  Howstuffworks "How Gears Work"
Gears are used in tons of mechanical devices.
With a gear reduction, the output speed can be reduced while the torque is increased.
For instance, in the differential between the rear wheels of your car, the power is transmitted by a shaft that runs down the center of the car, and the differential has to turn that power 90 degrees to apply it to the wheels.

 GEAR BOX GUIDED TOUR   (Site not responding. Last check: 2007-09-15)
Since the worm is fixed in position longitudinally but the worm gear is free to rotate, the worm gear turns, turning the axle and the wheels.
However, as the worm gear turns, its (the train's) resistance to being moved causes the worm gear to tend to push the worm backward if the train is going forward, and forward if the train is going backward.
Note that the forces that push the worm away from the worm gear are shear forces on the shafts of the screws, rather than shear forces on the threads of the screws that retain the bottom on conventional gearboxes.

 Gear Box Monitoring
Gearboxes are often a high maintenance source due to loading from the machine being driven, excessive loading on the gear teeth, and improper alignment of the gearbox to the motor.
Monitoring a gearbox is accomplished by installing an accelerometer on each of the bearing housings for each shaft (4 bearings for a two gear system, 6 for a three gear system etc...).
This application requires the use of proximity probes because vibration is poorly transmitted to the bearing caps of journal bearings.
