Full definition
In Mexico, "engrane" is the colloquial and widely used term for a gear (toothed wheel for power transmission), while "engranaje" is the technically correct and universally understood term throughout all Spanish-speaking countries. Mexican mechanics and plant operators universally say "engrane": "engrane de la caja" (gearbox gear), "engrane de distribucion" (timing gear), "juego de engranes" (gear set). In technical documentation, engineering drawings, and academic texts, "engranaje" is the correct form used across all of Latin America and Spain. Additional terms: "rueda dentada" (toothed wheel — generic, used in Spain), "pinon" (pinion — the smaller gear in a pair), and "corona" (ring gear/crown gear in differential or worm gear sets). For B2B content targeting Mexico: use "engranes" as the primary search term (higher search volume in MX) with "engranajes" as secondary. For pan-LATAM content: "engranajes" is the safe universal choice. Gear types in Spanish: "engranaje recto/cilindrico" (spur), "engranaje helicoidal" (helical), "engranaje conico" (bevel), "engranaje de tornillo sin fin" (worm), and "engranaje planetario" (planetary).
