Embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
In Fig. 1, Fig. 2, as the present invention preferred example, a kind of planetary reducer with heat dissipation ventilation function, including
Casing 1, ventilation unit and heat abstractor, ventilation unit are arranged at the upper surface of casing 1, and its junction is provided with one and is available for casing 1
The ventilating opening 2 of exhaust.Heat abstractor is connected with the ventilation unit, and ventilation unit is provided with some close to one end of ventilating opening 2
The gear oil clot 6 for preventing the fluid in the casing 1 from sputtering outward, in the present embodiment, gear oil clot 6 is three or four
It is individual, five etc., can prevent the fluid in outlet in casing 1 from being taken out of by air in casing 1.
Ventilation unit includes being available for the escape pipe 5 that gas is discharged in casing 1 and the air inlet pipe 7 for being available for ambient atmos to enter,
Escape pipe 5 is arranged on the surface of ventilating opening 2, and air inlet pipe 7 is arranged on the right side of ventilation unit, first is provided with escape pipe 5
Air check valve 3, the second air check valve 8 is provided with air inlet pipe 7.First air check valve 3 also includes being connected with elastic portion
The hollow out spheroid and block 4 of part, are provided with the induction installation that sensing hollow out spheroid contacts with block 4 in block 4, induction installation and
Heat abstractor electrically connects.When the temperature in casing 1 is too high to be needed to be vented and radiate, the air in casing 1 passes through the first air
Check valve 3 is discharged, and when the gas in casing 1 passes through the first check valve 3, gas up pushes away hollow out spheroid so that sphere takes off
From block 4, now, induction installation senses that sphere departs from block 4, and heat abstractor is communicated in a manner of electric signal so that
Heat abstractor works.
Heat abstractor includes tank for coolant 11, and tank for coolant 11 is connected with a coolant circulation being available in tank for coolant 11
The cooling tube 13 of flowing, one is additionally provided with tank for coolant 11 and transports the coolant of casing 1 to the coolant pump of cooling tube 13
12, cooling tube 13 is arranged in the casing 1.When heat abstractor is connected to the signal of induction installation, coolant pump 12 starts work
Make, the coolant in tank for coolant 11 is extracted into cooling tube 13, coolant flows in cooling tube 13, by the heat in casing 1
Amount is taken away, and eventually passes back to be cooled down again in tank for coolant 11, reaches hydronic purpose, improves the effect of cooling.
As shown in figure 1, as highly preferred embodiment of the present invention, escape pipe is curved to be turned under, and bent portion is rounding arc
Shape, the gas outlet of escape pipe 5 are down-set.The purpose so set is to prevent reductor from being worked in more dust atmospheres
When, extraneous dust can be entered in escape pipe 5 by gas outlet so that escape pipe 5 blocks, and causes exhaust to have some setbacks.Escape pipe 5
Outlet port be connected with casing 1, connect as one it, prevent from vibrating because the pipeline of escape pipe 5 is oversize in the course of the work,
So that casing is unstable.Same reason, the most preferably bending of air inlet pipe 7, bent portion are entering for rounding arcuation and air inlet pipe 7
Gas port is down-set.
Some water bloking pieces 9 are provided between air inlet and the second air check valve 8 in air inlet pipe 7, dash fast 9 is relative
Inwall is obliquely installed to air inlet, and when planetary reducer works in moister environment, air inlet block 9 can effectively be prevented
Only environmental liquids are entered in reductor by air admission hole, cause the damage of machine.The quantity of air inlet block 9 can also be four,
Any amounts such as five.
The screen pack 10 for stopping that external dust enters air inlet pipe 7 is provided with the air inlet of air inlet pipe 7, can effectively be prevented
Extraneous impurity dust is entered in casing 1 by air inlet pipe 7 during air inlet, influences part operating.
Cooling tube 13 is fixedly installed on the inwall of the casing 1, and is circumferentially laid along the inwall of casing 1.So set
The space accounting of cooling tube 13 can be greatly reduced, does not interfere with the transmission work inside planetary reducer, meanwhile, radiating surface
Product is big so that radiating effect is more preferable.
In gear oil clot 6 to tilt down setting, angle of inclination is 30 ° to 60 ° optimal, and the advantages of the setting that be relatively inclined upwardly exists
In when can prevent that planetary reducer usage time is long, fluid can converge in gear oil clot 6 and the formation of air-breather inwall
In angle, it is not easy to clear up.
Specifically, the operation principle of the present embodiment is：After planetary reducer work certain time, the temperature in casing 1
When too high, the air pressure in casing 1 is high compared with external atmosphere pressure, and gas can outward be discharged, generally, can often taken in gas
Fluid with sputtering, it is blocked by fluid during fluid catch 6, when gas is by the first air check valve 3, hollow out spheroid
Block 4 can be left, air can be discharged smoothly outward, meanwhile, the induction installation being arranged in block 4 senses that hollow out spheroid leaves
Block 4, control coolant pump 12 are worked, and coolant pump 12 is started working, and the coolant in tank for coolant 11 is extracted into cooling tube
In 13, coolant flows in cooling tube 13, and the heat in casing 1 is taken away, and eventually passes back to carry out in tank for coolant 11 cold again
But, reach hydronic purpose, improve the effect of cooling.When the air pressure in casing 1 is small compared with ambient pressure, outside air
It can be entered by air inlet pipe 7 in casing 1, during air inlet, by the effect of screen pack 10, introduced contaminants dust, water bloking piece 9 can be separated
The liquid in the external world can be stopped, prevent the part damaged in casing 1.
Advantage of this embodiment is that：Heat abstractor passes through the hydronic mode of cooling tube using coolant so that empty
Between accounting it is small, good heat dissipation effect；Using the ventilation unit of threeway, solves the problems, such as ventilation, while also prevent introduced contaminants
Enter the external world into the fluid in casing, casing, use is more convenient.Meanwhile controlled using ventilation unit by induction installation
The mode of heat abstractor so that the opportunity of radiating is more appropriate, will not cause the wasting of resources.
Only highly preferred embodiment of the present invention is described above, but is not to be construed as limiting the scope of the invention.This
Invention is not only limited to above example, and its concrete structure allows to change.All protection models in independent claims of the present invention
Interior made various change is enclosed to all fall in the scope of protection of the present invention.
