Description
7909659-0 sulfid. 7909659-0 sulfide.
Enligt uppfinningen är nämnda spår anordnade i en väl definierad konfiguration och bildas av bottenhål, vars axlar befinner sig på minst en omkrets. Lämpligen är hålens axlar anordnade på flera koncentriska omkretsar och axlarna hos hålen, som befinner sig på två närliggande omkretsar, befinner sig ej utefter samma radie hos omkretsarna.According to the invention, said grooves are arranged in a well-defined configuration and are formed by bottom holes, the axes of which are at least one circumference. Preferably, the axes of the holes are arranged on several concentric perimeters and the axes of the holes, which are located on two adjacent perimeters, are not located along the same radius of the perimeters.
Uppfinningen belyses närmare nedan med avseende på de fundamenta- la stegen vid uppbyggnaden av parelementen i anslutning till bifo- gade ritningsfigurer, av vilka fig. 1 är en sidovy av en platta utgörande ett av elementen i ett elementpar enligt uppfinningen, fig. 2 visar en sidovy av ett annat element enligt uppfinningen, i vilket återfinns smörjmedelskanaler anordnade i en konfiguration annan än den som är visad i fig. 1, fig. 3 visar en sidovy av en annan platta enligt uppfinningen och fig. 4 och 5 visar tvärsektioner i ett plan vinkelrätt mot glid- ytan hos en av plattorna visade i föregående figurer under tvâ på varandra följande steg vid processen.The invention is further elucidated below with respect to the fundamental steps in the construction of the pair elements in connection with the accompanying drawing figures, of which Fig. 1 is a side view of a plate constituting one of the elements in a pair of elements according to the invention, Fig. 2 shows a side view of another element according to the invention, in which there are lubricant channels arranged in a configuration other than that shown in Fig. 1, Fig. 3 shows a side view of another plate according to the invention and Figs. 4 and 5 show cross sections in a plane perpendicular to the sliding surface of one of the plates shown in the preceding figures during two consecutive steps in the process.
Uppfinningen beskrives nu under hänvisning till de tre olika plat- torna visade i fig. 1-3 men det är uppenbart att uppfinningen kan tillämpas på elementpar uppvisande annan form.The invention is now described with reference to the three different plates shown in Figs. 1-3, but it is obvious that the invention can be applied to element pairs having a different shape.
Ett elementpar format som en platta 1 (fig. 1) uppvisar en glidyta 2, som i det visade fallet är plan och avsedd att glida mot en mot- svarande plan yta hos det andra elementet (ej visat) i elementpa- ret och som är i huvudsak av samma slag som det i figuren visade elementet. Plattan är försedd med en kanal för ett smörjmedel av i och för sig känd typ, vilken kanal är avsedd att transportera ol- ja mellan de i ingrepp med varandra varande ytorna, vilken olja kom- mer från ett inmatningshål 4. Plattan är i likhet med övriga nedan beskrivna plattor av brons (normal eller av specialtyp) och till- verkad genom konventionell formningstyp.An element pair shaped as a plate 1 (Fig. 1) has a sliding surface 2, which in the case shown is flat and intended to slide against a corresponding flat surface of the second element (not shown) in the element pair and which is substantially of the same kind as the element shown in the figure. The plate is provided with a channel for a lubricant of a per se known type, which channel is intended to transport oil between the engaging surfaces, which oil comes from a feed hole 4. The plate is similar to other bronze (normal or special type) tiles described below and made by conventional molding type.
Plattorna visade i fig. 2 och 3, som uppvisar i huvudsak samma form som den ovan_beskrivna, är försedda med smörjningskanaler uppvi- sande sektioner med en konfiguration som skiljer sig från den ovan beskrivna. I fallet med plattan visad i fig. 2 står en central sek- 7909659-0 tion 5 i förbindelse med sektionen 6, som löper ut radiellt från den centrala sektionens ändar och oljan tillföres genom hålen 7.The plates shown in Figs. 2 and 3, which have substantially the same shape as the one described above, are provided with lubrication channels having sections having a configuration different from that described above. In the case of the plate shown in Fig. 2, a central section 5 communicates with the section 6, which extends radially from the ends of the central section and the oil is supplied through the holes 7.
Hos utföringsformen enligt fig. 3 återfinns flera parallella ka- nalsektioner 8, som står i förbindelse med varandra och med ett inmatningshål 9 via förbindningssektioner 10.In the embodiment according to Fig. 3 there are several parallel channel sections 8, which are connected to each other and to an input hole 9 via connecting sections 10.
Enligt uppfinningen är på ytan 2 hos varje platta formade ett fler- tal fördjupningar, som var och en exempelvis utgöres av ett bot- tenhål av den typ som är visad i fig. 4. Varje sådant hål är fyllt med ett inlägg 13 av ett lämpligt material på sådant sätt, att in- läggets ovansida 14 (fig. 5) i huvudsak sammanfaller med ytan 2 hos plattan.According to the invention, a plurality of depressions are formed on the surface 2 of each plate, each of which is constituted, for example, by a bottom hole of the type shown in Fig. 4. Each such hole is filled with an insert 13 of a suitable material in such a way that the upper side 14 (fig. 5) of the insert substantially coincides with the surface 2 of the plate.
Materialet som bildar inlägget 13 är ett material med antifriktions- och kärvningsmotstândsegenskaper, som är högre än de hos brons, som bildar materialet i plattan. För detta ändamål kan gängse vi- ta antifriktionsmetaller användas, som innehåller ganska höga mäng- der tenn (normalt ca 80%) liksom substitutionslegeringar för vit- metaller, nämligen av den typ som normalt används i lager och som är baserade på bly med tillsats av kadmium, arsenik, fosfor, vana- din eller nickel eller andra legeringar som används i lager, såsom sådana på basis av kadmium och innehållande även nickel, koppar el- ler silver. Lämpliga är även zinklegeringar eller lätta legeringar (legeringar av aluminium härdade exempelvis med bly). Den fundamen- tala egenskapen hos materialet i inläggen 13 är antifriktions- och kärvningsmotståndsegenskaper högre än motsvarande hos brons. Även om dessa egenskaper ej kan definieras strikt och numeriskt med an- vändning av exakta mätenhetcr, avser de att beteckna det komplex av egenskaper, som bidrar till att nedbringa den totala friktions- koefficienten i rörelsen mellan de två parelementen och undvika alstring av kärvningsfenomen, i synnerhet i samband med dålig smörjning under ganska höga inbördes tryck och temperaturer.The material forming the insert 13 is a material having anti-friction and tearing resistance properties higher than those of the bronze forming the material in the plate. For this purpose, ordinary white antifriction metals can be used, which contain quite high amounts of tin (normally about 80%) as well as substitution alloys for white metals, namely of the type normally used in bearings and which are based on lead with the addition of cadmium, arsenic, phosphorus, vanadium or nickel or other alloys used in storage, such as those based on cadmium and also containing nickel, copper or silver. Zinc alloys or light alloys are also suitable (alloys of aluminum hardened, for example with lead). The fundamental property of the material in the inserts 13 is antifriction and notch resistance properties higher than those of bronze. Although these properties cannot be defined strictly and numerically using precise units of measurement, they are intended to denote the complex of properties which contribute to reducing the total coefficient of friction in the movement between the two pair elements and avoiding the generation of jamming phenomena. especially in connection with poor lubrication under rather high relative pressures and temperatures.
Enligt en alternativ lösning kan materialet i inläggen 13 formas av en blandning innehållande ett smörjmedel. Denna blandning kan innehålla ett basmaterial av ganska plastisk natur, som är lämpligt att införa i urtagen 12 och som hårdnar med tiden utan att för den skull uppnå en fullständig härdning. Lämpliga basmaterial kan be- redas av gummiblandningar, elaster, plastmaterial och liknande.According to an alternative solution, the material in the inserts 13 can be formed from a mixture containing a lubricant. This mixture may contain a base material of a rather plastic nature, which is suitable for insertion into the recesses 12 and which hardens over time without achieving a complete cure for that purpose. Suitable base materials can be prepared from rubber compounds, elastomers, plastic materials and the like.
Smörjmedlet kan vara vilket som helst smörjmedel, t.ex. ett smörj- 7909659-0 medelspulver, såsom molybdendisulfid.The lubricant can be any lubricant, e.g. a lubricant powder, such as molybdenum disulfide.
Urtagen 12 kan lämpligen vara placerade i sådana områden hos ett element, där smörjningen är mindre effektiv och de specifika tryc- ken är högre, dvs inom områden där kärvningsfenomen kan tänkas uppträda.The recesses 12 may suitably be located in such areas of an element, where the lubrication is less effective and the specific pressures are higher, ie in areas where jamming phenomena may occur.
Vad beträffar utföringsformerna visade på ritningsfigurerna åter- finns nämnda områden i sidoregionerna av plattan 1 nära ändarna av smörjkanalerna.With regard to the embodiments shown in the drawing figures, said areas are found in the side regions of the plate 1 near the ends of the lubrication channels.
Hålens 12 axlar är lämpligen anordnade på en eller flera koncent- riska omkretsar såsom är visat i fig. 1 och 2. För att på likfor- migast möjliga sätt fördela antalet inlägg 13 inom det område, där det är önskvärt att undvika uppkomst av kärvningsfenomen, är hålens 12 axlar hos två närliggande omkretsar ej belägna på samma radie, såsom klart kan framgå av fig. 1 och 2. Det är uppenbart att hålen 12 kan uppvisa varje annan konfiguration, som möjliggör i huvudsak likformig fördelning av inläggen 13 inom det önskade omrâdet och exempelvis i fallet med plattan visad i fig. 3 är hålen 12 placera- de utmed en i huvudsak rät linje mellan smörjmedelskanalerna 8 och utanför dessa kanaler.The axes of the holes 12 are suitably arranged on one or more concentric perimeters as shown in Figs. 1 and 2. In order to distribute the number of inserts 13 in the most uniform way possible within the area where it is desirable to avoid the occurrence of jamming phenomena, the axes of the holes 12 of two adjacent perimeters are not located on the same radius, as can be clearly seen from Figs. 1 and 2. It is obvious that the holes 12 can have any other configuration, which enables substantially uniform distribution of the inserts 13 within the desired area. and, for example, in the case of the plate shown in Fig. 3, the holes 12 are located along a substantially straight line between the lubricant channels 8 and outside these channels.
På en platta av det slag som är visad i fig. 1, 2 och 3 erhållen genom smältning, är formade ett flertal hål 12, som är anordnade enligt det mönster som är visat i figurerna. I varje hål hälls ma- terialen för inläggen 13 (i fallet med ett metalliskt material) el- ler fylls på lämpligt sätt hålen med en blandning innehållande smörjmedel. Slutligen slipas ytan hos materialet i inläggen 13 ned i plan med ytan 2.On a plate of the type shown in Figs. 1, 2 and 3 obtained by melting, a plurality of holes 12 are formed, which are arranged according to the pattern shown in the figures. In each hole the material for the inserts 13 is poured (in the case of a metallic material) or the holes are suitably filled with a mixture containing lubricant. Finally, the surface of the material in the inserts 13 is ground down flush with the surface 2.
Det har visat sig att vid användning av ett elementpar enligt upp- finningen förbättras beteendet i jämförelse med hos ett konventio- nellt elementpar med samma dimensioner under samma smörjningsbe- tingelser och utsatta för samma belastning. Ett lägre värde på den totala friktionskoefficienten och en bättre beständighet mot upp- komst av kärvningsfenomen uppnås. Sannolikt beror detta på den gynn- samma inverkan som utövas av materialet i inläggen 13, vilket ma- terial är av en annan natur än i själva plattan och varigenom en gynnsam samverkan uppnås. En sådan effekt uppnås även med inlägg 7909659-0 13 uppvisande en ganska reducerad yta, som uppenbarligen endast utgör en liten bråkdel av plattans totala yta.It has been found that when using an element pair according to the invention, the behavior is improved in comparison with that of a conventional element pair with the same dimensions under the same lubrication conditions and exposed to the same load. A lower value of the total coefficient of friction and a better resistance to the occurrence of jamming phenomena are achieved. This is probably due to the favorable effect exerted by the material in the inserts 13, which material is of a different nature than in the plate itself and whereby a favorable cooperation is achieved. Such an effect is also achieved with inserts having a rather reduced surface area, which apparently constitutes only a small fraction of the total surface area of the plate.
Det är uppenbart att modifieringar och variationer kan utföras i elementparen utan att man går utanför uppfinningens ram. >.._....,.--.-f--~--It is obvious that modifications and variations can be made in the element pairs without departing from the scope of the invention. > .._....,. - .- f-- ~ -
