Description

What is the engine?

A high quality of crankshaft is the heart of the engine,and decide the life of engine.The combustion of fuel shoots the piston straight down the cylinder , it’s the job of the crankshaft to convert this linear motion into rotation - basically by swinging around and pushing the piston back up the cylinder.

Two type of crankshaft:

there are two types of journal on a crankshaft - the main bearing journals form the axis of rotation for the crankshaft , and the connecting rod journals are secured to the ends of the connecting rods, which run up to the pistons.

What is the design of the Engine?

Crankshafts are built using the metals like cast iron . The metal is taken in the molten form and is then poured in a mold during the process of casting whereas the modern crankshafts are made from the forged steel that is mostly used in some performance engines

The process of making a crankshaft includes heating a block of steel until it gets red hot. Once it gets hot its shape is formed using an extreme high pressure . The heat-treatment is either alloyed steel or nitride steel materials which are used . The crankshafts are also surface-hardened.

Function Of Crankshaft

There are endless functions which gives a smoother drive to the motors with the multiple cylinders.Converting the linear motion of the pistion into the rotational motion is also one amongst its functions . The power is produced through the combustion of the fuel-air mixture . The shaft of the crankshaft is bored with some holes which feeds the motor with the required quantity of oil . This oil is mainly used to smoothen the movements . Crankshafts also functions as load bearing as the load gets distributed during this process.One of the load is the severe bending and the torsional stress wherein the pistons are connected to the crankshaft through the conneting rod . It must be noted that the rotary movement of the crankshaft accelerates and decelerates constantly where the further loads of torsional vibration is added.
