Abstract
The invention discloses a single-slot self-lubricating oscillating bearing with an outer ring provided with composite lining plates and a manufacturing method thereof. The single-slot self-lubricating oscillating bearing has the advantages of simple structure, low cost, good self-lubricating effect and strong bearing capacity and adopts the structure that at least four steel backing composite lining plates distributed radially along the circumference are adhered on the inner surface of the outer ring. The manufacture method comprises the steps of: processing the outer ring and an inner ring by using bearing steel, wherein the outer ring is provided with an axial seam; manufacturing the at least four steel backing composite lining plates coincident with the inner surface of the outer ring in shape after being spliced radially; hacking the surface of the steel backing of each steel backing composite lining plate, grooving the surface of the steel backing and carrying out running-in on a radial splicing surface; sequentially and radially splicing the steel backing composite lining plates tightly along the circumference direction by taking the axial seam of the outer ring as an initial point and adhering on the inner surface of the outer ring, heating and solidifying an adhering agent under the condition of applying external force on an adhering surface; and directly loading the inner ring into the outer ring.
Description
Technical field:
The present invention relates to a kind of single-slot self-lubricating plain radial bearing and manufacture method, the single-slot self-lubricating knuckle bearing and the manufacture method of composite liner arranged in especially a kind of simple in structure, cost is low, self-lubricating effect good, bearing capacity is strong outer ring.
Background technique:
At present, known single-slot self-lubricating knuckle bearing all has outer ring and inner ring, inner surface cooperates with inner ring outer surface sphere, axial slit is arranged on the outer ring one, and the lubricating system of slidingsurface has following two kinds of forms usually: a kind of is that outer loop material is a Bearing Steel, is processed with blind hole at the inner ring spherical surface, be inlaid with solid lubricant in the blind hole, not only complex structure, processing bother, and because of inner ring must adopt Cuprum alloy processing, so the cost height; Another kind is that inside and outside loop material is Bearing Steel, at the direct bonding teflon braided fabric of outer ring spherical surface, though cost is relatively low, to adhesive property require high, technique for sticking is complicated and intensity is low.
The steel back composite liner plate is to be substrate with the steel plate, the mixture of lay copper powder or wire pads and copper powder thereon, behind high temperature sintering, form integrative-structure, and then at the compound one deck teflon of copper powder laminar surface (or modification) plastic layer, have that friction factor is little, wear rate is low, the intensity advantages of higher, be applied on the bearing slidingsurface.But, because the outer ring of single-slot self-lubricating knuckle bearing is the 360 degree solid of rotation that remove the place of cracking, the steel back composite liner plate that is bonded in internal surface often comes off because of the distortion of cracking of outer ring that inner ring causes is installed, for this reason, although the steel back composite liner plate has described advantage, also be not applied to single-slot self-lubricating knuckle bearing up to now.
Summary of the invention:
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, and single-slot self-lubricating knuckle bearing and manufacture method that composite liner is arranged in a kind of simple in structure, cost is low, self-lubricating effect good, bearing capacity is strong outer ring are provided.
Technical solution of the present invention is: the single-slot self-lubricating knuckle bearing that composite liner is arranged in a kind of outer ring, outer ring and inner ring are arranged, inner surface cooperates with inner ring outer surface sphere, axial slit is arranged on the outer ring one, and the internal surface of described outer ring is bonded with circumferentially radially at least four blocks of steel back composite liner plates of splicing.
Described steel back composite liner plate is composited by base steel layer, copper powder layer and polytetrafluoroethylplastic plastic layer.
The manufacture method of the single-slot self-lubricating knuckle bearing of the bonding composite liner of a kind of inner surface as mentioned above is characterized in that carrying out as follows:
A. with Bearing Steel processing outer ring and inner ring, axial slit is arranged on the outer ring one wherein;
B. make and radially splice at least four blocks of steel back composite liner plates that back and inner surface shape match;
C. with the steel backing of every block of steel back composite liner plate surface hacking and on the steel backing surface processing groove and facing-up splicing surface radially;
D. the axial slit with the outer ring is a starting point, the steel back composite liner plate is along the circumferential direction radially closely spliced in turn and is bonded on the inner surface, carries out the binder heating cure under the condition that bonding plane is applied external force;
E. inner ring is directly packed in the outer ring.
The present invention compares with prior art, has following advantage:
1. inside and outside loop material is Bearing Steel, can save a large amount of valuable non-ferrous metals (Cuprum alloy), so low cost of manufacture.
2. slidingsurface is a polytetrafluoroethylplastic plastic, and its friction factor is low, self-lubricating effect is remarkable.
3. because steel substrate directly is bonded in the inner surface of making of Bearing Steel, the steel to steel technique for sticking is simple; The stress that the structural design of at least four blocks of steel back composite liner plates can effectively be decomposed race deformation and produced, even if when inner ring is installed crack to be out of shape steel back composite liner plate obscission can not take place yet in the outer ring, steel back composite liner plate and outer ring bonding are solid and reliable, and bearing capacity is strong.
