Precision gears for the actuators that move robots and humanoids. We make the planetary gear sets, ring gears, ground spur and helical gears, pinions, and shafts that go inside robotic joints, from a first prototype through production.
Robot and humanoid joints live and die on their gearing. The actuator has to move with low backlash, low noise, and predictable accuracy, and hold that performance over millions of cycles in a tight, lightweight package.
INSCO makes the precision gears inside those actuators. Our core fit is the geared reduction stage: planetary gear sets, internal ring gears, and AGMA 15 ground spur and helical gears, along with the pinions and shafts that go with them. We can also build and test a complete gearbox sub-assembly, so you can source a working geared unit from one place.
Humanoid and advanced robotics is a young, fast-moving field. We support it the way it actually develops, from a single prototype and design iteration through to production volumes, backed by in-house engineering and reverse engineering when you are working from a sample.
The precision gear parts that go into robotic and humanoid actuators, all made and inspected in house.
Sun gears, planet gears, and the carrier gearing for planetary reduction stages, the most common geared path in robotic and humanoid actuators.
Internal ring gears for planetary and epicyclic drives, with tight-tolerance involute profiles cut and finished to match the planet set.
AGMA 15 precision ground spur and helical gears for low backlash, low transmission error, and quiet, repeatable motion at the joint.
Pinions, integral pinion shafts, and gear shafts, including teeth cut directly on the shaft for compact actuator packaging.
We can assemble the gearing with its supporting components and functionally test the unit, so you receive a working geared sub-assembly rather than loose parts.
100% analytical gear inspection of profile, lead, pitch, runout, and tooth thickness, with conformance documentation for your quality system.
