What are the parts of connecting rod?

The con-rod connects the piston to the crankshaft to transfer combustion pressure to the crankpin. There are bearing portions at both ends, the piston side is called the small end, and the crankshaft side, the big end.

What causes rod bearing failure?

Lack of lubrication is the number one cause of rod bearing failure. The root cause of the issue could be anything from a low oil level to a faulty oil pump. Clogged oiling passages can also lead to isolated bearing failures.

How do you check a connecting rod bending?

One can check bend by using two pins and v block. In this method, two pins with exactly same diameter of pin bore and crank bore are used. Length of pins should be longer than the width of connecting rod and both the pins should be of same length. Connecting rod is rested on v block.

What is gudgeon pin function?

In internal combustion engines, the gudgeon pin (UK, wrist pin or piston pin US) connects the piston to the connecting rod, and provides a bearing for the connecting rod to pivot upon as the piston moves.

How connecting rod is manufactured?

Hot forged connecting rods, in particular forged connecting rods for an internal combustion engine, especially when they are made of steel, are manufactured by a process which comprises hot forging of a connecting rod rough forging, a heat treatment and a machining operation.

What is fracture split connecting rods?

The fracture splitting method is an innovative processing technique in the field of the automobile engine connecting rod (con/rod) manufacturing. Compared with traditional method, the technique has remarkable advantages. It can decrease manufacturing procedures, reduce equipment and tools investment and save energy.

What causes rods to bend?

The most common causes of a bent connecting rod are detonation or over-revving. If you know you have been driving in deep water it could have flooded your engine, leading to hydro-lock which will easily bend your connecting rods.

What is buckling of connecting rod?

Explanation: Due to the compressive load from the piston and crankshaft, the connecting rod tends to bend. This bending of the connecting rod is known as the buckling of the connecting rod.

Which rods are stronger H-beam or I-beam?

“H-beam is a stronger design when bending stress is considered,” Davis said. “H-beam rods are more difficult to machine, so they are often more expensive. I-beam rods are easier to produce and can sometimes be lighter than H-beams. All other variables being equal, H-beam rods are the strongest design.”

Is I-beam or H-beam stronger?

H-Beam and I-Beam: Projects The height of a beam is the web, which is thicker in H beams, which makes them relatively stronger than I beams. 1-beams, on the other hand, have thin webs and conical flanges.

What is crankshaft function?

The crankshaft is essentially the backbone of the internal combustion engine. The crankshaft is responsible for the proper operation of the engine and converting a linear motion to a rotational motion. Crankshafts should have very high fatigue strength and wear resistance to ensure long service life.

How to crack a connecting rod?

Apparatus and method for cracking a connecting rod comprises long and short semi-circular dies. The dies include self-contained means for biasing their flat surfaces together to enable them to be inserted through the connecting rod bore. The long die is supported on both sides of the connecting rod.

What are forged connecting rods?

Forged connecting rods are the bee’s knees when it comes to performance. Having a forged component usually makes it much more durable and resistant to wear. However, the forging process doesn’t lend itself well to mass production.

What is the purpose of connecting rod clamps?

The clamps press on bolt faces of the connecting rod to further aid in retaining the connecting rod in proper orientation relative to the supports. The connecting rod may be cracked by subjecting it to an impulsive force or to a relatively slow acting force.

What is the function of the connecting rod in an engine?

During the combustion cycle, the pistons are pushed back down into the engine, spinning the crankshaft. Connecting rods are there to provide a solid link between the crankshaft and the piston.
