Description

A kind of energy-saving engine

Technical field

The utility model relates to a kind of prime mover, particularly a kind of reciprocating engine.

Background technique

In the prior art, a kind of reciprocating engine is arranged, mainly comprise the piston that is arranged in the cylinder, the piston lower end is connected with connecting rod, the connecting rod lower end is connected with bent axle, during its work, the cylinder combustion oil firing promotes piston motion, and piston promotes bent axle through connecting rod and rotates, by flywheel energy storage or multi-cylinder interlock, can realize the backward stroke of the piston motion, for four stroke engine, piston back-and-forth movement is finished an operation cycle for twice, for two stroke engine, piston back-and-forth movement is once finished an operation cycle; Existing motor, its intrinsic deficiency is arranged, mainly show: at the ignition initial stage, the cylinder combustion oil firing, produce high temperature and high pressure gas, its thrust to piston is maximum in the entire work process, but this moment, piston was near upper dead center (generally at the before top dead center several angle), the crank of connecting rod and bent axle is substantially aligned, high temperature and high pressure gas to the thrust of piston through the main shaft of the crank of piston, connecting rod, bent axle, bent axle and act on the main bearing of supporting crankshaft, on the one hand, excessive thrust causes the main bearing eccentric wear easily, has reduced reliability; On the other hand, maximum thrust but can not form the moment of torsion of the maximum that promotes the bent axle rotation, has increased internal loss, has reduced mechanical efficiency; In addition, the inertial resistance of available engine is big, influences its power output.

The model utility content

The purpose of this utility model provides a kind of energy-saving engine, makes the use of motor more reliable, can also cut down the consumption of energy simultaneously.

The purpose of this utility model is achieved in that a kind of energy-saving engine, comprise piston, connecting rod and bent axle, described piston is arranged in the cylinder, the connecting rod lower end is connected with bent axle, be connected with sliding bar between described connecting rod lower end and the bent axle upper end, suit is fixed with a sleeve on the sliding bar, the sleeve both sides are respectively equipped with longitudinal rack, be provided with a driving gear with the longitudinal rack engagement of a side, be provided with one with the engagement of the longitudinal rack of other side and stablize gear, be coaxially arranged with the unidirectional movable pulley that drives once driving gear with driving gear, unidirectional movable pulley center is provided with output shaft; The sleeve inboard is provided with and is sleeved on the outer energy storage spring of sliding bar, conflicts on a spring seat in the lower end of energy storage spring, and sliding bar passes a fixed plate, is provided with guide bearing between fixed plate and the sliding bar.

During the utility model work, guide bearing, piston, stablizing gear and driving gear cooperatively interacts and can guarantee the sliding bar moving linearly, when sliding bar moves up and down, can promote bent axle and do rotation motion, when piston drive sliding bar moves downward, can promote unidirectional movable pulley rotation after reaching certain speed, and then the drive output shaft rotates, when driving gear angular velocity does not reach unidirectional movable pulley rotational angular velocity or sliding bar when up, unidirectional movable pulley keeps its original motion state, driving gear can not pass to output shaft with moment of torsion, but also can not stop output shaft to rotate; When motion bar is descending, energy storage spring is compressed, to after bottom dead center, the energy storage of energy storage spring discharges, promote sliding bar and piston stroking upward, the inertial force that energy storage spring can the reduce piston crank mechanism adverse effect that output produces to engine power has guaranteed the stationarity of crank up campaign, for the ignition by compression of next operation cycle provides good dynamics; Under the situation that multi-cylinder links, each cylinder provides at specific working stage and drives the power that output shaft rotates, and each cylinder constantly promotes the continual and steady outputting power of output shaft by its firing order collaborative work; Compared with prior art, the utility model makes piston only bear the thrust of above-below direction in cylinder, does not bear side-thrust, can avoid the eccentric wear of cylinder and piston; At the ignition initial stage, the thrust maximum that piston bears, the moment of torsion that therefore acts on the output shaft also is maximum, can reduce the thrust that the main bearing of bent axle bears, and avoids the main bearing eccentric wear; Simultaneously, can reduce the frictional heat that excessive thrust causes on main bearing, reduce internal loss, play energy-conserving action, improve mechanical efficiency.The utility model can used on four-stroke, two stroke gasoline, the diesel engine.

For the energy storage and the engine speed that make energy storage spring are mated more, be set with a guide sleeve on the described sliding bar, guide sleeve and fixed plate fix, guide sleeve is provided with outside thread outward, the internal thread that described spring seat is provided with through its center is connected with the outside thread outside the guide sleeve, the spring seat side is provided with horizontal tooth bar, described horizontal tooth bar is meshed with the tooth of spring seat periphery setting, described horizontal tooth bar and one drives the flexible centrifuge of this horizontal tooth bar and is connected, and the input shaft and the bent axle of centrifuge link.When the motor quick rotation, its strength that promotes piston stroking upward also needs adaptability to increase, at this moment, the bent axle rotational velocity is accelerated, and drives centrifuge through input shaft and rotates, and centrifuge drives horizontal tooth bar straight line motion, laterally tooth bar pulling spring seat rotates, spring seat can move axially along guide sleeve, can change the compression distance of energy storage spring like this, with the performance that obtains to be complementary with engine speed.
