Flank Contact Silent Chain – Product Overview<\/h2>\n
\n
\n

Igavene j\u00f5ud k\u00fclgkontaktiga vaiksed ketid<\/a> – also known as inverted tooth chains – are a fundamentally different chain design from conventional roller chains. Where a roller chain engages the sprocket through rollers sitting in the tooth spaces and being lifted in and out of engagement as the chain wraps around the sprocket, a silent chain engages through the flanks of toothed link plates that mesh with the sprocket teeth in a manner resembling gear tooth engagement. This flank contact principle is what gives the silent chain its defining characteristic: smooth, near-silent operation at high speed without the chordal action noise that makes roller chains increasingly loud as chain speed rises above about 6 m\/s.<\/p>\n

The EP-SC3, EP-SC4, and EP-SC5 series follow the GB (Chinese national standard) designation for flank contact silent chains. EP-SC3 has a pitch of 9.525 mm – the smallest in the range – and is used in compact high-speed drives where the sprocket diameter must be small. EP-SC4 at 12.700 mm pitch is the most widely used silent chain in industrial and automotive applications, balancing load capacity, speed capability, and sprocket size. EP-SC5 at 15.875 mm pitch is the heaviest-duty series, used where the power to be transmitted is too high for a single EP-SC4 chain of practical width, or where the slower speed of the drive allows the larger pitch.<\/p>\n

Each pitch series is available in a wide range of chain widths, expressed in the specification table as the minimum inner width b (mm). The chain width determines the number of link plates across the chain width (column n in the table) and directly governs the tensile strength and power capacity of the chain. A wider chain – more plates – carries proportionally more load. The chain width is specified in 3 mm increments for EP-SC3, and varies by series for EP-SC4 and EP-SC5.<\/p>\n

Saadaval on kaks juhiku konfiguratsiooni. Keskmine juhend (Keskmine juhend)<\/strong> kasutab keti laiuse keskel juhtplaati, mis kulgeb ketiratta keskele freesitud soones. See on standardkonfiguratsioon enamiku t\u00f6\u00f6stuslike k\u00e4igukastide ja autode hammas\u00fclekande rakenduste jaoks. K\u00fclgjuhend (k\u00fclgjuhend)<\/strong> uses guide plates at both outer edges of the chain, running on the outer faces of the sprocket. Side guide is used where the sprocket cannot have a centre groove – for example, in applications sharing a sprocket with another drive element, or where the sprocket is too narrow to machine a centre groove.<\/p>\n<\/div>\n

Silent Chain – Key Technical Features<\/h2>\n
\n
\n

Flank Contact Engagement – No Chordal Action<\/h3>\n

P\u00f6\u00f6ratud hambaplaadi k\u00fcljed haakuvad ketiratta hambak\u00fclgedega libisevas kontaktis, mis v\u00e4listab k\u00f5igis rullkettide ajamites esineva ts\u00fcklilise kiiruse k\u00f5ikumise (kordilise toime). Rullketis muutub keti kiirus sinusoidaalselt, kui iga rull siseneb ketiratta hambavahesse ja lahkub sellest; see k\u00f5ikumine suureneb koos keti kiirusega ja on rullketi m\u00fcra ja vibratsiooni peamine allikas suurel kiirusel. H\u00e4\u00e4letud ketid on sellest efektist vabad, pakkudes t\u00f5eliselt sujuvat kiiruse suhet ja peaaegu vaikset t\u00f6\u00f6 isegi kiirustel \u00fcle 20 m\/s.<\/p>\n<\/div>\n

\n

Laiusel p\u00f5hinev koormuse skaleerimine<\/h3>\n

Silent chain load capacity scales linearly with chain width because load is shared across all plates in the width. For a given pitch, selecting a wider chain increases the tensile strength and power capacity without any change to the pitch or sprocket. This makes silent chains particularly flexible for power upgrading – moving from EP-SC4-28.5 (35.2 kN) to EP-SC4-61.5 (78.2 kN) requires only a wider chain and sprocket at the same 12.7 mm pitch.<\/p>\n<\/div>\n

\n

Keskmise ja k\u00fclgmise juhiku konfiguratsioonid<\/h3>\n

Keskjuhikuga (Middle Guide) ketid kasutavad ketiratta pinna soones kulgevat keskset juhtplaati, hoides keti tsentraalselt liikumas ilma k\u00fclgmise triivita. See on enamiku suletud k\u00e4igukastide ja autode hammas\u00fclekannete standardkonfiguratsioon. K\u00fclgjuhikuga (Side Guide) ketid kasutavad juhtplaate m\u00f5lemas v\u00e4lisservas, mis sobib kohtadesse, kus kesksoont ei ole v\u00f5imalik luua. Kitsamate laiuste EP-SC3 ja EP-SC4 puhul kasutatakse k\u00fclgjuhikut; laiemate kettide puhul, millel on rohkem plaate laiuses, kasutatakse keskmist juhikut.<\/p>\n<\/div>\n

\n

Kiire v\u00f5imekus<\/h3>\n

9,525 mm sammuga EP-SC3 vaiksed ketid suudavad \u00f5ige m\u00e4\u00e4rimise korral usaldusv\u00e4\u00e4rselt t\u00f6\u00f6tada ketikiirustel \u00fcle 20 m\/s, \u00fcletades oluliselt sama sammuga rullkettide praktilist piiri. 12,700 mm sammuga EP-SC4 on pidevaks t\u00f6\u00f6ks ette n\u00e4htud kuni umbes 15 m\/s ja 15,875 mm sammuga EP-SC5 sobib kiirustele kuni 10 m\/s. Need omadused muudavad vaiksed ketid eelistatud valikuks kiirete nukkv\u00f5lli ajamite, generaatori ajamite ja igasuguste rakenduste jaoks, kus m\u00fcra on peamine piirang.<\/p>\n<\/div>\n

\n

\u00d5livanni m\u00e4\u00e4rimine<\/h3>\n

Vaiksed ketid vajavad pidevat \u00f5lim\u00e4\u00e4rimist, tavaliselt \u00f5livannist, millesse kett osaliselt sukeldub, liikudes \u00fcmber alumise ketiratta, v\u00f5i \u00f5lipihustist, mis on suunatud keti ja ketiratta kokkupuutealale. Erinevalt rullkettidest, mis taluvad vahelduvat \u00f5li pealekandmist madalatel kiirustel, vajavad vaiksed ketid k\u00fclgkontakti tsoonis alati pidevat \u00f5lifilmi. \u00d5li t\u00e4idab ka soojuse eemaldamise funktsiooni, juhtides \u00e4ra h\u00f5\u00f5rdesoojuse, mis tekib k\u00fclgkontakti liideses suurel kiirusel t\u00f6\u00f6tamise ajal.<\/p>\n<\/div>\n

\n

T\u00e4ppishambaratta hammaste kuju<\/h3>\n

Vaiksetel ketiratastel on 30-kraadise nurga all sirgete k\u00fclgedega hambaprofiil (nagu on n\u00e4idatud spetsifikatsioonitabeli \u00fclaosas oleval m\u00f5\u00f5tjoonisel), mitte rullketi ketirataste evolventne hammaskuju. Keti korrektseks haardumiseks tuleb hambaprofiil t\u00e4pselt t\u00f6\u00f6delda etten\u00e4htud 30-kraadise nurga ja h1 m\u00f5\u00f5tmega (augu keskpunktist hambatipuni). Kulunud, valesti t\u00f6\u00f6deldud v\u00f5i vale hambaprofiiliga ketirattad p\u00f5hjustavad keti kiiret kulumist ja m\u00fcra teket. EP saab tarnida sobitatud ketirattaid kontrollitud 30-kraadise hambaprofiiliga k\u00f5ikidele SC3, SC4 ja SC5 keti suurustele.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Rakendused<\/h2>\n
\n
\n

Autode nukkv\u00f5lli ja hammas\u00fclekanded<\/h3>\n

EP-SC3 ja EP-SC4 kette kasutatakse laialdaselt automootorite nukkv\u00f5lli ajastus\u00fclekannetes, \u00f5lipumpade ajamites ja tasakaalustusv\u00f5lli ajamites. Vaikne t\u00f6\u00f6 v\u00e4listab ajastusahela ragisemise, mis vaevab rullkettide ajastus\u00fclekandeid k\u00fclmk\u00e4ivituse ajal, kus \u00f5li viskoossus aeglustab m\u00e4\u00e4rdeaine j\u00f5udmist ketini. Vaikse keti haarde t\u00e4pne kiirussuhe tagab ka t\u00e4psema klapiajastuse kui rullkettide alternatiivid, aidates kaasa madalamatele heitkogustele ja paremale k\u00fctusekulule mootori arendustasandil.<\/p>\n<\/div>\n

\n

T\u00f6\u00f6stuslikud k\u00e4igukastid ja t\u00f6\u00f6pingid<\/h3>\n

EP-SC4 ja EP-SC5 ketid on ette n\u00e4htud suletud t\u00f6\u00f6stuslike k\u00e4igukasti ajamite, t\u00f6\u00f6pinkide spindli ajamite ja t\u00e4ppist\u00f6\u00f6tlemisseadmete jaoks, mille puhul m\u00fcra on kvaliteedi ja regulatiivsete kriteeriumide t\u00e4itmiseks. Tekstiilimasinad, tr\u00fckimasinad ja pakendamisseadmed kasutavad k\u00f5ik primaarajamites vaikseid kette, mille puhul rullketi m\u00fcra oleks nii operaatoritele vastuv\u00f5etamatu kui ka potentsiaalselt varjaks mehaaniliste rikete m\u00fcra, mida hooldusmeeskonnad peavad tuvastama. EP-SC4 laiustega 28,5 mm kuni 61,5 mm katab enamiku k\u00e4igukastide ja t\u00f6\u00f6pinkide ajamite n\u00f5uetest.<\/p>\n<\/div>\n

\n

Generaatori ja kompressori ajamid<\/h3>\n

EP-SC4 ja EP-SC5 vaikketiga generaatori- ja kompressoriajamid saavad kasu sujuvast kiirussuhtest, mis v\u00e4hendab k\u00e4itatavat seadet ergastavat v\u00e4\u00e4ndvibratsiooni. Generaatorirakendustes moduleerib rullketiga ajami kiirussuhte muutus veidi v\u00e4ljundpinget ja -sagedust; vaikne kett k\u00f5rvaldab selle modulatsiooni. Kolbkompressori ajamites v\u00e4hendab vaikne kett ajamis v\u00e4\u00e4ndvibratsiooni amplituudi, pikendades laagrite ja v\u00f5llitihendite eluiga v\u00f5rreldes sama v\u00f5imsustasemega rullkettidega.<\/p>\n<\/div>\n<\/div>\n

\n
\nMiks on sama kiiruse juures vaikne kett vaiksem kui rullkett?<\/summary>\n
A roller chain engages the sprocket by with each roller falling into a tooth space as the chain wraps around the sprocket. As the roller settles into the tooth space, there is an impact – the roller hitting the tooth – which generates noise proportional to the impact velocity and chain speed. At high speed, this impact noise becomes dominant. A silent chain engages differently: the inverted tooth plate flanks slide along the sprocket tooth flanks in a meshing action, with the engagement velocity much lower than the equivalent roller impact velocity. The 30-degree tooth angle also distributes the engagement contact over a short sliding distance rather than a single impact point, further reducing the noise impulse per tooth engagement.<\/div>\n<\/details>\n
\nMis vahe on keskmisel juhikul (Middle Guide) ja k\u00fclgjuhikul (Side Guide)?<\/summary>\n
Middle guide chains (Middle Guide) have one or more guide plates positioned at the centre of the chain width. These guide plates have a flat face that runs in a groove machined into the centre of the sprocket face, keeping the chain aligned laterally as it travels around the sprocket. The groove on the sprocket face is the key identifier – look for a central groove in the sprocket. Side guide chains (Side Guide) have guide plates at both outer edges of the chain, and these guide plates run on raised rim faces on the outer edges of the sprocket rather than in a groove. The specification table uses Side (Outside) to indicate side guide and Middle (Inside) to indicate middle guide. When ordering a replacement chain, verify which guide type the existing sprockets are machined for before specifying the chain.<\/div>\n<\/details>\n
\nKuidas ma saan oma v\u00f5imsusvajadusele vastava keti laiuse m\u00e4\u00e4rata?<\/summary>\n
Valige esmalt samm (SC3, SC4 v\u00f5i SC5), l\u00e4htudes saadaolevast ketiratta suurusest ja keti kiirusest. Seej\u00e4rel arvutage keti pinge \u00fclekantava v\u00f5imsuse p\u00f5hjal: pinge (kN) = v\u00f5imsus (kW) jagatud keti kiirusega (m\/s). Rakendage ajamit\u00fc\u00fcbile vastavat hooldustegurit (1,0 sujuva, 1,3 m\u00f5\u00f5duka amortisatsiooni ja 1,5 tugeva amortisatsiooni korral), et saada kavandatud pinge. Jagage kavandatud pinge 5-ga (minimaalne ohutustegur vaiksete kettide puhul), et saada n\u00f5utav minimaalne t\u00f5mbetugevus. Leidke spetsifikatsioonitabelist valitud sammu seeria esimene rida, kus Q min (kN) \u00fcletab selle n\u00f5utava v\u00e4\u00e4rtuse ja see on teie rakenduse minimaalne keti laius. Valige j\u00e4rgmine suurus, kui arvutatud laius on Q min veeru piiril.<\/div>\n<\/details>\n
\nMillist m\u00e4\u00e4rimist on vaja vaiksete kettide jaoks?<\/summary>\n
Silent chains require continuous oil lubrication at all times during operation. The preferred method is oil bath lubrication, where the chain partially submerges in an oil sump as it passes around the lower sprocket – the oil is carried into the flank contact zone by the chain and sprocket rotation. The oil level should be maintained at the centre of the lower sprocket shaft. For high-speed applications (above 10 m\/s), oil spray directed at the chain-sprocket engagement point is preferred, as the chain speed throws bath oil away from the contact zone before it can enter. Use ISO VG 100 to VG 220 mineral oil depending on operating temperature. Change the oil at the manufacturer-recommended intervals – contaminated oil with metallic particles from chain wear will accelerate tooth and plate wear significantly.<\/div>\n<\/details>\n
\nMillised on m\u00e4rgid, et summuti vajab vahetamist?<\/summary>\n
Vaiksete kettide peamine kulumisn\u00e4itaja on pikenemine, mida m\u00f5\u00f5detakse sammu protsentuaalse suurenemisena 10-l\u00fclilise sektsiooni ulatuses v\u00f5rreldes nimiv\u00e4\u00e4rtusega. Vahetage kett v\u00e4lja, kui pikenemine saavutab 1,5% t\u00e4ppisajamite (autode ajastus, t\u00f6\u00f6pingid) v\u00f5i 2,0% \u00fcldiste t\u00f6\u00f6stuslike ajamite puhul. Visuaalsed m\u00e4rgid, mis viitavad vahetamise vajadusele, on: n\u00e4htav kulumine plaadi k\u00fclgede kontaktpindadel (poleeritud v\u00f5i soonelised alad l\u00fcliplaatide 30-kraadise pinna peal); l\u00f5tk v\u00f5i l\u00f5tk tihvtide \u00fchendustel, mis on suurem kui uue keti puhul t\u00fc\u00fcpiline; kett on ketiratta hammastel n\u00e4htavalt k\u00f5rgemale kulunud kui uue ketiga (mis n\u00e4itab, et hambaots ei puutu enam kokku plaadiakna p\u00f5hjaga); v\u00f5i keti m\u00fcra on taastunud vaatamata \u00f5igele m\u00e4\u00e4rimisele, mis n\u00e4itab, et k\u00fclje kontaktgeomeetria on algsest profiilist eemale kulunud.<\/div>\n<\/details>\n
\nKas vaikseid kette saab l\u00f5igata parajaks ja \u00fchendada \u00fchendusl\u00fcliga?<\/summary>\n
Jah. Vaikse ookeani hammasrattad l\u00f5igatakse vajaliku sammude arvuni ja \u00fchendatakse \u00fchendustihvtiga. Spetsifikatsioonitabelis olev Lc max m\u00f5\u00f5t on \u00fchendusl\u00fcli positsiooni tihvti pikkus, mis on veidi pikem kui L max jooksva tihvti pikkus, et mahutada keti otstes splint v\u00f5i vedruklamber. Vaikse ookeani hammasratta l\u00f5ikamisel tuleb l\u00f5ige teha tihvti positsioonilt, mitte l\u00e4bi plaadi. Ahela sammude arv tuleb m\u00e4\u00e4rata ketirataste vahelise keskpunkti kauguse ja ketiratta hammaste arvu j\u00e4rgi, kasutades standardset keti pikkuse valemit. Autode hammasrataskettide puhul on pikkus fikseeritud mootori konstruktsiooniga ja need tuleks tellida mootori hooldusjuhendis t\u00e4psustatud t\u00e4pse l\u00fclide arvu j\u00e4rgi, mitte arvutada.<\/div>\n<\/details>\n<\/div>\n

“We replaced roller chains on our high-speed printing press intermediate drives with EP-SC4-34.5 silent chains. The noise level in the press room fell by approximately 6 dB immediately after installation. Operators noticed the difference within the first shift. The EP chains have been running for 14 months at 12 m\/s chain speed with no significant elongation and no lubrication issues.”<\/p>\n

“We specified EP-SC3 chains for our compact generator sets. The roller chain drive on the original design was generating vibration that showed up in the output voltage waveform. Switching to EP-SC3-22.5 silent chains eliminated the velocity ratio variation and the voltage ripple dropped below the instrument detection threshold. A straightforward solution to what had been a difficult problem.”<\/p>\n

“EP-SC5-54.0 chains for our industrial gearbox output drives at 8 m\/s. We ordered six chains with 10-pitch measurement confirmation on delivery. All six chains measured within 0.06 mm of nominal over the 10-pitch test length. Installation was straightforward and the chains have been running for 22 months without any adjustment. Very satisfied with the dimensional quality.”<\/p>\n

“We use EP-SC4 chains in our textile machinery main drives. The key requirement is consistent pitch – any variation shows up as fabric defect in the weave. EP chains have never caused a pitch-related fabric fault in three years of production use. The middle guide tracking is also very stable; we have not needed to adjust sprocket alignment after the initial installation on any of the 24 looms fitted.”<\/p>\n
