Embodiment Construction

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0036] The general idea of ​​the development of the power transmission device described in the present invention is that on the basis of the turboprop engine, in order to meet the power and speed requirements of the alternator, a new transmission chain for driving the alternator is added separately. The power of the alternator is increased, and the transmission of power can also be realized by the newly added transmission chain.

[0037] The power transmission device of the present invention adopts a non-orthogonal connection form among the gears and is inclined, so the power transmission device of the present invention can be called an oblique transmission device.

[0038] figure 2 is a schematic structural view of a preferred embodiment of the p...

Abstract

The invention provides a power transmission device, which is connected between an engine spindle and a generator, and comprises a transmission sleeve spindle and a transmission gear set of the generator, wherein the transmission sleeve spindle is sleeved on the engine spindle, and synchronously rotates with the engine spindle by a first connecting piece; and the transmission gear set of the generator comprises a plurality of mutually-connected transmission gears, the input end thereof is in transmission connection with the transmission sleeve spindle, and the output end thereof is in transmission connection with the generator. The power transmission device of the invention has the advantages that: because of adopting a structure that the transmission sleeve spindle is in transmission connection with the engine spindle, the power transmission device of the invention can directly extract power from the engine spindle so as to lead the generator to obtain larger driving power, and because of adopting the structure that the transmission sleeve spindle is sleeved on the engine spindle, the occupied space of a transmission mechanism can be saved effectively; and the transmission gear set of the generator is adopted to transmit power to the generator from the transmission sleeve spindle, and the power transmission capacity of the transmission gear set of the generator can be designed according to the power of the generator driven as required, therefore, the power transmission device can satisfy the requirements for driving a high-power generator.

Description

technical field [0001] The present invention relates to transmissions on aircraft, in particular to a power transfer device. Background technique [0002] At present, in order to meet the increasing demand for AC power on large and medium-sized aircraft and large helicopters, an auxiliary power unit (APU) is usually installed, but the use of this auxiliary power unit requires a special design in the aircraft storage compartment. A larger installation space, and the weight of the device is also larger, which is not conducive to the optimization of the structure and weight of the aircraft. [0003] Therefore, in order to reduce the occupancy of the limited space on the aircraft and reduce the weight of the aircraft, the prior art usually arranges a transmission mechanism on the main shaft of the aircraft engine, such as figure 1 As shown, a middle transmission assembly 20 is set on the engine main shaft, that is, the elastic shaft 1, through which a part of the power output b...
