The invention relates to a hydraulic direct-drive fin stabilizer rotating device, which comprises a block (4), a stator (5) with a blade, a fin shaft blade (6), an end face seal (7) and an end cover (8). The fin shaft blade number is usually 2_4, uniformly distributed along the circumferential direction and installed on the fin shaft (2) to withstand the oil pressure and output torque to the fin shaft and the fin fin (1) fixedly connected with the fin shaft; the stator with the blade is also uniformly distributed along the circumferential direction with an equal number of blades, and the end face seal together, the oil cavity is isolated. A high pressure cavity and a low pressure cavity are formed, and the baffle block is mounted on the fin seat (3) to balance the torque of the stator with blades. The hydraulic force acting on the fin shaft blade can directly drive the fin shaft to rotate, which solves the problem of coaxiality error caused by the sleeve of the shaft hole of the rotary blade hydraulic device on the fin shaft. Under the action of hydraulic pressure, the coaxiality between the stator with blade and the fin shaft can be guaranteed automatically, and the coaxiality error between the stator with blade and the fin shaft caused by machining and installation error, gravity, wear, vibration and other factors can be avoided. The transmission and servo control precision of the fin rotating device can be improved.
【技术实现步骤摘要】
一种液压直驱式减摇鳍转鳍装置
本专利技术涉及一种通过液压力直接驱动减摇鳍转动的装置,属于船舶及海洋工程领域。
技术介绍
减摇鳍是减小船舶横向摇摆、提高船舶稳定性的重要装置,其中,转鳍装置用于向鳍轴及与之固定连接的鳍翼输出摆动及转矩。常见的转鳍装置,通常采用传动机构将油缸等原动件的直线运动转换成往复摆动,不仅传动链长,占用空间大,而且从动件的运动(即鳍轴与鳍翼的转动)与原动件的运动(即油缸的直线运动)之间为复杂的非线性关系,增大了伺服控制难度。为此,专利“船用减摇鳍转鳍装置”(申请号:CN201220117357.4)和“船舶减摇鳍鳍角调整装置”(申请号:CN201220117357.4)提出了通过转叶式液压装置驱动鳍轴往复摆动的方案,使转鳍装置更加紧凑,减少了传动数量过多引起的非线性程度。然而,这两种方案,都需要将转叶式液压装置的轴孔套接在鳍轴上,通过孔与轴的配合传递运动及转矩,不可避免带来转叶式液压装置与鳍轴的同轴度误差,降低了传动及伺服控制精度。
技术实现思路
本专利技术的目的是进一步精简转鳍装置的传动链、提高传动及伺服控制精度,提出一种液压直驱式减摇鳍转鳍装置,将鳍轴叶片均布安装在鳍轴上,液压力作用在鳍轴叶片上即可直接驱动鳍轴及与之固定连接的鳍翼转动。具体方案如下:液压直驱式减摇鳍转鳍装置,结构包括:挡块(4)、带叶片的定子(5)、鳍轴叶片(6)、端面密封(7)、端盖(8)。所述鳍轴叶片(6)数量通常为2-4只,沿圆周方向均匀分布并固定连接在鳍轴(2)上,用以承受油压并向鳍轴及与之固定连接的鳍翼(1)输出转矩;所述带叶片的定子(5)上也沿圆周方向均匀分布 ...
