High Power Marine Gearbox with PTO and PTI Functions

This technical article focuses on a high – power marine gearbox with PTO (Power Take – Off) and PTI (Power Take – In) functions. Traditional marine gearboxes have limitations, such as a lack of PTO and PTI functions, which can’t meet the diverse needs of ships. The new gearbox is composed of a hydraulically controlled clutch and gear transmission, working in conjunction with an adjustable pitch propeller. In PTO mode, the main engine drives the integrated motor for power generation, making use of residual power and enabling battery charging. In PTI mode, the shaft – driven generator gets power from the ship’s power grid for propulsion, enhancing ship maneuverability and achieving “zero” emissions. The gearbox is designed to overcome the drawbacks of traditional ones, offering advanced functions, low cost, high reliability, and high precision. It can reach six working states. The PTO and PTI clutches are arranged in series to realize different functions. With a reduction ratio range of 2:1 to 6:1 and a rated input transmission capacity of 3.448kw/rpm, it can withstand a propeller push – pull force of 450KN. This gearbox is suitable for multi – purpose work boats and ocean fishing vessels, leading the way in marine transmission with its high – efficiency, intelligent, and reliable mechatronic hybrid features.

New Breakthrough in China’s Wind Power Industry: Sliding Bearing Gearbox Localized

New Breakthrough in China’s Wind Power Industry: Sliding Bearing Gearbox Localized

In Jilin Province’s CGNPC Yuantong Sankeliu wind farm, 30 smart wind turbines have been in operation for three years, using China’s independent research and development and production of sliding bearing gearboxes, and realized “zero failure”. This is the first time that sliding bearing gearboxes have been used in the domestic wind power field in large quantities, verifying the feasibility and reliability of the technology in wind power application scenarios.
According to the relevant person in charge of the wind farm, compared with the traditional rolling bearing gearbox, the sliding bearing gearbox can reduce the power loss of about 20%-25%. This means that under the same input conditions, the power generation of a wind turbine can be increased by about 0.5%. A 3.3 MW onshore wind turbine, for example, can generate an additional 1,075,140 kWh of electricity over its entire lifecycle, which is equivalent to the annual electricity consumption of 360 households.

New Breakthrough in China’s Wind Power Industry: Sliding Bearing Gearbox Localized

New Breakthrough in China’s Wind Power Industry: Sliding Bearing Gearbox Localized

In Jilin Province’s CGNPC Yuantong Sankeliu wind farm, 30 smart wind turbines have been in operation for three years, using China’s independent research and development and production of sliding bearing gearboxes, and realized “zero failure”. This is the first time that sliding bearing gearboxes have been used in the domestic wind power field in large quantities, verifying the feasibility and reliability of the technology in wind power application scenarios.
According to the relevant person in charge of the wind farm, compared with the traditional rolling bearing gearbox, the sliding bearing gearbox can reduce the power loss of about 20%-25%. This means that under the same input conditions, the power generation of a wind turbine can be increased by about 0.5%. A 3.3 MW onshore wind turbine, for example, can generate an additional 1,075,140 kWh of electricity over its entire lifecycle, which is equivalent to the annual electricity consumption of 360 households.

New Breakthrough in China’s Wind Power Industry: Sliding Bearing Gearbox Localized

New Breakthrough in China’s Wind Power Industry: Sliding Bearing Gearbox Localized

In Jilin Province’s CGNPC Yuantong Sankeliu wind farm, 30 smart wind turbines have been in operation for three years, using China’s independent research and development and production of sliding bearing gearboxes, and realized “zero failure”. This is the first time that sliding bearing gearboxes have been used in the domestic wind power field in large quantities, verifying the feasibility and reliability of the technology in wind power application scenarios.
According to the relevant person in charge of the wind farm, compared with the traditional rolling bearing gearbox, the sliding bearing gearbox can reduce the power loss of about 20%-25%. This means that under the same input conditions, the power generation of a wind turbine can be increased by about 0.5%. A 3.3 MW onshore wind turbine, for example, can generate an additional 1,075,140 kWh of electricity over its entire lifecycle, which is equivalent to the annual electricity consumption of 360 households.

The gearbox is designed to overcome the drawbacks of traditional ones, offering advanced functions, low cost, high reliability, and high precision. It can reach six working states. The PTO and PTI clutches are arranged in series to realize different functions. With a reduction ratio range of 2:1 to 6:1 and a rated input transmission capacity of 3.448kw/rpm, it can withstand a propeller push – pull force of 450KN. This gearbox is suitable for multi – purpose work boats and ocean fishing vessels, leading the way in marine transmission with its high – efficiency, intelligent, and reliable mechatronic hybrid features.

How to Convert the CUMMINS K19-M3 Marine Engine from Dry Exhaust to Wet Exhaust?

Converting a CUMMINS K19-M3 marine engine from a dry to a wet exhaust system requires modifications to both the exhaust and cooling systems. The exhaust pipe replacement is straightforward, but the cooling system adaptation is more complex, involving thermostat removal, rocker arm disassembly, and valve clearance adjustment. Technical expertise is crucial to ensure proper reassembly and engine performance. For parts lists or expert guidance, contact our engineering team at info@seamac.com.
