Description
Planetary gearbox Li Ming FA120, i = 20, for servo motor Delta ECMA-…1310 (input Ø22 mm, flange 7MP120A-110-A).
- The FA series of precision planetary gearboxes from Li Ming for servo motors: sizes 50–180, 1 stage (i = 3–10) and 2 stages (i = 15–100), input 100 W – 30 kW.
- The gears are helical (twice the engagement of straight gears), made of Ni-Cr-Mo steel SNCM220, hardened to 57–60 HRC and ground to DIN 6 class.
- The satellite guide is integrated with the output shaft, and the satellites are mounted on needle bearings without a separator - for higher torsional stiffness.
- The motor is mounted with a dynamically balanced collet, ensuring no backlash in the connection at high speeds.
- FA120 at i = 20: nominal output torque 255 Nm, emergency 3 × T2N, acceleration 1.8 × T2N; backlash ≤ 12 arcmin; efficiency ≥ 94 %.
- Allowable forces on the output shaft: radial 5220 N, axial 2600 N; torsional stiffness 23 Nm/arcmin; service life > 30,000 h at S5 (> 15,000 h at S1).
- Output shaft Ø32 h6; input openings for FA120 are Ø 22, 24, 28, 32 mm, centering diameter for the motor (C5) — 95, 110, 130 mm.
