Timing Belt
Mechanical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A timing belt is a toothed belt that synchronizes the rotation of the crankshaft and camshaft in an internal combustion engine, or maintains precise positional alignment between two rotating shafts in machinery.
Example in context
“The timing belt must be replaced every 100,000 miles to prevent catastrophic engine valve damage.”
“Trig kayışı, motor supabında felaket hasarını önlemek için her 100.000 milde bir değiştirilmelidir.”
Where engineers use it
Timing belts are critical in automotive engines and industrial machinery requiring precise shaft synchronization. An engineer must specify replacement intervals, check tension, and ensure alignment to avoid skipped teeth or breakage.
Synonyms: synchronous belt, toothed belt
Practice: can you use “Timing Belt” at work?
A customer complains of engine misfire and rough idling. Inspection reveals a worn timing belt with missing teeth. Explain how the timing belt failure affects engine timing and what replacement procedure you would recommend.
