2. Power transmission
Power transmission is the most common function of mechanical chains. It involves driving a sprocket on a driven shaft from a pinion on a motor shaft that is more or less distant from, but parallel to, the driven shaft.
For a given value of the power to be transmitted P = C ω, we can find all possible combinations between a low torque C at high speed ω and a high torque at low speed.
Power transmission is the preferred application for mechanical roller chains, particularly precision short-pitch chains well suited to high speeds, although this notion of speed must obviously be put into perspective in relation to the size and weight of the chains.

Standardization
Since 1989, a great deal of work has been carried out on power transmission standards with a dual focus:
a desire to extend ISO international standardization to all countries. ISO Technical Committee 100 seeks a compromise acceptable to all. As a result, France is gradually replacing its national mechanical chain standards with international standards:
