Description
Technical field
The utility model is related to fluid driving equipment technical fields, and in particular to a kind of actuated by cams formula fluid dynamic dress
It puts.
Background technology
Reciprocating moving mechanism is widely used in compressor, engine and various fluid pumps, and most typical form is
Crank connecting link reciprocating mechanism, it is mainly made of components 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 are achieved in the rotary motion of crank and piston or sliding block
Reciprocating motion conversion.It is well known that the connecting rod of traditional crank linkage is worked 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 generate slap to cylinder and cause
Noise, and piston is made to generate larger lateral pressure to cylinder and increase frictional dissipation.In order to overcome traditional crank linkage
Above-mentioned drawback, people then seek to realize the mechanism of linear reciprocation driving piston or sliding block, 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 of size 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 mirror symmetry, it is additionally provided with a seesaw frame 3, seesaw frame
The guide groove 33 of long straight shape is provided on 3, two guide rail A, B being mutually parallel are provided on guide groove 33, above-mentioned handle pin 11,22 is inserted simultaneously
Enter in the guide groove 33 and coordinate with guide rail A, B or be set on handle pin 11,22 after roller 4 and coordinate again with guide rail A, B;In addition set
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 are 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 guide rail A, B of guide groove 33, and therefore drives seesaw frame 3
Movement is generated, is not difficult to find out, straight reciprocating motion is necessarily made based on the above-mentioned seesaw frame 3 of symmetrical reason, piston at this time or cunning
Block 5 is also necessarily straight reciprocating motion.However found through practice, above-mentioned linear reciprocating mechanism improvements still in need,
It is mainly manifested in:1) first, guide 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 guide rail A, B, as a result cause them
It rolls not smooth and increases friction loss, and if the fit clearance acquirement of the two is excessive, when will certainly cause to move back and forth again
Generate 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 generate vibration noise the main reason for one of;3) finally, yi word pattern is put down
The guide groove 33 and guide 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 cannot be by
According to needing to obtain some specific characteristics of motion, for example compressor wishes piston 5 is controlled to move slowly in compression exhaust stroke
Some then wish piston 5 in suction stroke and move sooner to improve work 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 what is moved back and forth, this kind of product is all more complicated in control and structure, and manufacture and maintenance cost are high.
The mechanism of reciprocating motion is realized by lead limit switch, since system acting number is frequent, limit switch pine
Failure rate caused by dynamic, failure is higher, poor reliability.
Change power source power output direction to realize the mode of reciprocating motion, it is necessary to which control system combination drive system is real
Existing, input cost is higher, and still has the shortcomings that poor reliability.
