Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments, not
In the case of conflict, the features in the embodiments and the embodiments of the present application can be combined with each other, and below with reference to the accompanying drawings and tie
Conjunction embodiment is next, and the present invention will be described in detail.
Non-lubricated vortex compressor of the present invention is as shown in Figure 1, 2：Including fixed scroll 1 and orbiter 2, fixed scroll
1 and orbiter 2 installed at 180 degree is opposite, the scroll wrap of fixed scroll 1 and orbiter 2 is all single vortex toothing, quiet whirlpool
The opposing face of the scroll wrap of capstan 1 and orbiter 2 is distributed with cooling fin, and specifically, cooling fin is evenly distributed on described quiet
On the opposing face of scroll plate 1 and the scroll wrap of the orbiter 2, in the present embodiment, cooling fin is copper aluminum composite material one
It is made, to improve heat dissipation effect, specifically, the cooling fin is that copper aluminum composite material uses cold forging or warm forging technique one landform
At on the opposing face of the scroll wrap of fixed scroll 1 and the orbiter 2, and cold forging or the technological temperature of warm forging are -10 DEG C
~500 DEG C, pressure be 500 to 1000MPa, preferably, temperature is 200 DEG C, pressure 800MPa.
The back side of fixed scroll 1 sets that there are one the cooling fins of end plate and fixed scroll 1 to constitute a gas channel, dynamic
The back side of scroll plate 2 is set there are one pallet, and a gas channel, fixed scroll 1 are also formed with the cooling fin of orbiter 2
Self-lubricating solid friction pair 3, self-lubricating solid friction pair 3 are installed additional with the tooth top of the scroll wrap of orbiter 2.
It please refers to shown in Fig. 3, the small crank throw 4 of rotate-stationary mode is installed on pallet, small crank throw 4 prevents orbiter 2 certainly
Turn, small crank throw 4 is equipped with self lubricating and seals bearing, and fixed scroll 1 is bolted on stake body 6, and orbiter 2 exists
Plane motion is done between fixed scroll 1 and stake body 6,2 center of orbiter connects main shaft 8, drive of the orbiter 2 in main shaft 8
It is rotated under dynamic, wind wheel 7 is installed on the main shaft 8, specifically, disk 10 is installed on main shaft 8, disk 10 is fixed with wind wheel 7
Together, fan housing 5 is cased with outside wind wheel 7, fan housing 5, wind wheel 7 and main shaft 8 form gas channel, and wind wheel 7 is under the drive of main shaft 8
Rotation is taken away the heat that the operation of fixed scroll 1, orbiter 2 and main shaft 8 generates, to reduce complete machine temperature.Self-lubricating rubs
It is polyether-ether-ketone (PEEK) based composites to wipe the self-lubricating material that pair 3 uses.The small crank throw 4 includes bent axle 401 and 402,
Small crank throw 4 is cylinder, and small crank throw 401 and 402 both ends are equipped with self-lubricating seal bearing, the both ends point of small crankshaft 401 and 402
It An Zhuan not be on pallet and stake body.
The present invention forms anti-rotation mechanism using small crank throw 4, and the small crank throw 4 in this way in anti-rotation mechanism only rotates
Formula, and without reciprocating, thus oil-free lubrication easy to implement；In addition all bearings in apparatus of the present invention are all self-lubricating bearing,
Solid Self-lubricant Bearing or sealed bearing, without extraneous oil lubrication, it can be achieved that oil-free lubrication, preferably
Meet the non-lubricated vortex compressor of big capacity needed for fuel battery engines, small appearance and size.The present invention realizes
The cleaning compression of gas, can apply the fuel battery engines occasion more demanding to compressor；And it is simple in structure, it is easy real
It is existing；The heat that gas compression generates can easily shed.The loss of low friction pair can be largely dropped, and can realize compression
The oil-free lubrication of intracavitary and quickly reduction scroll plate temperature.To meet requirement of the food medicine and other fields to compressor.
Compared with previous oil lubrication screw compressor, main advantages of the present invention are：1) use oil-free lubrication that can save
Deoil lubricating circulatory system and gs-oil separator；2) after using small crank throw anti-rotation mechanism, orbiter 2, stake body 6 and Chinese yeast
Turn 4 relative motion becomes rotary motion from the reciprocating motion of original crosshead shoe, crosshead shoe can only be relied on accurate
It processes and realizes smaller friction with self-lubricating material, this means that higher production cost, while also comparing and being difficult to ensure,
And the forms of motion of small crank throw rotation-preventing mechanism is only rotary motion, the small crank throw 4 of rotary motion is when using self-lubricating composite
Or sealed bearing, it is easy to realize oil-free lubrication, and rotary motion greatly reduces the secondary abrasion of friction；Small crank throw is anti-simultaneously
Inertia force caused by rotation mechanism can be also fully balanced, the motor pattern of small crank throw 4 and the complete phase of motor pattern of main shaft 8
Together, small crank throw 4 can also share the centrifugal intertia force of part orbiter 2, improve the inertia force distribution of orbiter 2, be conducive to
Extend the service life of main shaft 8, increase the stationarity of 2 stress of orbiter.3) in fixed scroll 1 and orbiter 2 and stake body 6
Structure design, in having the screw compressor of oil lubrication in the past, between dynamic and static scroll plate between dynamic vortex and stake body 6 according to
Sliding relative movement is realized by oil lubrication；Since the orbiting and fixed scroll and stake body are not self-lubricating materials, the present invention
Increase self-lubricating solid friction pair 3 at opposite sliding, be mounted with self-lubricating material, select tool with compared with low-friction coefficient and compared with
Self-lubricating material polyether-ether-ketone (PEEK) based composites of high wear resistance realize tooth top sealing friction pair, are replaced with this
For oil lubrication, this self-lubricating material is that can guarantee being smoothed out for opposite sliding, and can guarantee to by the sealing of compressed gas.
It can equally ensure that there is smaller friction power loss and the smaller wear of work, not generate excessively high Wen Sheng, will not cause excessive
Vibration and noise.4) realize that heat dissipation, main shaft 8 drive the rotation of wind wheel 7 to generate air-flow, gas by installing wind wheel 7 additional on main shaft 8
Stream is by the heat dissipation channel between the heat dissipation channel and orbiter 2 and stake body 6 of fixed scroll 1, to take away due to compression
And the heat generated, delivery temperature and complete machine temperature are reduced, ensure that the performance safety of complete machine.
The above is only the better embodiment to the present invention, not makees limit in any form to the present invention
System, every any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
