Do You Know the Relevant Knowledge of Connecting Rod Bearings for PC58UU?

When you clicked on this article, I believe you must have come to understand connecting rod bearings for PC58UU. As a mall that sells connecting rod bearings for PC58UU, LandTopMall also has unique insights into connecting rod bearings. Next, LandTopMall will take you to understand the connecting rod bearing.

Connecting Rod Bearings for PC58UU

What are Connecting Rod Bearings for PC58UU

The connecting rod bearing for PC58UU is connected with the crankpin to reduce the wear of the crank pin. The big end bearing of the cross-head connecting rod is often made separately and then fixed with the connecting rod bolt and the rod body, which is often directly cast on its inner surface. Anti-friction alloy, big-end bearing without cross-head connecting rod, the upper half of which is often made into one piece with the shaft, while the lower half of the bearing cover is manufactured separately, and then the connecting rod bolts are used to fix the upper half. Moreover, bearing bushes are installed on the inner surfaces of the upper and lower half of the bearing. The connecting rod bearing structure has oil holes drilled on the inner surface of the shaft sleeve, and some also open oil grooves to allow lubricating oil to enter the lubrication. Self-adjusting or platform-type connecting rod small end bearings are often used.

Connecting Rod Bearings for PC58UU Lubrication Method

The lubrication method used for connecting rod bearings is pressure lubrication. Pressure lubrication: The oil pump is used to send a certain pressure of lubricating oil to the friction surface of the parts to form an oil film with a certain thickness and can withstand a certain mechanical load to achieve reliable lubrication. It mainly satisfies the lubrication of parts with high relative speed and a large mechanical load on the engine.

The Role of Connecting Rod Bearings for PC58UU

The small end bearing of the connecting rod is a small end bearing of the connecting rod that cooperates with the piston pin or the crosshead pin to reduce the wear of the pin. Usually sliding bearings.

On the crossheadless connecting rod, the small end bearing is usually made of tin bronze or lead bronze cylindrical bushing or a steel bushing with anti-friction alloy on the inner surface. Oil holes are drilled on the inner surface of the shaft sleeve, and some oil grooves are also opened to allow lubricating oil to enter and lubricate.

In order to prevent dry friction when the diesel engine is started, an oil storage tank is also formed on the inner surface of some bearings. The small end bearing of the connecting rod of a few small high-speed diesel engines adopts needle roller bearings. On the cross-head connecting rod, the small end bearing is a split sliding bearing, which is often made separately from the shaft. The anti-friction alloy is directly cast on the inner surface of the bearing, and oil grooves and oil holes are opened on the surface of the anti-friction alloy. for lubrication.

Because the small end bearing works under high pressure and swing conditions, it is more difficult to lubricate. In order to improve the reliability of lubrication, some models use a special oil pump for each cylinder to strengthen lubrication. In order to improve work reliability, self-adjusting or platform-type connecting rod small end bearings are often used.

The connecting rod’s big end bearing is matched and connected with the crankpin, which is used to reduce the wear of the crank pin. The connecting rod’s big end bearing is a split sliding bearing. The big end bearing of the cross-head connecting rod is often made separately, and then the connecting rod bolt is fixed to the rod body, and the anti-friction alloy is often directly cast on its inner surface. For big-end bearings without cross-head connecting rods, the upper half is often made into one piece with the shaft, while the lower half of the bearing cover is manufactured separately, and then connected to the upper half with connecting rod bolts. , The inner surface of the lower half is equipped with bearing bushes. For lubrication, oil holes are drilled on the big end bearing, and oil grooves and garbage grooves are opened on the surface of the anti-friction alloy.
