L28/32 diesel engine parts connecting rod bushing

The connecting rod bushing is generally used for the big end, and the connecting rod bushing is generally used for the small end.

The connecting rod bearing is the middle part of the connecting rod head and the crankshaft.

The connecting rod bushing of marine diesel engine parts is the middle part where the connecting rod head and the piston pin are connected. In high-speed engines, the connecting rod bushes generally need to be plated, and the connecting rod bushings are generally not plated. Connecting rod bushings generally have no oil grooves or holes, while connecting rod bushings generally have oil grooves or oil passage bushings and bushings belong to the category of sliding bearings.

The connecting rod bearing is connected with the crank pin to reduce the wear of the crank pin and the big end bearing of the connecting rod. The big end bearing of the connecting rod is a split sliding bearing. The big end bearing of the crosshead connecting rod is often made separately, and then the connecting rod bolt is fixed to the shaft, and the anti-friction alloy is often cast directly on the inner surface. For the big end bearing without crosshead connecting rod, the upper half is often made into one body with the shaft, while the lower half of the bearing cap is manufactured separately, and then the connecting rod bolt is fixed to the upper half, and the bearing is fixed on the bearing. , The inner surface of the lower half is equipped with bearing bushes. For lubrication, oil holes are drilled in the big end bearing, and oil grooves and garbage grooves are made on the surface of the anti-friction alloy.
