The main task of the timing chain journey is come ensure the opening and also closing that the valves in the cylinder head.

You are watching: Which timing chain type is also called a silent chain

Not every timing chains are the same: there space a variety of varieties that different in shape and design relying on the requirements and also load the the individual electric motors in i m sorry they are used. Here, we would prefer to introduce the most vital ones.

Roller Chains

The roller chain is the most renowned chain used and also offers one ideal combination of strength and also NVH performance. The inner attach of a roller chain is composed of 2 inner lobes, two sleeves pressed into the connect eyes, and two rollers rotating over the sleeves.

Roller Chain

Bush Chains

With the bush chain, the 2 rollers room dispensed so the sleeves are correspondingly enlarged in diameter and also are straight engaged through the sprocket. Sleeve chains have actually a bigger joint surface ar than equivalent roller chains. shrub chains provide excellent strength and wear power in high fill conditions and also are greatly used in rapid running diesel engines.

Toothed Chains

The special design of this steel connect chain is the toothed chain – additionally known as a silent chain. The middle and also inner lugs are developed to carry out exceptional infection force between the chain and sprocket. toothed chains offer wonderful NVH power with amplified durability characteristics.

Toothed Chains

Combination the Toothed and Sleeve Chain

Due to your kinetic behaviour, toothed chains have a high potential for enhancing dynamic and acoustic properties. While toothed chain drives have actually been used for countless years in lightly invited timing chain drives, they have actually not yet been provided in much more heavily invited engines because of the bigger chain length compared to shell and also roller chains.

In the new chain type of the toothed/sleeve combination, one optimized kinematic movement sequence in ~ the inlet and also outlet that the chain into the sprocket has actually made a reduced height the the inlet impulse possible. This likewise includes the non-uniformity that the movement and also force transmission.

In stimulate to boost the stay behaviour,a sleeve was combined into the tooth lugs that the within member. Whereas thearticulation motion takes location at the inlet and also the outlet into the sprocketbetween the tooth plate and the bolt in the situation of traditional toothed chains,the process takes place in between the sleeve and also the stud in this chain variant.
