高速船舶推进系统减速器

Marine gears for propulsion systems of high-speed craft

本文介绍了目前使用的各种高速船舶和它们的推进系统。并给出了对高速船舶推进系统的减速器设计有影响的参数。这里集中讨论柴油机用的船用圆柱齿轮减速箱 ,介绍了各种船用减速器的形式。首先是标准的平行轴线带倒车减速器和各种形式的输入、输出法兰 ,可看出其它结构均可从该标准结构中衍生出。本文指出各种不同的结构被用来适应各种高速船舶的不同需要。未来现代化的船用减速器设计将考虑诸如取力器、加力器和拖钓等特殊要求。

In this paper a review of the currently used types of high speed craft and the propulsion systems featured in these craft is given .The parameters are described which influence the design of marine gears for propulsion systems of high speed craft. The further explanations are then limited to marine gears with spur gear sets for drive by diesel engines. Based on the tasks of the marine gear, its different versions are described. Beginning with the standard reverse reduction gear with parallel axes and input and output flanges on different ends, it is shown how the other versions can be derived from this standard version. It is pointed out how these different versions of marine gears meet the different requirements of the various types of high speed craft. The design features of modern marine gears are looked at, followed by a description of special options such as power take off, power take in and trolling.
