Gearboxes use gear ratios to provide speed and torque conversion from a source of rotating power to another device.Planetary gear It is a gear system consisting of one or more external gears or planetary gears that rotate around the sun gear or sun gear. Usually, the planetary gear is mounted on a movable arm or bracket, and it can rotate relative to the sun gear. Planetary gear  The system also includes the use of an external gear or ring gear that meshes with the planetary gears.The shafts of all gears are usually parallel, but for special cases such as sharpeners, they can be placed obliquely to introduce the element of bevel gears.

- Planetary gearbox The layout is an engineering design, which has many advantages compared with the traditional gearbox layout.One of the advantages is its unique combination of compactness and excellent power transmission efficiency.Typical efficiency loss Planetary gearbox Only 3% is scheduled for each stage.This type of efficiency ensures that most of the energy input to the gearbox is multiplied and transmitted as torque, rather than wasted on mechanical losses in the gearbox.Another advantage of the planetary gearbox arrangement is load distribution.Since the transmitted load is shared among multiple planets, the torque capacity is greatly improved.The more planets in the system, the greater the load capacity and the higher the torque density.

- Planetary gearbox The arrangement also creates greater stability and higher rotational stiffness.Planetary gearboxes, also called planetary gearboxes, provide more torque through a reduced size motor.This is very useful in applications that require a lot of power but do not have enough space to accommodate the motor.The hybrid motor with planetary gearbox combines the precision of the hybrid motor with the high power size ratio of the planetary gearbox, thereby providing an extremely efficient motor for high-performance work.
