Problems solved by technology

Because the carriage is only supported on one side, the alignment of the gears can be unstable during carriage rotation, creating noise, which is problematic
[0003] In addition, the sun gear is located on the other side of the carrier in the radial direction, making it difficult to assemble the sun gear and obtain a bearing surface for the bearings
Therefore, it is difficult to use bearings or bushings to support the bracket

Abstract

The present disclosure relates to a planetary gear device including: a carrier plate having a perforated central portion; a plurality of pinions rotatably mounted on the carrier plate; a sun gear inserted into the bracket plate and engaged with the pinion gear; a support ring mounted around an outer surface of the sun gear; and a rotation support mounted on the bracket plate and supporting the support ring such that the support ring is rotatable. The planetary gear device according to the present disclosure may support a carrier plate and include a support ring mounted on an outer surface of a sun gear, thereby reducing noise and improving durability.

Description

technical field [0001] Exemplary embodiments of the present disclosure relate to a planetary gear device, and more particularly, to a planetary gear device capable of supporting a carrier plate. Background technique [0002] In prior art planetary gear units, the radial support structure of the carrier supports the carrier on only one side using bearings. Because the carriage is only supported on one side, the alignment of the gears can be unstable during carriage rotation, creating noise, which is problematic. [0003] In addition, the sun gear is located on the other side of the carrier in the radial direction, making it difficult to assemble the sun gear and obtain a bearing surface for the bearing. Therefore, it is difficult to support the bracket using bearings or bushings. Therefore, improvements are required to solve this problem. [0004] The background art of the present disclosure is disclosed in Korean Patent No. 10-1896371 (titled "Planetary Gear Device (PLANE...
