Abstract

The utility model discloses a solid lubricating bearing with a copper-alloy graphite groove and aims at providing a solid lubricating bearing with a copper-alloy graphite groove, which is excellent in self-lubricating performance and resistant in wearing and can bear relatively large impact load. The solid lubricating bearing is a shaft sleeve made of copper alloy or hardened alloy steel, and one or more ring-shaped grooves is/are arranged on the inner surface of the shaft sleeve. The solid lubricating bearing is characterized in that each ring-shaped groove is filled with a solid lubricating agent such as graphite or molybdenum disulfide, and the surface of the solid lubricating agent is level to the inner surface of the shaft sleeve. The solid lubricating bearing disclosed by the utility model has the advantages that as the one or more ring-shaped grooves is/are arranged on the surfaces of inner holes and each groove is filled with the solid lubricating agent, in the process that the shaft sleeve does relative reciprocating or rotating movement with shafts, a solid lubricating material with which each groove is filled plays a lubrication role continuously; simultaneously, due to the design of the ring-shaped groove, the stressing of the friction surface is uniform, and the anti-impact performance of a product is improved. The solid lubricating bearing disclosed by the utility model can be widely applied to occasions of punching of mold guiding sleeves and other working conditions with reciprocating movement or rotating movement.

Description

Cuprum alloy graphite cuvette bearing with solid lubricant

Technical field

The utility model relates to a kind of sliding bearing, and relating in particular to a kind of sleeve diameter surface has the self lubrication bearing of annular solid oiling agent groove.

Background technique

Mosaic solid lubrication bearing is high because having dimensional accuracy, wear-resisting property is good, the feature that self-lubricating property is good, the positions such as mold guide sleeve are widely used in, but because its product structure is the pattern of solid lubricant inlaid after metal base surface boring, while use, easily there is the problems such as cracked on the larger large-scale punching die frame of some lateral forces.

Model utility content

The purpose of this utility model is to provide a kind of self-lubricating property excellence, wear-resistant, the Cuprum alloy graphite cuvette bearing with solid lubricant that can bear greater impact load.

In order to reach above-mentioned requirements, the technical solution of the utility model is: it is the axle sleeve made from Cuprum alloy or the alloyed steel that hardens, be shaped with one or more annular groove at the internal surface of axle sleeve, it is characterized in that being filled with in annular groove the solid lubricant of graphite or molybdenum disulfide, the surface of solid lubricant is concordant with the internal surface of axle sleeve.

Described axle sleeve is cylinder-shaped sleeve or flanged (FLGD) axle sleeve.

According to the Cuprum alloy graphite cuvette bearing with solid lubricant of such scheme design, be shaped with one or more annular groove at its bore area, in groove, be filled with graphite or molybdenum disulfide solid lubricant, make axle sleeve doing relative back and forth or in the friction process rotatablely moving with axle, allow the solid lubricant being filled in groove constantly provide lubricated, one or more ringwise trench design makes rubbing surface uniform stressed simultaneously, improve the shock resistance of product, the operating mode occasion that it can be widely used in press tool guide pin bushing and other to-and-fro motion or rotatablely move.
