A bearing support for a turbocharger, the bearing support including a body, a bore extending axially through the body and dimensioned to receive a bearing and a portion of a planet carrier, and a plurality of pilots. Each pilot may be formed on an external surface of the body, and each pilot may be machined for an interference fit with a different component of the turbocharger.

A tool assembly is provided for removing a component from a carrier. The component circumscribes and is mounted on the carrier. The tool assembly includes a tool head, an adaptor and an actuator. The tool head is configured to couple to the component. The adaptor extends longitudinally along a centerline between an adaptor first end and an adaptor second end. The adaptor is attachable to the tool head at the adaptor first end by a first quick coupler. The actuator includes a housing and a ram. The housing is attachable to the adaptor at the adaptor second end by a second quick coupler. The ram extends longitudinally along the centerline within the adaptor and the tool head to a ram distal end. The ram distal end is configured to engage the carrier.

Turbomachine output bearing support extending according to an axial direction, said support being formed by one and the same piece and comprising an annular inner wall having an inner side and an outer side, an annular outer wall and a twist support.

An assembly is provided for a piece of rotational equipment with an axis. This assembly includes a static structure, a bearing within a bore of the static structure, and a centering spring mounting the bearing to the static structure. The static structure is configured with the bore, a slot, a first slot surface and a second slot surface. The slot extends radially into the static structure from the bore. The slot extends axially within the static structure between the first slot surface and the second slot surface. The centering spring includes an annular hub and a mounting tab. The annular hub is within the bore. The mounting tab projects radially from the annular hub into the slot.

A bearing element for at least one adjustable guide vane of a turbomachine, in particular an aircraft engine, is provided. The bearing element comprising a porous matrix made of carbon and/or graphite and at least one metallic phase or a metal salt that is at least partially arranged inside the pores of the matrix, so that what results is a metal-infiltrated or a metal-salt-infiltrated material.

A disclosed fan drive gear system includes a sun gear rotatable about an axis of rotation, a plurality of intermediate gears rotatable about an intermediate gear rotation axis in meshing engagement with the sun gear and a ring gear circumscribing the intermediate gears. A bearing assembly supports at least one of the plurality of intermediate gears and includes a first beam extending in a first direction and a second beam extending from an end of the first beam in a second direction. The bearing surface supported on the second beam such that first and second beams are configured to maintain the bearing surface substantially parallel to the intermediate gear rotation axis during operation.

An internal combustion engine with a turbocharger according to an embodiment includes a cylinder block internally including a plurality of cylinders, a cylinder head disposed on top of the cylinder block, and internally including a plurality of exhaust flow passages through which exhaust air discharged from each of the plurality of cylinders flows, and the turbocharger including a rotational shaft, a turbine wheel, and a compressor wheel, the turbine wheel being disposed at one end of the rotational shaft, the compressor wheel being disposed at the other end of the rotational shaft. At least the turbine wheel of the turbocharger is arranged inside the cylinder head. The cylinder head internally includes a plurality of scroll passages for introducing the exhaust air flowing through the plurality of exhaust flow passages to the turbine wheel, the plurality of scroll passages including a first scroll passage for introducing the exhaust air from a first range in a circumferential direction of the turbine wheel to the turbine wheel, and a second scroll passage for introducing the exhaust air from a second range, which is different from the first range in the circumferential direction of the turbine wheel, to the turbine wheel.

An assembly is provided for a turbine engine. This turbine engine assembly includes a journal bearing and a filter. The journal bearing has an internal bearing bore. The filter is arranged within the internal bearing bore. The filter includes a tubular filter element and a first end cap. The tubular filter element extends axially along an axis between a first end and a second end. A perforated portion of the tubular filter element is radially disposed away from the journal bearing by a cavity. The first end cap is mounted to the tubular filter element at the first end. The first end cap is sealed radially against the journal bearing by a first interference fit.

A bearing assembly is provided. The bearing assembly includes an inner race configured to couple to a shaft, an outer race disposed around the inner race, and a housing disposed around the outer race. The housing and the outer race define an annulus and a buffer region, and the buffer region defines an axial boundary of the annulus.
