摘要： A photographing step of obtaining an original image by photographing a part or all of a sliding surface using a camera is performed and then an imaging process of detecting machining marks on the original image is performed; a detecting step of obtaining a detection image is performed; and an evaluating step of estimating a difference of a rotation torque of the raceway ring member with respect to another raceway ring member on the basis of the detection image in a direction of relative rotation between the raceway ring member and the other raceway ring member when a rolling bearing is constituted by combining a raceway ring member with the other raceway ring member is performed.

摘要： Provided is a self-aligning roller bearing for supporting a main shaft of a wind power generator, the self-aligning roller bearing including an inner ring, an outer ring, two rows of rollers, and retainers. Each of the rollers has an outer peripheral surface formed with a DLC coating having a multilayer structure. The DLC coating has a film thickness of 2.0 μm or larger. A base material of each of the rollers has an external surface having a surface roughness of Ra≤0.3 and RΔq≤0.05. The DLC coating having the multilayer structure includes layers having stepwisely increasing film hardnesses such that a layer situated closer to outside has a higher hardness.

摘要： A method for coating a component, the method including the steps of depositing, by a thermal spraying process, simultaneously a first material and a second material on a surface of the component to form a rough coating, wherein the first material is of higher hardness than the second material and removing a layer of the rough coating such that the second material plastically deforms and produces a finished coating having a finished surface with an Rz value of less than 2 μm.

摘要： There are provided: a linear motion guide device, which enhances workability of raceway surfaces and is capable of reducing production cost; and a production method for the linear motion guide device. For this purpose, a linear motion guide device includes a guide rail (1), a slider (2), and a plurality of rolling elements (4), and the guide rail (1) and the slider (2) individually have raceway surfaces (11, 21), which form a rolling path (3) of the rolling elements (4), at positions opposite to each other. Then, the rolling elements (4) are disposed in the rolling path (3), and the slider (2) moves with respect to the guide rail (1) via the rolling elements (4). The raceway surface (21) of at least one of the slider (2) and the guide rail (1) is composed of: a first raceway surface (21A); and second raceway surfaces (21B) extending on both sides of the first raceway surface (21), and surface roughness of the second raceway surfaces (21B) is set rougher than surface roughness of the first raceway surface (21A).

摘要： A bearing for a gas turbine engine may comprise a squeeze film damper. A bearing housing may comprise a roughened surface. The roughened surface may increase friction between the bearing housing and the oil in the squeeze film damper. The increased friction may increase the damping force in the squeeze film damper. The increased damping force may prevent oil inertia, and prevent resonant vibrations.
