Abstract

The invention discloses a synchronous assembly and disassembly device for rotating and static ring components of a stern shaft sealing device. The synchronous assembly and disassembly device comprisesa threaded bushing, a support, lug rings, a screw, a pin and a gasket, and peripheral equipment comprises a rotating ring component, a static ring component, an end cap and a main shaft, wherein thesupport is formed in the way that two semi-rings are gathered and then fixed to the main shaft; the threaded bushing is axially limited by the lug rings; the screw is in threaded match with the innerhole of the threaded bushing; the lug rings are in threaded connection with the screw and the rotating ring component; a spring is mounted between the static ring component and the end cap; the pins sequentially penetrate the static ring component and the end cap; a threaded hole matched with the screw is formed in the front end of the pin; together with the threaded bushing, the screw penetratesthe gasket and then is connected with the pin; the screw is rotated to adjust the pre-tightening force between the static ring component and the end cap; and after the static ring component and the rotating ring component are in contact, the screw, the threaded bushing and the gasket are detached to finish assembly. The problem that a conventional stern shaft sealing device is difficult to mount and dismount due to pre-positioning of an electric compensation function can be solved.

Description

technical field [0001] The invention belongs to a disassembly and assembly device for a marine stern shaft seal device, in particular to a synchronous disassembly and assembly device for a dynamic ring assembly and a static ring assembly of a stern shaft seal device, which is used to meet the disassembly and assembly requirements of the stern shaft seal device after the elastic compensation function is pre-positioned . Background technique [0002] The marine stern shaft sealing device is a key sealing device to prevent outboard seawater from entering the cabin from the penetration of the stern shaft and the stern shaft hub. In the past ten years, various stern shaft sealing devices have been launched continuously. With the advantages of less leakage, long service life, and easy underwater maintenance, the outdated stuffing box seals have been gradually eliminated, and the technological progress of ship platforms has been promoted. However, because it works underwater, the ...
