Abstract

The invention discloses an accessory transmission structure, comprising: a governor, an oil mist separator, two starter motors, a power input transmission mechanism, a governor transmission mechanism, an oil mist separator transmission mechanism, and a starter motor transmission mechanism. The power input transmission mechanism is laid out along a straight line, and its power input end is connected to the middle transmission mechanism in the case housing. The transmission mechanism of the speed governor is arranged and connected vertically to the power input transmission mechanism. The transmission mechanism of the oil mist separator and the transmission mechanism of the starter motor are sequentially arranged along the axial direction of the transmission mechanism of the governor, and the transmission mechanism of the oil mist separator is vertically connected with the transmission mechanism of the governor. The starter motor transmission mechanism is arranged symmetrically with respect to the axis of the speed governor transmission mechanism, and the two power output ends of the starter motor transmission mechanism are respectively connected to the corresponding starter motors along the axial direction. By designing an accessory transmission structure, the present invention can not only solve the problem of normal operation of the interior of the casing and the transmission system of the accessory, but also meet the requirements of the compact installation of the accessories on the casing of the casing.

Description

technical field [0001] The present invention relates to the field of aero-engine transmission systems, in particular, to an accessory transmission structure. Background technique [0002] When designing the transmission system of a certain type of aero-engine, multiple accessories are required to be installed on the casing, and each accessory needs to be designed for transmission. In order to reduce the external dimension of the casing of the casing, so as to make the weight of the casing lighter and meet the transmission requirements, the transmission device needs to be set up to meet the requirements of the transmission system and realize a compact structure. [0003] The design and layout of the existing transmission device are unreasonable, cannot meet the transmission requirements well, and lead to the heavy weight of the casing, which does not meet the requirements of the transmission system. SUMMARY OF THE INVENTION [0004] The present invention provides an access...
