Definition and Function

The compartment transmission device is a device used in large installations such as ships and industrial equipment to transfer power between different compartments (or spaces). In ships, it is mainly used to transmit the power of the main engine to equipment in another compartment through the cabin wall, such as transferring power from the engine room to the propeller at the stern, or in some ships with special functional zones, it is used to connect equipment in different compartments to ensure the continuity of power transmission. The key to its function is to effectively transmit power while ensuring the sealing of the compartment to prevent liquid (such as seawater, oil) or gas leakage.

Structural composition

Power input components:

This is the part of the compartment transmission device that receives power, usually connected to the output shaft of the power source (such as the main engine of a ship). It can be a coupling used to connect two shafts and compensate for certain axial, radial, and angular deviations. There are various types of couplings, such as elastic couplings, which contain elastic elements that can buffer vibrations and impacts while transmitting torque; There is also a rigid coupling, which has a simple structure and is used in situations that require precise alignment and high torque.

transmission shaft:

The transmission shaft is the main component for transmitting power, which runs through the compartment wall. The transmission shaft needs to have sufficient strength and stiffness to transmit power, and its material is usually high-strength alloy steel. In order to reduce energy loss and wear during power transmission, the surface smoothness of the transmission shaft is required to be high, and special processing such as quenching, chrome plating, etc. may be applied to the parts that cooperate with other components to improve wear resistance.

Sealing components:

The sealing component is a key component of the compartment transmission device, used to prevent liquid or gas from leaking through the gap between the transmission shaft and the compartment wall. Common sealing forms include packing seals and mechanical seals. Packing seal is usually filled with soft packing (such as oil immersed asbestos rope, rubber packing, etc.) in the annular space between the transmission shaft and the compartment wall, and sealed by pressing the packing with a cover. Mechanical sealing is achieved through high-precision cooperation between the dynamic ring and the static ring. The dynamic ring rotates with the transmission shaft, while the static ring is fixed on the compartment wall. The tight fit between the two prevents leakage.

Power output components:

Located on the other side of the compartment, it outputs the power transmitted from the drive shaft to the target device (such as a propeller). It may be another coupling or a special connection structure adapted to the input shaft of the target device, such as a flower key connection, a flat key connection, etc., to ensure efficient and stable transmission of power to the target device.

working principle

When a power source (such as a ship's main engine) starts and outputs power, the power is transmitted to the drive shaft through power input components (such as couplings). The transmission shaft transfers power from one compartment through the partition wall to another compartment. During this process, sealing components play a crucial role in preventing liquid or gas leakage. For example, in the propulsion system of a ship, the power of the main engine is transmitted to the transmission shaft through the power input component of the compartment transmission device. The transmission shaft passes through the compartment wall between the engine room and the stern, and the sealing component ensures that seawater does not enter the engine room. The power is ultimately transmitted to the propeller through the power output component, causing the propeller to rotate and push the ship forward.

advantage

Effective power transmission: The compartment transmission device can effectively transmit power while ensuring the sealing of the compartment, enabling equipment in different compartments to work together. Its reasonable structural design and component selection ensure the stability and reliability of power transmission, which can meet the power requirements of large devices such as ships and industrial equipment.

Good sealing performance: By using advanced sealing technologies (such as mechanical seals) and high-quality sealing materials, the compartment transmission device can effectively prevent liquid and gas leakage. This is particularly important for equipment such as ships that work in special environments, as it can protect the interior of the equipment from external environmental erosion, while also avoiding the leakage of internal liquids (such as lubricating oil) from polluting the external environment.

Adapt to multiple working conditions: Due to the ability to choose different types of couplings, seals, and other components, the compartment transmission device can adapt to various working conditions. For example, during the navigation of a ship, it can adapt to different sea conditions, changes in engine speed and load, etc., ensuring stable power transmission and normal operation of equipment.

Disadvantages and countermeasures

Sealing components are prone to wear: Due to their constant contact with the transmission shaft during operation and the need to withstand certain pressure, sealing components are prone to wear, resulting in a decrease in sealing performance. The response measures include regular inspection of the wear of sealing components and timely replacement when the wear exceeds a certain limit. At the same time, sealing materials with better wear resistance can be used, or the sealing structure can be optimized, such as using double end mechanical seals, to improve the reliability of the seal.

High requirements for installation accuracy: The installation accuracy of the compartment transmission device has a significant impact on its performance. If the concentricity between the transmission shaft and the compartment wall is insufficient, or if the connection between the power input and output components is inaccurate, it may lead to increased vibration, accelerated component wear, and even affect power transmission. Therefore, high-precision measuring tools and installation equipment need to be used during the installation process, strictly following the installation instructions to ensure installation accuracy.

Application scenarios

Ship propulsion system: In ships, compartment transmission devices are widely used to transmit the power of the main engine to the propeller, ensuring that the propulsion power of the ship can be effectively transmitted through the bulkhead while preventing seawater from entering the engine room.

Chemical equipment: In chemical production, for equipment with different reaction or storage areas, compartment transmission devices can be used to transfer power from one area to another while ensuring sealing, such as transferring stirring power between reaction vessels with flammable, explosive, or corrosive media.
