Features and application of planetary gearbox
The planetary gearbox is also called the gearbox. Its structure is a mechanism in which multiple planetary gears rotate around a sun gear. It is also a mechanism that reduces the transmission speed ratio while increasing the torque of the motor proportionally.
Compared with similar ordinary tooth physics box, it has smooth transmission, large bearing capacity, large transmission ratio in small space, especially life. If the gear is made of steel, the service life can reach 1000Y, the volume is small and the appearance is beautiful.
Planetary gearbox is widely used. It was originally used in conjunction with the motor. In addition to the miniature reduction motor, it is also used in the sunshade industry, office automation, smart home, production automation, medical equipment, financial machinery, game consoles and other fields. Such as automatic curtains, smart toilets, lifting systems, currency counters, advertising light boxes and other industries.
The planetary gearboxes on the market mainly have diameters of 16MM, 22MM, 28MM. 32MM, 36MM, 42MM, which are matched with the motor. Its function can reach the load torque: 50KG 1-30W and load speed: 3-2000RPM.
Transmission ratio calculation: planetary gearbox: first level: i=(number of teeth of internal gear/number of teeth of sun gear)+1
