The dustproof ring is assembled at the outer ends of the shaft ring and the seat ring, and a boss is arranged on the inner diameter of the dustproof ring and matched between the seat ring and the shaft ring. The utility model discloses an installation is succinct convenient, and high-efficient gyration, dustproof, oiling and the function of storing the grease have compact structure, characteristics such as bearing capacity height.

Description

Special bearing for anchor windlass of floating crane ship

Technical Field

The utility model relates to a bearing technical field, in particular to anchor windlass transmission of floating crane ship and a supporting special bearing that is used for floating crane ship anchor windlass very much.

Background

The traditional driving part of the anchor windlass is a copper sleeve, and is driven by sliding, and the bearing capacity of the copper sleeve is insufficient, so that the driving is inflexible and easy to wear and damage in advance. The traditional one-way thrust cone has four parts: the thrust tapered roller bearing with the conventional design cannot meet the requirements of industrial and mining industries.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem, provide a simple structure, the installation is succinct convenient, has one kind dustproof and that stores the grease function is used for the special bearing of floating crane ship anchor windlass.

The technical scheme is as follows:

a special bearing for a floating crane ship windlass comprises a shaft ring, a seat ring, a plurality of tapered rollers, an annular retainer and a dust ring, and is characterized in that the annular retainer is respectively provided with a plurality of roller pocket holes and is assembled between the shaft ring and the seat ring; the shaft ring and the seat ring are in the same symmetrical design, and conical raceways are respectively arranged at the corresponding ends of the shaft ring and the seat ring; the tapered rollers are respectively arranged in a plurality of roller pocket holes on the annular retainer, the tapered rollers are respectively assembled in tapered roller paths corresponding to the shaft ring and the seat ring, the rolling tapered surfaces of the tapered rollers are matched with the tapered roller paths, and a retainer seat of the annular retainer is connected with a retaining capping elastic cylindrical pin; the dust ring assembly outside the outer diameter of collar and seat circle, dust ring internal diameter direction has the boss, joins in marriage between seat circle and collar through the boss, and the dust ring is gone up and is designed the screw hole, and the dust ring plays dustproof effect, can annotate grease through the screw hole on the dust ring.

The utility model provides a technical problem be:

1. the bearing of the utility model adopts the thrust tapered roller bearing, the size and the shape of the shaft ring are completely consistent with those of the seat ring, namely the shaft ring and the seat ring realize the simple and convenient installation;

2. the utility model discloses a tapered roller way, annular holder include holder seat and holder lid, and the roller assembly is in the pocket hole of holder seat, assembles holder lid, and holder seat and holder lid are connected fixedly with the elasticity cylindric lock, and the inclined plane extension line of the tapered roller way that corresponds intersects on the centre line of gyration of bearing with the extension line of roller centre line, has avoided sliding when rotating, can guarantee that a plurality of tapered rollers realize pure rolling at the during operation, realize high-efficient gyration;

3. the utility model discloses a dust ring has realized dustproof and the function of storing the grease, and when the screw hole on the dust ring had guaranteed maintenance and maintenance, easy dismounting and the function of filling grease.
