The chain is located at the external surface 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 teeth and the chain wheel teeth are so constituted that by use at the linking components the pitch raises, the chain accordingly tend to move out on the tooth areas, so to grasp on a larger pitch diameter; the result of this move is certainly that the pitch of the chain and the pitch of the wheel Special Chains china increase to the same degree.
The load on one’s 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 the teeth, which carries a soft and practically noiseless gripping; this tranny was also manufactured 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 entire transfer from 96% to 97% under favourable conditions; of 94% upto 96% there exists a guarantee with well designed transmission under average operating conditions.
The lifetime and maintenance of low noise chains depends mainly 
on the design of the entire chain drive, the strain arrangement included. At extremely loose chains the balancing of the chain will speed up the wear. A good tension arrangement can double the lifetime. A slight clearance is necessary with a minimum of +/-3 mm. Although the chain is getting higher positioned on the teeth upon stretching of the pitch, this stretching isn’t moderated by the straight portion of the chain, which implies that this section is usually slacking at wear.
