Vynález sa týká spósobu výroby združeného bimetalického pásu pre kízne ložiská s klznou vrstvou zo zliatiny hliníka s kremíkom, ktoré obsahuje 8 až 15 % Si, 0,05 až 0,2 % Mn, 0,05 až 0,2 % Cr, 0,05 až 0,2 % Fe, 0,3 až 0,6 °/q Cu a v ktorej súčet obsahov Fe, Mn a Cr nepřevýší obsah Cu.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for the production of a composite bimetallic belt for sliding bearings with an aluminum-silicon sliding layer comprising 8 to 15% Si, 0.05 to 0.2% Mn, 0.05 to 0.2% Cr, O, 05 to 0.2% Fe, 0.3 to 0.6 ° / q Cu and in which the sum of the contents of Fe, Mn and Cr does not exceed the content of Cu.
V súčasnosti sa v dieselových motoroch používajú ložiská s klznou vrstvou z olovených bronzov. Vývoj týchto motorov, predovšetkým preplňovanie dieselových motorov, prináša so sebou vzrost maximálnych tlakov olejového filmu v ložiskách, čo vyžaduje ložiskový materiál s vysokou pevnosťou pri zachovaní dobrých kíznych vlastností. Týmto vysokým nárokom už v súčasnosti používané olovené bronzy svojimi vlastnosťami nevyhovujú.Nowadays, bearings with lead bronze plain bearing are used in diesel engines. The development of these engines, in particular the turbocharging of diesel engines, entails an increase in the maximum oil film pressures in the bearings, requiring high strength bearing material while maintaining good grip properties. The lead bronzes used today do not satisfy these high demands.
Vyššie uvedené nedostatky odstraňuje spósob výroby združeného bimetalického pásu pre kízne ložiská s klznou vrstvou zo zliatiny hliníka s kremíkom, ktorá obsahuje 8 až 15 % Si, 0,05 až 0,2 % Mn, 0,05 až 0,2 % Cr, 0,05 až 0,2 % Fe a 0,3 až 0,6 % Cu tak, že súčet obsahov Fe, Cr a Mn nepřevýší obsah médi podía vynálezu, ktorého podstata spočívá v tom, že doškový polotovar z uvedenej zliatiny sa válcuje pri teplote 480 až 510 °C úbermi, obyčajne v rozmedzí 20 až 30 % tak, že sa získá pás o hrúbke v závislosti od typu ložiska (4 až 9 mm). Takto vyrobený pás sa odmastí a jednostranné zdrsní. Rovnako sa odmastí a jednostranné zdrsní hliníková folia o hrúbke podía typu ložiska (0,3 až 0,8 mm). Takto upravené pásy sa valcujú spolu pri teplote 480 až 510 °C úbermi 15 až 45 %. Takto sa získá združený pás, ktorého hrúbka v závislosti od typu ložiska je obvykle v rozmedzí 0,8 až 3 mm. Združený pás sa odmastí a zdrsní na pohliníkovanej straně a združí sa válcováním jedným úberom pri teplote 380 až 420°C s odmaštěným a jednostranné zdrsněným oceíovým pásom. V závislosti od typu ložiska je hrúbka konečného bimetalického pásu obyčajne 1,5 až 4 mm. Z takto získaného bimetalického pásu sa vyrábajú ložiská běžnou technológiou.The above-mentioned drawbacks are eliminated by a method of manufacturing a composite bimetallic belt for sliding bearings with a sliding layer of aluminum-silicon alloy containing 8 to 15% Si, 0.05 to 0.2% Mn, 0.05 to 0.2% Cr, O , 05 to 0.2% Fe and 0.3 to 0.6% Cu such that the sum of the contents of Fe, Cr and Mn does not exceed the content of the medium according to the invention, which consists in that the thatched blank of said alloy is rolled at a temperature 480-510 ° C by stripping, usually in the range of 20-30%, so as to obtain a strip of thickness depending on the type of bearing (4-9 mm). The belt thus produced is degreased and roughened on one side. It is also degreased and a one-sided rough aluminum foil with a thickness according to the bearing type (0.3 to 0.8 mm). The treated strips are rolled together at a temperature of 480-510 ° C by removing 15-45%. A composite strip is thus obtained, the thickness of which, depending on the type of bearing, is usually in the range 0.8 to 3 mm. The composite strip is degreased and roughened on the aluminized side and composite by rolling with a single strip at a temperature of 380 to 420 ° C with a degreased and one-sided roughened steel strip. Depending on the type of bearing, the thickness of the final bimetallic strip is usually 1.5 to 4 mm. The bimetallic strip thus obtained is used to produce bearings by conventional technology.
Združené bimetalické pásy s klznou vrstvou zo zliatiny hliníka s kremíkom, méďou, chrómom, mangánom a železom je možné použit do klzných uložení s vysokým měrným zatažením, čo je typický případ dieselových motorov. Ložiskové púzdra z tohto materiálu tiež nájdu uplatnenie v automobilových benzínových motoroch, pracujúcich pri nižších otáčkách a vyššom dynamickom zatažení a v iných točivých strojoch s obdobným namáháním kíznych uložení. Vysoká odolnost’ proti jednotlivým vplyvom, ktorým je ložisko vystavené, a nízkou výrobnou cenou v porovnaní s olovenými bronzmi je táto náhrada i ekonomicky výhodná.Composite bimetallic belts with aluminum alloy silicon, copper, chrome, manganese and iron sliding layers can be used in high specific load sliding bearings, a typical case of diesel engines. Bearing housings of this material will also find application in automotive gasoline engines operating at lower speeds and higher dynamic loads, and in other rotating machines with similar stress on the slide bearings. The high resistance 'to the individual influences to which the bearing is subjected and the low production price compared to lead bronze makes this replacement economically advantageous.
Ďalej je uvedený konkrétny příklad spósobu podía vynálezu.The following is a specific example of a method according to the invention.
Zlidíina hliníka s obsahom 12 % Si, 0,07 % Mn, 0,08 % Cr, 0,1 O/g Fe a 0,34 °/q Cu sa odliala do tvaru dosiek o hrúbke 18 mm. Z dósiěk sa odstranila náliatkdvá časť a takto ujárávěRe ^tíštu^óV&ii na valcovanie. Válcováním za tepla pri teplote 500 °C sa z došky válcovali pásy hrůbky 7 mm úbermi 25 %. Tieto pásy sa odmastili v parách trichloretylénu a po odmaštění sa previedlo na jednej straně zdrsnenie. Rovnakým spósobom sa odmastila a zdrsnila hliníková folia hrábky 0,5 mm. Pás z uvádzanej zliatiny a hliníková folia sa spolu združili válcováním pri teplote 5dO°C úbermi 30 °/0. Takto sa získal bimetalický pás hrůbky Ž mm. Birnětálifcký pás ,šd rovnakým spósobom ódrriáštil á ztífšríii há póHlihíkovanej straně. Rovnako sa odmastil a zdrsnil brúsením ócefový pás ČSN 11.321.21 o hrúbke 2,5 mm. Takto upravený ocefový pás a bimetalový pás sa zložili zdrsněnými stranami k sebe a združili válcováním za tepla pri 400 °C dvorná úbérmi 20 %. Z tohto vyrobeného pásu sa obvyklóu technológiou vyrábajú ložiskové púzdra.Aluminum alloy containing 12% Si, 0.07% Mn, 0.08% Cr, 0.1 O / g Fe and 0.34 ° / q Cu was cast into 18 mm thick plates. The inlet portion was removed from the plates and thus refined the rolling screen. Hot-rolled at 500 ° C was used to roll 7 mm thick strips from the thatch with 25% removal. These strips were degreased in trichlorethylene vapors and roughened on one side after degreasing. The aluminum foil of the rake 0.5 mm was degreased and roughened in the same way. Uvádzanej strip of alloy, and aluminum foil together with associated the rolling at 5dO ° C über 30 ° / 0th Thus, a bimetallic strip of depth Ž mm was obtained. The Birnetal waistband, in the same manner, has been truncated to the side of the side facing the side. It also degreased and roughened by grinding the ocephide strip ČSN 11.321.21 with a thickness of 2.5 mm. The steel strip and the bimetallic strip so treated were folded together with roughened sides and combined by hot rolling at 400 ° C with a backing of 20%. Bearing bushes are produced from this belt by conventional technology.
