Embodiment 1

[0030]The upper helm provided by this embodiment, such asFigure 1 to 3As shown, the rudder sleeve 3 and the helm body 2 are used; the rudder sleeve 3 is used to securely connect with the steering machine deck 4; the bottom of the helm body 2 has a flange, the flange projects into the rudder sleeve 3, and the flange The outer wall is fitted to the inner wall of the rudder sleeve 3; the helm body 2 is fixed to the rudder sleeve 3.

[0031]The outer wall of the flange cooperates with the inner wall of the rudder sleeve 3 to assist the helm body 2, rotate the helm body 2 to the mounting position, and secure the helm body 2 in the helm body 2 in the rudder sleeve 3 through the hex head bolt 17, easy to operate. When replacing the seal, simply take the helm body 2 to the lower length, there is no need to hang the helm body 2, the desired space is small, and the hanging rudder body 2 is removed to complete the seal replacement, It is convenient to maintain and high efficiency. Further, the up...

Embodiment 2

[0044]The rudder system provided in this embodiment includes the upper rudering provided by Example 1. The outer wall of the flange cooperates with the inner wall of the rudder sleeve 3 to assist the helm body 2, rotate the helm body 2 to the mounting position, and secure the helm body 2 in the helm body 2 in the rudder sleeve 3 through the hex head bolt 17, easy to operate. When replacing the seal, simply take the helm body 2 to the lower length, there is no need to hang the helm body 2, the desired space is small, and the hanging rudder body 2 is removed to complete the seal replacement, It is convenient to maintain and high efficiency.

Embodiment 3

[0046]The ship provided in this embodiment includes a rudder system provided by the upper rudder or Example 2 provided in Example 1. The outer wall of the flange cooperates with the inner wall of the rudder sleeve 3 to assist the helm body 2, rotate the helm body 2 to the mounting position, and secure the helm body 2 in the helm body 2 in the rudder sleeve 3 through the hex head bolt 17, easy to operate. When replacing the seal, simply take the helm body 2 to the lower length, there is no need to hang the helm body 2, the desired space is small, and the hanging rudder body 2 is removed to complete the seal replacement, It is convenient to maintain and high efficiency.

Abstract

The invention provides an upper rudder bearing, a rudder system and a ship and relates to the technical field of ships. The upper rudder bearing comprises a rudder sleeve and a rudder bearing body, wherein the rudder sleeve is used for being fixedly connected with a steering engine deck; a flange is arranged at the bottom of the rudder bearing body and extends into the rudder sleeve, and the outer wall of the flange is matched with the inner wall of the rudder sleeve; and the rudder bearing body is fixedly connected with the rudder sleeve; the outer wall of the flange is matched with the inner wall of the rudder sleeve to assist the rudder bearing body in positioning, rotating the rudder bearing body to an installation position and fixing the rudder bearing body to the rudder sleeve through the hexagon-headed bolt, installation is easy, operation is easy, when the sealing piece is replaced, only the rudder bearing body needs to be hoisted out by the sinking length, the rudder bearing body does not need to be completely hoisted out, and the needed hoisting space is small; after the rudder bearing body is hoisted out and disassembled, the sealing piece can be replaced, maintenance is convenient, and efficiency is high.

Description

Technical field[0001]The present invention relates to the field of ship technology, in particular, involving a rudder, rudder system, and a ship.Background technique[0002]The rudder system is an important equipment for changing or maintaining the direction of sailing, mainly consisting of rudder leaves, rudder rods, upper rudder and lower rudder. Among them, the upper rudder is mainly subject to the radial load caused by the power of the rudder and the axial load caused by the rudder gravity, which is an important component to ensure the safety of the rudder system.[0003]In recent years, the requirements of ship energy-saving and environmental protection have become increasing. Efficient rudders have long been able to guarantee ship maneuverability, which can improve the efficiency of advancement, especially the twisted rudder and propeller, have a good effect on improving the promotion efficiency and reducing air orifted corrosion. Therefore, the high-efficiency rudder is increasin...
