[0002]

2. Description of the Related Art Conventionally, an example of a crank mechanism is generally formed as shown in FIG. 10 in the figure
1 is a crankshaft, 102 is a crank arm, 10
3 is a crank pin. Reference numeral 104 is a connecting rod, and 105 is a slider. And this slipper 1
Reference numeral 05 is slidably provided on the sliding portion 106. And, this crank mechanism is widely used in the case of converting rotary motion into reciprocating motion or vice versa.

[0003]

However, the above-mentioned conventional crank mechanism has the following problems. Assuming that the crankshaft 101 rotates in the direction of arrow A101 in FIG.
It can be moved in 5 directions. And in this case, the sliding member 105
It is preferable that the force of the connecting rod 104 exerted on the sliding portion 106 is purely in the axial direction of the sliding portion 106. However, when the rotational force of the crankshaft 101 is normally exerted on the slider 105 by the crank arm 102 and the connecting rod 104, the slider 105 receives a force 107 in the direction of the connecting rod 104. This force 107 applies a force 108 in the axial direction of the sliding portion 106 to the slider 105, and at the same time, the sliding portion 1
A force 110 in the direction of the right side wall 109 in the figure of 06 is applied. That is, a lateral pressure is generated. This lateral pressure creates a frictional force,
This restrains the movement of the slider 105 and reduces the efficiency.

The present invention has been made in order to solve the above problems, and its purpose is to make a slider actuated by a crank or vice versa.
It is an object of the present invention to greatly reduce the lateral pressure generated between the slider and the sliding portion, thereby providing a crank mechanism with improved efficiency over the conventional one.

[0007]

The crank mechanism of the present invention is constructed as described above, and the connecting rod 10 has the direct slider 1 as shown in the prior art.
No. 05 is connected to the connecting rod 1 which has wheels or bearings 9 rotatably positioned in the parallel passage 8 and is swingably provided on the slider 3. As a result, the lateral pressure on the sliding portion 2 generated by the operation of the connecting rod 10 causes rolling friction on the parallel passage 8 by the wheels or the bearings 9, and the friction is greatly reduced. Therefore, it is possible to provide a crank mechanism in which the efficiency of crank motion is improved as compared with the conventional one. Also, unlike the conventional reciprocating engine that uses the crank mechanism of the present invention to burn the fuel in the cylinder 17 to operate the piston 16, the connecting rod 10 is not directly connected to the piston, but the parallel passage 8 Since it is connected to a wheel or bearing 9 which is rotatably positioned therein, and this wheel or bearing 9 is swingably provided on the piston, the side pressure exerted on the parallel passage 8 by the connecting rod 10 rolls. Since it becomes friction, the friction in this portion can be greatly reduced. This can provide a reciprocating engine with improved efficiency.

This action is performed by the reciprocating engine whose fuel is gasoline and the reciprocating engine whose fuel is heavy oil or light oil, the expansion piston 26, the compression piston 27, the regenerator 29 and the cooler 30. The engine and the reciprocating engine using steam have the same operation and effect. Also in the compressor and pump, since the side pressure in the parallel passage 8 provided by the connecting rod 10 can be made into rolling friction, the friction can be greatly reduced, and an efficient compressor and pump can be provided. . Moreover, in the crank mechanism, the reciprocating engine, the compressor and the pump, the wheels or the bearings 9 alternately come into contact with one passage and the other passage of the parallel passage 8 during operation, and the rotation is in one direction.
Wheels or bearings 9 that can be in total contact
The wear can be reduced to a minimum. And if the wheel or bearing 9 rotates in contact with one of the paths, it can be automatically determined by the direction in which the connecting rod 10 is facing, so that the parallel path 8 and the wheel or bearing 9 are rotated. Can be made very small, so that the continuous movement of the wheel or bearing 9 between one passage and the other passage, i.e. the amplitude of vibration, can be made very small. Therefore, the noise generated at that portion can be reduced. Therefore, the wear generated in that portion can be made extremely small, and the life can be extended. Also, the operation can be made smooth.
