转叶式液压传动装置,特别是舵机,所以能在造船方面得到推广,因为具有下列主要特点:——能将油液压力作用下产生的势能直接转变成舵杆回转运动的机械能促使减少磨擦损失;——配置紧凑和外形尺寸不大;——结构简单、运动的另件数量少和重量轻;——在油液压力作用下,液压传动装置另件摩擦面的润滑油能减少它们的磨损;——能保证提高向一舷转舵的角度(在四个腔室构造型式时转舵角可以达到±70°);——主要由叶片和转子密封中的摩擦损失决定的机械效率足够的高(0.9～0.95);
The rotary vane hydraulics, and in particular the steering gear, are widely used in shipbuilding because of the following key features: - The ability to directly convert the potential energy generated by fluid pressure into rotary motion of the tiller causes less friction Loss; - compact configuration and small form factor; - simple structure, small number of moving parts and light weight; - under the hydraulic pressure, the oil on the friction surface of the other parts of the hydraulic actuator can reduce their Wear and tear; - it is guaranteed to increase the angle of steering to one side (the steering angle can reach up to ± 70 ° in the case of four chamber configurations); - mechanical efficiency, mainly determined by the friction losses in the blade and rotor seals, Of the high (0.9 ~ 0.95);
