girth & pinion gear
girth & pinion gear
(OP)
reading an article, I've come across the term "girth & pinion gear". Need to translate it into Russian properly (by the way I'm Russian). Could you help me by explaining what it is? most confused with the word "girth" :(
Thanx in advance,
Dmitrii

RE: girth & pinion gear
I have heard of girth and pulley that
was use in old hand equipment. The
girth was a leather strap that moved the
pulley that moved the carriage in a hand
press. Maybe the pulley had teeth in it
that rolled in a rack. Interesting question!
RE: girth & pinion gear
Can you tell us where the article is, and what it is about? The context might offer some clues. I suspect that "girth" in this article is equivalent to "ring" in more common usage, but that's just a guess.
RE: girth & pinion gear
More context (from different articles):
The drier was fired by hot air generated by a kiln which ran above the drier. Unit is _girth/pinion driven_ and lifter bars and still in the shell. Gears on the _girth & pinion_ are fairly worn.
_Girth/pinion driven_, no drive shaft, unit is pulley driven from the motor to the pinion. White metal bearings, trommel discharge, shell is rivited and ±15mm thick on average, mill is complete with the pedistals and bearings _Girth and pinion gears_ are in a very good condition.
All three grades provide lubrication for mining equipment including: _girth and pinion gears_ on rod and ball mills; rack and pinion gears on shovel dipsticks; and swing and pinion gears on top of the lower frame of shovels and draglines, which are sometimes served with an automatic lubrication system.
RE: girth & pinion gear
I think you are right in that it probably
means carrier or surrounding gear or
an internal gear and drive pinion. Girth
can mean waist or surround from the dictionary.
It was actually the dictionary that used
girth and pulley. Webster Dictionary I believe.
RE: girth & pinion gear
I believe, ring and pinion gears are used in cars.
Girth and pinion gears, however, have smth. to do with mills, kilns and the likes.
still not clear why different terms are used. I mean girth vs. ring.

Rotary Kiln Girth Gear
The manufacture of large diameter/ large module girth gears through the conventional methods is not only time consuming but also require large gear cutting machines. The girth gear of rotary kiln is of 6384 mm OD having 56 module and 112 teeth. It was impossible to manufacture this through the conventional methods of gear cutting. TGS arrived at a noble idea of cutting teeth using face mill cutter on a horizontal boring machine. The teeth of the above girth gear were made in 3-4 passes using straight-sided face milling cutter after roughing out the teeth. Since, the diameter of the girth gear was large, the deviations of the involute profile from the straight-sided basic rack profile were minimal and hence a close approximation could be made. The time taken for the teeth cutting was nearly one-third of the time taken generally through the conventional method. The girth gear was put in operation and is working very satisfactorily with good teeth contact.

RE: girth & pinion gear
how about "zubchatyi venets" for girth gear. Is it the translation?
