High Precision Low Backlash Planetary Gearbox Square Flange Reduction for Servo Motor
Product Description
High Precision Square Flange Planetary Reducer for Servo Motors
High precision low backlash servo planetary gearbox (square flange) is engineered for servo motors and related equipment requiring speed reduction or torque amplification. Boasting minimal backlash (≤3 arcminutes) for superior transmission accuracy, it pairs seamlessly with servo motors and fits servo-driven scenarios like automated production lines, robot joints, and precision machine tools, with its square flange design streamlining installation. Besides standard configuration, this planetary reducer series supports non‑standard mechanical customization, including output‑shaft resizing, mounting hole reworking and input‑shaft keyway addition. We can deliver revised 2D drawings and STEP 3D documents for custom variants, refer to customization case below for real‑world project reference.
Key Features
Low Noise: Using involute gear transmission, alloy steel with carbonize & quencher heat treatment, precision level of gear grinding could reach ISO class 5. The profile and axial modification could enhance the bearing capacity to achieve smooth, quiet operation of the reducer.
High Precision: Backlash is 3 arcmin or less for accurate positioning.
High Rigidity & High Torque: The output shaft adopts large size, large span double support bearing design, which improves the rigidity and torque of the reducer.
High Efficiency: 1-stage efficiency up to 95% or more, 2-stage efficiency up to 92% or more.
Maintenance-Free: Low grease wear, supports lifetime lubrication.
Excellent Sealing Performance: Adopts high-viscosity lubricating grease that is not easy to separate. IP65 protection class ensures no grease leakage.
Wide Applicability: Compatible with all types of servo motors. Customization for special combinations is supported, and installation is simple.
