Problems solved by technology
Since the outer wall of the rudder rotor, the outer wall of the rotor blade, the inner wall of the rudder hydraulic cylinder, and the inner wall of the cylinder blade are all cylindrical, they do not have the function of adjusting the axis deviation of the rudder rotor and need to be installed with a rudder bearing, especially when the rudder stock is due to various When the axis is deviated and deformed due to various reasons, it will increase the steering resistance and even damage the steering gear. At present, there is no solution or product that can easily solve this defect.

Embodiment Construction
[0027] figure 1 Among them, the rudder-pushing rotor is installed in the rudder-pushing hydraulic cylinder (the rudder-pushing rotor is not shown in the figure), and the rudder-pushing hydraulic cylinder is a split structure. The spherical body 4 adopts threaded connection and is fixedly connected to form. The rudder-pushing rotor and the rudder-pushing cylinder body 5 constitute the rudder-pushing mechanism of the rotary vane hydraulic steering gear. The support cylinder is a split structure consisting of a support cylinder body 3 and a support cylinder base 7, which are fixedly connected together by threaded connections. The inner wall of the support cylinder 3 is a concave spherical surface, and forms a spherical sliding pair with the convex spherical body 4 on the outside of the rudder hydraulic cylinder. The rudder hydraulic cylinder and the support cylinder 3 are provided with two sets of symmetrical limit mechanisms Specifically, two limit tenons 2 are symmetrically a...

The invention relates to ship equipment and particularly relates to the improvements of a self-aligning rotary blade type hydraulic steering engine for a ship. The self-aligning rotary blade type hydraulic steering engine for the ship comprises a pushing steering hydraulic cylinder for forming the rotary blade type hydraulic steering engine and a pushing steering rotor mounted in the pushing steering hydraulic cylinder; the pushing steering rotor is machined with a steering rod sleeve hole along the axis; a supporting cylinder is further arranged outside the pushing steering hydraulic cylinder; the supporting cylinder is formed by a supporting cylinder body and a supporting cylinder base; a spherical sliding pair is formed by the pushing steering hydraulic cylinder and the supporting cylinder body; and limiting mechanisms are arranged on the pushing steering hydraulic cylinder and the supporting cylinder. The self-aligning rotary blade type hydraulic steering engine for the ship not only can be adapted to axis deviation and deformation of a steering rod, but also can reduce steering resistance; and the whole force on the steering rod can be independently borne, an upper steering bearing device is saved, and the total weight and volume of a steering device are reduced.
Description
Technical field: [0001] The invention relates to marine equipment, in particular to the improvement of a marine rotary vane hydraulic steering gear. Background technique: [0002] The steering gear is the power device that controls the rotation of the ship's rudder device. It is an important equipment to ensure the safety of the ship's navigation. At present, the most advanced steering gear in the world is a spherical hydraulic steering gear. The novel structure of the "pair" is that its rudder hydraulic cylinder and the rudder rotor installed in the rudder hydraulic cylinder constitute a "spherical sliding pair", so that the rudder rotor and the fixed rudder hydraulic cylinder can be deflected, Therefore, it has the function of adjusting the axis deviation of the rudder rotor. This spherical hydraulic steering gear has a complex structure and high processing precision. At present, it is only produced by Norway TENEJORD company in the world. The torque is about 850KNM, which...
