An Improvement Design of Middle Gear for a Turboshaft Engine Decelerator
XIE Wei-hong & LI Qun-li (China National South Aeroengine Co., Zhuzhou 412002)
This article introduces the middle gear composed of the first stage driven gear and the second stage driving gear sharing the same shaft. The middle gear has high risks of scrap of the fine-machined small gear shape and direction from electric beam welding. By improving the design of local construction and welding location, the problem is solved. Tests on 6～7 sample parts indicate that the improved electric beam welding has now limited effect on small gear shape and direction. The product quality has been greatly improved.
