FIELD: motors and pumps.
SUBSTANCE: low-pressure turbine of gas-turbine motor containing high-pressure turbine located in front of low-pressure turbine, and exhaust collector casing located behind low-pressure turbine. Low-pressure turbine includes rotor being fixed to low-pressure pivot, low-pressure shaft and frictionless bearing 1, which is mounted on the aforesaid low-pressure shaft and provides support for high-pressure pivot coupled with high-pressure turbine rotor. Turbine also includes frictionless bearing 2 mounted on low-pressure pivot behind frictionless bearing 1. Frictionless bearing 2 ensures central alignment of low-pressure pivot regarding collector casing and corrugation system being between bearing 1 and 2. Corrugation system enables low-pressure shaft moving by means of low-pressure pivot.
EFFECT: easy dismantling of low-pressure turbine.
