总结二十年来长江、内河船舶舵承结构,虽因船型及使用要求的不同而不尽相同,但大体都有规律可循。其中上舵承较为统一,只有一种型式,下舵承则因水密性要求不同,各有两种型式,图1至图5是常用的五种结构型式。由此可见,制订长江、内河船舶舵承标准是有必要也是有基础的。图1为上舵承结构。这种结构有利于拆装和检视,较受用户欢迎。图2、图3为水密结构下舵承,这种舵承结构的优点是,密封可靠,舵杆直接与舵机油缸拨叉相连,舵机则
In conclusion, the rudder bearing structure of the Yangtze River and inland river vessels in the past two decades has varied in accordance with the type of ship and the requirements for its use, but the general rules follow. One on the rudder bearing more uniform, there is only one type, the rudder bearing due to different watertight requirements, each with two types, Figure 1 to Figure 5 is a commonly used five types of structures. Thus it can be seen that it is necessary and basic to draw up the standards for the ship’s rudder bearing in the Yangtze River and inland rivers. Figure 1 on the rudder bearing structure. This structure is conducive to disassembly and inspection, more popular with users. Figure 2, Figure 3 is a watertight structure under the rudder bearing, rudder bearing structure of this advantage, reliable seal, the rudder rod directly connected with the steering gear cylinder fork, the steering gear
