The big end bearing of the connecting rod is a sliding bearing used to reduce the wear of the crankpin. According to the design differences, its structural types are divided into crosshead and non-crosshead forms [2-3]. The big end bearing of the crosshead connecting rod is usually manufactured separately and connected by the connecting rod bolt, and the inner surface is mostly directly cast with anti-friction alloy; the upper half of the big end bearing of the non-crosshead type is integrally formed with the shaft, and the lower half of the bearing cover is connected by bolts, with a bearing bush installed on the inner surface.
