High Precision Planetary Gearbox

High Precision , also known as Servo Motor Planetary Gearbox, is a precision transmission device designed specifically for servo motor systems. This gearbox adopts a structure, where multiple planetary gears rotate around a central sun gear and are embedded in an inner ring gear, achieving torque conversion and speed reduction between the input and output shafts in this way.

② Precision planetary carrier

The planetary arm frame and output shaft adopt an integrated structural design, with large spans of front and rear bearings distributed inside the box, forming a stable integrated structure. Ensure high torsional rigidity and accuracy. Adjust the axial clearance through the adjustment screw on the planetary carrier

③ Inner gear ring

The gear ring and output end housing adopt an integrated design, using high-quality color steel and hot forging to achieve high material density. The integrated design ensures that all geometric dimensions can be processed at once, and has higher accuracy and strength compared to other embedded, clamped and other structures.

④ Input shaft

The input shaft and locking device adopt an integrated design with symmetrical distribution of double bolts, achieving dynamic balance. By using double bolt strong locking, the motor shaft transmission is effectively prevented from slipping, achieving high-precision zero backlash power transmission.
