A sliding member according to an aspect of the present disclosure includes: a sliding member body containing a metal as a main component; and an outer layer laminated directly on a surface of the sliding member body and containing a crosslinked fluorine resin as a main component, and an arithmetic average roughness Ra1 of a surface having a waveform obtained by extracting a frequency component of a region having waviness having a frequency of not lower than 0.1 μm and not higher than 100.0 μm on a surface of the outer layer through fast Fourier transform processing, and performing inverse Fourier transform processing on data of a frequency component of a region having waviness having a frequency of not lower than 0.1 μm and not higher than 10.0 μm out of the extracted frequency component, is not greater than 0.035 μm.

A pitch bearing for coupling a rotor blade to a hub of a wind turbine includes an outer race mountable to the hub and an inner race rotatable relative to the outer race and mountable to the rotor blade. The inner race is formed by first and second ring components, each of the first and second ring components having an outer annular face and an inner annular face. The first and second ring components are joined together at the inner annular faces such that the inner annular faces are opposed and opposite each other. A layer of friction enhancing material is inserted/disposed between the opposed inner annular faces, the friction enhancing material including an abrasive particulate component that increases a coefficient of friction to minimize slippage between the first and second ring components.

In an embodiment, a bearing including a generally cylindrical sidewall having a thickness, t.sub.SW; a circumferentially extending feature projecting radially outward from the generally cylindrical sidewall, wherein the circumferentially extending feature has an axial height of at least about 2.0 t.sub.SW; and a flange disposed at an axial end of the generally cylindrical sidewall and spaced apart from the circumferentially extending feature. In another embodiment, an assembly including a first component comprising an aperture; a second component coaxial with respect to the first component; and a bearing disposed axially between the first and second components and at least partially within the aperture of the first component, wherein the first and second components are spaced apart from one another by a distance, D, and wherein the bearing is visible from a side elevation view along the entire distance, D.

A continuous hot bonding method for producing a bi-material strip with a strong bond therebetween is provided. The method comprises sanding a first strip formed of steel; and applying a layer of first particles, typically formed of copper, to the sanded first strip. The method next includes heating the first strip and the layer of the first particles, followed by pressing a second strip formed of an aluminum alloy onto the heated layer of the first particles. The aluminum alloy of the second strip includes tin particles, and the heat causes the second particles to liquefy and dissolve into the melted first particles. The first particles and the second particles bond together to form bond enhancing metal particles, which typically comprise bronze.

An overlay of a sliding component, such as a sliding component for an engine, may provide a bearing surface against a steel journal, for example. The overlay may include intermetallic particles disposed in a matrix including tin (Sn). The matrix may be formed by electroplating. Examples of intermetallic particles include, but are not limited to, aluminides and nickel aluminides. The matrix may include an electroplated matrix of tin and/or a tin alloy.

A component of a rolling-element bearing, such as a bearing inner ring having an inner ring flange, a bearing outer ring having an outer ring flange or a rolling element having an end surface, includes a solid slide layer having a lower coefficient of friction than a material to which the slide layer is attached which slide layer reduces frictional contact between the component and another component against which the slide layer slides during bearing operation.

A satellite dispenser is disclosed. In various embodiments, a satellite dispenser as disclosed herein includes a dispenser body defining an interior cavity configured to receive a payload; and a composite guide rail comprising a groove configured to receive at least a portion of a payload, the composite guide rail having an orientation that substantially aligns a longitudinal axis of the groove with an ejection axis of the dispenser.

A pitch bearing for coupling a rotor blade to a hub of a wind turbine includes an outer race mountable to the hub and an inner race rotatable relative to the outer race and mountable to the rotor blade. The inner race is formed by first and second ring components, each of the first and second ring components having an outer annular face and an inner annular face. The first and second ring components are joined together at the inner annular faces such that the inner annular faces are opposed and opposite each other. A layer of friction enhancing material is inserted/disposed between the opposed inner annular faces, the friction enhancing material including an abrasive particulate component that increases a coefficient of friction to minimize slippage between the first and second ring components.

A method for producing a component of a sliding bearing includes a) providing a metal bolt with a cylindrical lateral surface and two end faces; b) coating the lateral surface of the bolt with a soldering flux or solder material; c) providing a metal sheet made of bronze and forming it into a cylindrical sleeve having a longitudinal slot, wherein a first side of the metal sheet forming an inside is coated with a solder material or a soldering flux before or after the forming process, either the lateral surface of the bolt or the inside of the sleeve having soldering flux; d) sliding the sleeve onto the lateral surface of the bolt; e) integrally bonding the lateral surface and the sleeve soldering; f) optionally closing the longitudinal slot by welding; and g) optionally machining a second side of the metal sheet facing away from the bolt.

A satellite dispenser and method of using same are disclosed. In various embodiments, a satellite dispenser as disclosed herein includes a dispenser body defining an interior cavity to accommodate a payload; and a plurality of externally adjustable restraints positioned within the interior cavity and configured to be extended further into the interior cavity by actuation of a manual interface external to the interior cavity.
