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

St\u00e4ndig kraft flankkontakt tysta kedjor<\/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

Tv\u00e5 guidekonfigurationer \u00e4r tillg\u00e4ngliga. Mellanguiden (Mellanguiden)<\/strong> anv\u00e4nder en styrplatta i mitten av kedjebredden, som l\u00f6per i ett sp\u00e5r som \u00e4r fr\u00e4st in i mitten av kedjehjulet. Detta \u00e4r standardkonfigurationen f\u00f6r de flesta industriella v\u00e4xell\u00e5dor och transmissionsapplikationer f\u00f6r fordon. Sidostyrning (Sidostyrning)<\/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

De inverterade kuggplattflankerna griper in i kedjehjulets kuggflanker i en glidande kontaktverkan som eliminerar den cykliska hastighetsvariationen (kordverkan) som finns i alla rullkedjedrifter. I en rullkedja varierar kedjehastigheten sinusformat n\u00e4r varje rulle kommer in i och l\u00e4mnar kedjehjulets kuggutrymme; denna variation \u00f6kar med kedjehastigheten och \u00e4r den prim\u00e4ra k\u00e4llan till rullkedjebuller och vibrationer vid h\u00f6g hastighet. Tysta kedjor \u00e4r fria fr\u00e5n denna effekt, vilket ger ett verkligt j\u00e4mnt hastighetsf\u00f6rh\u00e5llande och n\u00e4stan tyst drift \u00e4ven vid hastigheter \u00f6ver 20 m\/s.<\/p>\n<\/div>\n

\n

Breddbaserad lastskalning<\/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

Konfigurationer f\u00f6r mittstyrning och sidostyrning<\/h3>\n

Mellanstyrningskedjor (Middle Guide) anv\u00e4nder en central styrplatta som l\u00f6per i ett sp\u00e5r i kedjehjulets yta, vilket h\u00e5ller kedjan centralt sp\u00e5rad utan sidodrift. Detta \u00e4r standardkonfigurationen f\u00f6r de flesta slutna v\u00e4xell\u00e5dor och transmissionsv\u00e4xlar f\u00f6r bilar. Sidostyrningskedjor (Side Guide) anv\u00e4nder styrplattor i b\u00e5da ytterkanterna, l\u00e4mpliga d\u00e4r ett mittsp\u00e5r inte kan tillhandah\u00e5llas. De smalare bredderna i EP-SC3 och EP-SC4 anv\u00e4nder sidostyrning; bredare kedjor med fler plattor \u00f6ver bredden anv\u00e4nder mittstyrning.<\/p>\n<\/div>\n

\n

H\u00f6g hastighetskapacitet<\/h3>\n

EP-SC3 tysta kedjor med 9,525 mm stigning kan fungera tillf\u00f6rlitligt vid kedjehastigheter \u00f6ver 20 m\/s med korrekt sm\u00f6rjning, vilket vida \u00f6verstiger den praktiska gr\u00e4nsen f\u00f6r rullkedjor med samma stigning. EP-SC4 med 12,700 mm stigning \u00e4r klassad f\u00f6r upp till cirka 15 m\/s f\u00f6r kontinuerlig drift, och EP-SC5 med 15,875 mm stigning \u00e4r l\u00e4mplig f\u00f6r hastigheter upp till 10 m\/s. Dessa egenskaper g\u00f6r tysta kedjor till det f\u00f6redragna valet f\u00f6r h\u00f6ghastighetskamaxlar, generatordrifter och alla till\u00e4mpningar d\u00e4r buller \u00e4r en prim\u00e4r begr\u00e4nsning.<\/p>\n<\/div>\n

\n

Sm\u00f6rjning av oljebad<\/h3>\n

Tysta kedjor kr\u00e4ver kontinuerlig oljesm\u00f6rjning, vanligtvis fr\u00e5n ett oljebad d\u00e4r kedjan delvis s\u00e4nks ner n\u00e4r den r\u00f6r sig runt det nedre drevet, eller fr\u00e5n en oljespray riktad mot kedjans och drevens ingreppszon. Till skillnad fr\u00e5n rullkedjor som t\u00e5l intermittent oljep\u00e5f\u00f6ring i vissa l\u00e5ghastighetssituationer, kr\u00e4ver tysta kedjor alltid en kontinuerlig oljefilm vid flankkontaktzonen. Oljan utf\u00f6r ocks\u00e5 v\u00e4rmeavledningsfunktionen genom att leda bort friktionsv\u00e4rmen som genereras vid flankkontaktgr\u00e4nssnittet under h\u00f6ghastighetsdrift.<\/p>\n<\/div>\n

\n

Precisionskugghjulets tandform<\/h3>\n

Tysta kedjehjul anv\u00e4nder en 30-graders raksidig tandprofil med inkluderad vinkel (som visas i m\u00e5ttritningen h\u00f6gst upp i specifikationstabellen) ist\u00e4llet f\u00f6r den evolventa tandformen hos rullkedjehjul. Tandprofilen m\u00e5ste bearbetas exakt till den angivna 30-graders vinkeln och h1-dimensionen (h\u00e5lets centrum till tandspetsen) f\u00f6r korrekt kedjeingrepp. Kedjehjul med slitna, felbearbetade eller felaktiga tandprofiler orsakar snabbt kedjeslitage och bullergenerering. EP kan leverera matchande kedjehjul med verifierade 30-graders tandprofiler f\u00f6r alla SC3-, SC4- och SC5-kedjestorlekar.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Applikationer<\/h2>\n
\n
\n

Kamaxel- och timingdrivningar f\u00f6r fordon<\/h3>\n

EP-SC3 och EP-SC4 kedjor anv\u00e4nds ofta i kamaxeltransmissioner, oljepumpstransmissioner och balansaxeltransmissioner i bilmotorer. Den tysta driften eliminerar det skrammel som drabbar rullkedjetransmissioner vid kallstart, d\u00e4r oljeviskositeten f\u00f6rdr\u00f6jer sm\u00f6rjningen som n\u00e5r kedjan. Det exakta hastighetsf\u00f6rh\u00e5llandet vid tyst kedjeinkoppling ger ocks\u00e5 en mer exakt ventilstyrning \u00e4n rullkedjealternativ, vilket bidrar till l\u00e4gre utsl\u00e4pp och f\u00f6rb\u00e4ttrad br\u00e4nsleekonomi vid motorutvecklingsniv\u00e5.<\/p>\n<\/div>\n

\n

Industriella v\u00e4xell\u00e5dor och verktygsmaskiner<\/h3>\n

EP-SC4- och EP-SC5-kedjorna \u00e4r specificerade f\u00f6r slutna industriella v\u00e4xell\u00e5dsdrifter, spindeldrifter f\u00f6r verktygsmaskiner och precisionstillverkningsutrustning d\u00e4r buller \u00e4r en kvalitets- och regulatorisk faktor. Textilmaskiner, tryckmaskiner och f\u00f6rpackningsutrustning anv\u00e4nder alla tysta kedjor i prim\u00e4ra drivningar d\u00e4r rullkedjebuller skulle vara b\u00e5de oacceptabelt f\u00f6r operat\u00f6rer och potentiellt maskera mekaniskt felbuller som underh\u00e5llsteam beh\u00f6ver uppt\u00e4cka. EP-SC4 i bredderna 28,5 mm till 61,5 mm t\u00e4cker majoriteten av kraven f\u00f6r v\u00e4xell\u00e5ds- och verktygsmaskindrift.<\/p>\n<\/div>\n

\n

Generator- och kompressordrivningar<\/h3>\n

Generatordrifter och kompressordrifter som anv\u00e4nder tysta kedjor EP-SC4 och EP-SC5 drar nytta av det j\u00e4mna hastighetsf\u00f6rh\u00e5llandet, vilket minskar torsionsvibrationer som exciterar den drivna utrustningen. I generatortill\u00e4mpningar modulerar hastighetsf\u00f6rh\u00e5llandet fr\u00e5n en rullkedjedrift utsp\u00e4nningen och frekvensen n\u00e5got; tysta kedjor eliminerar denna modulering. I kolvkompressordrifter minskar tysta kedjor amplituden av torsionsexcitationen i drivlinan, vilket f\u00f6rl\u00e4nger lagrens och axelt\u00e4tningarnas livsl\u00e4ngd j\u00e4mf\u00f6rt med rullkedjealternativ med samma effektniv\u00e5.<\/p>\n<\/div>\n<\/div>\n

\nVarf\u00f6r \u00e4r en tyst kedja tystare \u00e4n en rullkedja vid samma hastighet?<\/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
\nVad \u00e4r skillnaden mellan mittenstyrning (Middle Guide) och sidostyrning (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

\nVilken sm\u00f6rjning kr\u00e4vs f\u00f6r tysta kedjor?<\/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

“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
