Abstract

The invention relates to a rotation device, in particular to a high-strength light rotation device required to bear the large load and to be low in weight. According to structural features, the strength performance and the weight index of a product, the shapes and sizes of an upper body and a lower body can be freely designed, a connecting piece connected with the rotation device is omitted, and the weight is effectively reduced. A hook-shaped structure of an engagement board is engaged with an annular groove structure of the lower body, a rotation guide effect is achieved, a gap generated inrotation is eliminated, the large load can be transmitted, and the problem that a common rotation device cannot bear the large radial load is effectively solved. A locking pin on the upper body is inserted in a locking hole of the lower body, so that the stability of a product structure is guaranteed, meanwhile the position of the locking hole can be determined according to actual requirements, and a locking function at different rotation angles can be achieved. The rotation device is simple in structure, convenient to install, free of limitation of the installation position and the size and high in reliability.

Description

technical field [0001] The invention relates to a rotating device, in particular to a high-strength and light-weight rotating device that needs to withstand high overload and requires light weight. Background technique [0002] The modern aviation industry has higher and higher expectations for the flight performance of aircraft, and pays more and more attention to the safety of crew members. The seat is an essential airborne equipment on the aircraft. Its main purpose is to provide a comfortable seating and use environment for the crew, and to protect the occupants from damage as a force transmission terminal in an aircraft crash environment. Therefore, the current aircraft overall unit has higher and higher requirements for the strength performance and weight index of the seat. [0003] Due to the cabin layout and use requirements, some seats on the aircraft need to have a rotary adjustment function. Domestic swivel seats basically use thrust ball bearings, steel ball sl...
