Description
How is the connecting rods in Engine?
Connecting Rods
The centre connecting rod has a palm end at the lower end to which the bottom end-bearing keeps are bolted, whereas the upper end of the rod has an integral continuous lower half keep to which the upper half-bearing keeps are bolted. The side connecting rod is formed with palm ends at both ends of the rod to which the top and bottom end bearings are bolted.
The centre connecting rod top end bearings consist of continuous white metal–lined shells for the lower halves, while two bearing keeps over the ends of the crosshead pins form the upper halves.
The side connecting rod bottom end bearings are white-metal lined and are supplied with lubricating oil from the main bearings through holes passing up the connecting rods to the side top end bearings. The centre connecting rods also have cast steel white metal–lined bottom end bearings, which are supplied with oil through holes in the rods from the top end bearings. The side and centre top end bearings are fitted with white metal–lined thin-shell bearings.
The centre crosshead pins are made of nitriding steel and hardened by this process. At the top, the pins are bolted to the palm end of the piston rods with the crosshead brackets sandwiched in between; in addition, two long studs pass through the crosshead pins horizontally and secure the pins to the brackets at the back. The telescopic pipes for lubricating and cooling oils are supported by the crosshead brackets at the front of the piston rods, and the guide shoes are bolted to these brackets at the back. Each side crosshead is based on a steel casting into which the crosshead pin is shrunk, the side rod being screwed into the top of the casting.
