Abstract
The utility model belongs to a sliding bearing on a steam locomotive, particularly a rocker sleeve used on the crank of the steam locomotive. The rocker sleeve is provided with a middle layer between the copper base body sleeve of the original rocker sleeve and the wear-resistant layer of the bearing alloy lining; the copper base body sleeve is changed to a steel base body sleeve, and moreover, both ends of the steel base body are provided with lining pads with stop pins according to the axial symmetry, thus, the rocker sleeve can be repeatedly used; the service life of the rocker sleeve is prolonged by 2 times; moreover, the copper consumption is reduced by 90%, and the cost is reduced by 50%.
Description
The utility model belongs to the plain bearing on the steam locomotive, particularly used linking rod sleeve on the steam locomotive crank throw.
Up to now, the linking rod sleeve that steam locomotive steam turbine portion uses as plain bearing, as shown in Figure 1, it is the sleeve of a circle, the outside of sleeve is matrix cover (1), inside face cast one deck bearing alloy lining (2) of sleeve is as anti-attrition layer, be used in shaking on the connecting rod of steam locomotive, its effect is that the transmission cylinder tractive effort becomes the plain bearing in the tractive effort at wheel rim machinery, when causing hot box to produce the bearing alloy liner melts of anti-attrition layer because of certain reason, still can continue to do the running of short time to the seizure resistance of steel axle by the matrix cover.The weak point that this linking rod sleeve exists is: one, matrix cover (1) is a cast copper matrix cover, needs copper consumption bigger during manufacturing, accounts for 90% of whole cover weight, so the cost height; Two, this linking rod sleeve can not repeated usage, and cover is as cast condition with the magnitude of interference of body of rod assembling because of this cover, and the magnitude of interference disappears when repairing extruding, and causes that to use be disposable.
The utility model provide a kind of can repeated usage, save the linking rod sleeve of the steam locomotive of copper.
For achieving the above object, the utility model is to put an interlayer between the matrix cover of original linking rod sleeve and bearing alloy lining, and is equipped with band shotpin liner at the both ends of matrix cover.
Below in conjunction with accompanying drawing the utility model is done with narration:
Accompanying drawing 1 is the structural representation of existing steam locomotive linking rod sleeve
Accompanying drawing 2 is structural representations of the present utility model
As shown in Figure 2, steam locomotive linking rod sleeve of the present utility model is the metal sleeve of a circle, this sleeve is made up of one deck bearing alloy lining (7) and the oil hole (8) of the inside face cast of exterior matrix cover (4) and sleeve, it is characterized in that between matrix cover (4) and bearing alloy lining (7), putting an interlayer (6), and be equipped with band shotpin liner (5) by axial symmetry at the two ends of matrix cover (4).
Steam locomotive linking rod sleeve of the present utility model, its matrix cover (4) is a steel material; Interlayer (6) is steel-carbon/carbon-copper composite material, is composited through high temperature, high pressure, high-revolving specified conditions, has the anchoring strength height, ability to bear is big, the characteristics of endurance, long service life, and band shotpin liner (5) can be nylon or alloy.
Steam locomotive linking rod sleeve of the present utility model, set interlayer has been selected steel-carbon/carbon-copper composite material for use, intensity and toughness have been increased, when the long-term running of steam locomotive, the bearing alloy lining weares and teares owing to axle heat and when melting, the alternative bearing alloy lining of this interlayer makes linking rod sleeve continue to play a role, and has prolonged period of service; And, increased the axial wear resisting property of linking rod sleeve at the set band shotpin liner in two ends that matrix overlaps.
The utility model Rocker sleeve of steam locomotive is mainly used on many groups driving wheel crank throw of locomotive, also can be used for replacing original cast copper cover on other plant equipment, also can be used for the tiling sliding bearing.
The utility model is compared with original linking rod sleeve, and the advantage that has is:
1, reusable, increase the service life
The linking rod sleeve intensity of original cast copper is low, poor toughness, and generally the magnitude of interference with 0.2 millimeter is pressed in the tie rod holes, need extrude when being pressed into after the reparation again, cancels because of the magnitude of interference disappears to re-use.Steam locomotive linking rod sleeve of the present utility model, the general magnitude of interference can guarantee to stipulate between the 0.04-0.08 millimeter is pressed into the pressure tonnage, when extruding, still can recover original magnitude of interference and can be pressed into use once more, when because of with turn the bearing pin diameter clearance and cross in limited time, can extrude and pour into a mould the alloy gap that resiles again and be pressed into once more, therefore reusable, mea life is minimum to prolong one times.
2, economize on copper, cost-cutting
The linking rod sleeve of this steam locomotive substitutes original tin bronze matrix cover by the steel matrix cover, can reduce copper consumption 90%, and cost of product can reduce by 50%.
