"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 coordinated) movement it enables between driven and driving components.
"Timing belt" is a more specific and commonly used term in mechanical engineering contexts, especially in automotive engines where it synchronizes the rotation of the crankshaft and camshaft.
Both translations are correct, and the choice between them may depend on the specific context or industry.
