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

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

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

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

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

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
