FIELD: machine building.SUBSTANCE: proposed electric starter is intended for starting ground-based gas turbine engine. It is equipped with the system of cooling stator by oil from gas turbine engine oil system. Said system is composed of barrel accommodating stator winding while barrel outer side has helical channel A to transfer oil in starting. Said barrel is communicated with delivery side of system feeding oil for gas turbine bearings lubing and cooling via inlet union and pipeline. The last coil of helical channel A is communicated via outlet union and pipeline with main oil discharge pipeline draining oil into gas turbine engine oil system. Tightness of said helical channel A is ensured by seal rings fitted on barrel outer side, at surfaces outside said helical channel, two on every said side.EFFECT: simplified design.1 dwg |
