Everything To Know About Connecting Rod

Connecting Rod

Have any idea what is connecting rod is? It is nothing but a part of a piston engine that links the piston to the crankshaft. And it is also called a con rod. The connecting rod and the crank are responsible for converting the piston’s reciprocating motion into the crankshaft’s rotation. The connecting rod must transmit the piston’s compressive and tensile forces, which must also rotate at both ends. A mechanical linkage is the predecessor of the connecting rod and is used in water mills to change the rotational action of the water wheel into a reciprocating motion. The engine connecting rod is most frequently used in internal combustion and steam engines. Here will see everything in detail about the connecting rod:

Connecting Rod Types Utilized In Various Engine Types:

  • Plain type rod
  • Powered metal conrods
  • Fork and blade rod
  • Forged rods
  • Cast rods
  • Master and slave rod
  • Billet conrods

Parts Of Connecting Rod

  • Small End
  • Big End
  • Bushing
  • Bearing inserts
  • Bolt and Nut
  • Shank
  • Wrist pin
  • Piston
  • Bearing cap

Connecting Rod Function:

When the piston pin is pulled and pushed, it is received by the connecting rod, which then transfers the pulls and pushes to the crank pin. That is, it allows the reciprocating action of any internal combustion engine to be converted to rotational motion.

The bearings and cap are attached per the rod’s design specifications, allowing for accurate and fluid rotation. The same as a bush towards the smaller end to fit to obtain precise and fluid motion.

As a result, it is attached to a piston pin or gudgeon pin on one side. And on the opposite side is attached to the crankshaft, thus, the piston’s movement is transferred through the connecting rod to the crank.

Why Is An Excellent Connecting Rod Essential For An Engine?

1. Rotating The Crankshaft

The role of the crankshaft is to transform reciprocating motion into the rotating power required by the vehicle. The piston, which pushes and pulls this, transferring power to the crankshaft, aids in this. In one minute, the piston moves a thousand times. It must therefore function as smoothly as possible. Without the connecting rod, none of this can take place.

2. Withstanding Pressure From The Piston

One benefit is that it is a lightweight option that you will adore. The load of the piston puts a lot of strain on the engine in your vehicle. The engine heats up due to the rotational action, which raises the air temperature. The con rods are under a lot of stress throughout the combustion process. Even though they are designed to resist pressure and heat.

3. Fluid Movement

The Connecting Rod can move freely because of the movement between the crankshaft and the piston. Without them, there wouldn’t be any mechanical motion between the piston and crankshaft. You will get the best fluid movement with the use of this rod.

Applications Of Connecting Rods

The engine connecting rod is used in all types of vehicles, such as cars, trucks, and bikes. It is also used in construction vehicles like bulldozers and road rollers. In the modern era, all machines inevitably depend on pistons, connecting rods, and crankshafts.

Final Thoughts

Without a connecting rod, no engine can run at its best. The above listed are the clear details to consider about the connecting rod.
