Problems solved by technology

[0004] In addition, when assembling the conventional stern tube liner unit to the hull, the space on the rear side of the hull is reduced due to the structure in which the flange on the rear side of the liner casing protrudes toward the rear side of the stern portion of the hull. Utilization, and increase the overall length of the hull

Abstract

The present invention relates to a stern tube bush unit. When assembling the stern tube bush unit onto a hull, the rear surface of the stern of the hull and the rear surface of a first bush housing are disposed on the same plane, for coupling, and a rubber sponge is mounted between the bush housing and the hull for retaining sealing resin. Therefore, it is possible to increase the use of space at the rear side of the stern of the hull, and increase the sealing force of the resin which is filled between the hull and the bush housing. In addition, it is possible to firmly mount the stern tube bush unit at the precise position in the hull through a stable structure in a short time.

Description

technical field [0001] The present invention relates to a stern tube bushing unit installed between a propulsion shaft and a hull of a ship, in particular to improving the utilization rate of the space on the rear side of the hull and improving the sealing effect of the resin filled between the hull and the bushing unit, and The stern tube liner unit can be installed firmly and quickly with high assembly quality at the correct position in the hull to form a stable structure. Background technique [0002] In general, among various bearings supporting the propulsion shaft of a ship, a bush bearing (hereinafter referred to as a "stern tube bush unit") is used for the bearing interposed in the stern tube, and when assembling the above-mentioned stern tube When the bushing unit is used, the propeller’s own weight acting on the propulsion shaft, seawater buoyancy, thrust torque, etc. are considered to be assembled in a shaft-aligned manner so that the contact pressure with the pro...
