All gearboxes work the same way: there is a gear on the motor, a gear on the thing you're trying to drive, and sometimes a set of gears between the two. The ratio between the gears, plus the RPM of the motor, determines the speed of the workpiece. If the gear on the motor is larger than the gear on the workpiece the RPM of the workpiece will be higher than the speed of the motor. If the workpiece's gear is larger, the workpiece will turn slower than the motor. Given that, though, I've never seen a gearbox on a wood lathe. Wood lathes use belt drive for two reasons, the most important being safety--if you get a catch, a workpiece on a belt driven lathe won't damage you as badly as a workpiece on a gear-driven lathe. Also, belt drive won't feed vibration from the workpiece back into the motor and damage the bearings. Gear drive is used on metal lathes.

How are spindle speed changed in the lathe machine?
Using geared head for gear box driven or stepped pulley if belt driven
What simple machine is a engine?
Gears working together can be a simple machine in themselvesA Gear Train is a complex machine made up of wheel, axles and gears
What is an all gear lathe?
A lathe in a small wood or metal shop has a motor that connects to the lathe by belt. In a "direct drive" lathe the motor connects directly. I assume that "all gear" means direct drive, no belt. A belt drive protects the motor from damage and reduces vibration of the lathe. In addition, the belt allows you to change the gear ratio and thus the speed of the lathe without changing the motor speed. Belt drive is superior in terms of both performance and longevity.

What are application of reverted gear train?
Type your answer here...These are used in speed reducers, clocks and machine tools.
What is the deferent between gear and gear train?
When gear is explained in connection with gear train, it is an individual member of a gear train. That is a gear train a power transmision system containing two or more gears.
What is back gear attachment in lathe?
The back gears on a lathe can be changed to enable it to cut an even wider variety of thread pitches.
How does a gear train work?
A number of gears grouped into a single unit is called 'gear train'.If two gear's in mesh eg, a drive gear and a driven gear also constitute a gear train which are called simple gear train and in the simplest form.simple gear train may have more than two gear's.compound,epicyclic,reverted are some other types of gear train's.
What is the use of back gear arrangement in a lathe headstock?
The back gears on a lathe can be changed to enable it to cut an even wider variety of thread pitches.
What is the difference between a milling machine and a lathe?
A milling machine basically look like a drill press, but with the ability to move the work piece sideways. A lathe clamp and spin the work piece horizontally and use a stationary tool bit to cut and shape the work piece.
What is simple gear train and compound gear train?
A simple gear train is basically the same as a compound gear train, but the compound gear train usually has more gears closer together. Hope this was useful, and way better than the previous answer (ha ha!! I'm looking for that too! tell me when you find out!!).
What type of gear train is used in automatic transmission of an automobile?
epicyclic gear train
