Description
Technical field
The invention belongs to mechanical manufacturing field, particularly to a kind of big profile shaft for cane milling or mining machinery etc.
Watt.
Background technology
Bearing is used to the mechanical organ supporting axial workpiece and making loading end catch cropping relatively slide, also referred to as sliding bearing
(Sliding Bearing), sliding bearing stable working, reliable, noiseless, it as key foundation parts at lathe, electricity
Extensive application on motivation, electromotor and internal combustion engine, especially large-scale at cane milling, rolling machinery and mining machinery etc.
In plant equipment, the parts of employing are the relatively large parts of ratio, under the conditions of hydrodynamic lubrication, and the part that axle is supported by bearing
Being referred to as axle journal, the part matched with axle journal is referred to as bearing shell, so for large-scale bearing shell, the quality of its performance directly affects
The speed of equipment, bearing capacity, functional reliability and service life.The structure of traditional large size bearing is to use stationary metal
Mould or the form of sand casting copper alloy body, later, people, in order to save the copper alloy of costliness, have invented copper alloy and steel backing run
The structure connect, further also invented and is made up of matrix and the antifriction layer be located on matrix, wherein, matrix by steel back layer and
The basal layer composition of the copper alloy being located on steel back layer, and antifriction layer typically uses Amounts of Lead, Tin Copper ternary alloy coating.But slicker solder
Copper ternary alloy coating is poor with basal layer adhesion, and fatigue resistance is low, can only achieve 100～about 140MPa.Make for a long time
With, Amounts of Lead, Tin Copper ternary alloy coating element is easily diffused into basal layer, causes this Amounts of Lead, Tin Copper ternary alloy coating composition transfer, but its
Low strength, affects bearing shell bearing capacity, and this problem annoyings the development of bearing shell industry for a long time, for this deficiency, at present
The more way is used to be: by certain method, bronze acieral to be compounded in steel substrate formation steel back aluminium bimetallic
Composite plate, to make up acieral intensity and the shortcoming of hardness deficiency, then, is cast into this steel back aluminium ply-metal
Tiles face is also welded into, then the machining carrying out bearing shell shapes.The method can well make up acieral intensity and hardness not
The shortcoming of foot, but, the method exists that follow-up machining is difficult and whole bearing shell manufacturing process complicated, high in cost of production, especially
The large axle bush that to be steel back layer be welded to each other with copper alloy layer.Therefore break through the manufacturing process technology of large axle bush, be one
Individual technical barrier urgently to be resolved hurrily.
Summary of the invention
It is an object of the invention to provide one, to have processing technique simple, rational in infrastructure, the large axle bush that durability is high.
The object of the present invention is achieved like this:
The large axle bush of the present invention, it is characterised in that: include that copper alloy face and the steel back of the body, described copper alloy face and the steel back of the body are overall knots
Configuration formula, the composition surface of described copper alloy face and the steel back of the body is provided with the staggered band Z-Correct bump mapping Z-correct structure embedded that cooperates.
The above overall structure form is to use centrifugal casting apparatus one piece casting or by being carried on the back and copper alloy by steel
Integral solder after the embedding of face.
The above band Z-Correct bump mapping Z-correct structure 3 is that the composition surface carried on the back in copper alloy face and steel is provided with at least two phase interworkings
Close the staggered fin embedded and groove with matching.
The above band Z-Correct bump mapping Z-correct structure is to be provided with at least two rows' projection or shrinkage pools on the inner surface of copper alloy face 1, with
And the steel outer surface that coordinates with copper alloy face of the back of the body is provided with corresponding cooperation and interlocks the shrinkage pool embedded and projection.
The shape of the above fin and groove is rectangle, arc, rhombus, swallow-tail form or other arbitrary shapes.
The large axle bush of the present invention provides the benefit that:
1. good product quality, intensity is high.Owing to the present invention uses the composition surface of copper alloy face and the steel back of the body to be provided with the friendship that cooperates
The wrong fin embedded and groove with matching or the projection of band Z-Correct bump mapping Z-correct structure or shrinkage pool, copper alloy face and steel back of the body phase
Snap tight against mutually, so, owing to using centrifugal casting technique, under centrifugal action, metallographic structure is tight, simultaneously because centrifugal
Power effect, does not haves tissue looseness's defect, substantially increases the adhesion strength of bearing alloy and the steel back of the body, eliminates bearing shell steel
The internal stress of dorsal body setae base, improves the fatigue strength of bearing shell.
2. durability is high, uses wide adaptability.The present invention is to use the steel back of the body to cooperate staggered embedded with copper alloy face
Band Z-Correct bump mapping Z-correct structure, be not only suitable for being cast as integrated artistic, be also suitable for by steel the back of the body and copper alloy face embed after Welder
Skill, copper alloy face is engaged closely with the steel back of the body, substantially increases the service life of bearing shell, also improve the durability of bearing shell, and make
The technique made is simply easy, and this bearing shell not only can be widely applied on lathe, motor, electromotor and internal combustion engine, the suitableeest
Conjunction is applied on the heavy mechanical equipments such as cane milling, rolling machinery and mining machinery.
