Planetary straight-tooth gearbox — 5:1 reduction, 160 mm frame
This is a planetary gearbox with straight teeth, 160 mm external diameter, and a reduction ratio of 5:1. The straight-tooth design offers higher efficiency at the cost of slightly more noise compared to helical, but the 94 % efficiency figure is competitive for this class — expect minimal thermal loss in the gear mesh. Continuous output torque is 450 N.m at 100 rpm and 30 °C; maximum output torque peaks at 720 N.m under the same conditions. The margin between continuous and max (450 vs 720 N.m) gives a 1.6× overload capacity — useful for intermittent peak loads like indexing or start-up transients.
Torsional rigidity, backlash, and service life
Torsional rigidity is 38 N.m/arcmin — this governs positioning accuracy under load; a higher number means less twist per unit torque. Maximum torsional backlash is 6 arc.min, which is typical for a precision planetary stage and acceptable for most positioning axes without a separate servo compensation. Rated service life is 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no re-greasing schedule, which simplifies maintenance in sealed or hard-to-access installations.
Load ratings: axial and radial forces
Maximum axial force Fa is 6000 N for a 30,000-hour life at 100 rpm and 30 °C, or 8000 N for a reduced 10,000-hour life. Maximum radial force Fr is 4200 N for 30,000 hours, or 6000 N for 10,000 hours, with the force applied at mid-distance from the output shaft. These limits define the overhung load the output bearing can sustain — exceeding them shortens life or causes premature bearing failure.
Environmental and mechanical specs
Shaft output seal is rated IP54 — splash-proof but not submersible; suitable for dry indoor environments or protected outdoor enclosures. Shaft material is C45 steel; housing is black anodized aluminium. Noise level at 1 m, no-load, is 70 dB — roughly the level of a vacuum cleaner, so acoustic enclosures may be needed in noise-sensitive areas.
