What is the function of the Lego large particle crank

Its function is to transform the recating movement of the piston into the rotational movement of the crankshaft and at the same time transform the force acting on the piston into the torque output of the crankshaft to drive the wheel of the car. .

The component in the crank slider mechanism that becomes a moving vice is the slider, and the component that connects the crank and slider by turning the vice is the connecting rod, which is evolved from the crank rocker mechanism in the hinge four-bar mechanism.

Cranks can be mechanically used to convert reciprocating motion into rotational motion. In 1400, someone connected the crank vertically to the connecting rod. When the crank was rotated, the connecting rod made a reciprocate movement. The crank and connecting rod are the main components of the steam engine, which can turn the reciprocating movement of the piston into a rotating movement and drive the machine.

There must be friction between any pair of surfaces of parts that are pressed together and move relative to each other, and its maximum value is determined by the positive pressure and friction coefficient formed by the friction surface of the above various forces.

The lubrication of the crankshaft mainly refers to the lubrication of the shaft tile between the rocker and the lubrication of the two fixed points. The crank is a component that is connected to the rack with a rotating vice and can rotate the whole circle around the rotating sub-axis. Loose cranks often make a clack.

The function of the crank connecting rod mechanism is to convert the thermal energy generated during fuel combustion into mechanical energy, and to convert the reciprocating motion of the piston into the rotational motion of the crankshaft through the connecting rod to output power to the outside world. The crank connecting rod mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion.

What does Lego automotive mechanical group mean

Lego mechanical group refers to the technological machinery products of the high-tech series, that is, the TECHNIC series. Lego Machinery Group is a brand-new construction field. You can use motors, gears, pneumatic devices, belt pulleys, connecting rods and other components to build models that can really move, and its particle parts can also be used in many EV3 works.

In the early days of the birth of the mechanical group, the parts system was very different from what it is now. The most important feature is that there is no panel and the use of convex hole beams. The construction method is somewhat similar to the current creative master series, but there is a big difference in mechanical linkage.

The difference between Lego mechanical group and original group: There is no difference between Lego mechanical group and technology group. Lego mechanical group, known as "technology group" abroad, is ego Technic series is a product line under Lego, which is free from tradition. Lego is mainly in the style of bricks.

City Group. According to the query car home website. The city group is the favorite Lego series of children of primary school age. This series is mainly in simulated cities.In various scenes, cars are also more realistic. Compared with the mechanical group, they are a little simpler, cheaper and cost-effective.

How to assemble the Lego Ferrari v12 engine

Lego engine + 3 cylinders should install the engine base and box, and install bolts. The engine barrel and engine cover are installed, and the crankshaft, valve, exhaust pipe, spark plug and other parts are installed on the engine. When the throttle valve is installed, the Lego engine + 3-cylinder assembly can be completed.

If the engine cover does not stand up, you can try the following method: recheck the whole construction process to ensure that each step is carried out according to the instructions or drawings, and all parts are installed correctly. If you find loose parts, you can try to reinforce them with some special Lego glue or some other available adhesives.

The difference between the V12 engine of Pacific Automobile Network and the V8 engine is that the engine has 12 cylinders and 8 cylinders. The more cylinders the V12 has, the more cylinders the engine has, the more difficult it is to control, and the more complex the control system is. First of all, the manufacturing process of the cylinder block, which is much stricter than the V8 engine. Now it is definitely one of the high-end engines.

Ferrari F12 is V12. V12 refers to the V-type 12-cylinder engine. Type V refers to the arrangement of cylinders, and 12 cylinders mean that this engine has a total of 12 cylinders. In today's society, this kind of large-displacement naturally aspirated engine is becoming rarer and rarer, which can be said to be rare.

Yes. After Lego Ferrari is installed, it can also be equipped with power group and continue to assemble and splice it, but it is not very beautiful in appearance.

How thick is the power of Lego motorcycle

1. The narrative tension of the whole play "The Legend of Zhen Yu" is not only the background of history, but also the ups and downs, heart-wrying contradictions and conflicts and emotional entanglements.

2. The power of a domestic 4-stroke motorcycle with a displacement of 125cc can reach 7KW, and the maximum horsepower is about 5PS, while the maximum power of a domestic 2-stroke motorcycle with 125cc can reach 10 kilowatts, and the horsepower is 15PS. The specific power of the motorcycle also depends on the horsepower on the manual. Quantity, and the compression ratio of the engine.

3. Lego is a very interesting and creative toy. It can create models of various shapes and functions through different combinations and assembly methods.Assembling motorcycles is also one of the very interesting and challenging activities.

4. In the inventory of the various parts of the Lego mecha. Parts are very common, and players can match the color of mecha by themselves. To combine the blocks according to this picture, pay attention to the assembly order, look at the picture clearly before starting to assemble. The helmet is not very good to assemble, and you can replace it with an ordinary motorcycle helmet.

How to assemble Lego engine + 3 cylinder

1. Follow three steps to splice. Install the engine base and box, and install the bolts, and install the engine barrel and engine cover. The crankshaft, valve, exhaust pipe, spark plug and other parts should be installed on the engine. Install the throttle valve, and finally install the electronic controller and other components in the engine compartment.

2. When I put something on its mouth, it looks at me with its big eyes open. When I watch TV, I also let it sit aside and watch some interesting cartoons, movies and horror movies with me, as if it can also understand it. When I set up Lego blocks, let it lie down. Be aside and see how I put it on.

3. Arrange the blocks in the correct order to avoid spelling mistakes or damage to the blocks. Pay attention to details and proportions to make the motorcycle look more realistic and harmonious. Be patient and careful in the assembly process, and avoid being in a hurry to succeed or careless.

The prototype of BMW anti-gravity motorcycle actually comes from Lego?

1. The method of modifying a Lego BMW motorcycle with an electric motor is as follows.Prepare some Lego materials. Install a motor on the Lego toy that is about to be assembled. Finally, connect the power supply and assemble the rest of the Legos.
