Description
Connecting rod Definition:
The connecting rod is defined as it is a mechanical component that helps to connect the piston and crankshaft of the engine. In other words, you can say it acts as an intermediate member between the piston and the cylinder.
Connecting rod Parts or Construction:
The following Construction or Parts of Connecting Rod is:
Small End
Bigger End
Bearing insert
Bushing
Bolt and nut
I-section beam
Shank
Shank:
Apart from this, both the bolt and nut acts to connect the connecting rod and cap. And we use a section beam which we call a shank. The cross-section of the rod can be rectangular, tubular, and be a circular section.
The length of the rod depends on the ratio of (l/r)
Where, l = length of the shank and r = radius of the shank.
If the length is low then the l/r ratio will also be low, Due to this, the rod will increase in angularity due to which the side thrust on the piston will increase which causes increasing linear wear.
In the same way, if the length is more then the ratio of l / k will be more. Due to this, the angularity of the rod will decrease, so due to this, the side thrust on the piston will also decrease which causes less wear is obtained in the cylinder.
Note: The higher the length, the more the engine size will also increase, so the ratio of l/r is kept between 4 and 5.
What should I do if I have a rod bearing problem?
Typically, repairing connecting rod bearings will include flushing out the engine and cooler lines, replacing the gaskets, seals, and cylinder head bolts. Read on to learn more about what rod bearings are, what causes rod bearing problems, how to fix these problems, and the cost of repairing or replacing them.
