Description

[0001] The present invention relates to a universal roller,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unpaid type universal roller of a rope guide for ship berthing,

More specifically, in place of conventional metal bearings, a radial load and an axial load can be received in one direction, so that a tapered roller bearing used for high-load applications is applied, and a tapered roller bearing is mounted on a bearing housing filled with lubricant The present invention relates to a non-delivery type universal roller of a rope guide for ship berthing which can be used semi-permanently without lubrication of the lubricating oil by sealing.

In general, it is important that the ship is docked at a quay so that the ship is stably close to the quayside so that there is no collision between the ship and the quay.

In the case of a ship with a large weight, due to the weight inertia, the ship is required to berth by using the rope for berthing, as the berthing by direct operation requires considerable skill.

That is, when the ship approaches the pier within a certain distance, the rope is fixed to the rope fixing table of the wharf, the other end of the rope is fixed to the winch installed on the ship, and then the winch is operated so that the rope is wound on the winch So that the ship is gradually pulled toward the side of the pier and docked at the pier.

Here, the rope extends over the marginal portion of the ship between the rope fixture of the wharf and the winch of the ship. If the rim is directly in contact with the edge of the ship, the rope is not pulled properly due to friction. A universal roller for a rope guide is provided so that the rope can be easily pulled.

The universal roller is installed at an edge portion of the ship, and a pair of horizontal rollers spaced apart from each other by a predetermined distance are fixed to the inner side of the rear side of the fixed frame opened frontward and rearward. A pair of vertical rollers So that the rope is pierced into the center empty space between the horizontal roller and the vertical roller. When the rope is brought into contact with the rollers, the rope smoothly slides as the rollers rotate, and is easily pulled by the winch of the ship.

However, since the vertical rollers of the conventional universal roller are made of a simple cylindrical body and the ends of the cylindrical body are straight, the rope is maximized in friction between the universal rollers when the rope is positioned between the ends of the fixed rollers and rollers of the universal rollers The rope may not move properly, scratches may occur on the contact surface between the rope and the roller, or the coating of the roller may be damaged.

Thus, a registration patent utility model No. 10-0397883 (hereinafter referred to as "prior patent") has been disclosed.

1 to 3, a pair of vertical rollers 20 provided at the front portion of the front and rear open-type roller housings 10 have concave arcuate portions 21 whose ends are gradually widened at both ends, So that the rope is returned to the central portion when the rope r is moved up and down and left and right to contact the arc portion at both ends of the vertical roller 20 so that the winch can be easily pulled out of the rope, So that the durability of the roller is increased by preventing the coating of the roller from being damaged or scratching by the roller.

However, in the above-mentioned prior art, the vertical roller 20 and the unillustrated horizontal roller 30 both use a metal bearing (bush). Since such metal bearings 21 and 31 are not rolling smoothly, And the frictional force between the roller and the rope becomes large, which is an impediment to the movement of the rope.

Further, since the metal bearings 21 and 31 are not easy to be subjected to high load, there is a risk of damage if a high load is applied to the roller.

In addition, since the metal bearings 21 and 31 must continuously supply lubricating oil, there has been a problem in that a lubricating oil supply path must be formed in the rotating shaft of the roller.
