Gearboxes come in several configurations, each appropriate for somewhat different industrial uses. A gearbox comprising a planetary gear system, which is a particular kind of epicyclical gearing system, has several advantages over the other gear trains as a result of its exceptional solar system like arrangement.

In a planetary gearbox, planetary gears which, subsequently, rotate around the sun gear are encompassed by a ring gear. Straightforward arrangements include only one of each gear component, compound planetary gears use stepped or meshed planet gears to enhance flexibility and torque to weight ratios.

Planetary gearboxes have several advantages over conventional industrial gearboxes. Not only are they exceptionally streamlined, the arrangement permits load distribution over the gears. This distribution allows for a heightened firmness and greater torque capacities, which is critical in many industrial uses. Torque density and load skill both can be improved simply by adding more planet gears to the system.

Possibly, the most attractive feature of a planetary gearbox is its exceptionally high efficiency.

Their compact size, high torque to weight ratios, high efficiency and functional firmness make planetary gearboxes useful across a variety of businesses including steel and metal working, building and chemical and food sectors. In particular, planetary arrangements lend themselves nicely to industrial slewing drives used across all these business sectors.

Some automatic transmission systems operate by putting multiple planet and sun gear components inside the same annuls or ring gear and the input signal of the second stage to join the result of the first stage to be able to improve or decrease the gear ratio.

There are many disadvantages to planetary gear systems although, through intelligent engineering layout these are generally pretty easy to cancel.

Despite their generally complicated layout, gearboxes housing planetary gear systems are popular across automotive, production, building and chemical and food sectors.
