Working of a Crankshaft

Aug 16,2023

The front end of a crankshaft is attached to a gear, sprocket, pulley, and vibration damper. The gear or sprocket is used to drive the camshaft. The pulley attached to the face of the crankshaft is responsible to actuate a water pump, an engine fan, or an alternator. The purpose of the vibration damper connected to a crankshaft is to attenuate the unnecessary crank twist and to suppress vibrations in the engine.

A flywheel and an oil seal is attached to the back end of the crankshaft. The flywheel helps the crankshaft exhibit rotation continuously at a constant speed, while the oil seal avoids oil spillage and leakage. To avoid further vibrations in the system, the crankshaft and flywheel are required to be balanced individually. This helps improve and maintain the machine health and reduce the risk of damage or failure of the engine.
