More broadly, the fundamental, interacting component within any complex system or sequence of events (figuratively).
Dialectal Variation
British vs American Usage
Differences
No significant lexical difference; both use 'gearwheel'. British English might use 'cogwheel' marginally more often in non-technical contexts. The spelling 'gear wheel' (open compound) is equally acceptable in both varieties.
Connotations
Identical technical connotations. The figurative sense ('a mere gearwheel in the machine') is equally common and carries the same slight negative nuance of disposability in both cultures.
Frequency
Low frequency in everyday speech in both regions. Slightly higher frequency in specific manufacturing, engineering, and hobbyist contexts (e.g., clockmaking, robotics).

No, 'gearwheel' is exclusively a noun. The related verb is 'to gear' (as in 'to gear up' or 'geared towards').
No, it is a low-frequency, technical term. You will encounter it in engineering, mechanics, and figurative language, but rarely in daily conversation.
