Abstract

The invention provides a large rotating body and rotating shaft connecting structure. The connecting structure comprises a radar cover (1) being a rotating body; the radar cover comprises a cover body, and radar cover upper and lower walls positioned at two ends of the cover body; a center sleeve (9) comprises a cylinder, and peripheral flanges vertically connected to the outer walls of two axial terminals of the cylinder; a rotating large shaft (7) comprises a step sleeve formed by axial butt joint of two cylinder bodies, a first peripheral flange vertically connected with the inner wall of one axial terminal of the step sleeve, and a second peripheral flange perpendicular to the outer wall of the transfer position of the step sleeve; the first peripheral flange is joined with an upper cover (3); a bearing (8) sleeves the lower half cylinder body; the cover body of the radar cover (1) and the upper half cylinder body of the rotating large shaft (7) are respectively sleeved between the outer wall of a center sleeve (9) and the inner wall; and the radar cover (1), the center sleeve (9) and the rotating large shaft (7) are detachably connected. The connecting structure is simple in structure, excellent in force transfer characteristics, convenient in maintenance and low in weight.

Description

technical field [0001] The invention belongs to the field of aviation technology, in particular to the field of aircraft structure design, in particular to a connection structure between a large rotating body and a rotating shaft. Background technique [0002] Rotating bodies with large size, large weight, and large inertia, such as radome, require radar 360° scanning on early warning aircraft, and the radome also rotates accordingly. How to connect the large rotating radome with the shaft so that the load of the rotating radome can be Transferred to the balance of the fuselage structure, it is a design and assembly problem. The quality of the connection design directly affects the safety of the aircraft, as well as the structural weight and antenna maintenance. [0003] The radome adopts the large shaft as the rotation drive, and the large shaft mainly bears the overload in the vertical direction. The connection between the large shaft and the radome not only ensures the st...
