But its current Problems existing is, serious wear and not easily changing, all there is this kind of problem in similar structure.
Model utility content
The object of model utility: in order to provide a kind of Novel compressor crankshaft structure of better effects if, specific purposes are shown in multiple substantial technological effects of concrete implementation section.
In order to reach as above object, the utility model takes following technological scheme:
A kind of new type of compression crankshaft structure, it is characterized in that, comprise rotating shaft, described rotating shaft comprises two eccentric wheels along with the direction that it extends, two eccentric wheels comprise a coupling shaft respectively, this coupling shaft and rotating shaft decentraction, also comprise the porose connecting rod in end one and connecting rod two, described connecting rod one and the respective borehole jack of connecting rod two are on two eccentric coupling shafts, described connecting rod one and connecting rod two Hinged piston bar separately, the each self energy of described piston rod is twitched and is driven Pistons's piston hole inside to compress in piston hole, described rotating shaft 1 comprises an oil sealing space, it is around rotating shaft and there is lubricant oil inside.
The further technological scheme of the utility model is, described rotating shaft comprises hole, two each self-contained balance of eccentric wheel, lubricant oil is equipped with in its inside of balance, eccentric wheel there is equalizing orifice, equalizing orifice is connected to attachment hole, eccentric wheel running time, lubricant grease can along attachment hole contact bearing lubricating bearings.
The further technological scheme of model utility is, described eccentric wheel comprises equalizing orifice, and there is lubricant oil its inside, and lubricant oil can ooze out from hole.
Adopt the utility model of as above technological scheme, there is following beneficial effect relative to prior art: add oil sealing, so just can reduce oil loss, reduce connecting rod inner bearing and eccentric wearing and tearing further, longer service life, product running more steadily not easily produces vibrations.
Accompanying drawing explanation
In order to further illustrate the utility model, be described further below in conjunction with accompanying drawing:
Fig. 1 is model utility structural representation;
Fig. 2 is one of implementation structure of being connected with piston of the connecting rod of model utility;
The structure shown in Fig. 3 is the another kind of form of bent axle;
Wherein: 1. rotating shaft; 2. connecting rod one; 3. connecting rod two; 4. eccentric wheel two; 5. eccentric wheel one; 6. piston rod; 7. piston hole; 8. oil sealing space; 9. equalizing orifice; 10. attachment hole.
Embodiment
Be described embodiment of the present utility model below in conjunction with accompanying drawing, embodiment does not form restriction of the present utility model:
A kind of new type of compression crankshaft structure, it is characterized in that, comprise rotating shaft 1, described rotating shaft 1 comprises two eccentric wheels along with the direction that it extends, two eccentric wheels comprise a coupling shaft respectively, this coupling shaft and rotating shaft 1 decentraction, also comprise the porose connecting rod in end 1 and connecting rod 23, described connecting rod 1 and the respective borehole jack of connecting rod 23 are on two eccentric coupling shafts, described connecting rod 1 and connecting rod 23 Hinged piston bar 6 separately, the each self energy of described piston rod 6 is twitched and is driven Pistons's piston hole inside to compress in piston hole 7, described rotating shaft 1 comprises an oil sealing space 8, it is around rotating shaft and there is lubricant oil inside.The technique effect of the essence that the technological scheme at this place plays and implementation procedure thereof are as follows: add oil sealing, so just can reduce oil loss, and reduce the wearing and tearing of rotating shaft and eccentric wheel position further, longer service life, product also not easily shakes.Oil sealing space be formed with various ways, the oil sealing space that is expressed as shown in Figure 1 is the enclosed space that cyclic structure is formed, and it is enclosed within axle, also can add gambling sheet formation seal space by it.
Through contrast, under same rotational strength, this kind adds equalizing orifice and deposits oil-bearing structure, is about more than 2500 hours working life, and does not have the structure of oil sealing, and working life is less than 1500 hours, have even lower than 500 hours.
Described rotating shaft comprises hole, two each self-contained balance of eccentric wheel, lubricant oil is equipped with in its inside of balance, eccentric wheel there is equalizing orifice, equalizing orifice is connected to attachment hole, when eccentric wheel running, lubricant grease can the technique effect of the essence that the technological scheme at this place of lubricating bearings plays and implementation procedure thereof be as follows along attachment hole contact bearing: ooze out the grease come, can conveniently lubricate, can lubricate on rotation limit, limit, while preventing lubricant oil from blocking mechanical movement, also play the effect of slow releasing lubricant oil, in addition, if pore size distribution is even, then can also play the effect of evenly release lubricant oil.
In a creative way, each effect above independently exists, and can also complete the combination of the above results with a nested structure.
It is clear that the technique effect that above structure realizes realizes, if do not consider the technological scheme of adding, this patent title can also be a kind of bent axle, and it is not limited to this equipment for Germany.
Not shown in the figuresly to portal.The structure shown in Fig. 3 is the another kind of form of bent axle, as further implementation structure, described bent axle comprises the symmetrical eccentric wheel of two one-tenth 180 ° with its bearing of trend, and two eccentric wheels are connected with second piston (high pressure) with first stage piston (low pressure) with connecting rod two respectively by connecting rod one.Crankshaft operation makes piston to-and-fro motion pressurized gas in respective cylinder, carries out suction and discharge.Eccentric wheel respectively comprises an equalizing orifice, and there is lubricant grease inside, does not have lubricant oil in oil-free compressor crankcase, needle roller bearing without inner ring is only had to carry limited grease, eccentric wheel operates, and easily throws away bearing grease and bearing dry friction is operated, greatly reduce working life.
And if eccentric wheel run both sides add jam, formed closed chamber, concrete formation condition is, because crankshaft installed is at machine internal, lubricant oil external channel only has one, can block formation seal space.During crankshaft operation, lubricant grease is seeped in big end bearing from hole and lubricates, and extends lubrication time, improves running quality.Above structure is the structure of the form being different from above closed loop.Through contrast, under equal working condition, the equalizing orifice oil-bearing structure compressor operation life-span reaches more than 2500 hours and does not have the compressor of equalizing orifice oil-bearing structure, and running life, some life-spans were low to moderate less than 500 hours below 1500 hours.
It should be noted that, multiple schemes that this patent provides comprise basic scheme own, separate, mutually do not restrict, but it also can combine when not conflicting mutually, reaching multiple effect and jointly realizing.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
