The basic transmission structure of planetary reducer includes sun gear, planetary gear, inner ring gear, connecting gear, planet carrier and output shaft. Its characteristics are large torque, impact resistance, small volume, light weight, high efficiency, small rear clearance, etc. the characteristics and transmission principle of planetary reducer are analyzed in detail below.

1. Characteristics of planetary reducer:

The structure of high torque impact resistant planetary gear is different from the traditional parallel gear. The planetary reducer has a large area of 360 degree load on the gear contact surface. The surfaces of multiple gears jointly and evenly bear the instantaneous impact load, so that it can withstand the impact of large torque, and the body and bearing components will not be damaged due to high load fracture.

Small size and light weight: in the traditional step of gear reducer, multiple groups of large and small gears tend to be staggered transmission to reduce speed. The structure of planetary reducer can be repeatedly connected according to the required number of segments, and the combination of multiple segments can be completed independently. Small size, light weight and light shape make the equipment more valuable.

High efficiency and low backlash: the unique multi-point uniform density in the planetary gear material combination, the arc envelope analysis structure of the outer gear ring, makes the outer gear ring closely connected with the planetary gear, and the tightness between the gears is high. In addition to improving their own extremely high efficiency value of the reducer, the equipment itself can achieve high positioning selection.

2. Transmission principle of planetary reducer: the transmission structure of planetary reducer is the most effective combination of gear reducer at present. The driving source starts the sun gear in a straight line or connection, and the sun gear drives the planet gear combined on the planet carrier to rotate. The whole planetary gear system rotates along the rotation of the outer ring gear, and the planet carrier is connected with the output shaft to reduce the speed. High reduction ratios are accumulated through multiple sets of stage gears and planetary gears.

The above is an introduction of the transmission principle of the planetary reducer. If you need a planetary reducer, please consult the manufacturer of Newgear.
