Product Introduction The flange output planetary gear reducer is a precision transmission device that combines a planetary gear system with a flange output structure. Its main components consist of a sun gear, planetary gears, and an internal ring gear, providing power transmission through single-stage or multi-stage meshing. The flange, serving as a crucial connecting component, features a circular design with built-in high-precision bearings, ensuring increased contact area and stable support. Compatible with power sources such as servo motors and stepper motors, this reducer is widely used in precision equipment, CNC machine tools, industrial robots, automated production lines, and aerospace technology.Flange Output with High-Precision Bearings The flange output design, equipped with high-precision bearings, provides increased contact area, stable mounting support, enhanced positioning accuracy, superior tensile rigidity, and exceptional torsional strength.Full Helical Gear Engagement for Enhanced Efficiency Full engagement of helical gears ensures excellent transmission efficiency: up to 97-98% for single-stage configurations and over 90% for multi-stage.High Precision and Low Backlash Precision grinding technology combined with a collet clamping mechanism minimizes backlash to ≤1 arc minute (1/60°), meeting strict servo system positioning accuracy requirements.Monolithic Construction for Increased Rigidity Integrated planetary carrier, internal ring gear, and sun gear eliminate secondary riveting points, ensuring unmatched structural integrity.High Load Capacity Multi-tooth engagement effectively distributes loads. With carburized/hardened gears and needle bearings, the reducer delivers output torque up to thousands of N·m and outstanding shock resistance.Noise Reduction and Stable Operation Patented noise-absorbing design and helical profile rolling engagement reduce operating noise to ≤65 dB, ensuring smooth, vibration-free operation.Durability and Maintenance-Free Operation Premium seals and permanent lubrication technology extend service life to over 20,000 hours, even under harsh conditions with high temperatures or particle contamination.Technical SpecificationsParameter TableSegment NumberRatioND047NDS064ND064NDS090ND090NDV110NDV140NDV200NDV255NDV285Rated Output TorqueN·mSingle4224545110130280560110022003600525555514516034061013002200330072048481251303005601200200029008———95100250550110017002850101540409510022046095014001900Double16224545110130280560110022003600202245451101302805601100200036002525606014516035061013002200330030————————3100352050501251403105601200120030004018505011012028056012001800—5018555514516034061013002000330060——481251203005601200180029007018—4812512030056011001800290080———95100—————90——40951002504609501500220010015—409510022046095014001900Parameter TableSegment NumberRatioND047NDS064ND064NDS090ND090NDV110NDV140NDV200NDV255NDV285Maximum Acceleration TorqueN·m1.21.8 times rated output torqueEmergency Stop TorqueN·m1.23 times rated output torqueRated Input Speedrpm14~105000500050004000400040003000300022002000216~1005000500050004000400040003000300030002200Maximum Input Speedrpm14~101000010000100008000800080006000600040003500216~1001000010000100008000800080006000600040003500Ultra-Precision Backlasharcmin14~10———≤1≤1≤1≤1≤1≤1≤1216~100—————≤3≤3≤3≤3≤3Precision Backlasharcmin14~10≤3≤3≤3≤3≤3≤3≤3≤3≤3≤3216~100≤5≤5≤5≤5≤5≤5≤5≤5≤5≤5Standard Backlasharcmin14~10≤5≤5≤5≤5≤5≤5≤5≤5≤5≤5216~100≤7≤7≤7≤7≤7≤7≤7≤7≤7≤7Orbit StiffnessN·m/arcmin1.24~1007101323319518352910301421Max.
