Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the comprehensive carrier structure schematic diagram of the utility model Helicopter Main Reducer.
Refer to Fig. 1, the comprehensive bracket of the Helicopter Main Reducer that the utility model provides, comprise front baffle assembly 2 and rear frame assembly 6, wherein, described front baffle assembly 2 is connected by transition cross bar 4 with rear frame assembly 6, midship mounting platform 3 is provided with between described front baffle assembly 2 and rear frame assembly 6, described front baffle assembly 2 and rear frame assembly 6 are provided with many struts 5 around described midship mounting platform 3, one end of described strut 5 is free end, and the other end is flexibly connected with front baffle assembly 2 or rear frame assembly 6; Described front baffle assembly 2 is also provided with pull bar 1 and carries out translation for dilatory comprehensive bracket.
Fig. 2 is the front baffle unit construction schematic diagram of the comprehensive bracket of the utility model.
Please continue see Fig. 2, the comprehensive bracket of the Helicopter Main Reducer that the utility model provides, described front baffle assembly 2 comprises frame body 21, described frame body 21 is provided with strut bottom fitting 22, rod head 23, midship mounting platform joint 25, castor 26 and supporting leg 27, support bar 24 is provided with between described midship mounting platform 3 and frame body 21, described frame body 21 is provided with transition cross bar connecting panel 28, and described transition cross bar connecting panel 28 is connected with transition cross bar 4.The main composition spare part of rear frame assembly 6 is except setting up similar without other part fundamental sum front baffles 2 except rod head, and this is no longer going to repeat them.
Fig. 3 is the midship mounting platform structure schematic diagram of the comprehensive bracket of the utility model.
Please continue see Fig. 3, what the utility model provided rises the comprehensive bracket of owner's retarder, and described midship mounting platform 3 is primarily of straight AO bottom fitting, straight OI/AI bottom fitting and universal chassis composition; The back side of described midship mounting platform 3 is provided with reinforced rib 31.During due to straight OH main reduction gear use, chaff interference bottom main reduction gear need be avoided, therefore midship mounting platform 3 middle position leaves larger space.
