Problems solved by technology

Although it also adopts the form of power splitting, due to the structural strength and efficiency of the planetary gear transmission, its transmission is relatively small; at the same time, the planetary gear has both revolution and rotation, so the structure is complex, and the bearings supporting the planetary gear are easily damaged

Abstract

The invention discloses a coaxial type twin-rotor transmission device with a two-time power dividing function, and relates to a power transmission device capable of achieving two-time power dividing,wherein coaxial type twin rotors have the equal output power and rotation speed and the opposite rotation directions. The transmission device capable of achieving two-time power dividing is proposed by taking a coaxial type twin-rotor helicopter main speed reducer transmission system as an object in order to meet the requirements that an aviation product is small in size, low in weight and high inreliability. Two times of power dividing transmission are adopted, the transmission system achieves transmission by adopting simple fixed-axis wheel trains, and therefore the transmission device canbe easily achieved technically. The transmission device can be widely applied to the fields of medium and heavy helicopter transmission systems, ship transmission systems and the like.

Description

technical field [0001] The invention belongs to the technical field of helicopter reducer transmission, in particular to a coaxial double-rotor transmission device with two power splits. Background technique [0002] The typical configuration of the helicopter main reducer transmission system is "bevel gear reversing-parallel-planetary transmission output". From the input of the engine to the output of the main rotor, it is generally composed of 3 to 5 stages of gear transmission. In most cases, the planetary transmission is used as the last stage, and two-stage planetary transmission or compound planetary transmission is also used. For a multi-stage transmission system with planetary gear transmission, the allowable range of the transmission ratio of the planetary gear transmission is restricted by both structure and strength; at the same time, an excessive transmission ratio reduces the transmission efficiency of the planetary reducer. Therefore, in order to meet the powe...
