The inner surface of the Ford WL curved bearing (large bearing) is processed with high precision, and the fit with the crankshaft journal is extremely high. During the manufacturing process, the inner diameter tolerance of the tile is strictly controlled to ensure a uniform and stable gap is formed between it and the crankshaft journal. This precise fitting design can effectively disperse the pressure generated during crankshaft operation, keeping the crankshaft stable during high-speed rotation, reducing vibration and wear caused by uneven clearance, and ensuring the stability of engine power transmission.
Optimized oil groove and oil hole design: The large tile surface is equipped with carefully designed oil grooves and oil holes, whose positions and shapes have been repeatedly optimized. When the engine is working, the oil enters the oil groove through the oil hole and is evenly distributed on the contact surface between the bearing and the crankshaft journal, forming a strong oil film. This oil film not only greatly reduces the friction coefficient between the two, reduces energy loss, but also serves as a buffer and shock absorber, effectively protecting the surface of the crankshaft and bearing, and extending their service life. At the same time, a reasonable oil groove design can ensure that the engine oil can be supplied to the friction parts in a timely and sufficient manner under different operating conditions of the engine, maintaining good lubrication effect.
The connecting rod bearing adopts advanced thin-walled structure design, which effectively reduces its own weight while ensuring sufficient strength and load-bearing capacity. Thin walled structures can better adapt to the complex stress conditions of connecting rods during engine operation, reduce inertial forces caused by excessive weight, and improve engine response speed and fuel economy. At the same time, the thin-walled design allows the connecting rod bearing to more tightly fit the connecting rod big end hole and the crankshaft connecting rod journal, improving the fitting accuracy and further reducing friction and wear.
High precision positioning convex points and mating surface design: The mating surface of the connecting rod bearing is precision machined to achieve extremely high standards of flatness and roughness, ensuring that the two connecting rod bearings can be tightly connected after installation, forming a good seal and support. In addition, there are high-precision positioning protrusions on the connecting rod bearing, which are precisely matched with the positioning grooves on the connecting rod big end hole. During installation, they can be quickly and accurately positioned, ensuring the concentricity between the connecting rod bearing and the connecting rod big end hole, avoiding eccentric wear and damage caused by improper installation, and ensuring the accuracy and reliability of engine power transmission.
