  What are the classifications of  Marine gearboxes ? There are many types of gearboxes, which can be adapted to different application scenarios. The following are some commonly used gearbox classifications. Direct rigid transmission: This transmission uses a direct rigid connection to connect the output shaft of the engine to the input shaft of the propeller. Its structure is simple and high efficiency, but it can not achieve the adjustment of speed, and can only transmit power in a fixed proportion. Yaw transmission: Yaw transmission adopts offset gear transmission, which can adjust the speed by changing the gear clearance. It is suitable for ships that need to adjust the propulsion force under different working conditions, such as tugs, barges, etc. Dual channel transmission: Dual-channel transmissions have two independent transmission channels and are generally used in dual-propeller drive systems. By controlling the speed difference between the two channels, the ship can ...

  In   Marine Engine , The Difference And Application Of Low Speed Machine And High Speed Machine? Low speed engines and high speed engines are two common engine classifications in Marine engines, and there are significant differences in their design and application. As an indispensable power source on board, Marine engine is one of the most important parts. Low-speed machines  usually use  diesel engines  as a power source, the speed range is 300-600 RPM, usually directly drive the propeller, with a larger steel material to support the weight of the rotor, so the low-speed machine is larger and heavier than the high-speed machine, but the power is greater. The design of the low-speed machine is more mature, more stable and reliable, and the low-speed machine is more energy efficient than the high-speed machine. Due to the higher efficiency and reliability of low-speed machines, they are usually used in situations that require long continuous operation and high ...
