Description
Technical field
The mechanism of the mutual conversion that the present invention relates to to-and-fro motion and rotatablely move is specifically related to circular slider-crank mechanism.The equipment that the present invention relates to a kind of bent axle of this circular slider-crank mechanism simultaneously and uses this mechanism.
Background technique
In traditional internal-combustion engine and compressor, realize the conversion between the rotatablely moving of to-and-fro motion and bent axle of piston through connecting rod.Yet shortcomings such as because the existence of connecting rod, that the internal-combustion engine of connecting rod and compressor have is bulky, heavy, balance quality difference.
For addressing the above problem, the authorization day for announcing is that the Chinese patent that January 13, notification number in 1988 are CN85100358B discloses a kind of " crankshaft circular slide block reciprocating piston internal combustion engine ".Authorization is that the Chinese patent that December 14, notification number in 1988 are CN85100359B discloses a kind of " crankshaft circalar slide block reciprocating piston compressor " day for announcing.In disclosed internal-combustion engine of said Chinese patent and the compressor, replaced connecting rod, as the mechanism of to-and-fro motion with the conversion that rotatablely moves with circular slider-crank mechanism.Wherein, in circular slider-crank mechanism, comprise smooth block, piston and bent axle; Smooth block is provided with eccentric circular hole; The piston seat of piston is provided with circular slider accommodation hole.During assembling, be arranged in the described circular slider accommodation hole smooth block is rotatable; The crank pin of bent axle is rotatable to be assemblied in the described eccentric circular hole.
Be example with the internal-combustion engine below, the working method of above-mentioned circular slider-crank mechanism is described.During work; Combustion gas in the firing chamber expand and promote piston motion; Driving the smooth block that is arranged at wherein through piston moves reciprocatingly; And smooth block rotates in said piston simultaneously, and said to-and-fro motion rotates around the central axis of bent axle with the synthetic central axis of the eccentric circular hole on the smooth block that makes that rotatablely moves; And the dead in line of the crank pin of the central axis of said eccentric circular hole and bent axle, thereby can realize the conversion that rotatablely moves that reciprocates to bent axle of piston.During compressor operating, process is just opposite.
In the disclosed technological scheme of above-mentioned Chinese patent, need to adopt an internal gear transmission structure, solve the problem of the point of living.Yet this structure is only applicable to single cylinder engine, and this dynamic balance performance is not ideal enough.
Based on this; Notice of authorization day is June 27 calendar year 2001, notice of authorization number to disclose a kind of " crank and double-round slide reciprocating piston internal combustion engine " for the Chinese patent of CN1067741C; In this internal-combustion engine; Be the smooth block composition circular slider set that 180 degree are provided with through two phase differences, two smooth blocks place the orthogonal reciprocating part of vibration-direction respectively.During work, orthogonal reciprocating part can overcome the some problem of living each other, and can reciprocal inertia force separately be transformed into centrifugal inertia force, thereby is convenient to it is carried out balance.Has better counterbalance effect.
Notice of authorization day is June 27 calendar year 2001, notice of authorization number to disclose a kind of " crank and multi-round slide reciprocating piston internal combustion engine " for the Chinese patent of CN1067742C; In this internal-combustion engine; Have three smooth blocks; Adjacent smooth block phase difference also is 180 degree, thus form be positioned at the middle circle slide block respectively be positioned at the two terminal circle slide block and be 180 degree phase differences, and be positioned at the identical circular slider set of two ends two smooth block phase places.The smooth block that phase place is identical places the parallel reciprocating part of vibration-direction, and phase difference be 180 the degree smooth block place the vertical reciprocating part of vibration-direction respectively.
For the mechanism of the circular slider set of three smooth blocks, also can orthogonal reciprocal inertia force be converted into centrifugal inertia force and can overcome the some problem of living of single smooth block mechanism.And the mechanism of three circular slider set is with respect to the mechanism of double-round slide group, and all right balance reciprocal inertia force square has better counterbalance effect.
Yet, because in the mechanism of three circular slider set, three smooth blocks being set on one-throw crankshaft, this makes that the span of crank pin of one-throw crankshaft is bigger.When this mechanism is applied to internal-combustion engine or compressor, can cause crank pin bending deflection.Particularly the reinforcing degree along with internal-combustion engine improves constantly; The gas pressure that acts on the piston is increasing; And adopt supercharging, in the diesel engine maximum outbreak pressure of technology such as cold, high-pressure common rail bigger, rotating speed is also higher, the pressure that piston bears and the reciprocal inertia force of this piston all can act on the crank pin of bent axle, particularly the quality of dynamic balance slide block is two piston mass sums; The reciprocal inertia force of its generation is bigger, and this has more aggravated the bending deflection of crank pin.And improve the intensity of crank pin through the method that strengthens crank pin diameter, be difficult to carry out owing to the restriction of the matching relationship that receives crank pin and smooth block, piston and the restriction of entire mechanism total quality again.Thereby the application of the circular slider-crank mechanism that has limited three smooth blocks on equipment such as the internal-combustion engine of high tenacity demand and compressor.
