Problems solved by technology
However, due to insufficient control of lighting accuracy, the installed rudder stock will be eccentric. At the same time, after the upper construction part, the chimney part is hoisted in place and some equipment is installed in place, the hull may be slightly deformed, which will also lead to rudder stock eccentricity. Case
The rudder stock eccentrically squeezes the rudder stock sealing ring, resulting in deformation of the sealing ring, which leads to water leakage at the rudder stock seal when the ship is under heavy load

The invention discloses a rudderstock mechanism capable of adjusting eccentricity. The rudderstock mechanism comprises a sealing base and an adjusting tool, the adjusting tool comprises a plurality offirst holes which are distributed in an annular mode and a plurality of second holes which are distributed in an annular mode. A second hole distribution circle has eccentricity and an eccentric direction relative to a first hole distribution circle. The adjusting tool is assembled and connected to a sealing base through a first hole thread, and a first hole distribution circle is coaxial with the sealing base; and a sealing seat plate is connected to the adjusting tool through a second hole in a threaded assembly mode, the second hole distribution circle is coaxial with the sealing seat plate, a cavity is formed in the axis of the sealing seat plate, and a rudder stock penetrates through the cavity. Under the condition that an original sealing base is not moved, the sealing ring and therudderstock are concentric, and water leakage caused by deformation of a sealing ring is prevented.
Description
technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a rudder stock mechanism capable of adjusting eccentricity. Background technique [0002] In the process of ship construction, since the lighting is carried out after the sub-section hoisting and assembly work below the main deck and the sub-section structural work below the aft deck are completed, the steering gear base and the rudder stock seal are usually positioned according to the lighting results. The location of the base of the device. The steering gear has been installed in place at the berth or dock stage, and the hole position of the sealing seat plate is processed according to the actual position of the rudder stock, so that the rudder stock is in the middle of the sealing seat plate to ensure a good seal of the rudder stock. However, due to insufficient control of lighting accuracy, the installed rudder stock will be eccentric. At the same time, afte...
