Cantilever crane rotating mechanism, cantilever crane and engineering machinery
The invention relates to the field of arm rests, and discloses an arm rest rotating mechanism, an arm rest and an engineering machine.The arm rest rotating mechanism comprises an outer ring (8), an inner ring (17), a guiding part and a driving part, the outer ring (8) and the inner ring (17) are arranged around the central axis in a sleeved mode, and one of the outer ring (8) and the inner ring (17) is provided with a wave-shaped guide rail extending in the circumferential direction; the driving piece can drive the guide part to move in the axial direction relative to the other one of the outer ring (8) and the inner ring (17), so that the guide part acts on the guide rail in the axial direction, the guide rail is driven to slide in the circumferential direction relative to the guide part, and the inner ring (17) and the outer ring (8) are driven to rotate relatively around the central axis. According to the technical scheme, the guiding part is driven by the driving piece to move axially, relative rotation of the inner ring can be achieved, the structure is relatively simple, the number of parts is relatively small, the driving structure is suitable for the arm sections of the arm support, the overall weight is smaller, and light weight is achieved.
本发明涉及臂架领域，公开了一种臂架旋转机构、臂架及工程机械，所述臂架旋转机构包括围绕中心轴线彼此套设的外环(8)和内环(17)、导向部、驱动件，所述外环(8)和所述内环(17)的一者上设置有周向延伸的波形的导轨，驱动件能够驱动所述导向部相对于所述外环(8)和所述内环(17)的另一者的沿轴向方向移动，使得所述导向部沿轴向作用于所述导轨，从而驱动所述导轨相对于所述导向部周向滑动，以驱动所述内环(17)和所述外环(8)围绕中心轴线相对旋转。通过上述技术方案，通过驱动件驱动导向部轴向移动，可以实现内环的相对转动，其结构相对简单，部件相对较少，适用于臂架的臂节之间的驱动结构，整体重量更小，实现轻量化。
