Description

DK 153009BDK 153009B

Opfindelsen angår en kædeskive til rundledkæder med som kædeunderstøtning tjenende segmenter, som angivet i krav 1's indledning.The invention relates to a circular chain link disc with chain supporting segments as set forth in the preamble of claim 1.

Når en kædeskive af denne art optager en rundled kæde, 5 understøttes de "liggende" kædeled på segmenternes radialt yderste flader, der enten kan være glatte eller være tilpassede efter kædeleddenes form. De "stående" kædeled optages frit i mellemrummet mellem segmentparrene.When a chain disc of this kind occupies a circular chain, the "lying" chain links are supported on the radially outermost surfaces of the segments, which may either be smooth or be adapted to the shape of the chain links. The "standing" chain links are freely accommodated in the space between the segment pairs.

Segmenterne består sædvanligvis af metal. Under driften 10 opstår der støj og stødvise drejningsmomentændringer på grund af metalkædernes indløb på segmenternes metalflader. Til elimininering af stødvise ændringer af drejningsmomentet foreslås ifølge tysk offentliggørelsesskrift nr. 26 09 393 et mellemlag af elastisk deformerbare legemer.The segments usually consist of metal. During operation 10, noise and shock torque changes occur due to the inlet of the metal chains on the metal surfaces of the segments. For the elimination of shock changes in the torque, according to German Publication No. 26 09 393, an intermediate layer of elastically deformable bodies is proposed.

15 Ved drevne kædeskiver, hvis segmenter har en glat over flade, er friktionen mellem kædeskivens metal og kædens metal bestemmende for det drejningsmoment, der kan overføres. Til forøgelse af friktionen foreslås ifølge det tyske offentliggørelsesskrift nr. 12 11 036 at udfylde den til optagelse af kædeleddene tjenende not med en 20 ringformet foring af et elastisk materiale.15 For driven chainsaws whose segments have a smooth surface, the friction between the chainring metal and the chain metal determines the torque that can be transferred. In order to increase the friction, according to German publication specification No. 12 11 036, it is proposed to fill the groove serving to receive the chain links with an annular lining of an elastic material.

Ved en fra beskrivelsen til engelsk patent nr. 9 01 249 kendt kædeskive for kædeled opnås et forbedret friktionsindgreb og en reduktion af støjudviklingen ved, at der som understøtning for de liggende kædeled anvendes to ringskiver af et eftergiveligt materiale.By means of a chain disc for chain links known from the specification for English patent 9 01 249, an improved frictional engagement and a reduction of the noise development is obtained by the use of two annular discs of a resilient material as support for the lying chain links.

25 Ved denne kendte konstruktion er ringskiverne af eftergiveligt materiale og de til deres fastholdelse tjenende yderst anbragte ringskiver af metal ikke opdelt i segmenter, men strækker sig over hele omkredsen. Derved bliver hele tværsnittet af de massive, elastiske ringskiver deformeret ved kædens omløb, hvilket kan medføre, at spændin-30 gen af kæden varierer stærkt.In this known construction, the annular discs of resilient material and the extremely arranged metal annular discs are not divided into segments but extend over the entire circumference. Thereby, the entire cross-section of the solid, elastic ring washers is deformed at the chain orbit, which may cause the tension of the chain to vary greatly.

Endvidere kendes en i det væsentlige todelt, elastisk gummibelægning på drivhjulet ved bæltekøretøjer. Heller ikke ved denne konstruktion er den elastiske belægning opdelt i segmenter, og ved trækbelastning forekommer der således også her en deformering af 35 belægningen over hele omkredsen med deraf følgende varierende spænding af bæltekøretøjets bælter.Furthermore, a substantially two-piece, elastic rubber coating is known on the drive wheel by belt vehicles. Also, in this construction, the resilient coating is divided into segments, and with tensile loading, there is also here a deformation of the coating over the entire circumference with varying tension of the belt vehicle belts.

Formålet med opfindelsen er at formindske støjudviklingen ved en kædeskive af den indledningsvis nævnte art og at muliggøre overførsel af større drejningsmomenter til kæden.The object of the invention is to reduce the noise development of a chain disc of the kind mentioned above and to enable the transfer of larger torques to the chain.

Denne opgave løses ifølge opfindelsen ved en kædeskive, som er udformet med de i krav 1's kendetegnende del angivne ejendommeligheder.According to the invention, this task is solved by a chain disc which is formed with the characteristics specified in the characterizing part of claim 1.

Da hvert kædeled ved en kædeskive ifølge opfindelsen 5 optages af et tilstrækkeligt tykt dimensioneret lag af gummi opstår der ikke kraftig støj ved kædens bevægelse rundt om kædeskiven, således som det er tilfældet ved segmenter, der udelukkende består af metal. Muligheden for overførsel af større drejningsmomenter ved cylindriske understøtningsflader opnås ved en forøgelse af de på 10 kædeleddene virkende friktionskræfter, idet friktionen mellem gummi og metal er større end den ved de kendte kædeskiver sædvanlige friktion mellem metal og metal. Endvidere fås ved de cylindriske flader af gummi et formsluttende indgreb mellem kædeskiven og kædeleddene, fordi kædeleddene under udøvelse af en trykkraft ligger an 15 mod gummikappen og derved bevirker en elastisk deformering og tilpasning af gummiet efter kædeleddenes form.Since each chain link of a chain disc according to the invention is occupied by a sufficiently thick sized layer of rubber, no strong noise arises during the movement of the chain around the chain disc, as is the case with segments consisting entirely of metal. The possibility of transferring greater torque at cylindrical support surfaces is obtained by increasing the frictional forces acting on the 10 chain links, the friction between rubber and metal being greater than the usual friction between metal and metal. Furthermore, at the cylindrical surfaces of rubber, a form-fitting engagement between the chain washer and the chain links is obtained, because the chain joints, under the application of a compressive force, abut against the rubber sheath, thereby causing an elastic deformation and adaptation of the rubber to the shape of the chain links.

Hvert af segmenterne er udformet som en ringskive, der er omgivet af en kappe af gummi. Også de flader, med hvilke hvert segment ligger an mod skivelegemets krans, er for størstedelens 20 vedkommende af gummi og dermed lyddæmpende. Endvidere er segmenterne ved deres endeflader, med hvilke de ligger an mod andre segmenter, overtrukket med gummi. Den mekaniske stabilitet af segmenternes forbindelse med skivelegemet er opnået ved hjælp af den af metal bestående anlægsflade. Hvert segment ligger i området ved 25 boringerne an mod kransen med yderligere af metal bestående ringskiver. Endvidere er den af metal bestående segmentdel ved sin radialt inderste side understøttet på en cylindrisk flade på kransen.Each of the segments is designed as a ring washer surrounded by a rubber sheath. Also, the surfaces with which each segment abuts against the rim of the disc body are, for the most part, rubber and therefore sound attenuating. Furthermore, the segments at their end faces with which they abut other segments are coated with rubber. The mechanical stability of the segments' connection to the disc body is achieved by means of the metal surface. Each segment is in the region of the 25 bores against the wreath with additional metal ring washers. Furthermore, the metal segment segment at its radially inner side is supported on a cylindrical surface of the rim.

Til opnåelse af et direkte anlæg af hver bolts hoved eller en til bolten hørende møtrik er der ved boringen for bolten udformet en udsparing 30 i gummilaget.To obtain a direct abutment of the head of each bolt or a bolt associated with the bolt, a recess 30 in the rubber layer is formed at the bore of the bolt.

Selve tværsnitsformen af hvert segment er stabiliseret ved hjælp af den af metal bestående segmentdel, d.v.s. ringskiven, hvorved deformering af den elastiske kappe begrænses til den del, hvormed kappen er i understøttende indgreb med kædeled, d.v.s. det 35 radialt øverste område af segmenttværsnittet.The cross-sectional shape of each segment itself is stabilized by means of the metal segment segment, i.e. the ring disc, thereby limiting deformation of the resilient sheath to the portion with which the sheath is in supporting engagement with chain links, i.e. the 35 radially upper region of the segmental cross-section.

Understøtningsdelen af den elastiske kappe kan være udformet pi forskellig måde. Således kan understøtningsfladerne være cylindriske og være udformede med eller uden en radial flange ved hver side. De kan desuden også være udformede med fordybninger 3The support portion of the resilient sheath may be formed in various ways. Thus, the support surfaces may be cylindrical and be formed with or without a radial flange at each side. In addition, they may also be formed with recesses 3

eller udsparinger til optagelse af de kædeled, der under kædens bevægelse om kædeskiven ligger pi dette understøttende radialt yderste gummilag.or recesses for receiving the chain links which, during the movement of the chain about the chain disc, lie on this supporting radially outer rubber layer.

Ved hjælp af på ringskivens indadvendende side påstøbte 5 eller påsvejste ribber kan der opnås en yderligere forbedret understøtning af segmenterne på den radialt yderste cylindriske flade af skivefegemets krans.By means of 5 or welded ribs cast on the inner side of the annular disc, further improved support of the segments can be obtained on the radially outermost cylindrical surface of the wafer rim.

I det følgende forklares en udførelsesform for kædeskiven ifølge opfindelsen nærmere under henvisning til tegningen. På tegnin-10 gen viser: fig. 1 et billede af en fjerdedel af kædeskiven ifølge opfindelsen set i aksial retning, fig. 2 et snit som vist ved il i fi. 1 og fig. 3 et snit gennem et segment, som vist ved III i 15 fig. 1 i større målestok.In the following, an embodiment of the chain disc according to the invention is explained in more detail with reference to the drawing. In the drawing: FIG. 1 is an axial view of a quarter of the chain disc according to the invention; FIG. 2 is a section as shown by il in fi. 1 and FIG. 3 is a section through a segment, as shown by III in FIG. 1 on a larger scale.

På kransen af et helt af stål eller støbestål bestående kæde-skivelegeme 10 er der ved begge sider langs hele omkredsen fastgjort segmenter 20, der danner to cylindriske understøtningsflader for de liggende kædeled. Hvert segment strækker sig over en vinkelbue på 20 45°, således at kædeskiven har i alt 16 segmenter. Denne vinkelbue og antallet af segmenter gælder for den viste udførelsesform. Ved større eller mindre kædeskiver ændres vinkelbuen og antallet af segmenter. Segmenterne er parvis ved siden af hinanden fastgjorte til kransen af kædes kivel egernet 10 ved hjælp af to gevindbolte 14. Hvert 25 segment ligger an mod en cylindrisk flade 11 og en plan sideflade 12 på kædeskivens krans. Endvidere understøttes hvert segment mod en midterste cylindrisk flade 13 på kransen ved hjælp af to på segmentet udformede ribber 24. Segmenterne danner, set i tværsnit, to cylindriske understøtningsflader 26, på hvilke liggende kædeled 27 under-30 støttes under deres bevægelse rundt om kædeskiven. De stående kædeled optages delvis i mellemrummet mellem segmenterne. Segmenterne kan være udformede med en radial flange 26a til føring af de liggende kædeled.On the rim of a whole steel or cast steel chain disc body 10, segments 20 are fixed on both sides along the entire circumference, forming two cylindrical support surfaces for the lying chain links. Each segment extends over an angular arc of 20 to 45 °, so that the sprocket has a total of 16 segments. This angular arc and the number of segments apply to the embodiment shown. For larger or smaller chain washers, the angular arc and number of segments change. The segments are attached in pairs side by side to the wreath of chain sprocket squirrel 10 by means of two threaded bolts 14. Each 25 segment abuts against a cylindrical surface 11 and a flat side surface 12 on the wreath of the sprocket. Furthermore, each segment is supported against a middle cylindrical surface 13 of the wreath by two ribs 24 formed on the segment. The standing chain links are partially accommodated in the space between the segments. The segments may be formed with a radial flange 26a for guiding the lying chain links.

Opbygningen af hvert segment ses i fig. 3. Segmentet 35 består af en metal kerne (ringskive) 21 af stål, støbestål, støbejern eller et andet metal med passende mekanisk styrke. Pi den ene side af kernen 21 er påsvejst to ribber 24. Endvidere har kernen to boringer 22 til optagelse af gevindbolte til fastgørelsen. Disse boringer forlænges ved hjælp af påsvejste ringskiver 23 ved den side, 4The structure of each segment is shown in FIG. 3. The segment 35 consists of a metal core (annular disc) 21 of steel, cast steel, cast iron or other metal of appropriate mechanical strength. On one side of the core 21, two ribs are welded 24. Furthermore, the core has two bores 22 for receiving threaded bolts for fastening. These bores are extended by means of welded washers 23 at the side 4

hvor også ribberne er pisvejst.where the ribs are also welded.

Kernen er ved begge sider og foroven samt ved endesiderne omgivet af en kappe af gummi. Denne kappe danner en understøtningsdel 25 med tilnærmelsesvis samme bredde som segmentets bredde og 5 med en cylindrisk flade 26 som understøtningsflade for kædeleddene.The core is surrounded on both sides and at the top as well as at the end sides by a rubber jacket. This sheath forms a support portion 25 of approximately the same width as the width of the segment and 5 with a cylindrical surface 26 as the support surface for the chain links.

Ved kappens udadvendende side er udformet en udsparing 28, der tjener til optagelse af gevindboltens hoved eller møtrik.A recess 28 is provided at the outwardly facing side of the sheath which serves to receive the threaded head or nut.

Når segmenterne er anbragt fast på kædeskiven, ligger en bundflade 21b samt flader af formstof kappen ved begge sider an mod 10 kransens cylindriske flade 11. Endvidere ligger ringskiven 23 og den tilstødende kappedel an mod den plane sideflade 12 af kransen. Ribberne 24 er understøttet på kransens cylindriske flade 13.When the segments are affixed to the warp disc, a bottom surface 21b and surfaces of the plastic casing on both sides abut the cylindrical surface of the wreath 11. Furthermore, the annular disc 23 and the adjacent cutting portion abut the flat side surface 12 of the wreath. The ribs 24 are supported on the cylindrical surface 13 of the garland.
