Planetary gearbox, 40 mm, 15:1 reduction — obsolete, sourced per RFQ
The Schneider Electric GBX0400151001F is a planetary gearbox with a 40 mm external diameter and a 15:1 reduction ratio, delivering 18 N.m continuous output torque at 100 rpm and 30 °C ambient. Rated for 30000 hours service life at those conditions, with maximum intermittent torque of 29 N.m for short-duration peaks.
The 18 N.m continuous torque at 100 rpm defines the steady-state load the gearbox can transmit without exceeding its thermal or mechanical limits; the 29 N.m maximum rating covers acceleration peaks, shock loads, or stall conditions within the duty cycle. Maximum torsional backlash of 28 arc.min means the output shaft can rotate up to 28 arc-minutes before the input engages — significant for positioning or indexing applications where lost motion must be budgeted into the servo loop or cam profile. Ambient operating range -25 to 90 °C covers most indoor industrial environments but not extended sub-zero or high-heat zones; the IP54 shaft output seal protects against dust ingress and light splashing but is not rated for washdown or submersion.
Efficiency, noise, and bearing loads — integration constraints
94 % efficiency at rated load means 6 % of input power is lost as heat inside the gearbox — relevant for thermal management in enclosed spaces or when sizing upstream motor power. Noise level 55 dB at 1 m, no-load, is moderate — acceptable for most machine-tool or conveyor applications but may need acoustic enclosure in noise-sensitive installations.
Construction and maintenance — lubricated for life, sealed unit
Straight-tooth planetary design with black anodized aluminium housing and C45 steel shaft. Lubricated for life — no grease-change interval, no maintenance ports; the gearbox is a sealed, replace-as-assembly component. Shaft output IP54 means the seal at the output shaft is protected against dust ingress and splashing water, but the gearbox body itself is not rated for washdown environments — mounting orientation and drip protection should be considered in the enclosure design.
