Description
The present invention relates to connecting rod in the transmission device, particularly the linear reciprocating motion and the connecting rod of conversion mutually that rotatablely moves.
The connecting rod of prior art does not have to utilize well each part of equipment, and loss is bigger.And both rationally practical mechanism in the mechanism that the wobble crank linkage mechanism is until now to be proposed in of the present invention.At U. S. Patent 3,807, the 897 V-type connecting rods that propose, its shortcoming is that the utilization of every part of equipment is increasing equipment volume and weight, the motion speed that slows down is a cost.
And purpose of the present invention just is not increase under the prerequisite of equipment volume and weight, improves the space utilization ratio of equipment, improves the stroke of motion speed and piston, and equilibrium of forces is used in the above balance exercise of realization second order.
Imagine two (tooth) hypocycloids " back speed " and become two line segments that repeat twice.Make a differential gear train, its little circle radius is half of big circle radius.The roundlet one side is revolved round the sun around the great circle center of circle, one side is to double the reverse rotation of revolution speed, thereby with the linear reciprocating motion and the conversion mutually that rotatablely moves, according to this principle, cranking arm of bent axle is divided into two sections: a section of circular movement done that has main journal is cranked arm for circumference, the other end has bearing support, and is furnished with corresponding bearing (or making the pin of cranking arm), and that section that links to each other with crank pin is cranked arm for interior pendulum.Its another section has the pin of cranking arm (or make bearing hole and be furnished with corresponding bearing), and the pin of cranking arm is installed in the corresponding bearing, becomes a complete crank mechanism.The bearing support center is to the distance at main journal center, be the brachium and the distance of pin center of cranking arm that circumference is cranked arm to the crank pin center, the brachium that pendulum is cranked arm promptly equates, working stroke is regarded as big diameter of a circle, the main journal axle center is the center of circle of great circle, circumference crank arm brachium add in the pendulum brachium of cranking arm be big circle radius.In the pendulum brachium of cranking arm be little circle radius, the pin center of cranking arm is the roundlet center of circle, the track of roundlet center of circle motion overlaps fully with crank pin bearing center.Because crank pin is installed in the bearing by the pin of cranking arm, when a linear reciprocating motion was passed to crank pin by connecting rod, just one side was with velocity reversal's rotation of two times of revolution for crank pin, and one side revolves round the sun around the main journal center.Time rotational converts linear reciprocating motion to by crank pin and rotatablely moves.The promotion circumference is cranked arm running torque is exported during motion.Vice versa.
From said mechanism as can be seen, the present invention makes the swing of connecting rod change into linear reciprocating motion under the prerequisite that does not increase mechanism's volume or weight, thereby makes mechanism fast, flexibly, and loss reduces, and efficient improves.
Exert oneself in order to improve internal-combustion engine, more be to use turbo charging installation at present.And the shortcoming of turbo charging installation is to set up new complicated mechanism, takies sizable space, and weight of equipment is increased, thereby has placed restrictions on the using scope of equipment.
According to the supercharging principle of internal-combustion engine, compression enters the part inflation before the cylinder, can improve the internal-combustion engine output power.
Descent of piston when imagination utilizes the firing chamber to expand, gas is compressed in the piston base air chamber, thereby reaches the purpose of supercharging.
Connecting rod of the present invention applies to quartastroke engine when making transmission device, and the straight line motion of connecting rod makes us can utilize the space of piston base.
The stressed sketch of accompanying drawing 1 expression connecting rod and interior wobble crank linkage mechanism.
Wobble crank schematic diagram of mechanism in accompanying drawing 2 expressions.
The wobble crank linkage mechanism is as the cross-sectional diagrammatic sketch of quartastroke engine transmission part in accompanying drawing 3 expressions.
As shown in Figure 1, 2, crank mechanism is by power take-off or claims the rear end, free end or title front end, crank part-the crank-pin (1) that links to each other with connecting rod, circumference is cranked arm and interior pendulum crank arm connecting place-pin of cranking arm (2), (2 '), and be bearing in trunnion (3) in the base bearing on the body, compositions such as (3 '). For eliminating the swing of crank, in the bent axle front and back end, leave bearings mounted front end-journal (5) and rear end-journal (6). Circumference is cranked arm, interior pendulum is cranked arm, and two parts have rotatability mutually, and it is guaranteed by the pin bearing of cranking arm on cranking arm. Axial location is by the flange of base bearing and be installed in the pad that the antifriction alloy on the pin of cranking arm is made (4) adjust.
As shown in Figure 3, cylinder (7) is arranged in the both sides of internal combustion engine symmetrically, and piston (6) is installed in the cylinder by connecting rod (5). And the three is on same center line. Connecting rod can be circular cross section, and the tension of rod member, Compressive Strength are improved. The big end shape is made at the middle part, adopts two halves to coincide, and inner surface is connected with crank-pin with corresponding antifriction alloy axle bush, and is flexible with what guarantee to move. Because two row cylinders stagger 180 °, thereby reciprocating motion balance inertia is balanced.
For four-stroke engine, connecting rod is under the restriction of piston component, can only do reciprocating linear motion, utilize the space of cylinder bottom, mounting cover (8) is connected in cylinder bottom, and sealing ring (9) is installed in connecting rod and mounting cover contact position, reduce gas leakage, intake valve (10) and air bleeding valve (11), on the sidewall of mounting cover and cylinder bottom, the relative motion of can open, closing. Form a pressure ratio and be 2: 1 booster.
When internal combustion engine was up, cylinder bottom air chamber (13) volume increased, and pressure reduces, and when air pressure was lower than atmospheric pressure, one-way exhaust valve (11) was closed, and breather cheek valve (10) is opened, and fresh air enters air chamber (13).
When internal combustion engine was descending, air chamber (13) volume reduced, and pressure increases, and when its pressure during greater than air flue (12) Air pressure, breather cheek valve (10) is closed, and one-way exhaust valve (11) is opened, and fresh air enters air flue (12) through overcompression.
Thus, crank whenever rotates a circle, and fresh air is full of air chamber (13) once and enters air flue (12) through precommpression. Because just each air inlet of quartastroke engine revolution two week, compression, work done and exhaust are once, so that stores in the air flue (12) has a certain pressure, volume is that 2 times of fresh airs to volume of cylinder will enter cylinder when internal combustion engine intake valve is opened. Therefore, just can to obtain a pressure ratio be 2: 1 piston super charger to quartastroke engine.
Because interior wobble crank linkage of the present invention can replace toggle, so can be used for linear reciprocating motion and the mutual conversion that rotatablely moves under the occasion widely.
By the interior wobble crank linkage mechanism of being invented, be used for two-stroke piston internal-combustion engine can increase cylinder dash than, reduce weight per horsepower, and can reduce the unit horsepower oil consumption.Improve internal combustion unit output power.
Interior wobble crank linkage mechanism also can be used for the piston bidirectional compressor, the machinery that be used to produce vibration, produces pressure, pulling force etc., crank pin is made eccentric hoop, and pendulum is cranked arm and being slidingly connected that circumference is cranked arm in realizing with the pin of cranking arm, and constitutes the eccentric hoop mechanism that does other curvilinear motions.Can be used for to-and-fro motion and the various mutual conversion that rotatablely moves.
