All types of Gearboxes

– Helical gearbox
Helical gears are similar to spur gears except that their teeth are cut at an angle to the hole (axis) rather than straight and parallel to the hole like the teeth of a spur gear. The line of contact between two teeth is not parallel to the teeth but inclined .
– Planetary gearbox
A planetary gearbox is a gearbox with the input shaft and the output shaft aligned. A planetary gearbox is used to transfer the largest torque in the most compact form (known as torque density).

–Direct shaft gearbox
A DSG gearbox is effectively two gearboxes in one, connected to the engine by two drive shafts. As well as two gearboxes there are also two clutches and both the gearboxes and clutches are operated hydraulically by a mechatronics system (effectively a combination of mechanics and electronics).

–Compound gearbox
A compound gear is a number of gears fixed together. Consequently, they rotate at the same speed. An example can be seen below. The gears that make up a compound gear usually differ in size and have a different number of teeth. This is useful if there is a need to speed up or slow down the final output.

–Cranville pinion gearbox
Pinion gearbox technology is based on spur gearing with two gearing sub-units connected on the output end. The combination of both gearing sub-units with their different gear pairs generates the individual gears.
