Background technique
Usually said internal-combustion engine refers to internal-combustion piston engine, and internal-combustion piston engine is the most general with reciprocating piston type.Internal-combustion piston engine mixes fuel and air, and at its combustor inner cylinder, the heat energy discharged makes to produce in cylinder the combustion gas of High Temperature High Pressure.The work done of combustion gas expansion pushing piston, then by connecting rod or other mechanisms, mechanical work is exported, drive follower work.
Internal-combustion engine generally comprises housing, in housing, be provided with crankshaft and piston, piston is placed in firing chamber, bent axle is connected with piston by connecting rod, when under the driving of piston at chemical energy, doing reciprocatory motion, piston rotates by connecting rod band dynamic crankshaft, and bent axle drives output shaft rotation by driving mechanism after rotating.
General internal-combustion engine such as the disclosed internal-combustion engine with multi-cylinders of patent (CN85108944), the cylinder head of placing and fixing thereon with delegation or multirow on crankcase, cylinder head is vertical with the vertical working surface of internal-combustion engine, and mutually near, the monolithic cylinder head of every row clamps with at least one anchor bolt, said anchor bolt with internal-combustion engine vertically by or ooze to run through and pass through cylinder head.These internal-combustion engines all only have a bent axle.
In the equipment such as some steamers, power plant, all have internal-combustion engine, but these internal-combustion engines are all large-scale, the bent axle single part is greatly to tens tons to the hundreds of ton, piston also greatly to tens ton to the hundreds of ton.These large-scale internal-combustion engines are because the weight of part is very large, and slewing rate is very low in work, and single bent axle shakes very large in by piston driving, cause internal-combustion engine output unstable, and working life is low.Simultaneously, the bent axle of internal-combustion engine is due to very huge, and a whole manufacture is very difficult.
Summary of the invention
The present invention is directed to the problems referred to above that existing technology exists, a kind of internal-combustion engine and driver element thereof of double-crankshaft self balancing is provided, technical problem to be solved by this invention is: the vibration problems how large quality bent axle of the large quality piston driving of balance brings.
Purpose of the present invention can realize by following technical proposal:
A kind of driver element of internal-combustion engine of double-crankshaft self balancing, it is characterized in that, this driver element comprises cylinder and a pair of bent axle, respectively with one cylinder of a bent axle position corresponding, in cylinder, has piston, on bent axle, has axle journal, two crankshaft center lines are parallel and be arranged side by side, between two bent axles, be provided with and can make both keep locking phase to rotating and can transmitting for both the linking mechanism one of radial force, between the piston of described axle journal and correspondence, be provided with the driving mechanism that the described bent axle of piston actuated is circumferentially rotated, axle journal on two bent axles is symmetric.
Its principle is as follows: the cylinder of each driver element and bent axle are paired, every bent axle or piston are all that the hundreds of ton is above, two bent axles carry out synchronizing by linking mechanism one, because two bent axles be arranged in parallel side by side, two axle journals are symmetric, and two bent axles are again to rotate in opposite directions with identical rotating speed, by linking mechanism one, transmit both radial forces again, make two bent axles radially remain stress balance in work, thereby solved the problem that in the large combustion machine, single bent axle easily shakes at work.Simultaneously, two bent axles are better than the bearing capacity of single bent axle.
In the driver element of the internal-combustion engine of above-mentioned a kind of double-crankshaft self balancing, as the first scheme, described driving mechanism comprises kinematic link, and the upper end portion of described kinematic link and described piston are hinged, and the axle journal on the underpart of described kinematic link and described bent axle is hinged.The mode of kinematic link is relatively simple for structure, durable in use, and the two ends up and down of kinematic link are all articulated manner, and its fit system with bent axle and piston is very flexible.
In the driver element of the internal-combustion engine of above-mentioned a kind of double-crankshaft self balancing, as another kind of scheme, described driving mechanism comprises piston rod, sliding sash and slide block, the upper end of described piston rod and described piston are connected, the lower end of described piston rod and described sliding sash are connected, in described sliding sash, offer along bent axle chute radially, described slide block is slidably connected in described chute, and described slide block and described axle journal are radially fixed and circumferentially be rotationally connected.The upper end of piston rod can be connected and need not be hinged with piston, make both stability better, make the motion of piston rod and piston can be straight up and down, avoided the active force that piston tilted and the problem of shaking, because lower end and the sliding sash of piston rod is connected, both stability is also very good, owing in sliding sash, being provided with chute and slide block, make slide block can move along chute when the axle journal of bent axle rotates, thereby for being connected, the upper end portion of piston rod and piston provide condition, the advantage of this programme is that the stability of connection of top and bottom of piston rod is very good, slide block is also fine along the stability that chute moves.
In the driver element of the internal-combustion engine of above-mentioned a kind of double-crankshaft self balancing, described slide block middle part offers the mounting hole that bore and described axle journal diameter match, and described axle journal is plugged in described mounting hole.When bent axle rotated, axle journal can be with the movable slider synchronizing moving, and simultaneously, the inwall of axle journal and mounting hole can rotate, and adopted the mode of pegging graft to make the stressed relation of axle journal and slide block more stable, can not produce impact force.
In the driver element of the internal-combustion engine of above-mentioned a kind of double-crankshaft self balancing, each cylinder has a piston, and each bent axle has an axle journal.Its benefit is that the bent axle quality is too large, after segmentation, the corresponding lower end bent axle of cylinder, profile and the weight of single bent axle all diminish, easily processing, the corresponding multi-cylinder structural reform of a bent axle of transmission is become to the present corresponding single cylinder of a bent axle, and multipair single cylinder driver element combination forms the motor array, makes the power of internal-combustion engine greatly improve.
