CrankShaft

Crankshaft—related to crank—is a mechanical part able to perform a conversion between reciprocating motion and rotational motion.The crankshaft, sometimes casually called the crank, is the part of an engine which changes the up and down motion of the pistons into rotation. To convert the motion, the crankshaft has one or more offset shafts. The pistons are connected to the crankshaft

Description

  • A crankshaft is a fundamental feature in a vehicle’s engine. It is the system that converts linear energy into rotational energy. This enables the wheels to drive the car forward. All the pistons in the engine are attached to the crank which is also connected to the flywheel.
  • The function of the crankshaft is to translate the linear reciprocating motion of a pistons into the rotational motion required by the automobile. This is accomplished by connecting the pistons to the crank throws, which are offset from the central axis of the crankshaft to create a rotation about that axis.
