As shown in Figure 9, rotor 2, the first fan blade 3, the 4th fan blade, the first bent axle 5, the second bent axle 26 are arranged on the first crankcase 4 and the second crankcase 33 and can be freely rotated by bearing, be positioned at two groups of piston assemblys of the rotor left and right sides, be placed on respectively in two groups of coaxial opposed cylinders (the first cylinder 6 and the second cylinder 18, the 3rd cylinder 19 and four-cylinder 32), cylinder is fixed on the first crankcase 4 and the second crankcase 33, and piston assembly can do along the vertical direction free to-and-fro motion in cylinder.By the large bearing with lubricating grease on connecting rod, two cover piston assemblys are arranged on respectively on the first bent axle 5, the second bent axle 26, the first bent axle 5, the second bent axle 26 can directly be realized circumferential relative movement with connnecting rod big end by the large bearing with lubricating grease, piston assembly can, under the driving of the first bent axle 5 of bias, the second bent axle 26, be realized regular pumping.
The first bent axle 5, the second fan blade 12 is housed on the second bent axle 26 successively, the 3rd fan blade 27, the first wind scooper 13 and the second wind scooper 28, the first wind scooper 13 and the second wind scooper 28 are fixed, the second fan blade 12, the 3rd fan blade 27 can synchronously rotate with rotor shaft, the second fan blade 12, the 3rd fan blade 27 forms cooling air while rotation, the first wind scooper 13 and the second wind scooper 28 are by wind lead two groups of piston assemblys and the first cylinder 6, the second cylinder 18, on the 3rd cylinder 19 and four-cylinder 32, the first cylinder 6, the second cylinder 18, axial cooling fin on the 3rd cylinder 19 and four-cylinder 32 can be by further wind pilot valve group, cooling valve group 36, valve group is fixedly mounted on cylinder.
As shown in Figure 11,15, valve group 36 and cylinder cap 38 are fixedly equipped with in cylinder top, between cylinder and valve group, O RunddichtringO 35 are set, and valve group seal ring 37 is set between valve group and cylinder cap, have improved reliability; Simultaneously because cylinder, valve group 36 and cylinder cap 38 can contact by direct metal, overall thermal conductivity improves, heat in cylinder cap 38 and valve group 36 can be transmitted on cylinder (the first cylinder 6, the second cylinder 18, the 3rd cylinder 19 and four-cylinder 32) and crankcase (the first crankcase 4 and the second crankcase 33) fast, by cold wind, heat is taken away, reduced the operating temperature of machine.
As shown in Figure 10-11, the air filter 34 with noise elimination function is housed on the suction port of cylinder cap 38 of the present invention, can effectively reduce the noise of machine.As shown in Figure 13-14, air filter 34 is by base 34a, and filter core 34c and lid 34b form, and base 34a has 2 cavitys, and large cavity is plugged with sponge filter core 34c, and little cavity packs band into and leads the lid 34b of mouth; The noise that machine produces, by entering little cavity after large cavity refraction, then discharges from leading mouth of lid 34b again; Noise can significantly reduce.
As shown in Figure 1, because rotor left side structure is identical with right side structure, therefore parts (the 3rd cylinder 19 in left side, the 3rd leather cup gland 20, the three piston cup 21, the three guide rings 22, the second piston 23, the second wrist pins 24, second connecting rod 25, the second bent axle 26, the three fan blade 27, the second wind scoopers 28, the 4th guide ring 29, the four piston skin 30, the four leather cup glands 31, four-cylinder 32, the second crankcases 33) and annexation be not described in detail at this.
In the time that rotor moves, bent axle drives two cover piston assemblys to pump respectively by connecting rod, guide ring plays effect of contraction, the relative movement of bent axle and connecting rod is by completing containing fat bearing (with the large bearing of lubricating grease), rolling pendulum motion between connecting rod and wrist pin is by completing containing fat bearing (with the little bearing of lubricating grease), reciprocating friction motion between piston assembly and cylinder is lubricated by piston cup and the guide ring of selflubricating, two double-head pistons do the to-and-fro motion that does not need lubricant oil in cylinder, have realized and have compressed required air-breathing and exhaust process.Piston cup opens in compression process, by gas compression and discharge cylinder; In breathing process, piston cup is regained, and reduces the friction of itself and cylinder wall surface.Due to the line of centres X of two the first bent axles 5, the second bent axle 26
5with X
26angle 90 degree that stagger, in rotary course, the cycle of each piston arrives top dead center also will stagger for 1/4 cycle like this, thus the compression process in 4 compression chambers is 1/4 cycle of mutually staggering; Taking Fig. 1 as example, in 1/4 cycle of beginning, A chamber completes compression; In 1/4 to 1/2 cycle, C chamber completes compression; In 1/2 to 3/4 cycle, B chamber completes compression; 3/4 to end cycle, and D chamber completes compression.The benefit of even compression is like this to have avoided the moment of torsion of drive motor to concentrate, and makes drive motor moment of torsion in the whole operation cycle even, and efficiency improves; Make pressurized gas physical efficiency produce uniformly and discharge simultaneously, reduced the intensity that valve group and other pressure-containing member are hit, thereby improved service life of a machine of the present invention.The air-flow that fan blade rotates to form is by 4 cylinders of wind scooper guiding and piston assembly, then by cylinder axial cooling fin pilot valve group and cylinder cap bottom, forces cooling cylinder, piston assembly, valve group and cylinder cap, reduced machine operating temperature, improved compression efficiency.And the air-flow that fan blade rotates to form in inside quick cooling stator and rotor, heat is taken out of, reduced the temperature rise of drive motor, improved the life-span of drive motor.
The present invention is compared with compressor of the same type, and mentality of designing fashion, has changed traditional oil lubrication that has and compressed lubricating system; Novel structure, the double-head piston of tape guide ring and piston cup, the bent axle that dislocation 90 degree are settled, 2 groups of opposed cylinders, can output pure pressurized air uniformly; Its reliable in structure, compactness, cost is low, and efficiency is high, leaks lowly, and the life-span is high, good stability.
