What is the function of bearing bush?
1 Answers
Between the small end of the connecting rod and the piston pin. The main function of the bearing bush is to provide friction protection for the connecting rod or crankshaft during high-speed operation. During engine operation, incidents of bearing seizure and shaft burning occasionally occur, mostly caused by improper bearing bush installation. Bearing seizure and burning mainly result from the rupture of the lubricating oil film between the journal and the bearing bush, leading to friction between the bearing bush and the crankshaft. Relevant introductions about the bearing bush are as follows: 1. Introduction one: In steam turbines, the bearing bush is one of the important components of the bearing, being the part of the sliding bearing that contacts the shaft. It is very smooth and usually made of wear-resistant materials such as bronze or anti-friction alloys, also known as "bushings," shaped like a semi-cylindrical tile. 2. Introduction two: Its main functions are to bear the force applied by the journal, maintain stable oil film, ensure smooth bearing operation, and reduce bearing friction loss. Bearing bushes are divided into axial thrust bushes and radial bushes. Radial bushes support the rotor and rotating parts, while thrust bushes handle axial positioning and axial thrust, serving as important stationary components.
