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
The present invention relates to a kind of speed reducer, relate in particular to a kind of servo planetary speed reducer.
Background technique
Planetary pinion in planetary speed reducer is except can be as fixed axis gear rotating round oneself rotatingshaft, their rotatingshaft is also along with the axis of planet carrier around other gear (sun gear) rotates, rotation around own axis becomes rotation, rotation around other Gear axis is called revolution, just as the planet in the solar system, hence obtain one's name.In existing planetary speed reducer, the teeth directional of planet wheel is straight shape, and drive gap is large, and the transmission effect is bad, and transmission is unstable.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of transmission effective servo planetary speed reducer.
in order to solve the problems of the technologies described above, the technical solution used in the present invention is: servo planetary speed reducer, comprise: input flange, the ring gear that is connected with input flange by screw, be provided with input shaft by bearing of input shaft in input flange, be arranged on output shaft by the ring gear bearing in ring gear, described input shaft is connected with the one-level sun gear, one-level sun gear and one-level planet wheel cooperatively interact, the one-level planet wheel is connected with primary planet carrier, primary planet carrier is connected with secondary solar gear, secondary solar gear and secondary planet wheel cooperatively interact, the secondary planet wheel is connected with the secondary planet frame, the secondary planet frame is connected with described output shaft, described one-level planet wheel and secondary planet wheel rotate by planet wheel bearing respectively and are arranged on needle roller, the teeth directional of described one-level planet wheel and secondary planet wheel is arc.
Advantage of the present invention is: above-mentioned servo planetary speed reducer, and the teeth directional of planet wheel is repaiied to be arc, drive gap is little, and transmission is effective, more stable transmission.
