72JX850K 72mm 15-85N.m Planetary Gearbox

72JX850K 72mm 15-85N.m Planetary Gearbox

The 72JX850K features a metal planetary gear construction with an outer diameter of 72 mm for both compact and high torque output. The allowable torque ranges from 15N.m to 85N.m, and supports dual voltages of 12V/24V to adapt to different energy efficiency scenarios.
The transmission ratio of the single-stage planetary gearbox is generally between 3-10, and when the multistage planetary gearbox is used in series, the transmission ratio can reach dozens or even hundreds, which can meet the requirements of different equipment for the transmission ratio. Compared to conventional parallel-shaft gearboxes, planetary gearboxes can be 30% to 50% smaller in volume and lighter in weight than conventional parallel-shaft gearboxes with the same transmission ratio and load capacity, making them easy to install and deploy in space-constrained equipment.
