Problems solved by technology

[0003] In the cockpit of an aircraft, some equipment needs to use a rotating mechanism with adjustable damping. The traditional method of adding a hydraulic damper does not meet the requirements of the aircraft for small space and small mass, and the method of adjusting the thickness of the damping block is less reliable. Therefore, the compaction method can be used, but the existing structural size using the compaction method is relatively large, which cannot meet the small space size requirements of specific design models

Embodiment Construction

[0024] Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] like figure 1 and figure 2 Shown:

[0026] A damping adjustable rotating mechanism suitable for small spaces in this embodiment is composed of a load rotating member 1, an elastic damping ring 2, a damping telescopic rod 3, a damping turntable 4, a chuck 5, a fixing member 7 and a retaining ring 9.

[0027] The fixed part 7 has a protruding round platform, and the center of the round platform has an axial through hole; the axial through hole is in clearance fit with the cylindrical shaft of the load rotating part 1, and the end of the cylindrical shaft is realized by the retaining ring 9. Displacement constraints.

[0028] The outer surface of the circular platform protruding from the fixing part 7 has a circular segment; the damping telescopic rod ...

Abstract

The invention provides a damping adjustable rotating mechanism suitable for small space. The damping adjustable rotating mechanism suitable for small space is characterized that the rotating mechanismis composed of a load rotating piece, an elastic damping ring, a damping telescopic rod, a damping rotary disc, a chuck, a fixing part and a check ring, wherein the damping telescopic rod is arrangedon the fixing part, the damping rotating disc is arranged on the damping telescopic rod, the clamping disc is arranged on the fixing part through fixing screws, the load rotating piece is arranged onthe fixing piece, the elastic damping ring is arranged in a groove of the damping telescopic rod, a rubber ring is arranged in a groove of the damping rotary disc; the check ring is arranged in a groove of the load rotating piece. The damping rotating disc is rotated, and the damping telescopic rod is driven to carry out linear movement in the round-lack hole of the fixing part due to the matching action of the threaded, so that the elastic damping ring in the groove of the damping telescopic rod is close to the load rotating part, and the rotary damping is increased. The damping adjustable rotating mechanism is compact in structure and meets the requirement for installation of small space, the adjustment of rotation damping between the parts can be quickly realized only by the simple operation of the rotating the damping rotary disc.

Description

technical field [0001] The invention belongs to the field of mechanical design, in particular to a device suitable for the rotation between parts, and has the function of adjusting the damping during rotation. Background technique [0002] The rotation between parts is one of the most basic and common designs in mechanical design. Among them, there are many ways to adjust the damping size during rotation, and the common ones are the compression method, the method of adjusting the thickness of the damping block, the method of installing a hydraulic damper, etc. These methods of adjusting the damping size have their own characteristics and are suitable for various different occasions. [0003] In the cockpit of an aircraft, some equipment needs to use a rotating mechanism with adjustable damping. The traditional method of adding a hydraulic damper does not meet the requirements of the aircraft for small space and small mass, and the method of adjusting the thickness of the da...
