip by mover enters in air gap outside air, in order to reach the effect of heat radiation.
Before above-mentioned new patent, case is by the axis hole shape extending out, admittedly can improve the flow that extraneous gas enters air gap, but because the mobile of its gas is that the slippage that sees through passively mover produces, therefore, when the translational speed of mover is slower, flowing of gas also slows down simultaneously, makes the effect of heat radiation still not attain ideal, and has in addition improved necessity.
Summary of the invention
Main order of the present invention is to provide a kind of forced air-cooling structure of bar-shaped linear motor, it is by the gas of being supplied by external air source, import in the inter-air space between mover and stator, pressure by source of the gas, make gas in this inter-air space, continue to flow, the impact that not whether moved by mover, so as to obtaining preferably heat radiation function.
To achieve these goals, the present invention is by the following technical solutions:
A kind of forced air-cooling structure of bar-shaped linear motor, is characterized in that, it includes:
Bar-shaped stator elements always;
One tubulose mover part, is to be coaxially slidedly arranged in this stator elements, and can be along the axial reciprocating linear displacement of this stator elements;
One ring-type air gap is between between all side ring surfaces of this mover part inside tube face and this stator elements;
At least one diversion division, has at least one poroid air flue, is to be located on this mover part and with this air gap to be communicated with that an inlet suction port is to be communicated with external high pressure source of the gas, in order to the gas of this external high pressure source of the gas is imported in this air gap via this air flue.
Described mover part is to have two ends, and plurality of coils is to be located between this two end, and this diversion division is located on the end of a correspondence.
The hole axle of described air flue is and the tubular axis of this mover part acute angle angle of being separated by.
The air flue quantity that described diversion division has is to be majority, and is communicated with this air gap respectively, and this diversion division also includes most poroid connections road, is to be communicated with respectively respectively this air flue, and makes respectively this air flue communicate with each other via this connection road respectively.
Described inlet suction port is that the connection road of a correspondence coaxially communicates.
The invention has the beneficial effects as follows: by the composition of above-mentioned member, thereby reach desirable heat radiation function.And the footpath difference of the present invention by this cooling inner and outer pipe is respectively to form the concrete technology contents of this radiating flow passage, to have more the concrete effect that is easy to assembling processing, and cooling effectiveness is also better.

Embodiment
Below only with embodiment, the enforcement aspect that the present invention is possible is described, however not in order to limit the category of institute of the present invention wish protection, first give chat bright.
Below, lift with a preferred embodiment of the present invention, and coordinate graphic being described further.
Refer to shown in each figure, in a preferred embodiment of the present invention, the forced air-cooling of the bar-shaped linear motor that provides structure 10, its be mainly comprised have a stator elements (not showing on figure), a mover part 20, an air gap 30 and two diversion divisions 40.
And wherein, about the technology contents of this stator elements, this mover part 20 and this air gap 30, be the bar-shaped linear motor technology content that belongs to known, by and large:
The vertical bar that this stator elements is is bar-shaped, be with most magnet is located in always in body formed, make to form fixing magnetic field by this magnet respectively;
20 of this mover parts are in a tubular form, and wear coaxially, be slidedly arranged in this stator elements, and there are two apart coming and coaxial corresponding annular block end 21,22 of most annuluses are between this two end 21, one 23, mover shell is located on the respectively outside of this coil 22, and bridge joint is fixedly arranged on this two end 21;
30 of this air gaps are the annuluses between between these mover part 20 inside tube faces and all side ring surfaces of this stator elements.
Respectively this diversion division 40 is to be divided on this two end 21, and be communicated with outside high-pressure air source separately, in order to the gas of being supplied by external high pressure source of the gas is imported in this air gap, to form, continue mobile air-flow, reach cooling effect, furthermore, respectively this diversion division 40 is to have respectively most poroid air flues 41, to be located at respectively on corresponding end 21, and the be separated by angle [alpha] of an acute angle of the tubular axis that makes hole axle and this mover part 20, and be communicated with this air gap 30 separately, most poroid connection roads 42 are to be also located in this end 21, and contact each other and be communicated with respectively this air flue 41, make according to this respectively this air flue 41 must be via this connection road 42 respectively and communicate with each other, one inlet suction port 43 is that the connection road 42 corresponding with coaxially communicates, and can be connected with external high pressure source of the gas by exterior line, gas is imported to other via worn connection road 42 to be connected in road 42, and disperse to enter in this air gap 30 via this air flue 41 respectively, to form suitable air-flow equably in each position of annular of this air gap 30.
