1. Basic concept of ship reducer

The reducer is a transmission mechanism, which is mainly used to slow down the engine speed and adjust the speed of the ship. The principle of the ship reducer is similar to that of a car gearbox. Through gear transmission, the high-speed rotation of the engine is converted into a low-speed rotation suitable for the movement of the ship.

2. Common ship reducers and their uses

1. Fluid coupling

The hydraulic coupling is one of the most commonly used ship reducers, with a simple structure and smooth operation. The hydraulic coupling is connected to the engine oil pump shaft, transmitting the engine power to the gear system, providing power for the entire transmission system. The hydraulic coupling is easy to operate, can be fully started in an instant, has uniform force, and has a long life. However, its disadvantages are low conversion rate and large energy loss.

2. Motor reducer

The motor reducer, also known as the DC speed regulator, is a reducer that can adjust the ship's speed as needed. The key component of the motor reducer is the planetary gear reducer, which reduces the engine's transmission efficiency through the combination of the planetary gear and the sun gear to achieve the purpose of adjusting the ship's speed. The troublesome thing about the motor reducer is that it requires special circuits and equipment for control, but its speed regulation performance and accuracy are relatively high.

3. Speed regulating gear box

The speed regulating gearbox is the main reducer used by large ships that need to reduce speed when waving flags up and down. The speed regulating gearbox converts the high-speed rotation of the engine into a low-speed rotation suitable for the movement of large ships through the matching of gears. The speed regulating gearbox has a complex structure, but it has the characteristics of high temperature resistance, wear resistance and good durability.

Conclusion

Ship reducers are an important part of ship power transmission. Different types of ships require different reducers. In order to ensure the normal operation of the ship, the selection and maintenance of ship reducers need to be completed by professional personnel.
