The invention relates to a supporting structure of a rotary speed reducer, a rotary mechanism, a crane and a method. The supporting structure comprises two positioning rings which are fixed through asupport and are distributed up and down, the central axes of the two positioning rings coincide, adjusting rings are arranged on the inner rings of the positioning rings in a sleeving mode, the adjusting rings are supported through the positioning rings, and the adjusting rings can rotate along the positioning rings and are fixed; and mounting holes are formed in the adjusting rings, the mountingholes and the outer circle contours of the adjusting rings are eccentrically arranged, the mounting holes are used for allowing the speed reducer to penetrate through, the mounting holes and an outputshaft of the speed reducer are coaxially arranged, and the rotating of the adjusting rings can change the gap and the angle of corresponding teeth between a gear at the output shaft of the speed reducer and an external gear ring.

    本公开涉及一种回转减速机的支撑结构、回转机构、起重机及方法,包括通过支架固定且上下分布的两个定位环,两个定位环的中心轴线重合,定位环的内圈套设有调节环,调节环通过定位环支撑,调节环能够沿定位环转动并固定;调节环中设有安装孔,安装孔与调节环的外圆轮廓偏心设置,安装孔用于穿过减速机,安装孔与减速机的输出轴同轴设置,调节环的转动能够改变减速机输出轴处齿轮与外部齿圈之间对应齿的间隙与角度。
