摘要： A gas microturbine that includes a closed-loop oil distribution system that includes an oil reservoir, an oil- supply circuit, an oil-scavenge circuit, and a pump. The oil reservoir is configured to contain a provision of oil. The oil-supply circuit includes an inlet in communication with the oil reservoir and a first outlet in communication with a raceway of a turbine shaft bearing. The oil-scavenge circuit includes a first inlet in communication with the raceway of the bearing and an outlet in communication with the oil reservoir. The pump is coupled to either the oil- supply circuit or the oil-scavenge circuit and is configured to pump oil from the oil reservoir through the oil supply circuit to the first outlet of the oil- supply circuit and from the first inlet of the oil-scavenge circuit back to the oil reservoir. The first outlet of the oil- supply circuit is configured to atomize oil.

摘要： A damping arrangement (1) for damping radial vibrations in a rotating shaft (2), the damping arrangement (1) comprising at least one first damping element (3), at least one second damping element (4), and a bearing arrangement (5) operably engaging the first damping element (3) and the second damping element (4). The bearing arrangement (5) comprises a first bearing member (6), a second bearing member (7), and a reference (8). The first bearing member (6) is rotatably mounted on the shaft (2) so that radial movement of the shaft (2) is transferred to the first bearing member (6), and is operably connected to the second bearing member (7) by the first damping element (3) and by a first steering structure (9). The first steering structure (9) allows only reciprocating movement of the first bearing member (6), and the shaft (2), in a first radial direction (D1), and the first damping element (3) dampens the reciprocating movement in the first radial direction (D1) with respect to the second bearing member (7). The second bearing member (7) is operably connected to the reference (8) by the second damping element (4) and by a second steering structure (10) allowing only reciprocating movement of the second bearing member (7), the first bearing member (6), and the shaft (2), in a second radial direction D2. The second damping element (4) dampens the reciprocating movement in the second radial direction (D2) with respect to the reference (8).
