Compared with the traditional connecting rod mechanism, what innovative designs have appeared in the connecting rod mechanism in recent years

1. Compared with the traditional connecting rod Compared with the mechanism, simulation analysis has been fully used in recent years, such as using vector methods to describe the movement and dynamic analysis of the plane connecting rod mechanism, and using ANSYS and other software to simulate the motion of the connecting rod mechanism model.

2. Bracket: A five-small innovative achievement of the trade union of Tangkou Coal Industry Company of Shandong Energy Zimin Group: "seaw" bracket connecting rod saves time and effort, and a lathe can easily handle 38-ton large-scale high-hydraulic bracket.

3. Scissors: Scissors are a simple connecting rod mechanism composed of two connecting rods and a turning point. This structure makes it easy for scissors to complete the cutting task. Bicycle: The pedals, cranks and axles of the bicycle form a connecting rod mechanism.

4. Compared with the plane connecting rod mechanism, the spatial connecting rod mechanism often has the characteristics of compact structure, diverse movement, flexible and reliable work, etc., but the design is difficult and the manufacturing is relatively complicated. Space connecting rod mechanisms are often used in agricultural machinery, light industrial machinery, textile machinery, transportation machinery, machine tools, industrial robots, prostheses and aircraft landing gears.

5. It is not like the cam mechanism, which sometimes needs to be closed by the spring equal force to maintain contact. Therefore, the plane connecting rod mechanism is widely used in various machinery, instruments and electromechanical products.

6, 3 The design method is relatively complicated. The most common thing is the crank piston connecting rod mechanism on the engine, which is also used in the air compressor.

What is the difference between crankshaft, crankshaft, connecting rod and camshaft

1. Camshaft and crank The difference between axes: First, the properties are different.Crankshaft: It is the most important part of the engine. Camshaft: It is a part of the piston engine. Second, the principle is different.

2. The journey refers to the combination of take-up and return. The closest position of the wheel rotation center to the farthest distance is the thrust (asse-up); on the contrary, the distance from the farthest position to the nearest position is the return, and the distance from which the moving follower in the thrust or return is called the journey, which is represented by h.

3. The camshaft is one of the important components of the gas distribution mechanism, which is passively driven. There is an essential difference between the two. There will be no mistake.

4. There is a camshaft and a connecting rod on the crankshaft connecting rod. The camshaft is one of the largest parts of the engine. When working, the camshaft rotates with the central shaft and drives the engine.

How big is the 195 connecting rod ratio

Connecting rod length/crank radius ratio is a railway science and technology term published in 1997. The time of publication was in 1997, and it was approved and released by the National Scientific and Technological Terminology Validation Committee. Source: The first edition of Railway Science and Technology Nouns.

The clothes that are one size larger than 195 are XXL. European size: xs=male height 155 female 160; s=male height 160 female 165; m=male height 165 female 170; L=male height 170 female 175; XL=male height 175 female 180; XXL=male height 180 female 185; XXXL=men's height 185 or more.

Q235 refers to steel with a yield strength of 235MPa, and the yield strength of Q195 is 195MPa, which is the main difference between the two. The rest of the physical properties do not have a great impact on the selection of materials.

What is the difference between the rotor engine and the traditional crank connecting mechanism engine? And the advantages? Seek a detailed explanation...

The operating noise is smaller: the piston movement of the reciprocating engine itself is a vibration source, and the valve mechanism will also produce mechanical noise; the noise of the reciprocating engine is very small when idling, but it does not mean that the noise is small when accelerating.

Both reciprocating engines and rotor engines rely on the expansion pressure generated by air-fuel mixed gas combustion to obtain rotational power.The difference between the mechanisms of the two engines is the way of using expansion pressure. In a reciprocating engine, the expansion pressure generated on the top surface of the piston pushes the piston down, and the mechanical force is transmitted to the connecting rod to drive the crankshaft to rotate.

In addition, the advantages of the rotor engine also include small size, light weight, low center of gravity, small vibration, etc. Features of the rotor engine The rotor engine can directly convert the combustion expansion force of combustible gas into driving torque.
