Planetary Gearboxes for Industrial Robot Joints

APPLICATION Robot joints operate through changing lever arms and repeated reversals, so gearbox selection should use the joint motion envelope rather than one static arm position. Quick answer Planetary Gearboxes for Industrial Robot Joints should be evaluated from...

Planetary Gearboxes for CNC Feed Axes

APPLICATION CNC feed motion puts gearbox stiffness, backlash, acceleration and transmission geometry into the same accuracy chain. Quick answer Planetary Gearboxes for CNC Feed Axes should be evaluated from the real load and motion conditions, not from a single...

One-Stage vs Two-Stage Planetary Gearboxes

ENGINEERING COMPARISON Stage count changes available ratio, package length, inertia and the number of gear meshes. It should follow the ratio and motion requirements. Quick answer One-Stage vs Two-Stage Planetary Gearboxes should be evaluated from the real load and...

Selecting a Gearbox for High Input Speed Servo Motors

SELECTION GUIDE High motor speed changes bearing, lubrication, heat and noise conditions inside a reducer. A ratio that looks correct at output speed still has to be valid at the intended input speed. Quick answer Selecting a Gearbox for High Input Speed Servo Motors...
