Abstract

The invention discloses an accessory transmission structure. The accessory transmission structure comprises a speed regulator, an oil mist separator, two starting motors, a power input transmission mechanism, a speed regulator transmission mechanism, an oil mist separator transmission mechanism and a starting motor transmission mechanism. The power input transmission mechanism is arranged along a straight line, and the power input end of the power input transmission mechanism is connected with a middle transmission mechanism in the case shell. The speed regulator transmission mechanism is perpendicular to and connected with the power input transmission mechanism. The oil mist separator transmission mechanism and the starting motor transmission mechanism are sequentially arranged in the axial direction of the speed regulator transmission mechanism, and the oil mist separator transmission mechanism is perpendicularly connected with the speed regulator transmission mechanism. The starting motor transmission mechanism is symmetrically arranged about the axis of the speed regulator transmission mechanism, and the two power output ends of the starting motor transmission mechanism are connected with the starting motors on the corresponding sides in the axial direction. By designing the accessory transmission structure, normal work of the interior of the case and an accessory transmission system can be achieved, and meanwhile the accessory can be compactly installed on the case shell.

Description

technical field [0001] The invention relates to the field of aero-engine transmission systems, in particular to an accessory transmission structure. Background technique [0002] When designing a certain type of aeroengine transmission system, multiple accessories are required to be installed on the casing, and each accessory needs to be designed for transmission. In order to reduce the outer dimensions of the case casing, thereby reducing the weight of the casing and meeting the transmission requirements, it is necessary to set the transmission device to meet the requirements of the transmission system and achieve a compact structure. [0003] The design and layout of the existing transmission device are unreasonable, which cannot well meet the transmission requirements, and lead to heavy weight of the casing, which does not meet the requirements of the transmission system. Contents of the invention [0004] The invention provides an accessory transmission structure to s...
