1) Description of Gearbox Gear reducers
Gearboxes or also commonly called gear reducers or enclosed speed reducers are used on many
electromechanical drive systems
Gearboxes, are essentially multiple open gear sets contained in a housing. The housing supports
bearings and shafts, holds in lubricants, and protects the components from surrounding conditions.
2) Function of Gearbox Gear reducers
Gearboxes are available in a wide range of load capacities and speed ratios. The purpose of a gearbox
is to increase or reduce speed. As a result, torque output will be the inverse of the speed function.
3) Factors of Gearbox Gear reducers
Gear drive selection factors include: shaft orientation, speed ratio, design type, nature of load, gear rating,
environment, mounting position, operating temperature range, and lubrication. Helical gearboxes and worm
gearboxes are among the more common types for electromechanical drives.
