Device for detecting and adjusting gaps on two sides of rotating body in closed or semi-closed cavity

Abstract

The invention relates to a device for detecting and adjusting gaps on two sides of a rotating body in a closed or semi-closed cavity. The device comprises a connecting shaft sleeve, bearings, an adjusting seat, an adjusting locking nut, a protective cover, bearing limiting nuts and a connecting seat, wherein the connecting shaft sleeve is connected with the adjusting seat through the bearings, theconnecting shaft sleeve can freely rotate relative to the adjusting seat and is axially of an integral linkage structure, an inner hole of the connecting seats is in threaded transmission connectionwith an outer circle of the adjusting seat, and the adjusting seat is provided with a locking device and a sealing protection device; the connecting seat is arranged on the side cover of an outer cover of a rotating body, the connecting shaft sleeve is connected with a shaft head at one end of the rotating body, and the adjusting seat is rotated to drive the rotating body to move in the axial direction so as to achieve the effects of adjusting and detecting; and scale values are arranged on the connecting seat, and the accurate position of adjustment is displayed. The device has the beneficialeffects that during adjustment, the axial gaps are eliminated, the positioning of the rotating body can be accurately adjusted, and the actual side distance can be detected.

Description

technical field [0001] The invention relates to a shafting component, in particular to a device for detecting and adjusting the gap between two sides of a rotating body in a closed or semi-closed cavity. Background technique [0002] In the field of machinery, the use of a rotating body in a closed or semi-closed cavity is a very common structure, which requires precise axial positioning to ensure mechanical efficiency. If the gap between the two sides is too small, friction will occur, and if the gap is too large, it will The two sides are not sealed, resulting in leakage, and the gap on both sides is uneven, which will cause one side to rub and one side to leak, and the ideal mechanical efficiency cannot be achieved; in actual use, too many intermediate connectors make it difficult to distribute the precision of the size chain , the processing accuracy of each component is very high, and even cannot be guaranteed; and the rotating body is set in the box, and the actual ass...
