Abstract
The utility model discloses a ball-face sliding composite bearing with no connection joint, which aims at providing a ball-face sliding composite bearing which has the advantages of low cost and convenient manufacture and can slide on a no connection joint ball face with high speed, heavy load and precision. The ball-face sliding composite bearing is made into a hemi-spheric sleeve by sheet material of compound material through deep drawing, a through hole is arranged on the top portion of the hemi-spheric sleeve, the outer surface of the hemi-spheric sleeve is made of rolled steel, and the inner surface is a wear reduction layer. The utility model is characterized in that the surface of the hemi-spheric sleeve has no opening joint. The ball-face sliding composite bearing eliminates the shortcomings which are caused by joints which exist on the surface of the original hemi-spheric sleeve, which has the advantages of excellent lubricating property, high precision and simple manufacture process.
Description
Technical field
The utility model relates to a kind of spherical bearing, particularly a kind of jointless spherical sliding composite bearing.
Background technique
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 in some occasions.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 utility model 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.
In order to reach above-mentioned requirements, the structure of seamless spherical sliding composite bearing is: it is to make the hemisphere face cover with the sheet material of composite material through pull and stretch, 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 wall thickness of described hemisphere face cover is 1～4 millimeter.Described anti-attrition layer is that the surperficial sintering at steel has copper alloy powder, forms anti-attrition layer.Described anti-attrition layer is that the surperficial sintering at steel has spherical copper alloy powder, in the surface attachment of spherical copper alloy powder plastics is arranged, and forms anti-attrition layer.
According to said structure, the beneficial effects of the utility model are: it can eliminate the seam of original hemisphere face cover surface existence and the drawback that seam is brought.It has, and greasy property is good, precision is high, the simple advantage of manufacturing process.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.

Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Find out from Fig. 1, Fig. 2, it is to make hemisphere face cover 1 with the sheet material of composite material through pull and stretch for a seamless spherical sliding composite bearing, is shaped on through hole 2 at the top of hemisphere face cover 1, and the outer surface of hemisphere face cover 1 is steel 3, internal surface is an anti-attrition layer 4, in the surperficial imperforation seam of hemisphere face cover 1.The wall thickness of described hemisphere face cover is 1～4 millimeter, as 1 millimeter or 1.5 millimeters or 2 millimeters or 2.5 millimeters or 3 millimeters or 4 millimeters etc., determines the wall thickness that hemisphere face overlaps according to designing requirements such as the size of hemisphere face cover, applying working condition, working lifes.
The sheet material of described composite material is that the surperficial sintering at steel plate 5 has copper alloy powder 6, mainly is tin bronze powder or phosphor bronze powder, forms anti-attrition layer 4, again through being rolled into the sheet material of so-called bimetallic composite material.The sheet material of described composite material also can have spherical copper alloy powder 7 at the surperficial sintering of steel plate 5, surface attachment at spherical copper alloy powder 7 has plastics 8, its plastics 8 mainly comprise teflon or polyether-ether-ketone or polyoxymethylene, form anti-attrition layer 4, again through being rolled into the sheet material of composite material.Be processed into hemisphere face cover 1 through drawing and forming etc. again.When pull and stretch, should make the anti-attrition layer 4 of sheet material of composite material at the internal surface of hemisphere face cover 1.
Claims (4)
1, seamless spherical sliding composite bearing, it is to make the hemisphere face cover with the sheet material of composite material through pull and stretch, is shaped on through hole at the top of hemisphere face cover, and 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.
