The utility model is set to further: described fork comprises the large end be connected with bent axle, and large end is made up of top and bottom, is connected by screw between described top and bottom.
By adopting technique scheme, fork makes split type structure, before screw lock, fork can be upwards freely movable at Crankshaft, after fork is automatically found the central position of cylinder, fixed by the bearing on fork and bent axle, reduce the installation difficulty of fork, make installation more accurate.
The utility model is set to further: described crankcase is provided with wind scooper, and described wind scooper is provided with bearing position, and on described bent axle, wherein one group of bearing is fixed on bearing position.
By adopting technique scheme, bent axle being arranged and can maple leaf be set, when crankshaft rotating; fan blade and bent axle are rotated simultaneously, pressure cooling is carried out to cylinder, oscillating bar assembly etc., reduces wear; improve the efficiency of compression, the setting of wind scooper is used for protecting fan blade.
The utility model is set to further: described crankshaft end is provided with belt pulley.
By adopting technique scheme, oscillating bar assembly is by belt transmission, and reduce noise during compression set work, transmission is stable.
Compared with prior art, the beneficial effects of the utility model are: adopt fork and leather cup structure; Swing rod structure can save piston, wrist pin, connecting rod, and connects the parts such as bearing of wrist pin and connecting rod, remarkable simplified structure; Leather cup is made by filling polytetrafluoro material, has good self lubricity and pliability, when compressing because gas pressure opens, being close to cylinder, effectively reducing leakage, raising the efficiency; Fork makes Split type structure, can be upwards freely movable at Crankshaft before locking, after fork is automatically found cylinder axis position, then fork and bent axle upper bearing (metal) is fixed; Adopt built-in fan blade simultaneously, force cooling cylinder and piston assembly, improve compression efficiency.This compression set is with of the same type without compared with outermost layer of skin band compressor, and structure is simple, reliable, and cost reduces, and stability improves, and install simple, service life of a machine also significantly improves.

Embodiment
Referring to figs. 1 through Fig. 4, the utility model three cylinder is described further without outermost layer of skin belt press embodiment.
A kind of three cylinders are without outermost layer of skin belt press, and comprise crankcase 1, be provided with three groups of oscillating bar assemblies on the upside of crankcase 1 at an angle, crankcase 1 is provided with the cylinder 3 supporting with oscillating bar assembly, valve plate 31 and cylinder cap 32 and forms.Cylinder 3, valve plate 31 and cylinder cap 32 are all be fixed on crankcase 1.The large end of fork 4 is by top 41, bottom 42, leather cup 43, and the leather cup gland 44 of fixing leather cup 43 forms, the top 41 of fork 4 and bottom 42 combine, when screw 45 is not locked by screw 45, the installation circular hole of bottom fork 4 and fork 4 top 41 composition can become large a little, convenient installation; Oscillating bar assembly is constrained in cylinder 3 respectively, axially can only do up and down reciprocatingly swing along cylinder 3.Crankcase 1 substantially horizontal is installed with 5, bent axle, arrange in crankcase 1 and 5, bent axle and bearing 6 and bearing 7 are installed, by bearing 6 and bearing 7, bent axle 5 is fixed, make each point on bent axle 5 stressed more even, reduce the vibrations produced in bent axle 5 rotary course; Belt pulley 2 is equipped with in bent axle 5 outer end; Belt pulley 2 and bent axle 5 can rotate under the driving of external force in 5, bent axle, adopt belt transmission, stable drive, reduce vibrations; The eccentric shaft of bent axle 5 is equipped with three cover bearings, bearing connects oscillating bar assembly major part respectively; Bent axle 5 end face is provided with fan blade 8, and fan blade 8 with bent axle 5 synchronous axial system, by cooling air swing link guide assembly and cylinder 3, can force cooling oscillating bar assembly and cylinder 3.
Before screw 45 not locking, the large end of oscillating bar assembly can move left and right along the eccentric shaft of bent axle 5, to ensure that the center of oscillating bar assembly can aim at the center of cylinder 3 automatically, avoids because personal factor causes installation deviation; After oscillating bar assembly aims at the center of cylinder 3 automatically, then the screw 45 on oscillating bar assembly is locked respectively.Wind scooper 9 is provided with the bearing position 91 installing bearing 6, supports bent axle 5.
When belt pulley 2 driving crank 5 rotates; Eccentric shaft on bent axle 5 drives oscillating bar assembly in cylinder 3, do the to-and-fro motion not needing lubricant oil, achieves the air-breathing needed for compression and exhaust process; The friction of oscillating bar assembly between cylinder 3 is realized by the leather cup 43 of selflubricating; Leather cup 43 is made up of filling polytetrafluoro material, has good self lubricity and pliability, when compressing because gas pressure opens, being close to cylinder 3, effectively reducing leakage, raising the efficiency; Fan blade 8 rotates the air-flow formed and is directed to cylinder 3, forces cooling cylinder 3 and oscillating bar assembly, effectively reduces the temperature of cylinder 3 and oscillating bar assembly, improve compression efficiency.
The utility model is with of the same type without compared with outermost layer of skin band compressor, and its structure is simple, reliable, and cost is low, and stability is high, and install simple, service life of a machine also significantly improves.
