Concentricity calibration, deviation measurement and installation method of rudder stock and rudder blade rudder pin

Abstract

The invention discloses a method for calibrating concentricity of a rudder stock, a rudder blade and a rudder pintle, measuring deviation and mounting the rudder stock and the rudder blade. The method includes steps as follows: reference objects are arranged on an upper rudder pintle sleeve and a lower rudder pintle sleeve which are well mounted, and a preset distance is reserved between a rudder stock flange connection plane and a rudder blade flange connection plane; a standard mirror is arranged in the vertical position of an axis of an end part, far away from one end of the lower rudder pintle sleeve, of the rudder stock; at least one rudder stock reference point is formed in the vertical position of the axis of the rudder pintle sleeve; and the position of the rudder stock is adjusted, so that the first reference point, a second reference point and the rudder stock reference point are located in the same straight line. After the rudder stock provided with an eccentric connection plane and the rudder blade are well mounted, the deviation of central lines can well meet requirements of China Shipbuilding Quality Standard, and the deviation delta is smaller than or equal to 0.3 mm; and particularly, when a large rudder system of the rudder stock provided with the eccentric connection plane is processed, the deviation of the central lines can well meet the quality requirements after installation.

Description

Technical field [0001] The invention relates to a ship building method, in particular to a method for calibrating the concentricity of a rudder stock and a rudder blade and a rudder pin, measuring deviation, and installing the rudder stock and a rudder blade. Background technique [0002] With the development of human marine transportation, the frequency of use of ships is getting higher and higher. For ships with cones connected to the semi-suspension rudder blade structure, the cone holes of the upper bearing seat and the lower bearing seat cone on the rudder blade are respectively connected to the rudder stock. The cone and the rudder pin cone are connected, the rudder stock and the rudder blade are respectively provided with flange connection planes, which connect the rudder stock flange connection plane and the rudder blade flange connection plane. This requires ensuring that the upper rudder pin, the lower rudder pin and the rudder stock are three The axis of the operator m...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art that the centerline deviation of the rudder stock and rudder blades is large after installation, and the center line deviation is not easy to measure and cannot be read directly after installation, and provides a rudder stock and rudder blade Concentricity calibration, deviation measurement and installation method of rudder pin
