Abstract
The invention discloses a bimetal sliding bearing and a preparation method thereof. The preparation method comprises the following steps: 1, processing a seamless steel sleeve in a corresponding specification; 2, cleaning the internal surface or the external surface of the seamless steel sleeve; 3, carrying out resurfacing welding on the internal surface or the external surface of the seamless steel sleeve through a welding stick containing tin bronze, aluminum bronze and brass to form an alloy layer; and 4, mechanically processing a bearing after resurfacing welding to meet the requirements of sizes and tolerance of the inside diameter and the outside diameter. The bimetal sliding bearing has high bearing capacity, firm adhesion of the copper alloy layer, higher finish and excellent abrasion resistance and automatic lubricity, can effectively prevent the holding-on and the wear failure of the bearing, and is particularly suitable for buffering parts and crank arm joint parts of hydraulic oil cylinders in the field of engineering machinery.
Description
Technical field
The present invention relates to a kind of bimetal sliding bearing and preparation method thereof, specifically a kind of copper base-steel bi-metal sliding bearing that forms by technique for overlaying and preparation method thereof.
Background technique
In recent years, along with the engineering machinery field technology rapid development, higher practical requirement has been proposed for the crook one's arm self-lubricating plain bearing at position of the joint of hydraulic excavator and tipper.At present, the crook one's arm self-lubricating plain bearing at position of excavator and tipper generally comprises steel pipe and is compounded in the self-lubricating layer of its inwall, and both sintering together.After using certain hour, the wear resistance of self-lubricating layer and self-lubricating property will go down very soon, can not satisfy the needed needs than high bearing capacity and low user cost of long-time running, are difficult to effectively prevent the interlock and the wear out failure of bearing.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind of bimetal sliding bearing with excellent lubricating property and advantages of good abrasion ability and preparation method thereof, thereby can satisfy the buffer locations of hydraulic jack in the engineering machinery field and the application need of the joint part of cranking arm well.
For solving the problems of the technologies described above, bimetal sliding bearing of the present invention comprises seamless steel sleeve and copper alloy layer, and described copper alloy layer is that built-up welding forms on the internal surface of described seamless steel sleeve.
The preparation method of bimetal sliding bearing, it comprises the steps: 1, processes the seamless steel sleeve of corresponding specification; 2, the internal surface or the outer surface of cleaning seamless steel sleeve; 3, utilize welding wire to carry out built-up welding, form alloy-layer at seamless steel sleeve internal surface or outer surface with tin bronze, aluminum bronze and brass composition; 4, built-up welding is good bearing carries out machining, to guarantee the size and the tolerance of internal diameter and external diameter.
The processing method of above-mentioned bimetal sliding bearing when carrying out the 2nd step, is utilized the greasy dirt of gasoline and the described seamless steel sleeve internal surface of acetone flush away, and is dabbed the surface with emery cloth, makes it to expose fresh metallic lustre.
The processing method of above-mentioned bimetal sliding bearing when carrying out the 3rd step, adopts the built-up welding of oxy-acetylene flame method, argon arc welding or plasma surfacing.
The present invention is owing to adopted technique scheme, and it is backing with the seamless steel sleeve, has very high bearing capacity, and maximum quiet bearing capacity can reach more than the 250MPa.The copper alloy layer adhesion-tight that built-up welding forms on the internal surface of seamless steel sleeve forms the higher selflubricating bimetallic bearing of degree of finish, and has higher surface hardness (HB 〉=100MPa).Bearing of the present invention has superior abrasion resistance and self lubricity, can satisfy application demand well, can effectively prevent the interlock and the wear out failure of bearing, is particularly useful for the buffer locations of hydraulic jack in the engineering machinery field and the joint part of cranking arm.
