MAXUS is connected to the bearing bush.
The main role of the automobile bearing shell is to connect, support and transfer force, while reducing friction and wear to ensure long-term engine operation.
The connecting bush, especially in the automobile engine, plays a vital role. They are mounted as plain bearings on the main shaft journal and connecting rod journal of the engine crankshaft, consisting of two semicircular sections, and are secured by shingles and bolts. The main function of the coupling is to withstand and disperse the pressure generated by the crankshaft during operation, while ensuring that the crankshaft can rotate smoothly. These bearings are usually composed of steel shingles and wear-resistant babbitt alloy, a combination of materials that ensures the durability and reliability of the bearings. The design of the bearing shell helps to increase the lubrication effect of the oil, thereby improving the efficiency and performance of the engine. In addition, the bearing bush also withstands the enormous pressure generated during the engine operation, ensuring that the crankshaft can be turned stably.
The material of the connecting bush 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 the bearing shell, the bimetallic steel strip processing technology of steel-backed composite high tin aluminum base alloy is also used to improve its durability and reliability. In the engine, the connecting bush not only bears the huge force generated by the piston movement, but also effectively transmits these forces to the crankshaft, so as to realize the transformation of the reciprocating movement of the piston to the rotating movement of the crankshaft. In addition, the connecting bush also plays the role of supporting and fixing the connecting rod to ensure that the engine can run smoothly and efficiently.
The role of the connecting bush also includes reducing the wear between the connecting rod head and the connecting rod journal. The bearing shell is generally made of thin steel back and anti-friction metal layer. The role of the thin steel back is to transfer the heat generated by the anti-friction metal to the big head of the connecting rod. The role of the anti-friction metal layer is to reduce the wear of the connecting rod journal and extend the service life of the journal. This design not only protects the key components of the engine, but also improves the overall performance and service life of the engine .
The gap direction of the connecting rod bearing bush is towards the direction of the oil pump.
In the design of the connecting rod bearing shell, the gap is in the direction of the oil pump, mainly to ensure that the lubricating oil can flow smoothly to the connection part of the connecting rod tile and the crankshaft when the engine is running, thus providing the necessary lubrication effect. This design has an effective lubrication effect on the connecting rod of the engine, and the connecting rod bearing shell is divided into two parts of the upper and lower tiles, which are installed at the connection of the connecting rod and the crankshaft, and play the role of wear resistance, support and transmission. When assembling connecting rod watts, it is necessary to pay attention to the direction, otherwise it will lead to different degrees of impact. If the inner cylinder of the upper tile of the connecting rod is provided with an oil groove of reasonable arc length along the circumference, and the wall of the connecting rod tile of the oil groove is provided with an oil hole, that is, the notch mentioned in this paper, then the assembly can be carried out by locating the position of the lip. If there is no locating lip, it can be used on a connecting rod with locating lip, but not vice versa. In addition, the screw should reach the corresponding torque, but not too tight, otherwise it will lead to excessive force on the bolt, internal thread slip and bolt deformation .
