Abstract
The invention discloses a shaft sleeve with excellent lubrication property. The shaft sleeve is of a cylindrical shape; a transverse oil tank is formed in the inner surface of a shaft sleeve cylinder; the shaft sleeve comprises a copper alloy shaft sleeve body; the surface of an oil tank body is coated with an aluminum oxide coating; the inner surface of the shaft sleeve cylinder beyond the surface of an oil removal tank has a nickel alloy build-up welding layer; the inner surface of the shaft sleeve cylinder has an aluminum alloy build-up welding layer. The surface of the shaft sleeve oil tank body is coated with the coating to improve the corrosion resistance of the tank body; a copper-based alloy material of the invention fully meets the strength requirements of the shaft sleeve body material.
Description
Technical field
The present invention relates to the axle sleeve that a kind of lubricity is good, belongs to technical field of bearings.
Background technology
In parts at the volley, rotating shaft is installed in axis hole, because long-term use can cause between rotating shaft and axis hole
Abrasion, is generally arranged on axle sleeve countershaft in rotating shaft and shields, but rotating shaft and axle sleeve during supporting the use also
Constantly rubbing, at present, using the mode of oil addition between axle sleeve and rotating shaft to ensure to fill therebetween
The lubrication divided, extends rotating shaft and the service life of axle sleeve.Therefore, the fatigue strength of axle sleeve, wearability, intensity, hardness has the highest
Requirement, the bearing capacity of current sleeve lining is the highest, reduces the service life of axle sleeve；And processing technique is complicated, processing
Efficiency is the lowest.The deficiencies in the prior art cause axle sleeve in use, still have in-convenience in use, or self-lubrication function is not
The problem such as perfect, if safeguarding not prompt enough, then can cause axle and axle sleeve heavy wear, the problem even scrapped.
Summary of the invention
The axle sleeve that a kind of lubricity is good: cylindrically, axle sleeve cylinder inner surface offers horizontal oil groove, axle to described axle sleeve
Set includes that copper alloy shaft sleeve main body, oil groove cell body surface-coated have aluminum oxide coating layer, in the axle sleeve cylinder beyond degreasing tank surface
Surface has nickel alloy overlay cladding, and axle sleeve cylinder inner surface has aluminium alloy overlay cladding,
Copper alloy chemical composition be (percentage by weight): Cr:14.5: Si 3.5, Ni:2.5, Mn:0.85, Mo:
0.65, Nb:0.55, Ti:0.25, W:0.085, Al: 0.035, Zr:0.035, Ca 0.015, Ta:
0.015, surplus is Cu and inevitable impurity；
Manufacture described axle sleeve to comprise the following steps: according to above-mentioned copper alloy chemical composition dispensing, first fine copper is joined smelting furnace
In, Control for Kiln Temperature at 1180 DEG C, until fine copper melt after, copper melt temperature be raised to 1200 DEG C add chromium-copper intermediate alloys, after by stove
Temperature rise to 1220 DEG C adds copper silicon intermediate alloy；After furnace temperature be increased to 1240 DEG C add nickel-copper intermediate alloys；After by furnace temperature
Being increased to 1260 DEG C and add other alloying elements, rear furnace temperature is increased to 1280 DEG C, adds refine cleanser, and refine cleanser adds
Amount is the 0.9% of furnace charge amount, stirs 50 minutes, stands 100 minutes, treat that slag separates with molten metal, skim, adds coverture afterwards,
The total addition of coverture is the 0.6% of furnace charge amount, again skims after standing 40 minutes, and the most countershaft set is poured into a mould；Cast temperature
Degree is 1200 DEG C；The axle sleeve blank obtained carries out heat treatment: first carry out being heated to 750 DEG C by axle sleeve blank, and heat up speed
Rate 50 DEG C/h, is incubated 2 hours, carries out Quenching Treatment afterwards, and hardening media is water, is heated to from room temperature by axle sleeve after quenching
550 DEG C, heating rate 75 DEG C/h, be incubated 3 hours, after be cooled to 300 DEG C, rate of temperature fall 50 DEG C/h, be incubated 3 hours,
After be again cooled to 200 DEG C, rate of temperature fall 50 DEG C/h, be incubated 9 hours, rear air cooling to room temperature, described refine cleanser bag
Include: aluminum chloride 70%, calcium fluoride 10%, prodan 10%, silica 1 0%；Described coverture includes: potassium chloride 30%,
Borax 20%, sodium fluoride 20%, calcium chloride 20%, sodium chloride 10%；
