The structure and components of the planetary gear reducer

Planetary gear reducer: main transmission structure: planet, sun gear, outer ring gear.
Due to structural reasons, the planetary gear reducer has three small single-stage reducers, usually no more than 10. The common reduction rate is 3.4.5.6.8.10.The series of reducers are usually no more than 3, but some of them are much lower than the user-defined 4-stage reducer.
Compared with other reducers, planetary reducers have high rigidity, high precision (capable of completing a single stage within 1 minute), high efficiency (97% - 98%), high torque, lifetime protection, etc.
Due to these functions, most planetary reducers are installed in stepper motors and servo motors for speed reduction, improved torque and inertia matching.
The reducer with large external input is 18000 rpm (the same size as its own reducer, and the reducer with large external input has a small speed).The output torque of the industrial planetary gear reducer reaches 2000nm, especially 10000nm, which is suitable for large torque reducer.The working temperature is -25°C to 100°C, which can be changed by changing the working temperature of the grease.
Series: Planetary Gear Units.Because planetary gears need to meet large transmission ratios, sometimes 2 or 3 sets are required to meet the support required for large transmission ratios required.As the number of planetary gears and gearboxes with 2 or 3 stage lengths increases, the progress in efficiency will decrease.
Return Distance: Additional torque will be fixed at the output, clockwise and counterclockwise to allow +- 2% torque on the input.The small angular displacement of the input end of the gearbox and the angular displacement is the spatial return.The unit is 'minutes', which is a 60. Some people call it a bounce.
Planetary controller pin gear reducer: All actuators can be divided into three parts: input part, slow part and output part.The input shaft is still at 180° of the double biased sleeve.There are two roller bearings called swivel arms in an offset setup to form an H configuration.The center holes of the two cycloid gears set the raceway around the rotating arm, which is offset in the ring gear set which meshes with each other through the cycloid gear and the pin gear set to form a tooth difference built-in meshing reduction organization and teeth (In reduced friction and proportional reducers, the pinhead teeth are connected to the pintooth sleeve) The input shaft and migraine sleeve are rolled for one turn.Due to the nature of the profile curve of the teeth on the cycloidal wheel and the constraints of the pin teeth on the pin, the movement of the cycloidal wheel has become these two rotational speeds.As the input shaft rotates, some of the planar motion turns to the stone, and the offset head sleeve also rolls for one revolution.Cycloidal wheels roll in opposite directions.Need to decelerate a tooth, and then combined with W output organization to reduce the speed of the cycloid wheel, the speed rotary motion passes through the pin shaft and is transmitted to the output shaft to obtain a lower output speed.
