The planetary gearbox, compared to the cylindrical gear, is characterized by small dimensions in relation to the transmitted torque and high resistance to overload and impact work.
Planetary gears are also known as planetary gears, mainly used in industry due to their high strength and low weight compared to conventional gears, with the same output parameters.
he planetary gear is used in machine rotation drives (for example excavators, wind farms and cranes) where low turnover and compact dimensions are needed. The nature of the work of this type of machines provides impact loads and here the advantage of this type of gear is based on the distribution of the torque transmitted to several parallel gears - as many satellites are installed. In order to achieve large output moments in large machines, several planetary gear stages (two or three) are used as one unit, so the transmission ranges up to several hundred.
