What is gear grease called? I'm talking about the common grease
that's used to lubricate gears. It's usually a glob stuck someplace
on the gears. I guess over time it works its way into the gears. In
any case, it's thick grease. Anybody know specifically or keywords
that I can look for?

What speed? What temperature range? What size of gears? What
material are the gears (cast iron, steel, aluminum, bronze, brass,
plastic)? (Hope that it is *not* aluminum working on aluminum!) What
kind of load is applied to the gears (really high loads requires a high
pressure lubricant)? Fully enclosed? Straight tooth, bevel or
herringbone tooth, worm, or a hypoid gear like between the driveshaft
and differential ring gear in an automotive differential?

The reason you can't find much with just a search on "gear
grease" is that there are too many specialized versions for different
applications. A grease which would work fairly well on the thread
changing gears on a lathe would be deadly in a differential (which, like
an automotive transmission, requires a specialized *oil*, not a grease.

For that matter -- there are specialized greases which are *not*
for lubrication at all, such as high vacuum grease.

Give us a bit more information, and likely someone here will be
able to answer you properly.

Good Luck,
DoN.
