Marine diesel engine accessories main parts support coupling assembly

Support coupling components are mainly organic base, main bearing, body, etc. They form the skeleton of the diesel engine, support and install moving parts, combustion chamber components and various system equipment of the diesel engine.

The engine base is the diesel engine base, and the crankshaft is mounted on the engine base through the main bearing. The body, cylinder and cylinder head are all based on the frame. The engine base fastens the diesel engine to the hull base through the cushion block.

The lower part of the body and the frame together form the crankshaft rotation space, and the upper part is installed the cylinder liner and the cylinder head. Camshafts and other equipment are arranged on both sides.

The supporting parts of the connecting assembly mainly bear the action of the pneumatic force and the motion inertia force transmitted by the crank connecting rod mechanism. To ensure that the supporting and connecting parts of the mutual position is correct, management, to prevent their deformation and loosening of the connection.

The main parts of the diesel engine can also be divided into two categories of fixed parts and moving parts according to the different motion states during work. Fixed parts include cylinder head, body, frame and main bearing and other immobile main parts and their connecting fasteners. They form the fixed whole of the diesel engine. They determine the outline of the diesel engine. Their mass accounts for about 70% of the total mass of diesel engines. In order to not deform under the mechanical load such as gas force, motion inertia force and joint fastening force, and ensure correct support and lead action, they should have sufficient stiffness and strength. However, it must be small in size, light in weight and easy to operate, manage and maintain.
