Planetary gearbox, 15:1 reduction, 230 N.m continuous
The GBX1200150701F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 120 mm housing diameter and a 15:1 reduction ratio. It delivers 230 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 368 N.m under the same conditions. Rated efficiency is 94 %, with a maximum torsional backlash of 12 arcmin and torsional rigidity of 13 N.m/arcmin — the stiffness figure governs positioning accuracy under load in a servo axis.
Load ratings and service life at 100 rpm
The gearbox is rated for 30000 hours service life at 100 rpm and 30 °C, with the output shaft protected to IP54. Maximum axial force (Fa) is 2100 N for the 30000-hour target, or 2800 N for a 10000-hour duty cycle; maximum radial force (Fr) is 1500 N for 30000 hours, or 2000 N for 10000 hours — both measured at mid-span on the output shaft. The housing is black anodized aluminium, the shaft is C 45 steel, and the unit is lubricated for life — no maintenance oil changes are needed over the service interval. Noise level is 65 dB at 1 m under no-load conditions; ambient operating range is -25 to 90 °C.
