Abstract

PURPOSE:To convert reciprocation into rotation in an efficient manner, by using a rack performing rectilinear motion and a freewheel fitted with pinions. CONSTITUTION:A rack is installed in each of piston rods 6, 7, 8 and 9, while pinions 10, 11 and 12 attached to a support rod 15 are held between each of these piston rods 6-9, and a rotary shaft fitted with freewheels 3 and 4 provided with these pinions 10, 11 and 12 is locked at a right angle to these piston rods 6-9. The rack of these piston rods 6-9 is engaged with each of a pinions 1 and 2 so that rectilinear motion in these piston rods 6-9 due to explosion of each of cylinders 16 and 19 makes these pinions 1 and 2 rotate, and the free wheels are set in motion, giving turning force to the rotary shaft 5, whereby reciprocation is convertible into rotation in an efficient manner.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanism for efficiently converting reciprocating motion into rotary motion.

Conventionally, cranks have been used as a mechanism for converting reciprocating motion into rotary motion, but since the connecting rod and crank arm are in a straight line at top dead center, there is a drawback that it is difficult to obtain rotary motion in this vicinity. Also, since the connecting rod was tilted, frictional force was generated between the piston and the cylinder.

The object of this invention is to prevent the rotational movement from occurring at the top dead center of the reciprocating motion, and to prevent the connecting rod from tilting, thereby preventing the generation of frictional force between the piston and the cylinder.

In addition, the previous invention [mechanism to change reciprocating motion to rocking motion and obtain rotational motion (57-048898)] and [mechanism to change reciprocating motion to alternating rotation and obtain rotary motion] (58-125686)
In this case, since the direction of the torque caused by the explosive force changes alternately, a mechanism was needed to change the alternate rotation to rotation in a fixed direction. In this invention, even if the two cylinders explode, the direction of torque remains the same, so rotational power can be obtained only from the freewheel.

In the previous invention, the mechanism served both as a link to reciprocate the pistons of each cylinder and to provide torque as motive power, but in this invention, two separate mechanisms are used to perform the two functions.

An example in which the present invention is applied to a reciprocating engine will be described below with reference to the drawings.

1 to 3 show the case of a 4-cycle cylinder, in which the cylinders are arranged in the same direction, and the piston rods 6 and 9 and 7 and 8 are provided with racks on two sides. A pinion 10, 11, 12 attached to a support rod 15 is sandwiched between each piston rod.

A rotating shaft 5 with a seven-wheel wheel 3.4 provided with a pinion is fixed at right angles to the piston rod. The mechanism consists of a support rod 15 to which rotating bodies 13, 14 are attached to guide the piston rod so that it does not tilt.

The linkage mechanism for reciprocating each piston consists of a rack provided on each piston rod and a pinion 10, +
1S12. If the first stroke is cylinder 16 explosion, cylinder 17 exhaust, cylinder 18 intake, and cylinder 19 compression, pinion 10 rotates to the left, pinion 11 rotates to the right, and pinion 12 rotates to the left. Each cylinder is stroked. In the second stroke, the cylinder 16 exhausts, the cylinder 17 suctions, the cylinder 18 compresses, and the cylinder 19 explodes. Each pinion rotates in the opposite direction to the first stroke. In the third stroke, cylinder 18 is in the explosion stroke, and in the fourth stroke, cylinder 17 is in the explosion stroke, and the pinion rotates alternately.Thus, each cylinder performs a stroke in sequence, and in the fifth stroke, it returns to the first stroke. Below the edge I) is returned and the piston performs a reciprocating motion.

Next, the mechanism for increasing the rotational power is as follows. Since the racks of screw rods 6 and 9 are meshed with pinions 1 and 2, respectively, the linear movement of the piston rods due to the explosion of cylinders 16 and 19 rotates the pinions, and the freewheel is activated by the rotating shaft 5. gives rotational force to.

Further, when the cylinder 17 explodes, the linear motion of the piston rod 7 is transmitted as a linear motion to the piston rod 9 via the pinions 11 and 12, causing the pinion 2 to rotate, the freewheel 4 to operate, and the rotation shaft 5 to rotate. Gives rotational force.

Similarly, the linear motion of the piston rod 8 due to the explosion in the cylinder 18 is transmitted to the piston rod 6 via the pinions 11 and 10, causing the pinion 1 to rotate and the freewheel 3 to operate, thereby applying rotational force to the rotating shaft 5. The freewheel does not operate when the piston rod returns. Since the freewheels 3.4 operate in the same direction of rotation, the linear firing J of the piston rod due to the explosion of either cylinder always causes the rotation axis 5 to rotate in the same direction.

The cross-sections of the piston rods 6 and 9 are triangular, and the guide rotating bodies 13 and 14 are mounted diagonally. This is to make you do it with your body.

In a 2-stroke ennon, this mechanism reciprocates with two cylinders, providing rotational motion.

Fig. 4.5 also shows the case of a 4-cycle cylinder, the cylinders are arranged in the same direction, and a pin 38 is attached to the tip of each piston rod. In order to allow the piston rod to move in a straight line, a horizontally long groove 37 is provided at the tip of the piston rod, and the swinging part 37 is fitted into a pin and moves in a swinging motion.29.30.3
1 onto the support rod 32.
A rack is provided to mesh with the pinions 20 and 21. Install the pinion (remove the sun 7 lee wheel 22.23)
It is a mechanism in which an I-digit rotating shaft 24 is fixed at right angles to the piston rod.

The interlocking mechanism for reciprocating each piston is performed by a swinging member 29, 30, 31, which has a horizontally long groove 37 in a pin 38 installed at the tip of each piston.In the first stroke, the cylinder 3 is an explosion, cylinder 34 is exhaust, cylinder 35 is intake,
When the cylinder 36 is in each compression stroke, the swinging part 29 swings counterclockwise, the swinging member 30 swings clockwise, and the swinging member 31 swings counterclockwise, thereby completing each cylinder's stroke. In the second stroke, the cylinder 33 is the exhaust, the cylinder 34 is the intake, the cylinder 35 is the pressure 1, and the cylinder 36 is the explosion. It will be done. In the third stroke, the cylinder 35 is in the explosion stroke, and in the fourth stroke, the cylinder 34 is in the explosion stroke.As the rocking member swings like a seesaw, each cylinder performs a stroke in sequence, and in the fifth stroke, the cylinder 34 goes into the first stroke. Returning and repeating the process, the piston performs a reciprocating motion.

Next, the mechanism for obtaining rotational power is as follows. Since the racks of piston rods 26 and 27 are engaged with pinions 20 and 21, respectively, the linear movement of the piston rods due to the explosion of cylinders 34 and 35 rotates the pinions, actuating the freewheel, and exerting the same force on the rotating shaft 24. give.

Further, when the cylinder 33 explodes, the linear movement of the piston rod 25 is transmitted to the piston rod 27 as a linear movement via the swinging members 29 and 30, causing the pinion 21 to rotate (to rotate the freewheel 23).
operates to apply rotational force to the rotating shaft 24. Similarly, the linear movement of the piston rod 28 due to the explosion of the cylinder 36 is transmitted to the piston rod 26 via the swinging members 31 and 30, and the pinion 2
0 rotates, the freewheel 22 operates, and the rotating shaft 24
Apply rotational force to J). Since the freewheels 22 and 23 operate in the 11th direction at the same time and do not operate when the piston rod returns, the piston rod 1 due to an explosion in either cylinder
The α-ray motion always rotates the rotating shaft 24 in the same direction.

In this 62-cycle ennon, two cylinders make reciprocating motion and rotational motion is obtained.

Figures 6 to 8 show the case of two cycles, and the cylinders are arranged in the same direction. Both ends of the chain 47 are attached to the tip of each piston rod and are hooked onto the chain gear 46. A 1'1 gear is installed on the support rod 50, and rotating bodies 48 and 49 that guide the piston rod to prevent it from tilting are also installed. Piston rod 44.45
A rack is provided for the pinion and engages with the pinion 39.40. It is a mechanism in which a rotating shaft 43 with a freewheel 41, 42 provided with a pinion is placed at right angles to the piston rod.

The reciprocating movement of each piston is effected by a chain 47 and a chain gear 46, which are connected to the piston rod. In the 2-cycle, the cylinder 51 explodes every two strokes. When the cylinder 51 explodes in the -th stroke, the 1'1 gear 46 rotates to the left and the strokes of each cylinder are performed. When the cylinder 52 explodes in the second stroke, the chain gear rotates in the opposite direction to that in the first stroke, and each stroke of t1 is performed. As the chain gear rotates alternately, each cylinder sequentially performs a stroke, returns to the first stroke at the third stroke, and repeats the process, causing the piston to perform reciprocating motion.

The mechanism for obtaining rotational power is as follows. cylinders 51 and 52
The linear movement of the piston rod by the tB force rotates the pinions 39 and 40, respectively, and the free wheels 41 and 112 operate to apply rotational force to the rotating shaft 43. Since the 7 Lee wheels 41 and 42 operate in the rotational direction and do not operate when the piston rod returns, linear movement of the piston rod by the k1 shot of any cylinder always rotates the rotating shaft 43 in the same direction.

The mechanism that obtains rotational motion from the reciprocating motion of the piston in this way is more efficient than the conventional crank mechanism.
As is clear from Figure 8, the linear impulse direction of the piston and the radius of rotation of the rotating shaft always act at right angles to each other. Furthermore, since the piston rod does not tilt during the reciprocating movement of the piston, no frictional force is generated between the piston and the >-c member. However, the mechanism using the swinging member shown in Fig. 4.5 has a slight loss when the piston rod and the swinging member are tilted from a right angle.

Although a reciprocating engine is used as the reciprocating motion in the embodiment, rotational power can be obtained by using reciprocating motion by human power or various other forces.

As explained above, in this invention, rotational force can be obtained even at the second dead center of reciprocating motion, and since the piston rod does not tilt, no frictional force is generated between the piston and the cylinder. That is, there is an effect of efficiently converting reciprocating motion into rotary motion and making the reciprocating motion occur smoothly.

Further, in the case of a method such as the present invention, a holder is required to reliably and smoothly guide the reciprocating member. Such a holder that makes line contact parallel to the direction of movement of the reciprocating member can reliably guide the reciprocating member with less frictional resistance. 9.10.11 shows the rotating body 13.
This is an example in which a line contact holder 67°58 is applied to the piston rods 53, 54, 55, 56 instead of the piston rod 14 to guide them. In the figure, the holder 57 is an example of one-line contact, and 68 is an example of two-line contact. The reason why the holder 68 is made into two-line contact is to guide the piston rod more reliably.If a -line contact is acceptable, the cross section of the portion that contacts the piston rod may be made into a corner or an arc shape.
