The chain is situated at the external surface area of the wheel, equal a belt, and the teeth stick beyond your 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 therefore constituted that by put on at the linking elements the pitch increases, the chain accordingly tend to re-locate on the tooth surfaces, so to grip on a larger pitch diameter; the consequence of this move is definitely that the pitch of the chain and the pitch of the wheel boost to the same level.
The load on the teeth is divided across all the teeth within the contact arc, whatever 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 manufactured for transmitting power or more speeds than this was 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 Special Chains china lifetime and maintenance of low noise chains depends mainly on the design of the entire chain drive, the tension arrangement included. At extremely loose chains the balancing of the chain will speed up the wear. A good tension arrangement can dual the lifetime. A slight clearance is necessary with a minimum of +/-3 mm. Although the chain gets higher positioned on 
one’s teeth upon stretching of the pitch, this stretching is not moderated by the directly section of the chain, which implies that this section is certainly slacking at wear.
