B Notation

Forms and proportions of spur gears for instruments and clockwork mechanisms from 0.070 modules to 1.000 module. Provisions for contrate gears, derivation of cycloidal gears (where the wheel drives the pinions), tolerances.

This part applies to cycloidal type spur gears for spring or weight-driven mechanisms in which:

the pinion is the driven member, or
the pinion is required to act sometimes as the driver and sometimes as the driven member.

For integrating electricity meters the particular form of gear specified herein is not necessary and it is recognised that other existing forms of gear will continue to be used.
