[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, rotating together during the transmission of motion and power, and not disengaging under normal circumstances. Sometimes it is also used as a safety device to prevent the connected components from bearing excessive loads, thus providing overload protection.

[0003] In practical applications, existing modular docking couplings for marine engines suffer from significant wear on the rubber modules due to the vibrations that accompany prolonged operations in the ship's cabin. Furthermore, ship's cabin operations require superior elastic cushioning performance. Therefore, we propose a modular docking coupling for marine engines. Utility Model Content

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a combined docking coupling for marine engines.

[0019] Combination Figures 1-4 As shown, this utility model provides a combined docking coupling for marine engines, including an active side flange 101, a driven side flange 102, and an elastic component 100 disposed between the two. The active side flange 101 and the driven side flange 102 each position the elastic component 100 through a limiting block 103 disposed thereon. The elastic component 100 is a multi-layer composite ring structure, including, from the inside out: a core matrix 110, a rubber structure composed of a base block 111 and uniformly arranged locking blocks 112 thereon; and an aramid fiber reinforced mesh 120, which is woven and embedded inside the core matrix 110. By setting a steel ring 113, a buffer steel strip 114, and an elastic steel strip 118 inside the core matrix 110, the elastic performance of the elastic component 100 can be significantly improved. At the same time, the aramid fiber reinforced mesh 120 is used to improve the overall stability and effectively improve the service life of the elastic component 100.

[0020] Furthermore, a transition bonding layer 130 is applied to the outside of the core substrate 110; an outer anti-aging cover 140 is applied to the outside of the transition bonding layer 130. Through the transition bonding layer 130 and the outer anti-aging cover 140, the wear resistance, oil resistance, heat resistance and anti-aging performance of the elastic component 100 can be greatly improved.

[0021] Specifically, a steel ring 113 is embedded in the middle of the card block 112. The steel ring 113 has a certain elasticity and a certain rigidity. It will deform when subjected to excessive external force, thus protecting the connecting shaft assembly and ensuring high safety.

[0022] Furthermore, multiple sets of buffer steel strips 114 are embedded inside the base block 111. Each end of the buffer steel strip 114 is provided with a matching slot 115 and a insert 116. The multiple sets of buffer steel strips 114 are connected together by the slot 115 and the insert 116. When the base block 111 is squeezed by external force, the buffer steel strip 114 will deform appropriately, and the insert 116 will move in the slot 115 to improve the buffering performance.

[0023] Furthermore, a rubber block 117 is placed inside the slot 115, which can be used to restrict the movement of the insert strap 116, thereby further improving the cushioning effect.

[0024] It should be noted that the transition bonding layer 130 is made of engineering plastic, which is selected from nylon, glass fiber reinforced polyamide or polyester elastomer, and the outer anti-aging cover 140 is made of hydrogenated nitrile rubber or fluororubber. Through the transition bonding layer 130 and the outer anti-aging cover 140, the wear resistance, oil resistance, heat resistance and anti-aging performance of the elastic component 100 can be greatly improved.

[0025] Furthermore, the card block 112 is also provided with an elastic steel band 118, which can further improve the elasticity of the card block 112.

[0026] The terms "fixed," "installed," "connected," "set up," "open," "equipped with," "embedded," and "covered" used in this specification to describe the position or relationship of components all indicate conventional physical connections or spatial configurations that can be understood and implemented by those skilled in the art based on the function of the relevant components, the context, and common knowledge. These relationships encompass, but are not limited to, specific forms such as welding, bonding, threaded fastening, snap-fit, interference fit, plug-in, sliding fit, hinge, integral molding, adjacent arrangement, and opening or slot accommodating. Their purpose is to clearly describe the relative positions, mating methods, and functional implementation paths between components, rather than limiting a single specific structural detail. To ensure a smooth and concise reading experience and ease of understanding, no separate explanation is provided after each term.
