Abstract

The invention discloses a torsion-transmission helicopter reducer. The torsion-transmission helicopter reducer comprises a reversing gear pair, wherein the reversing gear pair comprises two driving gears and two driven gears which are respectively engaged with different driving gears, the two driving gears are connected with each other through a power elastic shaft, and one driving gear is connected with a power input shaft. A cylindrical gear pair comprises a plurality of cylindrical driving small gears and a plurality of cylindrical drive large gears, and the cylindrical driving small gears are respectively and coaxially connected with the corresponding driven gears. A herringbone gear pair comprises a plurality of driving small herringbone gears and a parallel herringbone gear, the plurality of driving small herringbone gears are simultaneously engaged with the parallel herringbone gear, the transmission ratio is greater than 1, and the driving small herringbone gears are respectively and coaxially arranged with the corresponding cylindrical driven large gears. A rotary wing shaft assembly is coaxially arranged with the parallel herringbone gear. The torsion-transmission helicopter reducer adopts the multichannel power transmission and is simple in structure, less in component quantity, high in reliability, relatively small in size, low in gear linear speed and light in weight.

Description

technical field [0001] The invention relates to the field of helicopter reducers, in particular, to a torque split transmission helicopter reducer. Background technique [0002] In the traditional helicopter reducer, the power of the engine is transmitted in a single way from the beginning to the process of paralleling, and is decelerated step by step; after paralleling, it is output to the rotor shaft by a single-stage or two-stage planetary deceleration. This traditional configuration is more suitable for the main reducer of large and below tonnage helicopters. When the traditional helicopter reducer is applied to the main reducer of heavy-duty helicopters, the single-way transmission power is too large, resulting in a large volume of the reducer, heavy weight, high gear linear speed, and large vibration and noise. Contents of the invention [0003] The purpose of the present invention is to provide a torque split transmission helicopter reducer to solve the technical p...
