Abstract
The invention relates to a power transmission mechanism of a helicopter, which comprises a shaft, a telescopic shaft, a bearing, a bevel gear, a gear box, propellers and the like. The mechanism has the advantages of driving two coaxial propellers to rotate oppositely and converting vertical lifting force into a force in a horizontal advance direction. The mechanism is used for manufacturing double-propeller coaxial helicopters or span wing helicopters to improve the horizontal advance speed of the helicopters.
Description
The present invention relates to a kind of Power train of autogyro, various forms of autogyros are arranged on the market, but flying speed is generally slower, and the miniaturization difficulty.
The invention provides two coaxial backward rotation of propeller of a kind of assembling, in addition, the carrying sleeve of supporting propeller turning cylinder (or claiming gear case) wide-angle of fuselage work more than 90 ° relatively verts.So that power direction is forwarded to horizontal working direction in order to improve the horizontal speed of advance of autogyro.
The object of the present invention is achieved like this, and the present invention's double helix coaxial vertical-lifting mechanism is made up of two propeller, axle, quill drive, cone gear, gear case, bearing, the handle that verts (wheel) etc.Main shaft 2 is installed in the gear case 17 with quill drive 4 usefulness antifriction-bearing boxs 24,25,5,15, a cone gear 13 is housed on the main shaft 2, a cone gear 23 is housed on the quill drive 4, a cone gear 12 is housed on the dynamical axis 9, cone gear 12 is taken turns simultaneously altogether with cone gear 13,23, dynamical axis 9 links to each other with carrying sleeve 10 by two antifriction-bearing boxs 7, carrying sleeve 10 is installed on the gear case 17, entire mechanism is by plain bearing 11,20 on carrying sleeve 10 and axle 21, forms with frame (fuselage) to be rotatably connected.
Following in conjunction with the picture specification embodiments of the invention.
Power wheel 8 drives dynamical axiss 9, driven gear 12, and gear 12 driven gears 13,23 and main shaft 2, quill drive 4, two propeller 1,3 are done the rotation of positive and negative both direction.Bar handle 13 can make entire mechanism relative to rotating with the high spud angle of frame (fuselage) work above 90 °, can make aircraft finish vertical uplift like this, also can change to horizontal working direction to power direction, even lower.
Fig. 1 is a front view, and Fig. 2 is the birds-eye view of propeller, and Fig. 3 is propeller rotor cross section.
1,3 propeller among Fig. 1,2 imput shaft, 4 quill drives, 5,7,15,24,25 antifriction-bearing boxs, 6,22 supports (fuselage), 8 power wheels (gear, sprocket wheel, belt pulley), 9 dynamical axiss, 10 bearing carrying sleeves, 11,20 plain bearings, 12,13,23 cone gears, 14 bearing block circles, 16,18 case lids, 17 gears case, 19 turning handles, 21 tiliting axiss.Among Fig. 2,26 outer shrouds, 27 interior rings, 28 vanes (wing), 29 attaching partss (blade), 30 hubs.
Advantage of the present invention: the present invention's double-propeller coaxial vertical-lifting tilting and rotating mechanism can make two coaxial spiral shells Rotating plasma reverse rotation can change to the power of vertical lifting on the direction that level advances, and makes same with this mechanism The two slurry of axle (spademan) helicopter can improve the pace of the horizontal direction of helicopter.
Claims (3)
1, the present invention relates to a kind of Power train of autogyro, it is made up of axle, quill drive, bearing, cone gear, gear case, propeller etc.It is characterized in that driving on the axle of two propeller rotations and the quill drive and respectively adorn a cone gear, cone gear on the power input shaft is taken turns altogether with these two cone gears simultaneously, supports with the gear case that these cone gears and axle are installed and adopts bearing to be connected in the axial location of power input shaft with frame (fuselage).(connection bearing and power input shaft coaxial inner conductor)
