Abstract
The invention discloses a servo planet gear speed reducer. The servo planet gear speed reducer comprises an input flange, a rear flange connected with the input flange through a first screw, and an inner gear ring connected with the rear flange through a second screw. An input shaft is arranged in the rear flange through an input shaft bearing. An output shaft is arranged in the inner gear ring through an output shaft bearing. One end of the input shaft penetrates the input flange to be connected with a driving device; and the other end of the input shaft stretches into the inner gear ring to be connected with a gun gear. The sun gear and a plurality of planet gears are engaged with each other. The planet gears and the inner gear ring are engaged with each other. The planet gears are rotationally arranged on planet gear pin shafts through crowded needle roller bearings. One end of each planet gear pin shaft stretches out of the corresponding planet gear to be connected with a rear planet carrier. The rear planet carriers are rotationally arranged in the rear flange and the inner gear ring through planet carrier bearings.
Description
Technical field
