具体实施方式
在下文的描述中，给出了大量具体的细节以便提供对本发明更为彻底的理解。然而，对于本领域技术人员来说显而易见的是，本发明实施例可以无需一个或多个这些细节而得以实施。在其他的例子中，为了避免与本发明实施例发生混淆，对于本领域公知的一些技术特征未进行描述。
为了彻底了解本发明实施例，将在下列的描述中提出详细的结构。显然，本发明实施例的施行并不限定于本领域的技术人员所熟习的特殊细节。本发明的较佳实施例详细描述如下，然而除了这些详细描述外，本发明还可以具有其他实施方式。
根据本发明的一个方面，提供一种船舶柴油机推进动力模块，如附图1-4所示，该船舶柴油机推进动力模块包括以下部分：
首先是柴油机1。该柴油机1经由传动连接件连接到齿轮箱2上，从而通过齿轮箱2实现功率输出。优选地，该柴油机1为四冲程的船舶高速柴油机，当然四冲程的船舶中速柴油机也能够应用于本发明。优选地，柴油机1与齿轮箱2之间分别串有高弹性联轴器和离合器。为了确保齿轮箱2能够连接到外部负载，可选地将该齿轮箱2的输出端通过高弹性联轴器与耗功装置连接。
针对不同船舶功能和用途的需求，可以对船舶柴油机推进动力模块进行减振降噪分级。船舶柴油机推进动力模块减振降噪分级体系主要为振动分级和噪声分级，其中振动分为四级，具体来说，本发明中的减振降噪的四级分级体系包括：
第一级：为满足普通船舶对减振降噪要求一般情形的应用需求，可采用例如单层隔振的方法来降低柴油机推进动力模块的结构噪声，实现振级落差15-25dB。
第二级：为满足减振降噪要求高的区域应用需求，可采用例如单层隔振加阻尼处理或者双层隔振的方法来降低柴油机推进动力模块的结构噪声，实现振级落差25-35dB。
第三级：为满足减振降噪要求较高的区域应用需求，可采用双层隔振方法降低柴油机推进动力模块的结构噪声，实现振级落差35-45dB。
第四级：为满足减振降噪要求极高的区域应用需求，可采用例如双层隔振加阻尼处理的方法来降低柴油机推进动力模块的结构噪声，并采用隔 声设计，实现振级落差大于45dB，隔声指标为20-30dB(A)。
由此可知，为了降低船舶柴油机推进动力模块在运行过程中的振动噪音，需要设置根据本发明的用于船舶柴油机推进动力模块的减振降噪装置，其中，该减振降噪装置能够满足推进动力模块的减振降噪四级分级体系的需求。在本发明中，柴油机1采用隔振的方式布置，同时齿轮箱2采用硬弹性隔振的方式布置。作为优选的实施示例，在附图1-4中示出了根据本发明的四种示例：
