Water-lubricated bearing replacement method

The invention provides a water-lubricated bearing replacement method which is characterized in that a water-lubricated bearing is replaced under the condition that a shaft is not disassembled, and the replacement process comprises disassembly and reinstallation of the water-lubricated bearing. When the replacement method provided by the invention is used for replacing the water-lubricated bearing, the position of a shaft system can be accurately controlled, and the inner surface of the water-lubricated bearing is not damaged in the mounting process of the bearing; the epoxy resin coated on the shafting can be effectively protected, the epoxy resin is prevented from being repaired and re-coated after the construction process, and the cost and the time are saved. According to the invention, related projects such as disassembly and assembly of a rudder blade, a rudder stock, a shaft and a hydraulic coupling which are conventionally generated for replacing a water-lubricated bearing are reduced, the related relat
