极压蜗轮蜗杆油
Extreme-pressure turbine worm gear oil
Standard worm gear oil is suitable for lubricating worm gear pairs operating under non‑impact loads and in humid environments, such as copper–steel transmission systems found in ships and submarines. Extreme‑pressure worm gear oil, on the other hand, is designed to handle impact loads and high pressures typical of steel‑working applications, making it ideal for lubricating worm gear sets—such as steel leadscrews with bronze nuts—as well as spur gears; it can also be used as a substitute for rolling‑mill oils.
