Description
Technical field
The present invention relates to a kind of spherical bearing, particularly a kind of seamless spherical sliding composite bearing and manufacture method thereof.
Background technique
Ball-joint in Machine Design can require wear resistance good usually, therefore is provided with spherical bearing in revolute pair.And the angle of yaw that the spheric roller bearing of standard or spherical ball bearing allow is too little of 2 °～3 °, and thickness is thick, can not satisfy the design and use requirement.Angle of yaw is big, bearing capacity big, the requirement of wall thickness and spherical bearing can satisfy.The spherical bearing that has the stacked composite material of two or more material of employing to make that uses in the market is a kind of novel spherical bearing.It is a sheet material of using composite material according to the specification of spherical bearing, blanking becomes the blank of long strip, again through rolling into the axle sleeve of band open seam, spherical bearing is processed in shaping again, this spherical bearing is owing to be to roll by billot to form, therefore on the surface of spherical bearing one seam is arranged, such spherical bearing is because the existence of seam, make in use lubricant film can not be continuously, dimensional accuracy can not guarantee, can only under the occasion of low speed, underloading and low precision, use, the purposes of spherical bearing is restricted.
Summary of the invention
The present invention has overcome the shortcoming that exists in the existing product, provide a kind of cheap, easily manufactured, can at a high speed, heavy duty and high-precision seamless spherical sliding composite bearing and manufacture method thereof.
In order to reach above-mentioned requirements, seamless spherical sliding composite bearing is achieved through the following technical solutions: it is the hemisphere face cover made from the sheet material of composite material, top at the hemisphere face cover is shaped on through hole, the outer surface of hemisphere face cover is steel, internal surface is an anti-attrition layer, it is characterized in that the surperficial imperforation seam of hemisphere face cover.
The sheet material of described composite material is that the surperficial sintering at steel plate has copper alloy powder, forms anti-attrition layer.
The sheet material of described composite material is that the surperficial sintering at steel plate has spherical copper alloy powder, in the surface attachment of spherical copper alloy powder plastics is arranged, and forms anti-attrition layer.Described plastics comprise teflon or polyether-ether-ketone or polyoxymethylene.
The manufacture method of above-mentioned seamless spherical sliding composite bearing may further comprise the steps:
A, according to the size of hemisphere face cover plate cutting with composite material, obtain blank;
B, through cupping tool with the blank pull and stretch, empty in the middle of making, anti-attrition layer is at the hemisphere face cover blank of internal surface;
C, go out the through hole at hemisphere face cover top or get on the bus to make the through hole at hemisphere face cover top at lathe with the punching die punching out;
D, the processing hemisphere face overlaps on lathe end face and chamfering.
Also can adopt following steps to make seamless spherical sliding composite bearing:
A, according to sheet material punching and the blanking of the size of hemisphere face cover with composite material, porose blank in the middle of obtaining, the size in hole is to be less than or equal to through hole;
B, through cupping tool with the blank pull and stretch, hemisphere face cover empty in the middle of making, anti-attrition layer has through hole at internal surface and top;
C, the processing hemisphere face overlaps on lathe end face and chamfering.
Steps A and B in above-mentioned two kinds of methods process through compound die, blanking and the pull and stretch two procedures once finishes or punching, blanking and pull and stretch three process are once finished.Also process between step B and the C through the sizing die shaping.
According to the seamless spherical sliding composite bearing that said structure and method make, just can eliminate the drawback that seam that original hemisphere face cover surface exists and seam are brought.It has, and greasy property is good, precision is high, the simple advantage of manufacturing process.This method also is applicable to other sheet materials makes jointless spherical bearing.In use, can as requested jointless spherical bearing be installed in the bearing support, adopt two involutory uses of seamless spherical sliding composite bearing, form spherical bearing, or just single only use.
