Abstract

The utility model relates to a self lubrication composite liner joint bearing, which belongs to the technical field of the mechanical element. The self lubrication composite liner joint bearing is composed of an external sleeve ring (2), a tightly fixed retaining ring (1), a composite liner (3) and a spherical surface inner ring (4), wherein, the composite liner (3) of the utility model not only is the retainer of the spherical surface inner ring (4), but also is engaged with the external sleeve ring (2) to be used as one part of the external sleeve ring (2) to become a sliding pair; the composite liner (3) has the self-lubricating function.

Description

Self lubricate composite bush joint bearing

The utility model relates to a kind of mechanical component field, exactly is selflubricating composite bush joint shaft bearing.

Existing joint shaft bearing, kind is more, have plenty of 2 non-ferrous metal lining two sides are pressed into, open oilhole, constantly refuel and give to lubricate, the lasso of UC and GE class bearing will be slotted or ftracture and mouthful be put into, integral rigidity is poor, the lasso of bearing, spheroid are all used the steel manufacturing, and the friction ractor between the steel material is big, influences using effect; The lasso that has adopts nonmetallic material, in many micropores are arranged, be filled lubricant oil in the micropore, when running, be heated, lubricant oil oozes out, after the stall, lubricant oil oozes back again, this joint shaft bearing is not long working life.

The purpose of this utility model is the deficiency that will overcome in the above-mentioned technology, and it singly is not the retainer of spheroid that a kind of lining is provided, and it and outer collar are interlocked, and the part as lasso becomes sliding pair, and has the purpose of selflubricating.

The purpose of this utility model is achieved in that

A kind of selflubricating composite bush joint shaft bearing, form by outer collar, tightening back-up ring, composite bush and sphere inner ring, it is characterized in that between outer collar and the sphere inner ring composite bush being arranged, there is the tightening back-up ring on two limits of composite bush to add strong fix, and the bottom of tightening back-up ring is inserted composite bush and is connected, and the upper edge of tightening back-up ring embeds the inboard drive fit of outer collar, composite bush singly is not the retainer of sphere inner ring, it and outer collar are interlocked, and the part as outer collar becomes sliding pair.

The utility model has the advantages that one, this bearing have good mechanical properties such as heat-resisting, water-fast and wear-resisting; Its two because composite bush and outer collar are one, thereby can selflubricating and long service life; Its three, shock-resistant, noise in operating is low.

Accompanying drawing: the utility model structural representation

Embodiment:

Make outer collar (2) and sphere inner ring (4) with Bearing Steel, make tightening back-up ring (1) with metallic material, composite bush (3) is to be metal pulvis 50% by weight ratio, graphite 10%, molybdenum disulfide 10% and engineering plastics 30% mix the back sintering and form, two tightening back-up rings (1) are embedded the inboard two limit drive fits of outer collar (2), again outer collar (2) and sphere inner ring (4) are put into mould and locate, be pressed into composite bush (3), process by the known technology of bearing processing.

Claims

1, a kind of selflubricating composite bush joint shaft bearing, form by outer collar, tightening back-up ring, composite bush and sphere inner ring, it is characterized in that between outer collar (2) and the sphere inner ring (4) composite bush (3) being arranged, there is tightening back-up ring (1) on two limits of composite bush (3), the bottom of tightening back-up ring (1) is inserted composite bush (3) and is connected, and the upper edge of tightening back-up ring (1) embeds the inboard drive fit of outer collar (2).
