2. high speed marine gearbox
This series of marine gear boxes are mainly applicable to the main propulsion drive of fixed pitch light-duty ships. There are mainly HQC series, HCV series and HCA series. The type of transmission clutch is hydraulic wet multi disc friction clutch. The operation can be pneumatic, electric or manual. The hydraulic characteristic of hydraulic oil pressure boosting function (time adjustable). The power gear is made of alloy steel and is processed by carburizing, hardening and gear grinding.
3. adjustable propeller ship gearbox
