Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0022] like figure 2 As shown, the embodiment of the present invention relates to the transmission system technology of aircraft, which specifically provides a double-engine unmanned helicopter reduction transmission system. Compared with the prior art, the system has improved the power input method, which includes The reduction box 4 that main shaft 5 is connected, described reduction box 4 is provided with the output end large bevel gear 6 that is connected with described rotor main shaft 5, preferably, output end large bevel gear 6 is concentrically fixed with rotor main shaft 5, is installed in the reduction gear In the box 4, the large bevel gear 6 at the output end is used to drive the rotor main shaft 5 to rotate under the drive of power, and the rotor main shaft 5 is the power output end of...

Abstract

The invention discloses a double-engine unmanned helicopter deceleration transmission system and an unmanned helicopter. The transmission system comprises a deceleration box connected with a rotor main shaft, and an output end large bevel gear connected with the rotor main shaft is arranged in the deceleration box. Two input end small bevel gears engaged with the output end large bevel gear are connected to the output end large bevel gear, connected with engines correspondingly and symmetrically located on the two sides of rotor main shaft. The unmanned helicopter comprises the double-engine unmanned helicopter deceleration transmission system. The input end small bevel gears connected with the engines correspondingly are symmetrically arranged on the two sides of the rotor main shaft, and the acting force of the two input end small bevel gears on the output end large bevel gear are the same, so that the phenomenon of uneven stressing of the output end large bevel gear is avoided, abrasion of the output end large bevel gear is avoided, the service life is longer, and the safe and reliable effects are achieved; and the unmanned helicopter is safe and reliable, the service life of the unmanned helicopter is longer, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a double-engine unmanned helicopter deceleration transmission system and the unmanned helicopter. Background technique [0002] In order to improve the safety and reliability of unmanned helicopters, dual-engine configuration has become an important choice in the unmanned helicopter market, especially industrial-grade unmanned helicopters, which have long rotors, large sweeping areas, and equipment with high economic value. If the engine fails, the consequences will be unimaginable. Therefore, when one of the unmanned helicopters with dual engines fails, the other can continue to work, so that the unmanned helicopter has a certain degree of security. [0003] However, the existing dual-engine unmanned helicopter gear box deceleration design is the same side power input, such as figure 1 As shown, the power transmission is carried out in the way of one-way gear 1...
