GAS TURBINE ENGINE SUPPORT

摘要

FIELD: engines and pumps.SUBSTANCE: ball bearing and drive gear with collar are fitted on compressor rotor shaft in engine support. Oil feed device under drive gear coupling nut with slots is arranged between gear collar and thrust ledge while oil feed nozzle is located there ahead. Spacing between drive gear collar and thrust stop L1=1.1-2.5L2, where L2 is axial length of coupling nut. Lock of coupling nut features T shape and is fitted in mating T-shape groove of rotor shaft.EFFECT: simplified design, decreased weight of oil feed device.3 cl, 4 dwg
