Abstract

The present invention relates to an intercrank included angle special crankshaft. It is characterized by that it mainly includes crankshaft with two crank structure and crankshaft with several crank structures, and the included angle between crank and crank of crankshafts is less than 180 deg, so that the times of that the pistons are simultaneously reached to cylinder pressure maximum position can be staggered, maximum centralized pressure borne by crankshafts can be dispersed and the power required for compressing air by utilizing crankshafts to drive pistons can be reduced, therefore the application power of compressor can be reduced and the energy source also can be saved.

Description

Intercrank included angle special crankshaft

Technical field the present invention relates to press the crankshaft type of place machine.

Background technique society at present goes up the bent axle that compressor uses, and the angle between its two crank is the straight angle.Crank starts simultaneously in straight angle position when crankshaft rotating is worked, and drives piston by piston rod and arrives the cylinder pressure maximum position simultaneously at one time.The pressure that bears of bent axle is concentrated and is made bent axle need big power could drive piston motion like this, correspondingly also needs big power engine could drive bent axle work.Make the big energy of having wasted of compressor consumed energy.

Summary of the invention the objective of the invention is to provide a kind of new-type intercrank included angle special crankshaft that can save a large amount of energy to society.This intercrank included angle special crankshaft since intercrank included angle less than 180 °, so be not the air that compresses at one time in the same section by each crank by the piston motion that piston rod drives, but each piston compresses the air in the different sections respectively.The piston that staggered arrives the time of cylinder pressure maximum position simultaneously, and the maximum focus pressure of having disperseed bent axle to bear has reduced bent axle and driven the power that the Piston Compression air needs, and has reduced the purpose that the use power of compressor has realized saving the energy.

In order to realize that purpose the present invention of the present invention has designed three kinds of representational intercrank included angle special crankshafts: a kind of be two intercrank included angles less than 160 ° bent axle 1, another kind be in a plurality of cranks any two intercrank included angles less than 130 ° bent axle 10, to also have a kind of be adjacent two intercrank included angles less than 100 ° bent axle 23.These three kinds of intercrank included angle special crankshafts is characterized in that: the angle that the crank 2 of bent axle 1 and crank are 3 is less than 160 °.Feature two: the angle that the crank 12 of bent axle 10 and crank are 13 is less than 130 °.Feature three: the angle that the crank 24 of bent axle 23 and crank are 25 is less than 100 °.

In the present invention, different according to compressor product structure and usage requirement, the size of angle can change arbitrarily between crankshaft crank.Angle just can be saved a spot of energy less than 160 ° between crankshaft crank, though intercrank included angle less than 130 ° then the crank of bent axle be that two crank structures or multicrank structure can both significantly be saved the energy, adjacent two intercrank included angles less than 100 ° bent axle just can be a large amount of the saving energy.

Description of drawings is told the present invention in detail below in conjunction with embodiment of the invention accompanying drawing.

Fig. 9 is that the intercrank included angle special crankshaft angle launches schematic plan view less than 100 ° of bent axle work structuring.

Embodiment is referring to accompanying drawing 1 to 9, and Fig. 1 and Fig. 2 have showed the bent axle 1 that two crank structures are arranged.3 angle R of the crank 2 of bent axle 1 and crank have angle R1 less than 160 ° between the crank 3 and the straight angle.A, B two places represent pressure extreme higher position point.When crank 2 moves to cylinder 6 pressure maximum positions by piston rod 4 drive pistons 5, because crank 2 and 3 angle R of crank are less than 160 °, so also differ distance L by the piston 8 that piston rod 7 drives apart from cylinder 9 pressure maximum positions by crank 3.Staggered like this piston 5 and piston 8 arrives the time of cylinder pressure maximum position simultaneously, and the maximum focus pressure of having disperseed bent axle 1 to bear has reduced bent axle and driven the power that the Piston Compression air needs, and has reduced the use power of compressor and has saved the energy.

Fig. 4 and Fig. 5 have showed the bent axle 10 that a plurality of crank structures are arranged.13 angles of the crank 12 of bent axle 10 and crank be 120 ° less than 130 °.Crank 13 tripping power extreme higher position point A differ 60 °, and crank 11 tripping power extreme higher position point B differ 120 °.When crank 12 moves to cylinder 16 pressure maximum positions by piston rod 14 drive pistons 15, because

crank

11 and 12 on crank,

crank

12 and 13 angles that have 120 ° of crank, so the piston 18 that is driven by piston rod 17 by crank 13 also differs the distance of L1 apart from cylinder 19 pressure maximum positions, the piston 21 that is driven by piston rod 20 by crank 11 also differs the distance of L2 from cylinder 22 pressure maximum positions.Can significantly find out by Fig. 6: have only piston 15 to be in cylinder 16 pressure maximum positions in six pistons that driven respectively by 10 3 cranks of bent axle, piston 18 all differs certain distance with piston 21 from the pressure maximum position of cylinder 22 and cylinder 19.Owing between crank and crank 120 ° angle is arranged, the tangible like this time of having staggered each piston arrives cylinder pressure maximum position, the maximum focus pressure of having disperseed bent axle 10 to bear has significantly reduced the power of bent axle 10 drive Piston Compression air needs.

What Fig. 7 and Fig. 8 showed is another bent axle 23 that two crank structures are arranged.The angle that the crank 24 of bent axle 23 and crank are 25 be 90 ° less than 100 °, crank 25 tripping power extreme higher position point A differ 90 °.When crank 24 moves to cylinder 27 pressure maximum positions by piston rod 25 drive pistons 26, because

crank

24 and 25 on crank have 90 ° of angles, so also differ the distance of L3 apart from cylinder 30 pressure maximum positions by the piston 29 of piston rod 28 drives by crank 25.Very significantly staggered piston 26 and piston 29 arrives the time of cylinder pressure maximum position simultaneously, the maximum focus pressure of having disperseed bent axle 23 to bear has reduced the power of bent axle 23 drive Piston Compression air needs, has reduced the energy consumption of compressor and has saved the energy.

Comprehensive the above, the intercrank included angle special crankshaft of the invention, because so the crank of bent axle and intercrank included angle are less than 180 ° of times of having staggered each piston arrives cylinder pressure maximum position, the maximum focus pressure of having disperseed bent axle to bear, reduced bent axle and driven the power that the Piston Compression air needs, the corresponding use power that has reduced compressor has reduced energy consumption and has saved the energy.
