Abstract

The invention discloses a servo planetary speed reducer with a good transmission effect. The servo planetary speed reducer comprises an input flange and an annular gear ring, the annular gear ring is connected with the input flange through screws, an input shaft is arranged inside the input flange through input shaft bearings, an output shaft is arranged inside the annular gear ring through annular gear ring bearings, the input shaft is connected with a primary sun gear, the primary sun gear is matched with primary planet gears, the primary planet gears are connected with a primary planet carrier, the primary planet carrier is connected with a secondary sun gear, the secondary sun gear is matched with secondary planet gears, the secondary planet gears are connected with a secondary planet carrier, the secondary planet carrier is connected with the output shaft, the primary planet gears and the secondary planet gears are respectively and rotatably arranged on roller pins through planet gear bearings, and the tooth directions of the primary planet gears and the secondary planet gears are arc. The servo planetary speed reducer has the advantages that the tooth directions of the planet gears are modified as an arc shape, a transmission clearance is small, a transmission effect is good, and transmission is more stable.

Description

technical field [0001] The invention relates to a reducer, in particular to a servo planetary reducer. Background technique [0002] In addition to the fact that the planetary gears in the planetary reducer can rotate around their own axis of rotation like fixed-axis gears, their rotation axis also rotates around the axis of other gears (sun gears) along with the planetary carrier and rotates around its own axis. It becomes the rotation, and the rotation around the axis of the other gear is called revolution, just like the planets in the solar system, hence the name. The tooth direction of the planetary gear in the existing planetary reducer is straight, the transmission gap is large, the transmission effect is not good, and the transmission is unstable. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a servo planetary reducer with good transmission effect. [0004] In order to solve the above-mentioned technica...
