Description
Technical field
The present invention relates to fluid driving equipment technical field, and in particular to a kind of rocking bar driven fluid power plant.
Background technology
Reciprocating moving mechanism is widely used in compressor, engine and various fluid pumps, and its most typical form is
Crank connecting link reciprocating mechanism, it is mainly made up of parts such as crank, connecting rod, piston or sliding blocks, wherein one end of connecting rod with
Crank is rotatably assorted, and the other end and the piston or sliding block of connecting rod coordinate, and is achieved in rotary motion and piston or the sliding block of crank
Reciprocating conversion.It is well known that the connecting rod of traditional crank linkage is operated with the motion mode swung, therefore
The power that connecting rod is applied on piston is the power of a swing, and undoubtedly it will cause piston to produce slap to cylinder and cause
Noise, and piston is produced larger lateral pressure to cylinder and is increased frictional dissipation.In order to overcome traditional crank linkage
Above-mentioned drawback, people then seek that the mechanism of linear reciprocation driving piston or sliding block can be realized, wherein a kind of straight in the prior art
Line reciprocating mechanism scheme as depicted in figs. 1 and 2, it have a pair of sizes identical and be intermeshed and turn to opposite gear 1,
2, and it is each provided with handle pin 11,22 on the two gears 1,2 specular, it is additionally provided with a seesaw frame 3, seesaw frame
The guide groove 33 of long straight shape is provided with 3, two slide rails being parallel to each other A, B are provided with guide groove 33, above-mentioned handle pin 11,22 is inserted simultaneously
Enter in the guide groove 33 and coordinate with slide rail A, B, or be set with after roller 4 on handle pin 11,22 and coordinate again with slide rail A, B；Set in addition
It is equipped with piston or sliding block 5 and is connected with guide rod 6 with seesaw frame 3, piston or sliding block 5 is slidably matched with cylinder body 7.When gear 1,2 is nibbled
When closing rotation, handle pin 11,22 thereon will be directly or indirectly applied on slide rail A, B of guide groove 33, and therefore drives seesaw frame 3
Motion is produced, is not difficult to find out, straight reciprocating motion is necessarily made based on the above-mentioned seesaw frame 3 of symmetrical reason, piston now or cunning
Block 5 is also necessarily straight reciprocating motion.But found through practice, above-mentioned linear reciprocating mechanism improvements still in need,
It is mainly manifested in：1) first, slide rail A, B and the fit clearance of handle pin 11,22 or roller 4 are in the awkward condition of dilemma,
If fit clearance acquirement is too small, it will make handle pin 11,22 or roller 4 easily while touch two slide rail A, B, as a result cause them
Roll not smooth and increase friction loss, and if both fit clearance acquirements are excessive, then when will certainly cause to move back and forth again
Produce very big impact noise；2) secondly, the reciprocating motion of seesaw frame 3 and piston or sliding block 5 certainly exists reciprocal inertia force, many
Well known be this reciprocal inertia force be cause mechanism produce vibration noise the main reason for one of；3) finally, yi word pattern is put down
The guide groove 33 and slide rail A, B of straight shape can only make piston or sliding block 5 obtains such as simple harmonic motion of single motor pattern, and can not be by
According to needing to obtain some specific characteristics of motion, for example compressor wishes to control piston 5 to move slowly in compression exhaust stroke
Some then wish piston 5 in suction stroke and move sooner to improve operating efficiency to reduce exhaust Explosive noise.
Some also having at present, which move back and forth product, to be all by lead limit switch or changes power source power output side
Always realize reciprocating, this kind of product is all more complicated in control and structure, and manufacture and maintenance cost are high.
