航空发动机附件传动系统研究
摘要
现代航空发动机功率和附件转速日益提高,需要高转速的附件传动系统与之匹配。高转速的附件传动系统,不仅能够传递更大的功率,而且减轻发动机的重量,提高推重比。
首先,论文阐述了附件传动设计的基本方法,对航空附件传动系统的特点进行分析,研究了将起动传动系统与高转速附件传动系统联结成一个传动系统的结构设计方法,并阐明了实现这种设计的关键是高速斜撑超越离合器。论文分析了将起动传动系统与附件传动系统联结成一个传动系统的关键件——超越离合器的工作原理。滑油系统是航空发动机机械系统的重要组成部分。随着中国航空发动机的发展,对其滑油系统的研究逐步深入,在系统的设计原理“系统热分析”系统组成部件“润滑油”系统检测等几个方面正在从仿制走向自行研制的道路。对发动机滑油系统的发展现状进行了分类描述,总结了未来发动机研制滑油系统的发展方向。

Abstract
Modern aviation engine power and accessories speed increasing, need high speed matching accessories for transmission system. High speed transmission of attachment, not only can deliver more power, and reduce the weight of the engine, increase in esteem.
First of all, the thesis expounds the attachment transmission design, the basic method to analyze the characteristics of aviation accessory drive system; Will start transmission system is studied with high speed accessory drive system connected into the structure of a drive system design method, and illustrates the key is to realize the design of high-speed sprang overrunning clutch. Papers will start transmission system are analyzed and the accessory drive system connected into a transmission key-module, overrunning clutch working principle; Lubricating oil system is an important part of mechanical aircraft engine! With the development of China's aviation engine, the lubricating oil system of research gradually thorough, the design principle of the system “system thermal analysis system\nents “lubricating oil\are developed by from imitation to road! Development status of engine lubricating oil system are classified description, summarizes the development direction of engine lubricating oil system in the future。
