Rudder pintle bearing body repairing process based on metal repairing agent casting

Abstract

The invention discloses a rudder pintle bearing body repairing process based on metal repairing agent casting, which comprises the following steps that: a corroded rudder pintle bearing body A is sand-blast, and then the sand-blast part of a rudder pintle bearing body is cleaned; the inner hole radius R of the sand-blast rudder pintle bearing body is measured, a new rudder pintle bearing is processed and the excircle radius thereof is R1; a feeler fixes a rudder pintle and a rudder pintle bearing C and puts the same into the rudder pintle bearing body, so that the circle of a rudder pintle bearing body C coincides with the circle of the rudder pintle; and the rudder pintle is fixed, a baffle is arranged below a gap between the rudder pintle bearing C and the rudder pintle bearing body C, metal repairing agent is cast from above the gap, the baffle, the rudder pintle and the feeler are removed after the metal repairing agent is solidified, the rudder pintle bearing C is spliced on the rudder pintle bearing body C, and the repairing of the rudder pintle bearing body A is completed. The rudder pintle bearing body repairing process based on metal repairing agent casting has the advantages of short repairing time, sailing and docking period saving, capability of achieving the same repairing effect with a borehole, no need of boring in repairing, little cost and the like.

Description

Technical field: [0001] The invention relates to the field of ship repair, in particular to a repair process for a rudder pin bearing body based on metal repair agent pouring. Background technique: [0002] During the normal navigation of the ship, corrosion will inevitably occur in the part immersed in the water surface. As an important part of the rudder system of the ship, the rudder pinion bearing body, its corrosion leads to the excessive clearance between the rudder pinion bearing body and the rudder pinion bearing, which eventually affects the The steering accuracy of the entire ship's rudder system is the key inspection object when the ship is docked for maintenance. Such as figure 1 Shown: the contact surface of rudder pintle bearing body A and rudder pintle bearing A has been immersed in water for a long time, and the contact surface of rudder pintle bearing body A is corroded, resulting in the increase of the gap between rudder pintle bearing body A and rudder pi...

AI Technical Summary

Problems solved by technology

like figure 1 Shown: the contact surface of rudder pintle bearing body A and rudder pintle bearing A has been immersed in water for a long time, and the contact surface of rudder pintle bearing body A has been corroded, resulting in the increase of the gap between rudder pintle bearing body A and rudder pin bearing A, which finally affects the Steering accuracy of the entire ship rudder system

[0003] The current repair process of the rudder pintle bearing body is to bore the rudder pintle bearing body and remove all the corroded parts of the rudder pintle bearing body. The process cycle takes 7 days, resulting in the extension of the entire shipping and docking period, and the cost is high
