<h1>Connecting Rod Shaft</h1>
The connecting rod shaft joins the piston to the crankshaft. It links the piston pin to the crankpin. Basically, it serves as a bridge between the piston and the crankshaft. The connecting rod’s one end which considered to be smaller than the other end is attached to the piston pin, while the other end which is large end, is connected to the crank pin. A long connecting rod allows a smaller and lighter piston to be used in an engine. The connecting rod's function is to transform the piston's linear motion into the crankshaft's rotating motion. The connecting rod is necessary to send the piston's compressive and tensile forces. Connecting rods are often composed of steel, although they can also be made of aluminium alloys for weight and the capacity to absorb strong effect at the cost of sturdiness. Titanium can also be used for making connecting rods, due to its lightweight and strong impact resistance. Connecting rod and piston should not be heavy they must be as lightweight as possible so as to have high generation of power and at the same time vibrations should also be lowered as the translational weight is less so in order to have proper working, they connecting rods should be kept lighter as possible. Also, it must be extremely robust and stiff, since it transmits the power surge from the piston to the crankpin. The connecting rod not only carries motion but also supplies oil for piston cooling and crosshead lubrication.
There are different types of connecting rod, they are plain type rod, fork and blade rod, master and slave rod, billet conrods, cast rods, forged rods and powered metal conrods. They are installed according to the type of engine. At every crankshaft revolution, a connecting rod is frequently exposed to enormous and repeated stresses. These generated forces are equivalent to the engine's speed. Connecting rods should be refurbished to have smooth working of engine, this is refurbishing is done normally with washing the rods, following with inspecting them for fractures with magnetic particle analysis. The rods are furthermore tested for slenderness since any bending or twisting in the rod might create oil clearance issues and eventually fail. Therefore, engine's connecting rod must be examined at frequent intervals to guarantee there are no flaws or issues and to prevent potential damages.
