Ring gear structure and planetary gear transmission device

Abstract

The embodiment of the invention provides a ring gear structure and a planetary gear transmission device, and relates to the technical field of mechanical equipment. The ring gear structure provided bythe embodiment of the invention includes a first-class ring gear and a second-class ring gear, the first-class ring gear is used for meshing with a first-class planetary gear, and the second-class gear ring is used for meshing with a second-class planetary gear. The first stage ring gear and the second stage ring gear are actively connected with each other, and a gap is formed between the first-class ring gear and the second-class ring gear. Therefore, in the process of use, the second-class ring gear can float relative to the first-class ring gear, correspondingly, the first-class ring gearcan float relative to the second-class ring gear, that is, the first stage ring gear and the second stage ring gear can be relatively independent floating by separately arranging the first stage ringgear and the second stage ring gear. At the same time, floating effect is achieved, and uniform load effect is good. Noise is reduced, eccentric wear phenomenon is reduced, and then use effect is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a ring gear structure and a planetary gear transmission. Background technique [0002] Planetary gear transmission is a commonly used gear transmission system at present, which includes sun gear, planetary gear, planet carrier and ring gear. Two sun gears are arranged at intervals along the circumferential direction of the sun gear, and the planet carrier is rotationally connected with a plurality of planet gears. Planetary gear transmission has been widely used due to its characteristics of "high load and large transmission ratio", such as planetary gear transmissions such as reducers. [0003] The reducer often uses two-stage or more planetary gear transmissions, so its ring gear includes at least one-stage ring gear and two-stage ring gear. Among the existing two-stage and more than two-stage planetary gear transmissions, the first stage The ring gear and the se...
