A planetary gear is a type of gear that includes a central gear, known as the sun gear, and acts as the input gear. It is an instrument with the output and input shafts aligned. It is employed to transmit the greatest torque in the most compact form.
Planetary gearboxes are stronger than spur and helical gears because they do not require a separate transmission shaft or flywheel to transfer forces. Planetary gears have a wide angle of revolution.
Planetary gearboxes also have a high torque transmitting capacity due to the distribution of the load across several planets, making them stable and long-lasting. They are also highly efficient, with low power losses and transmission efficiency up to 98% for the first stage of the gearbox.
Planetary gears are characterised by their high level of efficiency; they also display a high power density in comparison to other types of gears, due to their compact construction. The use of the external ring gear in particular reduces both the volume and mass of this type of gear.
