Description
Technical field
The present invention relates to a kind of Energy Project mechanical device, be specifically related to a kind of balance mechanism of double-module free piston internal combustion engine generator, belong to field of energy source power.
Background technique
In recent years, it is high that people are being devoted to seek a kind of energy conversion efficiency always, the piston internal-combustion generator that vibration noise is little, wherein, free piston IC linear generating set is a kind of novel energy conversion equipment formed after free piston IC engine and linear electric generator are coupled, free-piston and linear motor rotor are directly connected by it, form unique moving element---piston assembly.During system cloud gray model, the work done of gas in the jar burning expansion, promotes piston and drives mover to move, then producing electric energy, eventually through shorter bang path, fuel chemical energy is directly converted to electric energy.It has numerous Potential performance advantage, and as mechanical friction loss is few, compact structure volume is little, and energy transferring path is short, and burning and exhausting quality is good.
But due in free-piston generator, piston assembly is unique moving element, piston assembly its inertial force when to-and-fro motion cannot be balanced by other reciprocating mass, thus brings the vibration problem of whole power system.For making system balancing, the structural type that some researchers adopt multiple module paralleling to combine, can see CarterD, WechenerE.The free piston power pa ck:Sustainable powerfor hybrid electric vehicles.SAE 2003-01-3277,2003. in this structural type each module comprise two opposed cylinders and one group of piston assembly.By the motion controlling piston assembly in each module, their inertia wind tunnel is cancelled out each other, but this method need at least 4 group modules could balance reciprocal inertia force and moment, complex structure and synchronization control is difficult simultaneously, is difficult to realize product practical.
Summary of the invention
The object of the invention is at least to need 4 groups of modules to solve prior art, thus cause complex structure and synchronization control is difficult, be difficult to realize the practical problem of product, a kind of balance mechanism of double-module free piston internal combustion engine generator is provided.
The object of the invention is to be achieved through the following technical solutions.
A kind of balance mechanism of double-module free piston internal combustion engine generator of the present invention, mainly comprises the first free-piston generator module, the second free-piston generator module, tumbler gear, balancing pole.
First free-piston generator module mainly comprises: cylinder, piston, connecting rod, coil of stator of motor, electric mover.
Second free-piston generator modular structure is identical with the first free-piston generator modular structure.
Annexation: two free-piston generator wired in parallel are arranged, are provided with two tumbler gears between two connecting rods, each tumbler gear engages with the tooth bar on two connecting rods simultaneously, and among the space being arranged in coil of stator of motor and both sides cylinder respectively; Balancing pole is furnished with between tumbler gear and coil of stator of motor; Balancing pole is vertical with connecting rod; Tooth bar on balancing pole engages with tumbler gear; By tumbler gear, connecting rod is flexibly connected with balancing pole.
Working procedure: the piston of both sides is rigidly connected with connecting rod respectively, forms a piston assembly.First module left hand cylinder and the second module right cylinder produce pressure of explosion simultaneously, and the piston assembly promoted in the first module moves right, and promote piston assembly in the second module to left movement; Because two-piston assembly engages with two tumbler gears, then can ensure the axially synchronous backward motion of two-piston assembly; Tumbler gear engages each other with balancing pole again, the also synchronous backward motion of two balancing poles; Until the first module right hand piston and the second module left hand piston arrive top dead center simultaneously, produce pressure of explosion, enter next circulation.
In working procedure, the reversing motion of two-piston component synchronization, inertial force is in its axial direction cancelled out each other, and because two-piston arrangement axis does not overlap, can produce a moment of inertia during two-piston component movement.The wheelbase of the acceleration * two-piston assembly of the quality * piston assembly of the size=piston assembly of this moment; Equally, two balancing poles are synchronous backward motion under the drive of tumbler gear, and inertial force is also offset, but creates a moment of inertia equally, this moment the wheelbase of acceleration * two balancing pole of quality * balancing pole of size=balancing pole; Because connecting rod and balancing pole mesh together by tumbler gear, so the acceleration of piston assembly is equal in real time with the acceleration of balancing pole; The wheelbase of two balancing poles is greater than the wheelbase of two-piston assembly, so the less balancing pole of available quality balances the reciprocal inertia force square of piston assembly, eliminates system vibration.
