Rotary speed reducer and engineering machinery
The invention discloses a rotary speed reducer and engineering machinery. The rotary speed reducer comprises a bearing seat, a planetary gear train and a first bearing, wherein the bearing seat is fixedly arranged, a planet carrier of the planetary gear train is rotatably arranged in a shaft hole of the bearing seat, and the first bearing is supported between the planet carrier and the bearing seat. According to the rotary speed reducer provided by the invention, the first bearing is supported between the planet carrier and the bearing seat, and compared with the prior art, the position of the planet carrier moves towards the axial lower side, so that the axial size of the rotary speed reducer is reduced, and the structure is more compact.
本发明公开了一种回转减速机和工程机械。回转减速机包括轴承座、行星轮系和第一轴承，轴承座固定设置，行星轮系的行星架可转动地设置于轴承座的轴孔内，第一轴承支承于行星架与轴承座之间。本发明的回转减速机将第一轴承支承于行星架和轴承座之间，与相关技术相比，行星架的位置向轴向下侧移动，进而减小了回转减速机的轴向尺寸，结构更加紧凑。
