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

Vje\u010dna Mo\u0107 tihi lanci s bo\u010dnim kontaktom<\/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

Dostupne su dvije konfiguracije vodi\u010da.

Ovo je standardna konfiguracija za ve\u0107inu industrijskih mjenja\u010da i automobilskih pogona za zup\u010dasti mehanizam. Bo\u010dni vodi\u010d (Bo\u010dni vodi\u010d)<\/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

Invertovane bo\u010dne strane zuba plo\u010de zahvataju bo\u010dne strane zuba lan\u010danika u kliznom kontaktnom djelovanju koje eliminira cikli\u010dku promjenu brzine (tetivno djelovanje) prisutnu u svim pogonima s valjkastim lancima. Kod valjkastog lanca, brzina lanca se mijenja sinusoidno kako svaki valjak ulazi i izlazi iz prostora zuba lan\u010danika; ova varijacija se pove\u0107ava s brzinom lanca i primarni je izvor buke i vibracija valjkastog lanca pri velikim brzinama. Tihi lanci nemaju ovaj efekt, daju\u0107i zaista gladak omjer brzine i gotovo tihi rad \u010dak i pri brzinama iznad 20 m\/s.<\/p>\n<\/div>\n

\n

Skaliranje optere\u0107enja na osnovu \u0161irine<\/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

Konfiguracije srednjeg i bo\u010dnog vodi\u010da<\/h3>\n

Lanci sa srednjom vodilicom (Middle Guide) koriste centralnu vodilicu koja se kre\u0107e u \u017elijebu na povr\u0161ini lan\u010danika, odr\u017eavaju\u0107i lanac centralno usmjerenim bez bo\u010dnog pomjeranja. Ovo je standardna konfiguracija za ve\u0107inu zatvorenih mjenja\u010da i automobilskih razvodnih mehanizama. Lanci sa bo\u010dnom vodilicom (Side Guide) koriste vodilice na oba vanjska ruba, pogodne tamo gdje se ne mo\u017ee osigurati sredi\u0161nji \u017elijeb. U\u017ee \u0161irine kod EP-SC3 i EP-SC4 koriste bo\u010dnu vodilicu; \u0161iri lanci s vi\u0161e plo\u010da po \u0161irini koriste srednju vodilicu.<\/p>\n<\/div>\n

\n

Mogu\u0107nost velike brzine<\/h3>\n

Tihi lanci EP-SC3 s korakom od 9,525 mm mogu pouzdano raditi pri brzinama lanca iznad 20 m\/s uz pravilno podmazivanje, \u0161to daleko prema\u0161uje prakti\u010dnu granicu valjkastih lanaca s istim korakom. EP-SC4 s korakom od 12,700 mm je predvi\u0111en za brzinu do pribli\u017eno 15 m\/s za kontinuirani rad, a EP-SC5 s korakom od 15,875 mm je pogodan za brzine do 10 m\/s. Ove karakteristike \u010dine tihe lance preferiranim izborom za pogone bregastih vratila velike brzine, pogone generatora i bilo koju primjenu gdje je buka primarno ograni\u010denje.<\/p>\n<\/div>\n

\n

Podmazivanje uljnom kupkom<\/h3>\n

Tihi lanci zahtijevaju kontinuirano podmazivanje uljem, obi\u010dno iz uljne kupke u koju se lanac djelimi\u010dno uranja dok se kre\u0107e oko donjeg lan\u010danika, ili iz prskanja ulja usmjerenog na zonu kontakta lanca i lan\u010danika. Za razliku od valjkastih lanaca koji mogu tolerirati povremenu primjenu ulja u nekim situacijama pri malim brzinama, tihi lanci uvijek zahtijevaju kontinuirani film ulja na zoni bo\u010dnog kontakta. Ulje tako\u0111er obavlja funkciju odvo\u0111enja topline, odvode\u0107i toplinu trenja koja se stvara na spoju bo\u010dnog kontakta tokom rada pri velikim brzinama.<\/p>\n<\/div>\n

\n

Precizni oblik zuba lan\u010danika<\/h3>\n

Tihi lan\u010danici koriste profil zuba ravnog profila pod uglom od 30 stepeni (kao \u0161to je prikazano na crte\u017eu sa dimenzijama na vrhu tabele specifikacija), umjesto evolventnog oblika zuba kao kod lan\u010danika valjkastih lanaca. Profil zuba mora biti precizno obra\u0111en do specificiranog ugla od 30 stepeni i dimenzije h1 (od centra rupe do vrha zuba) za pravilno zahvatanje lanca. Lan\u010danici sa istro\u0161enim, nepravilno obra\u0111enim ili neta\u010dnim profilima zuba uzrokovat \u0107e brzo tro\u0161enje lanca i stvaranje buke. EP mo\u017ee isporu\u010diti uskla\u0111ene lan\u010danike sa provjerenim profilima zuba od 30 stepeni za sve veli\u010dine lanaca SC3, SC4 i SC5.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Aplikacije<\/h2>\n
\n
\n

Pogoni bregaste osovine i razvodnog mehanizma za automobile<\/h3>\n

Lanci EP-SC3 i EP-SC4 se \u0161iroko koriste u pogonima za razvod bregastih vratila automobilskih motora, pogonima pumpi za ulje i pogonima balansnih vratila. Tihi rad eliminira zveckanje lanca razvoda koje poga\u0111a pogone valjkastih lanaca pri hladnom startu, gdje viskoznost ulja odga\u0111a dolazak podmazivanja do lanca. Precizan omjer brzine tihog zahvata lanca tako\u0111er osigurava preciznije razvod ventila u odnosu na alternative valjkastih lanaca, doprinose\u0107i ni\u017eim emisijama i pobolj\u0161anoj ekonomi\u010dnosti goriva na nivou razvoja motora.<\/p>\n<\/div>\n

\n

Industrijski mjenja\u010di i alatni strojevi<\/h3>\n

Lanci EP-SC4 i EP-SC5 su specificirani za zatvorene industrijske pogone mjenja\u010da, pogone vretena alatnih ma\u0161ina i preciznu proizvodnu opremu gdje je buka faktor kvaliteta i regulatorni faktor. Tekstilne ma\u0161ine, \u0161tamparske ma\u0161ine i oprema za pakovanje koriste tihe lance u primarnim pogonima gdje bi buka valjkastih lanaca bila neprihvatljiva za operatere i potencijalno bi maskirala buku mehani\u010dkih kvarova koju timovi za odr\u017eavanje moraju otkriti. EP-SC4 u \u0161irinama od 28,5 mm do 61,5 mm pokriva ve\u0107inu zahtjeva za mjenja\u010de i pogone alatnih ma\u0161ina.<\/p>\n<\/div>\n

\n

Pogoni generatora i kompresora<\/h3>\n

Pogoni generatora i kompresora koji koriste tihe lance EP-SC4 i EP-SC5 imaju koristi od glatkog odnosa brzina, \u0161to smanjuje torzione vibracije koje pobu\u0111uju pogonjenu opremu. U generatorskim primjenama, promjena odnosa brzina pogona valjkastim lancem neznatno modulira izlazni napon i frekvenciju; tihi lanac eliminira ovu modulaciju. U pogonima klipnih kompresora, tihi lanac smanjuje amplitudu torzionog pobu\u0111ivanja u pogonskom sklopu, produ\u017eavaju\u0107i vijek trajanja le\u017eaja i zaptivke vratila u pore\u0111enju s alternativama valjkastim lancima na istom nivou snage.<\/p>\n<\/div>\n<\/div>\n

\nZa\u0161to je tihi lanac ti\u0161i od valjkastog lanca pri istoj brzini?<\/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
\nKoja je razlika izme\u0111u srednjeg vodi\u010da (Middle Guide) i bo\u010dnog vodi\u010da (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
\nKako da odredim ispravnu \u0161irinu lanca za moje potrebe snage?<\/summary>\n
Prvo odaberite korak lan\u010danika (SC3, SC4 ili SC5) na osnovu dostupne veli\u010dine lan\u010danika i brzine lanca. Zatim izra\u010dunajte zategnutost lanca iz prenesene snage: zategnutost (kN) = snaga (kW) podijeljena s brzinom lanca (m\/s). Primijenite faktor servisa za tip pogona (1,0 za glatke, 1,3 za umjerene udare, 1,5 za jake udare) da biste dobili projektiranu zategnutost. Podijelite projektiranu zategnutost s 5 (minimalni faktor sigurnosti za tihe lance) da biste dobili potrebnu minimalnu zateznu \u010dvrsto\u0107u. Prona\u0111ite prvi red u tabeli specifikacija za odabranu seriju koraka gdje Q min (kN) prema\u0161uje ovu potrebnu vrijednost, a to je minimalna \u0161irina lanca za va\u0161u primjenu. Odaberite sljede\u0107u ve\u0107u veli\u010dinu ako je izra\u010dunata \u0161irina na granici kolone Q min.<\/div>\n<\/details>\n
\nKakvo podmazivanje je potrebno za tihe lance?<\/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
\nKoji su znaci da je potrebno zamijeniti tihi lanac?<\/summary>\n
Primarni pokazatelj istro\u0161enosti tihih lanaca je izdu\u017eenje, mjereno kao procentualno pove\u0107anje koraka na dijelu od 10 karika u pore\u0111enju sa nominalnim. Zamijenite lance kada izdu\u017eenje dostigne 1,51 TP3T za precizne pogone (automobilski mjera\u010di vremena, alatni ma\u0161ini) ili 2,01 TP3T za op\u0161te industrijske pogone. Vizuelni znaci koji ukazuju na potrebu zamjene: vidljivo istro\u0161enost na kontaktnim povr\u0161inama boka plo\u010de (polirana ili u\u017eljebljena podru\u010dja na povr\u0161ini od 30 stepeni karika); labavost ili zazor na spojevima klinova iznad onoga \u0161to je tipi\u010dno za novi lanac; lanac se vidljivo vi\u0161e pomjerao na zubima lan\u010danika nego kada je bio nov (\u0161to ukazuje na to da vrh zuba vi\u0161e ne dodiruje dno prozora plo\u010de); ili se buka lanca vratila uprkos pravilnom podmazivanju, \u0161to ukazuje na to da se geometrija kontakta boka istro\u0161ila u odnosu na originalni profil.<\/div>\n<\/details>\n
\nMogu li se tihi lanci rezati na du\u017einu i spajati spojnom karikom?<\/summary>\n
Da. Tihi lanci se re\u017eu na potreban broj koraka i spajaju spojnim klinom. Dimenzija Lc max u tabeli specifikacija je du\u017eina klina za polo\u017eaj spojne karike, koja je ne\u0161to du\u017ea od maksimalne du\u017eine radnog klina L kako bi se prilagodio zadr\u017eavanju rascjepke ili opru\u017ene kop\u010de na krajevima lanca. Prilikom rezanja tihog lanca na du\u017einu, rez mora biti na polo\u017eaju klina, a ne kroz plo\u010du. Broj koraka u krugu mora se odrediti iz sredi\u0161njeg razmaka izme\u0111u lan\u010danika i broja zubaca lan\u010danika, koriste\u0107i standardnu \u200b\u200bformulu za du\u017einu lanca. Za automobilske lance razvodnog mehanizma, du\u017eina je fiksna dizajnom motora i treba je naru\u010diti na ta\u010dan broj karika naveden u servisnom priru\u010dniku motora, a ne izra\u010dunati.<\/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

“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
