Structural principle of servo planetary reducer

PUHE AF115 method LAN mount servo planetary reducer/low backlash/suitable for 750W.1000W.2000W Structure: planetary gear, sun gear and outer ring gear.
Due to the structure of the planetary reducer, the single-stage reduction is 3 ratios, and the general ratio is not greater than 10. The public ratio is 3.4.5.6.8.10.The number of reducer stages generally does not exceed three levels, but there are some customized reducers with large speed ratios that have four levels of reduction.Compared with other reducers, the planetary reducer has the characteristics of high rigidity, (single stage can achieve less than 1 point), high transmission efficiency (single stage is 97% - 98%), high torque/volume ratio, life-long maintenance-free, etc. etc. Planetary reducers are mainly installed on stepper motors and servo motors to reduce speed, increase torque and match inertia.The transmission mechanism of the planetary gear reducer is a gear.Its structure diagram is very simple.Imagine there are two circles, one big and one small.The two circles are concentric.There are three other small circles in the ring section between the two circles.The larger circle of all the circles is the ring gear, and the other four smaller circles are the gears.The one in the middle is called the sun gear, and the other three small circles are called the planet gears.The servo motor drives the sun gear of the reducer, and the sun gear drives the planet gears supported on the internal gear ring.The planetary gear drives the output shaft connected with the outer gear ring through its meshing transmission with the outer gear ring to achieve the purpose of deceleration.
