This utility model relates to the field of steering gear lubrication technology, specifically a high-efficiency and energy-saving steering gear transmission device for ships. It includes a steering gear body, a transmission gear set inside the steering gear body, multiple temperature detection units for detecting the internal temperature of the steering gear body, a liquid cooling unit body installed on the outside of the steering gear body, and heat dissipation pipes arranged inside the steering gear body. Coolant absorbs heat from the internal side of the steering gear body through these pipes. This utility model uses liquid cooling, preventing moisture and dust from entering the steering gear body, thus avoiding the shortened service life of the transmission gear set due to moisture and dust. The lubricating oil is heated and stirred before addition to ensure optimal lubrication. A lubrication pump delivers the lubricating oil between the gears, reducing the friction coefficient and heat generation, thus solving the high-temperature problem at its source and protecting the gears, extending their service life.
