An exhaust-side journal bearing for supporting a gas turbine rotor is disposed inside a bearing box. The bearing box is supported by a strut which extends inward from an exhaust casing, and a seal ring having an annular inner peripheral end is disposed on the bearing box. Executed during a maintenance work are: a bearing adjustment step of displacing a bearing surface of the journal bearing relative to the bearing box in a perpendicular direction perpendicular to the axial direction; and a seal ring adjustment step of displacing the inner peripheral end of the seal ring relative to the bearing box in accordance with the direction of displacement and the amount of displacement of the bearing surface.

A quick release pillow block bearing assembly has end pieces, a center bearing housing carrying a bearing, and quick release pins for retaining the bearing housing with the end pieces. The invention enables replacement and or repair of the bearing and its counterparts easily, efficiently, and less often. The user need only remove the quick release pins remove the bearing housing and thereby gain access to the housing, which also provides access to the bearing/shaft and counterparts. Upon removal of the quick release pins, the center housing may be removed from the structure, while the end pieces stay in place, allowing one to remove and install the bearing quickly. It also enables removal of the shaft in seconds, thus permitting easy and quick replacement of worn sections of the bearing.

A method changes a sliding bearing element of a rotor bearing of a wind turbine. The rotor bearing includes inner and outer ring elements, between which the sliding bearing element is arranged. The inner ring element and the outer ring element are rotatable relative to each other. A rotor hub is fastened to the inner ring element or to the outer ring element. The sliding bearing element includes multiple individual sliding bearing pads, each of which are releasably fastened to the inner ring element or outer ring element of the rotor bearing by at least one fastener. When changing the sliding bearing element, the individual sliding bearing pads are removed one after the other and replaced by new sliding bearing pads, wherein during the changing of the individual sliding bearing pads of the sliding bearing element, the inner ring element and the outer ring element are not disassembled.

The invention herein comprises a kit and method that may be used to replace damaged and worn stabilizer bearings in both the Echo and Delta Apache helicopter. The kit includes a removal assembly that includes a bolt coupled to a cutting means. Tightening of the bolt causes the cutting means to cut the damaged and worn bearing from its housing. A staking means is disclosed that allows the staking of a replacement bearing in the housing is provided. The staking assembly joins the replacement bearing to the housing so that it is tight. And, an installation assembly is disclosed that utilizes the bolt utilized in the cutting means coupled to a hex nut.

The present invention provides a transmission roller, a pin-teeth cycloid reducer with the same and a bearing. The transmission roller comprises a hollow roller which is made by spirally and closely winding a steel strip or a steel wire, and the length of the hollow roller remains unchanged when both ends thereof distributed along the axial direction are squeezed. When the hollow roller is subjected to external pressure, the ends thereof will not be easily damaged, and will not extend to the middle part during use, thus having a long service life.

Disclosed herein is a rescue bearing, in accordance with some embodiments. Accordingly, the rescue bearing comprises an outer ring, an inner ring, rolling elements, and fastening elements. Further, the inner ring comprises a middle portion and opposing side portions. Further, a first side portion of the opposing side portions extends axially from a first side end of the middle portion beyond a first outer ring edge of the outer ring. Further, a second side portion of the opposing side portions extends axially from a second side end of the middle portion beyond a second outer ring edge of the outer ring. Further, the inner ring is configured for receiving a shaft into a bore of the inner ring based on inserting the shaft into the bore. Further, the opposing side portions is configured to be fastened to the shaft using the fastening elements.

The invention relates to a planetary gearbox in a gas turbine engine wherein a plurality of planetary gears are each mounted on a planetary gear bearing journal by a slide bearing, characterized in that a bushing is arranged in an inner bore of at least one planetary gear, which bushing spatially separates the sliding surface of the slide bearing from the inner bore of the planetary gear and the bushing is designed as a replacement part, in particular as a sacrificial part. The invention also relates to a gas turbine engine.

For replacing in particular a used main bearing of a wind turbine, a bearing housing is first pulled axially off the main bearing along a rotor shaft, then the used main bearing is divided and disassembled. A new main bearing is assembled around the rotor shaft and the original bearing housing is pushed axially back onto the main bearing. During the replacement of the main bearing, the rotor shaft is supported on a machine carrier by means of a holding device, wherein the holding device is arranged at least partially in the region between a bearing seat and a hub-side end region of the rotor shaft.

The invention relates to a sliding bearing (9) comprising: an inner ring element (13); an outer ring element (14); at least one sliding bearing element (15), which is arranged between the inner ring element (13) and the outer ring element (14).

The sliding bearing element (15) has multiple sliding bearing pads (20), wherein the individual sliding bearing pads (20) each have a bearing surface (26), which is designed in the shape of a spherical cap.

A bearing assembly includes at least one inner ring and at least one outer ring, and at least one surface of the inner or outer ring is partially colored with an acid-free ink. If the at least one surface includes a surface defect such as a scratch in a black-oxide coating, the acid-free ink may be applied to the scratch to at least partially conceal it.
