Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Non-lubricated vortex compressor of the present invention comprises fixed scroll 1 and orbiter 2 as shown in Figure 1, fixed scroll 1 is mounted opposite with orbiter 2 one-tenth 180 degree, the scroll wrap of fixed scroll 1 and orbiter 2 is all single scroll wrap structure, the opposing face of the scroll wrap of fixed scroll 1 and orbiter 2 is distributed with radiating fin, the radiating fin that the back side of fixed scroll 1 is provided with an end plate and fixed scroll 1 constitutes an air-flow path, a pallet is provided with at the back side of orbiter 2, also an air-flow path is just defined with the radiating fin of orbiter 2, the tooth top of the scroll wrap of fixed scroll 1 and orbiter 2 installs self-lubricating solid friction pair 3 additional, self-lubricating solid friction pair 3 as shown in Figure 2, pallet is provided with the little crank throw 4 of rotate-stationary mode, little crank throw as shown in Figure 3, little crank throw 4 prevents orbiter 2 rotation, little crank throw 4 is provided with self lubricating stuffing box bearing, fixed scroll 1 is bolted on stake body 5, orbiter 2 does plane motion between fixed scroll 1 and stake body 5, orbiter 2 center connects main shaft 6, orbiter 2 rotates under the driving of main shaft 6, main shaft 6 is provided with wind wheel 7, wind wheel 7 outer cover has fan housing 8, fan housing 8 forms air-flow path with wind wheel 7 and main shaft 6, air-flow path as shown in Figure 4, the direction of arrow is airflow direction, wind wheel 7 connects belt pulley 9, wind wheel 7 rotates under the drive of belt pulley 9, by fixed scroll 1, orbiter 2 and main shaft 6 run the heat produced and take away, thus reduction complete machine temperature.The self lubricating material that selflubricating friction pair 3 adopts is polyether-ether-ketone (PEEK) based composites.Little crank throw 4 comprises the first bent axle 401 and the second bent axle 402, first bent axle 401 is arranged on pallet by self lubricating stuffing box bearing, and the second bent axle 402 is arranged on stake body 5 by self lubricating stuffing box bearing.Fig. 5 is stereoscopic figure of the present invention.
The present invention adopts little crank throw 4 to form anti-rotation mechanism, and the little crank throw 4 like this in anti-rotation mechanism only has rotary, and without reciprocating, thus easily realizes oil-free lubrication; In addition all bearings in apparatus of the present invention are all self oiling bearing, or Solid Self-lubricant Bearing, or sealed bearing, without the need to extraneous oil lubrication, can oil-free lubrication be realized, meet the non-lubricated vortex compressor of the large air displacement needed for fuel battery engines, little boundary dimension preferably.Present invention achieves the clean compression of gas, the fuel battery engines occasion higher to compressor requirement can be applied; And structure is simple, easily realizes; The heat that gas compression produces can easily shed.The loss of friction pair can be reduced largely, and the oil-free lubrication that can realize in compression chamber and fast reduce scroll temperature.To meet the requirement of food medicine and other fields to compressor.
Compared with oil lubrication scroll compressor in the past, major advantage of the present invention is:
1) oil-free lubrication is adopted can to save the oil lubrication circulatory system and deaerator.
2) after adopting little crank throw anti-rotation mechanism, orbiter 2, the relative movement of stake body 5 and little crank throw 4 becomes rotary motion from the to-and-fro motion of original crosshead shoe, accurate processing and self lubricating material can only be relied on to realize less friction for crosshead shoe, this just means higher cost of production, also compare simultaneously and be difficult to ensure, and the forms of motion of little crank throw rotation-preventing mechanism is only rotary motion, the little crank throw 4 of rotary motion is when adopting self-lubricating composite or sealed bearing, be easy to realize oil-free lubrication, and rotary motion greatly reduces the wearing and tearing of friction pair, the inertial force that little crank throw rotation-preventing mechanism brings simultaneously also can be fully balanced, the motor pattern of little crank throw 4 is identical with the motor pattern of main shaft 6, small crankshaft 4 and main shaft 6 have the identical turning radius, when main shaft 6 rotates under motor drives, first bent axle 401 and the second bent axle 402 also keep synchronous rotary motion, thus realize the plane motion of orbiter 2, prevent the spinning motion of orbiter 2 simultaneously.Little crank throw 4 also can share the centrifugal inertia force of part orbiter 2, improves the inertial force distribution of orbiter 2, is conducive to the life-span of prolongation main shaft 6, increases the stressed stationarity of orbiter 2.
3) in the structural design of fixed scroll 1 and orbiter 2 and stake body 5, having in the scroll compressor of oil lubrication in the past, and between dynamic and static scroll and between dynamic vortex and stake body 5, relying on oil lubrication to realize sliding relative movement; Because the orbiting and fixed scroll and stake body are not self lubricating materials, the present invention adds self-lubricating solid friction pair 3 at relative sliding place, self lubricating material has been installed, tool is selected to realize tooth top sealing friction pair with compared with low coefficient of friction with compared with self lubricating material polyether-ether-ketone (PEEK) based composites of high wear resistance performance, alternative oil lubrication is carried out with this, this self lubricating material can ensure carrying out smoothly of relative sliding, can ensure again by the sealing of pressurized gas.Can ensure that there is less friction power loss and the less wear of work equally, not produce too high temperature rise, excessive vibration & noise can not be caused.
4) heat radiation is realized by installing wind wheel 7 on main shaft 6 additional, main shaft 6 drives wind wheel 7 to rotate and produces air-flow, air-flow is through the heat dissipation channel of fixed scroll 1 and the heat dissipation channel between orbiter 2 and stake body 5, thus take away the heat produced due to compression, reduce delivery temperature and complete machine temperature, ensure that the performance safety of complete machine.
The above is only to better embodiment of the present invention, not any pro forma restriction is done to the present invention, every any simple modification done above mode of execution according to technical spirit of the present invention, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
