问:直接传动与间接传动有哪些特点? 答:直接传动方式突出的优点是传动效率高。主要因为:①除轴系的损失以外其他没有传动损失;②采用低速柴油机的动力装置,其螺旋桨效率较高。此外,装置简单、工作可靠、寿命长,并a维护方便、噪音小、振动小,这些就给轮机工作人员建立了良好的劳动条件,因此这种方式普遍受到轮机人员的欢迎,但是由于需采用结构上的稍复杂的可逆转的柴油机,以及由于采用低速柴油机而增加了动力装置的尺寸和重量指标,这对于排水量较小而相对功率大的渔船是比较不利的。
Q: What are the characteristics of direct drive and indirect drive? A: The direct drive has the advantage of outstanding transmission efficiency. Mainly because: ① except for the loss of shaft system, there is no transmission loss; ② low-speed diesel engine power plant, the propeller efficiency is higher. In addition, the device is simple, reliable, long life, and a convenient maintenance, noise, vibration, which gave the turbine staff to establish good working conditions, so this approach is generally welcomed by the turbine personnel, but due to be used The structurally more complex reversible diesel engines, as well as the increased size and weight indicators of the power plant due to the use of low-speed diesel engines, are less favorable for smaller displacement and relatively more powerful fishing vessels.
