Precision planetary gearbox structure, principle and parameters and applications
Precision planetary gearbox is a planetary reducer with higher precision level, compared with gear motor, DC reducer, gear reducer, precision planetary gearbox’s precision, manufacturing process, technical content, driving efficiency, cost and application range are much; with the industrial society’s pursuit of quality, the popularity of precision planetary gear motor is becoming more and more common.
1.Precision planetary gearbox structure composition
The main components of the precision planetary gearbox consist of planetary wheel, sun wheel, inner gear ring, drive shaft, box, motor (motor) combination. Planetary reducer according to the number of stages are divided into: primary, secondary, tertiary precision planetary reducer.
2. Working principle of precision planetary reducer-how does a planetary gearbox work
Working principle: When the sun wheel rotates under the drive of the motor, the occlusion with the planetary wheel prompts the planetary wheel to produce rotation, and at the same time, because the planetary wheel has another side and the occlusion of the annular inner gear ring on the inner wall of the planetary reducer shell, finally, under the driving force of rotation, the planetary wheel will roll on the annular inner gear ring in the same direction as the rotation of the sun wheel, forming the rotation around the sun wheel.
The planetary wheel will roll on the ring inner gear ring in the same direction as the rotation of the sun wheel, forming a “revolution” movement around the sun wheel. Usually, each planetary reducer will have multiple planetary wheels, which will rotate around the central sun wheel simultaneously under the action of the input shaft and the sun rotation drive, and share and transmit the output power of the planetary reducer.
3.Precision planetary gearbox parameters
Precision planetary reducer is divided into high-power reducer and low-power reducer according to the power size. Micro precision planetary reducer has the characteristics of rigidity, driving accuracy, torque/volume ratio of driving efficiency and lifetime maintenance-free. Precision planetary reducer is a use of speed reduction equipment, in order to better meet the needs of the industry, usually need to use custom parameters, power, specifications mode, planetary reducer in electronic equipment, automation equipment, infrastructure fields are used; Green Sky New Energy is committed to the development of small power miniature precision planetary reducer, the development of miniature precision planetary reducer parameters range in
