15:1 planetary reducer — what the duty ratings actually mean
The GBX1200150704F is a 120 mm diameter planetary gearbox with straight teeth, delivering a 15:1 reduction ratio. The continuous output torque is 230 N.m at 100 rpm and 30 °C — this is the figure to size against your load's RMS torque, not the 368 N.m maximum peak rating. Service life is rated at 30,000 hours at that continuous torque and speed. The gearbox is lubricated for life, so no oil-change interval to budget for in the maintenance schedule.
Backlash, forces, and mounting constraints
Maximum torsional backlash is 12 arc.min — fine for general positioning and conveyor indexing, but a lower-backlash unit (helical or precision planetary) would be needed for servo-axis reversal accuracy under 5 arc.min. Maximum radial force Fr is 1500 N at 100 rpm for the 30,000-hour life target, applied at mid-distance from the output shaft. Axial force Fa caps at 2100 N under the same duty cycle. Both can be pushed 33% higher if you accept a 10,000-hour service life instead. The shaft output seal carries IP54 protection — fine for dry indoor environments but not rated for washdown. Ambient operating range is -25 to 90 °C.
Efficiency and noise — what to expect on the line
Listed efficiency is 94% — typical for a single-stage planetary with straight teeth. The remaining 6% is heat; at 230 N.m and 100 rpm that's about 145 W thermal loss to dissipate through the black anodised aluminium housing. Noise level is 65 dB at 1 m, no-load. Straight-cut gears are inherently noisier than helical; expect a whine under load that may be audible above plant background noise. If the gearbox sits near a work station, a helical unit would run quieter.
