"蜗杆传动" can be translated as "worm drive" or "worm gear drive" in English.
"Worm drive" is a commonly used term to describe the mechanism where a worm (a screw-like gear) meshes with a worm gear (a wheel-like gear) to transmit motion and power, typically with a high reduction ratio.
"Worm gear drive" is also accurate, emphasizing the involvement of the worm gear in the transmission.
Both terms are widely recognized in mechanical engineering contexts.
