Planetary gearbox for servo duty cycles
The GBX0600050852G is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 60 mm diameter, designed for servo-motor output stages where a 5:1 reduction is needed. Continuous output torque is 40 N.m at 100 rpm at 30 °C, with a peak capability of 64 N.m at the same speed and temperature — the margin covers acceleration transients and short overloads without exceeding the 30,000-hour service life target. Efficiency is listed at 96 %, which means about 4 % of the input power is lost as heat in the gear mesh and bearings — a figure that holds across the rated speed range and keeps the thermal load low enough for the lubricated-for-life grease charge.
Load ratings and mechanical limits
Maximum radial force Fr is 340 N at 100 rpm applied at mid-distance from the output shaft for a 30,000-hour life, or 500 N for a 10,000-hour life — the higher short-term rating suits infrequent positioning moves where the bearing L10 is not the limiting factor. Maximum axial force Fa is 450 N at 100 rpm for 30,000 hours, stepping to 600 N for 10,000 hours; the shaft material is C 45 steel, which handles these thrust loads without permanent deflection when the gearbox is mounted in any position. Torsional rigidity is 2.3 N.m/arcmin — this is the stiffness the output shaft presents to the load; a stiffer gearbox (lower compliance) reduces windup in position loops, but the 2.3 figure is typical for a straight-tooth planetary at this frame size.
