Connecting rod action.
The main role of the connecting rod tile is to connect, support and drive the connecting rod, while reducing the friction and wear between the crankshaft and the connecting rod, withstand the huge pressure generated during the engine operation, and ensure that the crankshaft can rotate stably.
Connecting rod tile is an important part in automobile engine, they connect piston and crankshaft, convert the reciprocating movement of piston into the rotating movement of crankshaft, and transfer the force acting on the piston to the output power of crankshaft. The design of the connecting rod shingles helps to increase the lubrication effect of the oil, thereby improving the efficiency and performance of the engine. In addition, the connecting rod tiles also withstand the enormous pressure generated during the engine operation, ensuring that the crankshaft can be stable rotation. The material of the connecting rod tile is usually a combination of aluminum base and copper lead, which has good wear resistance and thermal conductivity, and can meet the needs of the engine at high load operation. In the manufacturing process of connecting rod tiles, bimetallic steel strip processing technology of steel-backed composite high tin aluminum base alloy is also used to improve its durability and reliability.
The connecting rod tile plays the role of connecting, supporting and driving in the connecting rod mechanism of the automobile, and the two ends are hinged with the active and driven members respectively to transmit motion and force. For example, in reciprocating piston power machinery and compressors, the connecting rod is used to connect the piston to the crank, converting the reciprocating motion of the piston into the rotating motion of the crank. The connecting rod is usually made of steel parts, the main part of the cross section is mostly round or I-shape, there are holes at both ends, the holes are equipped with bronze bushing or needle roller bearings, for loading the shaft pin to form an articulation.
In short, understanding and mastering the role and principle of connecting rod tiles helps us to better understand the working principle and structure of automobile engines, and improve the efficiency of automobile repair and maintenance.
Whether the connecting rod tile is large or small
tile
The connecting rod tile is a small tile. In the automobile engine, the size of the tile usually refers to the bearing tile, of which the large tile refers to the crankshaft tile, and the small tile is the connecting rod tile. Connecting rod tiles are named small tiles because they are connected to thinner connecting rod diameters. These bearings are made of high hardness wear-resistant steel, divided into upper and lower two pieces, respectively fitted in the crankshaft and cylinder body, connecting rod and crankshaft connection. The main function of the connecting rod tile is to maintain a smooth working state in the engine and contribute to the crankshaft of the engine through the sliding friction structure.
What material is connecting rod tile
The materials of connecting rod tile mainly include copper base alloy, bronze, aluminum base, white alloy (babbitt) and so on.
Copper-base alloy: The connecting rod is made of copper-base alloy material with strong bearing capacity, and the inner surface of the bearing shell is electroplated with anti-wear layer to enhance its bearing capacity and friction resistance. In addition, the wall thickness of the bearing shell adopts the tile thinning technology to make the oil film of the bearing shell more uniform during engine operation and protect the bearing shell from wear.
Bronze: The material of the connecting rod shingles includes bronze, which is a wear-resistant material used to reduce the wear between the connecting rod head and the connecting rod journal. Bronze has good wear resistance and adaptability, and can maintain stable performance in high temperature and high pressure environments.
Aluminum base: Connecting rod shingles also include the use of aluminum base materials, which have good wear resistance and adaptability to meet the high requirements of engine operation.
White alloy (Babbitt) : The outer surface of the connecting rod tile, especially the inner surface, is usually made of white alloy (a polymetallic alloy containing tin and lead). White alloy, also known as babbitt alloy, its main function is softer, lubricating and wear-resistant, which helps to reduce direct contact between metals and reduce wear.
In summary, the material selection of the connecting rod shingles is designed to provide good wear resistance, high temperature resistance and the performance of adapting to the complex operating environment of the engine.
