A gas turbine includes at least one rotor assembly and at least one compressor casing. The compressor casing has at least one inner compressor casing chamber for arranging the rotor assembly and at least one outer compressor casing chamber for tempering the compressor casing. The inner and outer compressor casing chambers are separated from each other by a separating casing wall. The outer compressor casing chamber has at least one boundary casing wall. The boundary casing wall and the separating casing wall are oppositely spaced such that the outer compressor casing chamber is formed. The boundary casing wall has at least one inlet opening for leading in an inlet tempering gas flow with tempering gas into the outer compressor casing chamber such that a tangential material temperature variation of the compressor casing is reduced in comparison to a non tempered compressor casing.

An oil bearing to support a rotor of a turbine, especially of a gas turbine, wherein the rotor extends along a rotor axis coinciding with a bearing axis, has at least one oil bearing pad being lubricated by oil, including an oil sump suitable and located to collect the oil from the bearing pads by forces of gravity, including a drain system of the oil sump to conduct the oil away from the oil sump. The drain system includes at least three drain openings of the oil sump, wherein a first drain opening joining a first drain line is located between 4 o'clock and 5 o'clock according to the bearing axis, wherein a second drain opening joining a second drain line is located between 5:30 and 6:30, wherein a third drain opening joining a third drain line is located between 7 o'clock and 8 o'clock.

A bearing vibration measuring device for a turbo machine in which an outer housing and an inner housing are held concentrically at a distance from one another by way of at least one strut is provided. A bearing housing is disposed which is accessible from the outer housing through a radially extending access hole in the strut, the device includes a rod with an inner longitudinal end and an outer longitudinal end facing away from the inner longitudinal end, the rod being housed in access hole and being fastened at the inner longitudinal end to the bearing housing and including at least one vibration sensor on the outer longitudinal end.
