Problems solved by technology

[0002] In the NGW planetary transmission, due to the axial fixation between the sun gears, friction will inevitably occur due to relative motion, which will cause the axial gap between the sun gears to increase, and the reducer will heat up, thus affecting the planetary reducer. life

Abstract

The invention provides a planetary transmission structure. The planetary transmission structure comprises a single-stage bevel gear box, a first sun gear, a first planetary carrier, a first inner gear, a second sun gear, a second planetary carrier and a second inner gear, wherein the single-stage bevel gear box comprises an output shaft; the output shaft, the first sun gear and the second sun gear are positioned on the same axis; the front end of the first sun gear is mounted on the output shaft; a first bearing is mounted between the rear end of the first sun gear and the front end of the second sun gear; an outer ring of the first bearing is fixed to the rear end surface of the first sun gear, and an inner ring of the first bearing is fixed to the front end surface of the second sun gear; the first planetary carrier is fixedly connected to the front end of the second sun gear; a second bearing is mounted between the rear end of the second sun gear and the second planetary carrier. According to the technical scheme, the planetary transmission structure has the advantages that two sun gears are correspondingly independently rotated around the corresponding bearings, so that direct contact can be avoided, and the friction can be greatly reduced.
