1) Description of Gearbox Speed Reducers
Gearboxes and speed reducers are enclosed mechanical speed reduction devices commonly
used in today's automation control systems
2) Features of Gearbox Speed Reducers
Gearboxes allow you to increase torque while reducing the speed of your prime mover output shafts.
The output shaft of a gearbox rotates at a slower rate than the input shaft.
This produces a mechanical advantage, which increases torque.
Conversely, your gearbox can be set up to do the opposite, providing an increase in shaft speed
with a reduction in torque
