It's a sprocket, not a cog!!!
Does anybody else get annoyed by this?
No. I learnt mechanics on technic lego where the exact same parts could be cogs, sprockets or pinion wheels depending on what you mated them to.
Someone needs to tell all those charlatans selling “chainrings” and “chainwheels” (shimano iirc) about this too then. 😉Posted 4 years ago
Shermer75, it must be so tiring being a beacon of correct mechanical nomenclature. I trust that you also also:
-know your spindles from your axlesPosted 4 years ago
-say Dérailleur not mech, and pronounce the double l properly.
-bleed your brakes from the reservoir or master cylinder not the lever
-say ‘ferrule’ not ‘end cap’
-only refer to an allen key if its manufactured by Allen
-talk of ‘chain bushing wear’ not “stretch”.
-have absolutely no adjustable wrenches in your home or workplace. 😉wobbliscottMember
Cog is a generic term. A Pinion is a specific type or subset of Cogs i.e. as in Rack and Pinion steering. As is an idler. You don’t have pinions in chain drive trains. I would say they are sprockets. But its just splitting hairs. On my first day as an Apprentice we were told there is no such thing as a Drill Bit. Its a Drill, as is the machine that drives it, but is preceded by antoher work like Pillar Drill, or Hand Drill, and if any of us were caught calling it a Drill Bit we go a good bollocking.Posted 4 years agorp16vMember
currentley giggling away at the monitor as the wharehouse lad looks at me like a t*^t… so whare douse a 1pc driver sit in this equasion is it a driver or a sprocket…. also on a belt drive would that then be a cog as not used with a chain or still sub catagorised at sprocket?

I was under the impression that belts went around pulleys. (Well they do on line shafts).
Wasn’t the petard the charge in the mine placed under the enemies walls prior to effecting a breach? To be hoist by the petard was due to incorrect fuse length leaving insufficient time to retreat to a safe distance.Posted 4 years ago
