A cog ordinarily refers to a solitary tooth on a equipment. In the context of gears, a cog is 1 of the individual tooth that make up the equipment mechanism. Gears consist of multiple cogs or tooth that mesh with each other to transmit electrical power and movement.
So, to be clear, a cog is not a independent part or component unique from a equipment. As a substitute, it is a term that specially refers to an individual tooth on a equipment. Gears are made up of numerous cogs, and these cogs work with each other to sort the complete gear mechanism.
When speaking about gears, it is typical to refer to the collective arrangement of cogs or enamel on a China gear instead than focusing on unique cogs. However, in selected contexts, the expression “cog” may well be employed to explain an person tooth or the toothed portion of a equipment.
