Marine Gearboxes

PIINC is a leading marine gear transmission manufacturer. We have developed a variety of marine gearboxes, mastered the core technology of marine gearbox design and processing, and met the personalized needs of users. According to the needs of current domestic and international market demand for marine gearboxes, we have also developed self-elevating offshore drilling platform lifting system lifting gearboxes.

The marine gearbox is the main propulsion transmission device of the ship's power system. It has the functions of reversing, clutching, reducing speed and bearing propeller thrust. It is matched with the diesel engine to form the ship's power system. It is widely used in various passenger and cargo ships, engineering ships, fishing boats, offshore and ocean-going ships, yachts, police boats, military ships, etc. It is an important key equipment in the shipbuilding industry.

Marine gearboxes are of various forms, and the common ones are reduction gearboxes, clutch reduction gearboxes, reversing and clutch reduction gearboxes, multi-speed gearboxes, multi-branch transmission gearboxes, multi-machine parallel gearboxes, and fuel-diesel combined power transmission gearboxes. According to the purpose, it can be divided into: ship main propulsion transmission and auxiliary engine transmission, ship operation machinery transmission; according to the working conditions, it can be divided into: light-load high-speed ships and medium and heavy-load ships. In terms of transmission form, there are fixed-pitch transmission gearboxes and variable-pitch transmission gearboxes; in terms of structural form, there are parallel shaft transmission and angle transmission, with the same center, horizontal different center, vertical different center, etc.
