The chain is situated 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 tooth that are located in the bottom of the chain. The chain the teeth and the chain wheel teeth are Special Chains china therefore constituted that by wear at the linking components the pitch increases, the chain accordingly have a tendency to re-locate on the tooth surfaces, so to hold on a larger pitch diameter; the consequence of this move can be that the pitch of the chain and the pitch of the wheel enhance to the same degree.
The load on one’s teeth is divided across all the teeth within the contact arc, 
regardless of the extension by wear.
The links do not show any gliding on or of one’s teeth, which carries a soft and practically noiseless gripping; this tranny was also designed for transmitting power or more speeds than this is allowed for roll chains.
The return of the “low noise chain” can amount 99% and for the full transfer from 96% to 97% under favourable conditions; of 94% upto 96% there exists 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 strain arrangement included. At extremely loose chains the balancing of the chain will increase the wear. A good tension arrangement can dual the lifetime. Hook clearance is required with a minimum of +/-3 mm. Although the chain gets higher positioned on the teeth upon stretching of the pitch, this stretching is not moderated by the directly section of the chain, which implies that this section is definitely slacking at wear.
