Industrial gearboxes are available in varying types with the most common being Helical, Coaxial helical inline, Bevel helical, Skew bevel helical, Worm reduction and Planetary.
As an enclosed system that transmits mechanical energy to an output device, gearboxes are responsible for a number of attributes that convert energy into a format that is useable.
Helical gears are cut at an angle so that when the teeth engage the gears rotate, creating a smooth and quiet gear. Bearings within the gear support the thrust load and rotation can be adjusted by 90 degrees.
The drive shaft and the output shaft are on the same rotational axis of a Coaxial Gearbox (also known as an inline gearbox) and are usually in the form of spur gears. The spur gears are fixed and parallel to each other.
A Planetary gearbox is similar to a Coaxial Gearbox with the main difference being that not all the axes are fixed. A number of spur gears run between the internal and external teeth in concentric orbit.
A Bevel Gearbox transmits, splits and distributes the power of a singular rotating drive shaft (mechanical) through a specific angle (normally 90 degrees). They are single-stage units that are normally supplied with gear ratios.
A Skew Gearbox is usable in heavy load applications and can be customisable dependant on the number of gears and teeth required. It is a monolithic and rigid structure that is non-parallel with non-intersecting shafts.
Worm reduction gearboxes are used when there is a need for speed to be reduced. The worm meshes with the teeth on the peripheral. These type of gearboxes tend to be used in industries such as fertilizers and minerals.
