Abstract
A thermometal extrusion bushing with high strength and good wear resistance comprises a steel outer sleeve and a copper alloy inner sleeve, and is characterized in that the copper alloy inner sleeve is an inner sleeve made of tin phosphorus bronze alloy; the outer sleeve and the inner sleeve can be statically or transitionally matched with each other, or are fixed by adding a screw or a positioning pin. The utility model has the advantages of good anti-fatigue performance, good elasticity, good wear resistance, high temperature resistance and strong anti-corrosion capability, and can be widely applied to the utilization of shaft sleeves in relevant situations for an automobile, a vessel, an airplane and other machineries.
Description
Technical field
The utility model relates to a kind of axle sleeve that is used for mechanical transmission, particularly relates to a kind of high and wear-resisting good again bimetal extruding lining of automobile, steamer, aircraft and all the other mechanical transmission desired strengths that is used for.
Background technique
In recent years, in the mechanical at home and abroad industry, in order to save valuable non-ferrous metal copper, guarantee high wear resistance and the low frictional factor and the strong requirement of bearing capacity of axle sleeve again, Application and Development the steel-based copper alloy dual-metal axle sleeve, this kind axle sleeve combines the high-mechanic of steel and the wear resistance of copper preferably.But existing production in the steel-based copper alloy dual-metal axle sleeve technology, because of the technology difference, the performance of product has very big difference; Usually there is (1) to adopt sintering layer of copper alloy-layer on steel plate, encloses, make the axle sleeve of band open seam through rolling, cut-out, volume; (2) adopt sintering layer of copper bisque on the integrated type steel bushing bore area, after machining, can make the high axle sleeve of precision again; (3) adopting interior clinkering one layer thickness of whole steel bushing is the copper alloy layer of 1-2 millimeter, is processed into the integrated type axle sleeve.But through the axle sleeve of above-mentioned explained hereafter owing to exist steel and Cuprum alloy combination force poor, and because of in uneven thickness, bearing capacity is strong, precision not Gao Ernan be used for highi degree of accuracy and big load be difficult to really form throughput mechanically or because of complex process, cost are high.
The model utility content
The purpose of this utility model is to provide a kind of intensity high and wear-resisting good again bimetal extruding lining.
The purpose of this utility model can reach by following technical measures, and promptly this bimetal extruding lining comprises cover in steel sleeve and the Cuprum alloy, and it is characterized in that: cover is an interior cover made from the tin-phosphor bronze alloy in the Cuprum alloy.
The tightness and the reliability that mutually combine for cover in the steel sleeve that improves and the Cuprum alloy, mode stationary fit that between the two can be by extruding or transition fit adds screw or locating stud is fixed.
In order to save Cuprum alloy to greatest extent, interior jacket wall thickness is good at 0.5-1.5mm;
When bimetal extruding lining is used for being in the occasion of high-speed motion between axle and the axle sleeve,, can on lining, establish oil groove and oilhole in order to reduce friction, to improve both working life.
According to the above-mentioned bimetal extruding lining that assembles, wear-resisting, the temperature tolerance evidence carried out through mechanical transmission National Key Laboratory of University Of Chongqing: average external volume wear rate: when lubricating grease is arranged be: 3.645 * 10
-6When cm/s, unlubricated fat be: 6.498 * 10
-6Cm/s; Grease lubrication is arranged, and the gummed load is 44kg/cm
2, no grease lubrication, the gummed load is 30kg/cm
2When oil lubrication was arranged, friction factor was 0.00965, and during oil-free lubrication, friction factor is 0.022.Above-mentioned test data shows, wear resistance of the present utility model, and particularly anti-adhesive wearing and tearing ability is better, and antiscuffing capacity is stronger, allows serviceability temperature higher, can reach 216 ℃, and PV value allowable can reach 97kgf/cm having under the grease lubrication condition
2, m/s, the PV during oil-free lubrication can reach 44kgf/cm
2, m/s.The stretching of sample being carried out through University Of Chongqing material mechanics experiment chamber again, reverse, the test shows of project such as hardness: its tension, anti-twisting property are strong, and average Brinell hardness is up to HBS170.
In sum, its anti-fatigue performance of product that the present invention makes is good, good springiness, and wear-resistant temperature-resistant degree height, corrosion resistance is strong, and the axle sleeve that can be widely used in the related occasion in automobile, boats and ships, aircraft and all the other machinery uses.

Fig. 1 is first an embodiment's of the present utility model plan view;
Fig. 2 is second an embodiment's of the present utility model plan view.
Among Fig. 1, Fig. 2: 1 is steel sleeve, and 2 is cover in the Cuprum alloy, and 3 is oilhole, and 4 is oil groove.
Embodiment
A kind of bimetal extruding of the utility model lining comprises cover 2 in steel sleeve 1 and the Cuprum alloy, and it is characterized in that: cover 2 is interior covers made from the tin-phosphor bronze alloy in the Cuprum alloy.
Referring to Fig. 1, for cover 2 tightness that mutually combines and reliabilities in the steel sleeve 1 that improves and the Cuprum alloy, the mode by transition fit connects between the two in the present embodiment.This embodiment uses as the axle sleeve of brake hub, and the wall thickness of cover 2 is at 0.5mm in the Cuprum alloy.
Referring to Fig. 2, second embodiment of the present utility model is on first embodiment's basis, has set up oil groove 4 and oilhole 3, and the axle sleeve that this embodiment is mainly used in the automobile tooth bag uses.
Claims (3)
1. a bimetal extruding lining comprises cover (2) in steel sleeve (1) and the Cuprum alloy, and it is characterized in that: cover (2) is an interior cover made from the tin-phosphor bronze alloy in the Cuprum alloy; Can connect by the mode stationary fit or transition fit of pushing or the mode that on the transition fit basis, adds screw or locating stud between the cover (2) in steel sleeve (1) and the Cuprum alloy.
2. bimetal extruding lining according to claim 1, it is characterized in that: cover (2) wall thickness is good at 0.5-1.5mm in the Cuprum alloy.
