Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which a piston of a cylinder is reciprocated up and down once and stopped once for a while, and the effect of ventilation is sufficiently reached so that sufficient supply and exhaust of air to the cylinder can be achieved. The present invention relates to a structure in which a piston of a cylinder capable of further improving the volume efficiency is reciprocated up and down once and stopped once for a while.

[0002]

2. Description of the Prior Art There is no way to improve the efficiency of the volume of a cylinder that is often used, which is mainly due to a lack of intake air volume, and some open the intake port quickly and close it slowly,
Alternatively, it may be said that booster metering is added to reinforce, but as the piston speed increases, the intake time also becomes shorter, its function is also limited, and it is possible to reach a higher intake efficiency in the cylinder. You can't. In consideration of this point, the applicant of the present invention eliminates the above-mentioned drawbacks by inventing a structure in which the piston of the cylinder is reciprocated up and down once and stopped once for a while several years ago.

[0003]

However, since the structure is very complicated, the manufacturing cost is very high, and there is a problem that the guide board of the dovetail groove and the axial center of the auxiliary crankshaft are rapidly rubbed and damaged. there were. Therefore, it is an object of the present invention to provide a structure that solves the above-mentioned problems and causes the piston of the cylinder to reciprocate up and down once and stop once for a time.

[0004]

In order to solve the above problems, the present invention provides an auxiliary crankshaft, a first gear,
The first gear is composed of members such as a second gear, a main crankshaft, a housing and a piston assembly, and the first gear includes an upper axle and a lower axle, and the piston assembly is attached to the upper axle. The gear is fixed to the lower axle of the auxiliary crankshaft, the second gear is fixed in the housing and meshed with the first gear, the main crankshaft is provided in the housing, and its axial surface differs from the axial center. The central recess is provided, the different central recess serves to provide the lower axle of the auxiliary crankshaft, the housing serves to mount the second gear and the main crankshaft, and the rotating diameter of the main crankshaft assists. It is half the rotating diameter of the crankshaft and the piston of the first gear is The circle passes above the centerline tangent of the upper axle of the auxiliary crankshaft, the radius of rotation of the main crankshaft passes through the centerlines of the recesses of different centers, and the gears of the first and second gears When the first gear meshes with the second gear to rotate up and down or up and down, it produces a function of assisting the mutual position of the upper axle of the auxiliary crankshaft. The piston of the cylinder is characterized in that the piston reciprocates up and down once and then stops once.

[0005]

According to the above construction, when the first gear meshes with the second gear and rotates, a relationship that assists the position between the first gear and the upper axle of the auxiliary crankshaft is generated, and the piston assembly is generated. It acts to stop Lee one stroke up and down for one stroke.

[0006]

An embodiment of the present invention will now be described with reference to the drawings. As shown in FIGS. 1 and 2, the device of the present invention includes an auxiliary crankshaft 1, a sun gear 2 which is a first gear,
The internal gear 3, which is the second gear 3, the main crankshaft 4, the housing 5, the piston assembly 6 and other members are included. The auxiliary crankshaft 1 includes an upper axle 11, a lower axle 12 and an upper axle 11.
A piston assembly 6 is attached to fix the sun gear 2 above the lower axle 12 of the auxiliary crankshaft 1. Moreover, the pitch circle of the sun gear 2 passes above the centerline tangent line of the upper axle 11 of the auxiliary crankshaft 1 to fix the internal gear 3 in the housing 5 and tighten it with the screw 51. The main crankshaft 4 is inserted into the bearing 41 and fixed in the housing 5 at a gear ratio of the sun gear 2 to the internal gear 3 of 2: 3. A central concave portion 42 different from the central axis 43 is provided on the axial surface of the main crankshaft 4, and a bearing 421 is provided in the different central concave portion 42.
Is provided. When inserting the lower axle 12 of the auxiliary crankshaft 1 into the different central recesses 42 of the main crankshaft 4, the sun gear 2 also meshes with the internal gear 3.

FIG. 3 and FIG. 4 are operation explanatory views of an embodiment of the present invention. In the device of the present invention, the rotating diameter of the main crankshaft 4 is mainly half the rotating diameter of the auxiliary crankshaft 1. Moreover, the pitch circle of the sun gear 2 passes above the centerline tangent line of the upper axle 11 of the auxiliary crankshaft 1. The radius of rotation of the main crankshaft 4 passes through the center lines of the recesses 42 having different centers, and the gear ratios of the sun gear 2 and the internal gear 3 are combined in a ratio of 2: 3. Then, by utilizing the rotation angle of the internal gear 3, the sun gear 2 rotates 180 ° clockwise from 0 °.
When rotated, the sun gear 2 is the highest point A of the internal gear 3 in FIG.
The inner crank 3 rotates to the lowest point B, and the main crankshaft 4 also rotates 180 °. The auxiliary crankshaft 1 rotates 90 ° in the opposite direction and its upper axle 1
1 descends in half and piston assembly 6
To move down.

When the sun gear 2 rotates 360 ° in the clockwise direction (as shown in FIG. 4), the sun gear 2 also returns from the lowest point B of the internal gear 3 to the highest point A. Therefore, in this case, when the main crankshaft 4 also rotates 360 ° and the auxiliary crankshaft 1 rotates 180 ° in the opposite direction, the upper axle 11 of the auxiliary crankshaft 1 rotates.
Is lowered to the lowest, the sun gear 2 is raised, the upper axle 11 of the auxiliary crankshaft 1 is lowered to once reciprocate up and down to balance each other, and the piston assembly 6 is stopped for a while. Is rotated 540 ° in the clockwise direction, the main crankshaft 4 is also rotated 540 °, and when the sun gear 2 is also rotated from the highest point A to the lowest point B of the internal gear 3, the auxiliary crankshaft 1 is rotated in the opposite direction by 270 °. The upper axle 11 also rotates half way up from the lowest point as it rotates.

When the sun gear 2 rotates up to 720 ° in the clockwise direction by reciprocating up and down to stop the piston for a while, the main crankshaft 4 also rotates 720 ° and the sun gear 2 also rotates to the internal gear 3. It rotates from the lowest point B to the highest point A. Then, when the auxiliary crankshaft 1 rotates in the opposite direction by 360 °, the upper axle 11 also rises to the maximum and moves the piston assembly 6 upward to raise the piston, causing the piston to stop for one stroke in one stroke. Complete what you do.

As described above, according to the present invention, the rotating diameter of the main crankshaft 4 is used to reduce the rotating diameter of the auxiliary crankshaft 1 to half, and the pitch circle of the sun gear 2 is the upper axle 1 of the auxiliary crankshaft 1.

As described above, according to the present invention, the first gear meshes with the second gear to rotate, thereby generating a relationship in which the first gear and the upper axle of the auxiliary crankshaft assist each other in position. Then, the piston assembly is configured to stop one stroke up and down one stroke at a time, so that the intake efficiency in the cylinder can be improved and at the same time, the manufacturing cost can be reduced due to the simple configuration. It has the feature that it is not easily damaged.
