Definitions
- crank mechanism performs the conversion of motion smoothly and continuously.
- the vertical force applied to the rotational force is 0 at the top dead center of the crank mechanism, and the following is 0 at the bottom dead center of ⁇ radians of 1.0 at the crank angle of ⁇ / 2 radians.
- This is the sin curve shown in Fig. 1. Crank angle.
- the total work of the force applied to the rotation from 0 to ⁇ radians is the area of the diagonal line surrounded by the sin carp. And for the combination of pinions and racks, the corresponding area is Oab Ti, and the area ratio is ⁇ : 2.
- a work volume equivalent to ⁇ —2 1.14 was not used in the past. The following shows that the work conversion rate is a sin curve.
- Fig. 3 shows the force in each direction at points A and B of the crank mechanism, and the displacement in a minute range when the force is applied.
- F represents force and d displacement.
- the angle between the perpendicular and the connecting rod is 0, and the crank rotation angle is J3.
- the pinion moves from its starting position ⁇ and reverses at the limit of the length of the rack so that it can return smoothly and continuously to the starting point.
- the conversion efficiency should be higher than that of the crank mechanism.
- the internal gear is made oval or elliptical and part of it is racked. 'And put this on the big end of the connecting rod.
- the external gear is connected to the output shaft.
- any part of the connecting rod can be used, but one or more pins are provided parallel to the output shaft, and these pins are inserted into a groove having a predetermined locus so that the gears are always in contact with each other. This will be described below with reference to the drawings. Note that the number of pins is one.
- 1 is a connecting rod, which has a biston pin hole at the small end.
- the large end is an internal gear 2 that is oval, elliptical, or similar.
- 3 is an external gear connected to the output shaft, and 4 is a guide pin.
- 5 is a guide groove that is opposite to the guide bin 4 and its shape is the guide rod of the connecting rod so that the gear does not come off. Is controlled so that it moves continuously and smoothly as shown by the arrows. The opposite direction is also possible.
- 6 is a guide wall provided on both sides of the connecting rod to prevent the connecting rod from moving in the direction of the output shaft. In this explanation, 5 guide grooves are each provided with 6 forces. You may make money.
- the biston's reciprocating linear motion force can be converted into rotational motion more efficiently than the crank mechanism. As a result, rotational power and output are increased, and fuel consumption is improved.
- the width of the machine is larger than twice the rotation radius of the crank and the biston f3 ⁇ 4, so in the present invention, the corresponding value is obtained by subtracting the gear of the output gear from the width of the internal gear. Value.
- the inner length of the internal gear of the present invention is naturally the same value as the Biston stroke, so the dimension of the direction of movement of the biston is also reduced, and the machine The overall size can be reduced.
- the Viston fi3 ⁇ 4 and the rotation of the crank are irrelevant, so a large stroke can be designed freely. This is advantageous for large diesels.
- the pump efficiency of the compression stroke is improved.
- the compression speed near the top dead center of the compression stroke is much faster than the crank mechanism because of its structure.
- the compression ratio can be increased.
- the internal gear Comparing the circumferential movement distance of the large end of the connecting rod and the linear movement distance of the internal gear, the internal gear is shorter. Can rotate at higher speed than the crank mechanism. Or, a longer stroke can be adopted if the rotation range is the same as the crank mechanism. Long strokes are known to have better fuel economy than short strokes.
- Figure 1 shows a combination of a rack and pinion, and a rectangle and sin curve that show the work efficiency when converting the crank mechanism to rotation.
- Figure 2 is a projection diagram of a device that converts linear reciprocating motion into rotational motion.
- 1 is a connecting rod
- 2 is an internal gear
- 3 is an external gear
- 4 is a guide pin
- 5 is a guide groove
- 6 is a guide wall.
- Figure 3 shows the force and displacement in the crank mechanism.
- F is the force at each point and d is the corresponding displacement.
- ⁇ , ⁇ , and 1 are 90 degrees, the angle formed by the connecting rod and the vertical, and the crack angle.
