Abstract
A mtehod for manufacturing the self-lubricating float bearing of turbine booster by powder metallurgy uses such alloy components as Cu-base alloy powder, graphite, MoS2 as solid lubricant and reinforcing elements including Ni and W, and includes powder metallurgy for shaping, sintering, vacuum immersion in oil and fine finishing. Said bearing features various rotation speed (even 60000-120000rpm), high self-lubricating performance and long service life. Its advantages are simple process, high productivity, and high utilization rate of raw material (up to 95%).
Description
The present invention relates to the goods of metal-powder manufacturing special shape relevant.
Turbocharging technology is the effective technical way that improves engine power, improves the environment and the saving energy, now by all kinds of vehicles widespread uses.Key part as turbo-supercharger---floating bearing, it in working order down, not only bear load, also require under 60000～120000rpm high speed rotating, have good antifriction, wear-resisting and self-lubricating property, its performance directly influences the over-all properties and the work-ing life of turbo-supercharger.The method of making this class bearing now both at home and abroad all is with ZQ
10-1The cast tin bronze antifriction metal bar that promptly contains Sn9～11% forms through mechanical workout.The self lubricity of the turbo-supercharger floating bearing that this method is produced is poor, and wearing and tearing fast particularly under moment oil-break state, sintering occurs and block or bond, and cause whole turbo-supercharger end of life; Use though this method floating bearing complete processing maturation of producing simultaneously, goods can satisfy middle and slow speed of revolution under, technical process is long, needs 18 procedures, and the material utilization ratio is low, and only about 30～35%, the cost height, production efficiency is low.
U.S 345103 discloses a kind of method of sintrered nickel bronze, its objective is the size sensitivity problem that how to solve goods in sintering process.The self-lubricating property that will solve the turbo-supercharger floating bearing with the present invention does not have dependency with the purpose of improving the material friction and wear characteristic, and both making method differences, and the component of material is also inequality.
The purpose of this invention is to provide a kind of method of producing the turbo-supercharger floating bearing, and compose friction and wear characteristic with the product excellence, make its can adapt in low gear rotating speed state use down, can satisfy again and move under the high speed rotating operating mode, overcome the sintering stuck phenomenon, improve work-ing life; Simultaneously, shorten the technological process of production, reduce materials consumption, enhance productivity.
Technical scheme of the present invention: initiative adopts powder metallurgy technology to make the method for the floating bearing that turbo-supercharger uses, it is characterized in that: at first with the copper of (weight percent) 88～82%, 5～7% tin, 5～7% zinc, 2～4% lead, after melting mixed, the copper base prealloy powder less than 0.15mm was made in spraying; Then with the copper base prealloy powder of (weight percent) 88～96%, the solid lubricant of Graphite Powder 99 1～2% and molybdenum disulphide powder 2～4%, the alloy substrate strengthening element of 2～5% nickel powders and 1～3% tungsten powder mixed after 8～12 hours, and compound is adorned mould, and control pressure is 3-5t/cm
2Compression moulding; Follow pressed compact under 810～850 ℃ temperature, logical hydrogen carries out sintering, and is incubated 1.5～3 hours; Again the agglomerating blank was sent into vacuum oil immersion 4～6 hours; Blank behind the immersion oil mould of packing into, control pressure is 3.5～8t/cm
2Carry out pressure-sizing,, can obtain qualified supercharging blower floating bearing through a small amount of following process.
Produce the method for supercharging blower bearing, its feature also is: the adding mode of alloy substrate strengthening element, can sneak into method with metal-powder machinery, and also can add treated alloying or the disperse cleaning action of reaching with the form of metal-salt.
Adopt the turbo-supercharger floating bearing of powder metallurgy technology manufacturing to compare with the turbo-supercharger floating bearing that existing machinery is processed into, the floating bearing that the present invention produces, self-lubricating property is good under the operating mode that runs up, its wear resisting property improves more than 5 times, eliminated the sintering stuck phenomenon, prolong work-ing life; The present invention is also advantageous in that the technological process of production is short, only needs eight procedures, and the production efficiency height can improve 10～12 times, and the lumber recovery height can reach more than 95%, saves the energy 30～35%, and yield rate reaches more than 95%.Production cost reduces by 40%.
Be further described in conjunction with the accompanying drawings:
Fig. 1 is technological process of production figure of the present invention.
Produce the method for self-lubricating float bearing of turbine booster as shown in Figure 1. By the proportioning choosing Get three kinds of components such as acid bronze alloy powder, kollag and matrix strengthening element, mixed in V-type Mixed 8～12 hours in glassware or other mixing equipment, various powder are fully mixed all Even, take by weighing then quantitative compound dress mould, starting pressure machine, controlled pressure are 3～5t/ Cm2Compressing, according to the needs of producing, capable of regulating pressure, the porosity of control blank; Blank is sent sintering furnace to and is carried out sintering, and logical hydrogen burns under 810～850 ℃ temperature Knot, and be incubated 1.5～3 hours; Product by sintering changed vacuum oil immersion over to 4～6 hours, Make the oil content of product moderate, guarantee under the different operating state, product has good lubricating Performance; Product behind the immersion oil mould of packing into, controlled pressure is 3.5～8t/cm2Carry out pressure-sizing, Make thus qualified floating bearing product. This floating bearing product, through the installation bench test, And tens thousand of installation uses, its combination property meets designing requirement, has satisfied turbocharging The high-speed cruising of device.
