Technical Field

[0001] The invention relates to the technical field of friction clutches and shock absorbers, and in particular to a compact space friction clutch shock absorber assembly and an installation method. Background Art

[0002] The external azimuth and pitch axis components of large optoelectronic pods need to have strong torque reserves to resist external disturbances; therefore, in order to meet the motion requirements, high-power motor solutions are usually used, but this often exceeds the maximum current limit that the aircraft can provide. Therefore, in many cases, solutions with reducers are selected.

[0003] In order to ensure that the coordinate system of the optoelectronic equipment is consistent with the aircraft coordinate system, the external azimuth and pitch axis systems of the optoelectronic equipment are not equipped with shock absorbers; when faced with large shocks and vibrations, excessive loads will be directly transmitted to the relevant gears of the reducer, causing damage to the reducer.

[0004] In order to avoid transferring excessive load directly to the optoelectronic pod in the event of overload, a common clutch solution can be introduced. However, relying solely on the clutch is not enough, so a set of shock absorber structures is added on this basis to effectively protect the reducer and optoelectronic equipment, thereby extending their service life and improving the reliability of the system.

At the same time, the assembly has a compact structure and occupies a small space, which meets the installation and design requirements of the optoelectronic equipment.

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, the elastic device is a disc spring 8, which is arranged on the adjustment pin 7 between the clutch inner ring 9 and the clutch outer ring 10; the compact space friction clutch shock absorber assembly also includes an upper gasket 6, which is arranged on the disc spring 8 at one end close to the clutch inner ring 9; the compact space friction clutch shock absorber assembly also includes a lower gasket 5, which is arranged on the disc spring 8 at one end close to the clutch outer ring 10; the arrangement of the disc spring 8 effectively buffers the impact of external forces on the shock absorber 11 and the optoelectronic device, and at the same time, an upper gasket 6 and a lower gasket 5 are arranged at both ends of the disc spring 8 to realize the limited installation of the disc spring 8, and a thread is arranged on the adjustment pin 7, which passes through the center holes of the clutch inner ring 9, the lower gasket 5, the upper gasket 6 and the disc spring 8, and is finally connected to the clutch outer ring 10.

[0029] like Figure 1 and Figure 2As shown, in this embodiment, the outer ring of the bearing 3 is connected to the bearing cover 2 and the clutch outer ring 10, wherein the outer ring of the bearing 3 is connected to the clutch outer ring 10 through an axial hole, and the inner ring of the bearing 3 is connected to the clutch inner ring 9 through an axial hole. Since the clutch outer ring 10 is connected to the reducer flange through the first mounting flange, the movement of the clutch outer ring 10 and the reducer is synchronized. Through the setting of the bearing 3, relative movement is generated between the clutch outer ring 10 and the clutch inner ring 9. The overload vibration transmitted from the outside is reduced by the shock absorber 11 to protect the optoelectronic pod and optoelectronic equipment. The bearing cover 2 and the clutch outer ring 10 also limit the axial displacement of the bearing 3. The bearing cover 2 presses the bearing 3 to prevent the bearing 3 from axial movement.

[0032] like Figure 1 and Figure 2 As shown, the present invention also includes a method for installing a compact space friction clutch shock absorber assembly, which is implemented based on any of the compact space friction clutch shock absorber assemblies described above.
