Joint assembly of the elements of the turntable of the test facility of the accident-resistant fuel system of the helicopter

摘要

The utility model relates to the field of helicopter engineering, namely to test facilities for testing the fuel system of a helicopter. To increase the reliability of the junction of the inner and outer frames of the turntable while creating conditions for a more even distribution of the load on the parts of the outer frame 12 and the inner frame 13 and to increase the accuracy during assembly, the junction of the elements of the turntable for testing the fuel system of the helicopter contains a bearing unit 7 with a spherical bearing 31 located in the housing of the bearing unit and mounted on the axis of the pin 16 connecting the elements of the turntable - the outer frame 12 and the inner frame 13 installed in it. On the outer frame 12, the housing 28 of the bearing unit is fixed, and it is equipped with a load distribution plate 8, connected to the housing of the bearing unit; pin 16 is made with an outer flange 19 and is provided with its own plate 14 formed by a flat part rigidly connected to the inner frame 13, and a cylindrical part 20 rigidly connected to the outer flange 19 of the pin 16. The inner frame 13 is also provided with a load distribution plate 15, through which the connection of the inner frame 13 with the plate 14 of the pin 1 is made. f-ly, 12 ill.
