Planetary roller gear
WebDec 1, 2024 · Abstract The kinematics of a planetary roller–screw gear, which converts the rotational motion of a drive nut connected to an electric motor into the translational motion of a screw, is calculated. The nut is threaded with rollers arranged concentrically around the screw via two separators connected to the rollers by pins. A formula is derived to … WebApr 17, 2015 · Answer: You get a planetary roller screw. Replacing the recirculating balls of a ball screw with grooved rollers results in a precision drive mechanism with extremely high load capacity, acceleration, and speed capabilities, all in a small footprint.
