Description
Technical field
The present invention is a kind of new special motor, relates to generator, gas compressor and hydraulic press.
Technical background
Widely used on the current engineering, be the reciprocating compressor and the hydraulic press of power with the internal-combustion engine, form by two-part.In the to-and-fro motion of power section, become the output power that rotatablely moves through connecting rod, bent axle with internal combustion engine; In gas compressor or hydraulic press, become to-and-fro motion through connecting rod, bent axle again, drive gas compressor piston or hydraulic press plunger.Its structure was both complicated, and efficient is also low.Normally used is the generator of power with the internal-combustion engine, also is to drive generator with running shaft, and generating might not need rotation in fact.Because internal-combustion engine is a kind of to-and-fro motion originally, with the internal-combustion engine gas compressor, hydraulic press and the generator of power just, it is unnecessary rotating this process actual.With regard to internal-combustion engine,, also limited the further raising of performance because connecting rod and bent axle are arranged.
Though direct acting free piston type gas compressor, hydraulic press and reciprocable generator are also arranged now, edit various free piston compressors, hydraulic press, reciprocating generator described in " extraordinary engine principles and structure " as Zhu Xianding in 1998; The nineteen ninety-five Pierre. the international patent of invention that the strong. Li Jianuo of peace moral applies in China, linear electrical generator (95193464.3) etc., because control section is too complicated, or the incompatible shortcomings such as load that change rapidly, can not get using widely.I obtains the internal combustion reciprocating generator of ZL97226009.9 patent in May, 1999, owing to do not propose on-stream change compression ratio at that time and eliminated the concrete grammar that vibrates, also perfect inadequately.
Summary of the invention
The objective of the invention is to: simplify with the internal-combustion engine be power generator, gas compressor and hydraulic press mechanical structure and improve its efficient.The method that realizes this purpose is to save connecting rod and the bent axle of ordinary internal combustion engine in order to output power, the piston of internal-combustion engine and the plunger of generator mover, gas compressor displacer or hydraulic press directly are connected, it is become one, constitute internal combustion reciprocating generator, internal combustion reciprocating compressor or the reciprocal hydraulic press of internal combustion.In order to guarantee the running that motor is reliable and stable and to adapt to various operating modes, the internal combustion reciprocating engine is provided with the distribution wheel, takes ripe cam valve train, the oil spout of controlling combustion engine, inlet and outlet, be connected with the internal combustion engine bar by a light and handy connecting rod, drive the rotation of distribution wheel.Radially have an elongated slot on the distribution wheel, an end of groove inside connecting rod provides power by an electric wheel, can be movable in elongated slot.Regulate the eccentric distance of connecting rod and distribution wheel, can change the stroke of piston, compression ratio that can on-stream flexible change cylinder.
Described motor can be a single cylinder, also can multi-cylinder.Minicomputer can be made single cylinder, and the another side of symmetry is established a spring, adds the inertia of distribution wheel, does backhaul power.Twin cylinder engine is provided with a pair of umbrella gear on distribution wheel separately, by a steel pipe two pairs of umbrella gear are connected with a joggle, and constitutes lazy-tongs, to eliminate vibration.Multi-cylinder can be in upright arrangement, a shared bent axle.Motor can be a two-stroke, also can be four-stroke, can light, but also compression ignite, can natural aspiration, also can adopt supercharging, do not influence various devices such as additional exhaust gas purification yet.
Because the internal combustion reciprocating engine does not have the connecting rod and the bent axle of output power, cylinder does not have lateral pressure, so significantly reduced wearing and tearing, can change compression ratio flexibly again, be convenient to starting, can also increase substantially the cylinder effective pressure, raise the efficiency, reduce oil consumption and use and comprise pluralities of fuels such as combustion gas, gasoline, diesel oil, heavy oil.It is the new work engine of compact structure, energy-efficient, compliance with environmental protection requirements.
