Slewing bearing assembly and engineering machinery
The invention provides a slewing bearing assembly and engineering machinery, and relates to the technical field of slewing devices. The slewing bearing assembly comprises a first rotary body, a second rotary body, a transmission mechanism and an auxiliary mechanism, wherein the transmission mechanism and the auxiliary mechanism are both mounted between the first rotary body and the second rotary body; the auxiliary mechanism comprises a moving part and an annular guide rail, the guide rail is arranged on the outer side of the transmission mechanism in the circumferential direction of the transmission mechanism, and the moving part is installed in the guide rail; when the first rotary body and the second rotary body rotate relatively, the moving part moves in the circumferential direction of the guide rail relative to the guide rail. When the first rotary body and the second rotary body incline relatively, the guide rail and the moving part abut against each other in the direction opposite to the inclination trend of the moving part so that the moving part can be limited in the guide rail. The technical problem that when a slewing bearing assembly in the prior art is applied to engineering machinery, an upper chassis in the slewing bearing assembly is prone to warping forwards or backwards, and consequently a transmission mechanism is prone to being damaged due to long-term eccentric stress is solved.
本发明提供一种回转支承组件和工程机械，涉及回转装置技术领域。该回转支承组件包括第一回转体、第二回转体、传动机构和辅助机构，传动机构和辅助机构均安装在第一回转体和第二回转体之间；辅助机构包括移动件和环形的导轨，导轨沿传动机构的周向设置在传动机构的外侧，移动件安装在导轨中；当第一回转体和第二回转体相对回转时，移动件相对于导轨沿导轨的周向移动；当第一回转体和第二回转体相对倾斜时，沿与移动件的倾斜趋势相反的方向，导轨和移动件相互抵接，以将移动件限定在导轨中。本发明缓解了现有技术中回转支承组件应用于工程机械时，回转支承组件中的上底盘易于前翘或后翘，导致传动机构易长期偏心受力而损坏的技术问题。
