Campagnolo key ring.

from the 80's, lever, when the italian's owned the industry

Chainwheel is common as you say, I think "wheel" is maybe used for multiples or trains of? Quite interesting though.

it's also used in watches, but they are cogs. just to confuse things.

you need to come in to the inner, you'll need something far harder after that.

LSD and blotting paper would do, but the bike' pulled me out of that mess • long ago

Maybe up to the 70s but not after. People soon worked out it wasn't japcrap.

or a wheel.

Chainwheel - traditionally used on the chainset on a bicycle

and sprocket, usually referring to the rear wheel mounted driver/s

A gear has teeth cut to mesh with another gear.

Your sturmey hubs have gears in them, but a sprocket on the outside, meshing with a chain, driven by a chain wheel.

The term "gear" is used to refer to the drive ratio, but then when people say they have five gears, they assume that the five sprockets on the back are called gears.

Of course the true pedant might prefer to use the term "speed" to refer to the drive ratio.
(Pretty common now eg with 11- speed cassettes)

Or maybe not

from an engineers point they are all wheels except a gear (unless it's a gear wheel which is a wheel with inserted teeth rather than cut).

a gear may not only mesh with another gear, it may also mesh with a worm (I'm being humorous here in case you missed it)

I thought a worm was a type of gear though

that's the bit I was referring to in parenthesis I knew you'd miss it, my humour is good it goes over peoples heads all the time.
