Optionally, the generators can be driven secondarily or primarily depending on needs. Furthermore, solutions ensuring PTH operations are available. This requirement gains more and more importance, for instance for vessels carrying dangerous cargo.All gearboxes are equipped with an oil supply system and a monitoring system, for unattended operation, as standard. The gearboxes cover a power rating range from 1,000 to 30,000 kW for speed reducing ratios from 1.5:1 up to approx. 12:1. The propeller shaft thrust bearings are fitted into the gearbox.Accordingly,the housings are of torsionally rigid design,which also ensures perfect meshing of the gear teeth under any condition,even during bad-weather journeys.Definition of Single In Single Out Marine Gearboxes Types G U B PU (M) Vertical Offset (combined bearings)H (N) Horizontal Offset (combined bearings)B Basic DesignC Stretched DesignP With secondary or Primary PTO/H/IK With built-in multi-plate clutch,with/without PTO/H/IQ Quillshaft design, with/withoutPTO/H/I单进单出船舶齿轮箱是推进系统的重要部件，并具有各种不 同的功能，如： 将主机转速减为最佳的螺旋桨转速 用于或来自辅助驱动的PTO，PTI及PTH单进单出船舶齿轮箱应用于内河船舶、近海船舶及远洋船舶。根据需要，单进单出船舶齿轮箱结构形式可以是垂直异心、 水平异心和斜异心布置。 通常，齿轮箱带有 PTO (功率提取装置) 以提供便宜经济的电 能。根据需要，发电机驱动可以选择初级PTO或次级PTO，除 此之外PTH模式也是可行的，这种功能越来越重要，特别是在 船舶运送危险品时。作为标准配置，所有齿轮箱均带有润滑油供应系统和用于无 人操作的监控报警系统。 单进单出船舶齿轮箱功率范围从1,000 kW到30,000 kW，速 比范围从1.5:1到12:1。齿轮箱带有推力轴承可传递螺旋桨的 推力。相应的箱体采用加强设计可确保轮齿在任何条件下均 处于最佳啮合状态，即便是在恶劣的气候下航行。 单进单出船舶齿轮箱型号定义 G U B PU(M) 垂直异心 (组合轴承)H (N) 水平异心 (组合轴承)B 基本设计C 延伸设计P 带有次级或初级PTO/H/IK 带有多盘式离合器，带有/不带有PTO/H/IQ 套筒式设计，带有/不带有PTO/H/I船舶齿轮箱 Marine Gearboxes4双进单出齿轮箱 Twin In Single Out GearboxesMarine twin in single out gearboxes perform different jobs they concentrate the power of two or more diesel engines on one propeller achieve different speeds of the vessel during single input/single output or twin input/single output operation (twin-screw vessels with four engines offer still more flexibility e. g. during maintenance work on the engines） redundant propulsion systemsThe gearboxes cover a power rating range from 2 x 1,000 kW to 2 x 50,000 kW for speed reduction ratios from 2:1 up to approx. 6:1. The propeller shaft thrust bearings are fitted into the gearboxes. Advantage is frequently taken of this flexibility in the case of passenger liners such as ferry boats. PTOs are standard. In addition, primary PTOs are provided i. e. the multiple disk clutches which are fitted for connecting and disconnecting the engine are arranged in such a way that the PTO can be operated when the engine is running while the propeller is switched off. Furthermore, two-speed PTOs are used more and more to achieve still higher propulsion flexibility.Definition of Twin In Single Out Marine Gearboxes TypesG V L PA Without built-in multi-plate clutch(es)L With built-in multi-plate clutch(es)P With secondary or Primary PTO/H/IQ quillshaft design, with/without PTO/H/I双进单出船舶齿轮箱具有以下优越性： 可以集中两台或多台主机功率驱动单个螺旋桨 单机工作或双机并车工作可以获得不同的航速，（四机双 桨船有更多的灵活性，尤其在主机维护保养方面） 备用的推进系统 双进单出船舶齿轮箱功率范围从2X1,000 kW到2X50,000 kW，速比范围从2:1到6:1，并带有推力轴承。通常定期航班的船舶采用这种灵活的方式，例如快速渡船。PTO做为标准配置
