"同步驱动皮带" can be translated as "synchronous drive belt" or "timing belt" in English.
"Synchronous drive belt" emphasizes the synchronous (or timed) nature of the belt's movement with the driving component.
"Timing belt" is a more common and colloquial term in many industries, especially in automotive and mechanical engineering contexts, where it refers to a belt that coordinates the rotation of the crankshaft and camshaft(s) in an internal combustion engine.
Both terms are correct and can be used depending on the specific context and industry.
