HELICOPTER TRANSMISSION TAIL SHAFT

摘要

FIELD: aircraft engineering.SUBSTANCE: tail shaft comprises horizontal section connecting main and mid gears and inclined tail section connecting the mid and tail gears. Shaft horizontal section consists of several parts including tubular sections and bearing assemblies. Connection assemblies of the shaft horizontal part tubular sections are provided with splined adapters fitted in bearing assemblies. Tubular section splined connector at first bearing assembly on the main gear side incorporates a plate clutch with splined flange to interact with splined tip of adjacent tubular section. Last tubular section connection to mid gear and shaft inclined tail part connection to mid gear and tail gear are made with the help of splined connectors with plate clutches. First tubular section is connected to main gear with the help of flange joint with plate clutch.EFFECT: fast preparation of helicopter to flight.3 dwg
