Abstract

The invention discloses a self-centering mechanism for large-diameter centering rotary equipment. The rotary equipment comprises a fixed part and a rotating part, wherein the self-centering mechanism is arranged between the fixed part and the rotating part; one of the fixed part and the rotating part is cylindrical while the other one is provided with a corresponding inner cavity; the cylinder is located in the inner cavity; a roller path is arranged on the outer circumferential surface of the cylinder; the self-centering mechanism comprises at least two groups of rolling units, wherein at least one group of rolling units are adjusting units used for adjusting the position of the rotating part; at most one group of rolling units are positioning units, and the positioning units are arranged at the positioning reference of the fixed part; and the rotating part concentrically rotates relative to the fixed part through the adjusting units. According to the self-centering mechanism for the large-diameter centering rotary equipment, an aligning tool does not need to be additionally arranged, automatic centering is achieved, the assembly precision of a rolling pair is high, stress is balanced, and the self-centering mechanism is suitable for an inner centering outer rotation mechanism or an outer centering inner rotation mechanism.

Description

technical field

[0001] The invention relates to the structural technical field of large-scale construction machinery rotating equipment, in particular to a self-centering mechanism for large-diameter centering and rotating equipment. Background technique

[0002] In construction machinery, based on comprehensive factors such as cost, environmental conditions, and ease of implementation, a guide wheel raceway structure is used as a rotary centering and radial support mechanism for large-diameter inner rotary parts. In this structure, the center of the inner cavity of the frame is the center of rotation of the central column. There are several support wheels installed on the frame, usually 4, 6, 8... etc. even numbers according to the diameter of the center column, generally distributed evenly and symmetrically with the center column, these support wheels are constrained by the raceway pre-positioned on the center column , so as to realize the positioning of the center of the...
