Abstract
The following research investigates the main damages that the crankshafts from internal combustion engines may experience. Operational damage is associated with significant changes in shape, dimensions and mutual arrangement of their surfaces. Defects are classified as natural (primary) and consequential (secondary), and are caused by failures in other components that make up the engine.
