The bearing solves the technical problems of insufficient design reasonability, poor self-lubricating effect and the like in the prior art. The self-lubricating bearing for the engineering machinery comprises a bearing body and is characterized in that the bearing body comprises an external carbon steel matrix and a copper alloy matrix arranged on an internal wall of the external carbon steel matrix, wherein an oil storage structure is arranged on the copper alloy matrix. Compared with the prior art, the bearing has the advantages that the bearing is more reasonable in design, simpler in structure, strong in oil storage ability, and very good in self-lubricating effect, reduces a friction coefficient, and meets a technical development trend of the current society, and the service life of the bearing is prolonged imperceptibly.
Description
Technical field
The utility model belongs to technical field of engineering machinery, especially relates to a kind of engineering machinery self oiling bearing.
Background technique
Bearing is for determining running shaft and other part relative movement positions, plays the component of supporting or leading role.It is a kind of very important component in contemporary machinery.Its major function is the supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.In order to extend the working life of bearing, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of base steel resin engineering machinery self oiling bearing [application number: 02295350.7], comprises metal-coating, and its internal surface is the hook-shaped or T word shape of sawtooth, and is inlaid with low friction, wear resistant layer.Interlayer of the present utility model has stronger combination force, for carrying in can't often refueling, middle low speed linear reciprocating motion or the machinery that rotatablely moves provides well behaved bearing; In addition, Chinese patent literature discloses a kind of engineering machinery self oiling bearing [application number: 200620106046.2], cylindrical, as to be made by the composite of the high strength of fine lubrication function, rub resistance liner, the backing made from the epoxy resin high tensile strength fibrous material glues together formation mutually.Above-mentioned two schemes has improved prior art to a certain extent, but also at least has following shortcoming: lubricant oil is easily revealed, and certainly moistens weak effect, and friction factor is large, has virtually shortened the working life of bearing.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of oil storage capacity to moisten by force and certainly effective engineering machinery self oiling bearing.
For achieving the above object, the utility model has adopted following technical proposal: this engineering machinery self oiling bearing comprises bearing body, it is characterized in that, described bearing body comprises outer plain steel and is arranged on the copper alloy matrix of outer plain steel inwall, be provided with oil-bearing structure on copper alloy matrix.Obviously, the utility model design is more reasonable, and structure is simpler, and the strong effect of certainly moistening of oil storage capacity is very good, has reduced friction factor, has virtually extended the working life of bearing, meets the development trend of current social technology.
In above-mentioned engineering machinery self oiling bearing, described oil-bearing structure comprises right-handed screw oil groove and the backpitch oil groove that is arranged on the copper alloy matrix inwall, described right-handed screw oil groove and backpitch oil groove are mutually arranged in a crossed manner, and right-handed screw oil groove and backpitch oil groove join end to end.The difficult leakage of lubricant oil and oil storage capacity are strong.
In above-mentioned engineering machinery self oiling bearing, the groove width of described right-handed screw oil groove is 0.5～3mm, and groove depth is 0.5～3mm.
In above-mentioned engineering machinery self oiling bearing, the two ends of described outer plain steel are respectively equipped with outer chamfering, at the two ends of copper alloy matrix, are respectively equipped with interior chamfering.This structure can be convenient to assembling.
In above-mentioned engineering machinery self oiling bearing, described outer plain steel and the copper alloy matrix formula that is connected as a single entity.
Compared with prior art, the advantage of this engineering machinery self oiling bearing is: it is more reasonable to design, and structure is simpler, oil storage capacity is strong very good from moistening effect, reduce friction factor, virtually extended the working life of bearing, met the development trend of current social technology.
