Abstract

The invention mainly relates to an inverted vertical roller for a ship and belongs to the technical field of ships. The inverted vertical roller for the ship comprises a shaft, a check ring, a roller, a first bearing, a bearing seat and a second bearing, wherein the roller is sleeved outside the shaft, two ends of the shaft extend outside the roller, the check ring is arranged at the free end of the shaft, the first bearing is the single direction thrust ball bearing, the first bearing and the bearing seat are arranged between the roller and the shaft, the bearing seat is screwed on the shaft and the outer wall of the bearing seat and a gap is formed between the inner wall of the hole of the roller, and the first bearing is arranged between the end face of the bearing seat and the inner end face of the hole of the roller. After by adopting the structure, compared with the prior art, the inverted vertical roller for the ship has following advantages: possible axial direction dislocation between the roller and the shaft can be avoided after that the roller is used for a long time, the roller can roll accurately and convenience is met for practical use.

Description

technical field [0001] The invention mainly relates to a reversible vertical roller for ships, which belongs to the technical field of ships. Background technique [0002] A current marine reversible vertical roller includes a shaft, a retaining ring, a roller, two bearings and a bearing seat. The ring is arranged at the free end of the shaft, and the two ends of the roller are rotatably connected to the rotor through bearings. The above structure has the following disadvantages: after the roller has been used for a long time, there may be a certain axial misalignment between the roller and the shaft, resulting in the inability of the roller to roll accurately, which brings inconvenience to actual use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a marine reversible vertical drum that avoids certain axial misalignment between the drum and the shaft after long-term use of the drum and brings convenience to pra...
