Problems solved by technology

But they all have a major flaw: when the "torque" is out of balance, it will also change the lift at balance, leading to the destruction of the original flight attitude when the course is changed, thus causing ...

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] As shown in Figure 1, the present invention includes a small bevel gear 10 driven by power, the small bevel gear 10 drives two large bevel gears 1, 11 at the same time, and two sun gears 2 are coaxially arranged with the two large bevel gears 1, 11 , 12, each sun gear 2, 12 simultaneously drives a group of planetary gears 3, 4, 13, 14 (with every group of two planetary gears as an example, it can also be three planetary gears), and the upper group of planetary gears 3 The central axis of , 4 is connected with a planetary gear carrier 5, and planetary gear 3, 4 is meshed with the internal tooth of a ring gear 6 at the same time; The wheels 13 , 14 mesh with the internal teeth of a ring gear 16 . The central shafts of the two output gears 7, 17 are connected to the two planetary gear carriers 5, 15 respectively. The two output gears 7, 17 mesh ...

Abstract

This invention is constant speed-differential speed, double shaft reverse output speed changing method and its device. A set of driving mechanism drive two groups of planet gear trains. The said planet gear trains drive two output shafts with same rotating speed and reverse direction. Another driving mechanism drives two control gears to rotate in same direction. The said control gears are assembled on the same control shaft and are respectively joggled to gear ring outer tooth of the said two sets of planet gear trains. Thus, the control gear can drive the gear ring of planet gear train to rotate in same speed. When the rotating direction of one gear ring is the same as the output direction of its corresponding planet gear train, the rotating direction of the other gear ring will be opposite to its corresponding planet gear train. This invention can be applied widely in the field of military affairs and civil aviation.

Description

technical field [0001] The invention relates to a speed change method and a speed change device, in particular to a constant speed-differential speed, two-axis reverse output speed change method and device in a mechanical epicyclic gear train deceleration and differential mechanism. Background technique [0002] In the helicopter family, there is a coaxial twin-screw helicopter, which is a helicopter with a pair of rotors on the same axis and rotating in opposite directions. Because it has no tail pipe and tail rotor, compared with conventional single-rotor helicopters, it has the advantages of small size, compact structure, low failure rate, and high hovering and medium-speed flight efficiency, so it is favored by various countries. However, because its control system technology is more complex than that of conventional single-blade helicopters, only the coaxial twin-blade helicopters designed by Russia's Kamov Design Bureau can be mass-produced and are widely used in milit...
