What is the function of planetary reducer?

Update:24-10-2022
Summary:...
Planetary gear reducer is a kind of mechanical transmission equipment, which has good performance in reducer and is used in all walks of life; the equipment is mainly composed of planetary gear, sun gear, inner gear, outer ring and planet carrier. Used to reduce speed and increase torque. Compared with the gear reducer, the performance of the planetary reducer is better. Let's take a look at the role of the planetary reducer.

 
1. The planetary reducer consisting of a sun gear system plus a set of live planetary gears (one set is three) can maintain considerable accuracy during the process of telling and running, and the volume of the planetary reducer is relative to its size. The output torque is very small. However, due to the accuracy of its materials and meticulous processing methods, the cost of planetary reducers is much higher than that of gear reducers
2. Some reducers can be found in various mechanical transmission systems, ranging from transport ships, automobiles, locomotives, heavy machinery for construction, bicycles in principle similar to reducers, processing machinery and automated production equipment used in the machinery industry to ordinary of household appliances, clocks, etc. Its application can be seen from the transmission of high power to the transmission of small loads and angles. In industrial applications, the reducer has the function of slowing down and increasing torque.
 
Due to the structure of the planetary reducer, the single-stage deceleration is less than 3, generally not more than 10. The general reduction ratio is 3/4/5/6/8/10, and the reducer series generally does not exceed 3. However, some large reduction ratios have 4-stage reduction compared to custom-made reducers. Compared with other reducers, planetary reducers have high rigidity, high precision (single stage within 1 minute), high transmission efficiency (single stage is 97%-98%), high torque/volume ratio and lifetime maintenance-free. Features. For these reasons, planetary reducers are mainly installed on stepper motors and tool post motors for reducing speed, increasing torque and matching inertia. The rated input speed of the planetary reducer can reach 18000rpm (related to the size of the reducer itself, the larger the reducer, the smaller the rated input speed), and the working temperature is generally around -25 to 100 degrees, which can be changed by replacing the grease.
