The chain is located at the external surface area of the wheel, equal a belt, and the teeth stick outside the chain. The chain grips with the wheel through the teeth that are located at the bottom of the chain. The chain tooth and the chain wheel tooth are so constituted that by use at 
the linking components the pitch improves, the chain accordingly have a tendency to re-locate on the tooth areas, so to grasp on a more substantial pitch diameter; the result of this move can be that the pitch of the chain and the pitch of the wheel enhance to the same extent.
The load on one’s teeth is divided across all of the teeth within the contact arc, whatever the extension by wear.
The links do not display any gliding on or of the teeth, which carries a soft and practically noiseless Special Chains china gripping; this transmitting was also manufactured for transmitting power or higher speeds than this is allowed for roll chains.
The return of the “low noise chain” can amount 99% and for the entire transfer from 96% to 97% under favourable conditions; of 94% upto 96% there is a guarantee with well designed transmission under typical operating conditions.
The life time and maintenance of low noise chains depends mainly on the look of the entire chain drive, the tension arrangement included. At very loose chains the balancing of the chain will increase the wear. A good tension arrangement can dual the lifetime. A slight clearance is necessary with at the least +/-3 mm. Although the chain is getting higher positioned on one’s teeth upon stretching of the pitch, this stretching isn’t moderated by the directly section of the chain, which means that this section is definitely slacking at wear.
