摘要： A bearing unit of a yawing system of a wind turbine having a tower and a nacelle connected by the yawing system. The bearing unit includes an adjuster element moveably secured to the bearing unit, a body element translatable relative to the adjuster element, a bearing element in contact with the body element, and a biasing means positioned between the body element and the adjuster element for applying a tension force to the bearing unit. The adjuster element adjusts the tension force applied to the bearing unit through translation of the body element, and respective surfaces of the adjuster element and the body element are visible during use.

摘要： A half bearing has a concave portion, a concave portion, and a concave portion penetrating from the outer circumferential surface to the inner circumferential surface, and the washer has a convex portion, a convex portion, and a convex portion on the inner circumferential surface side. The washer is moved to the outer circumferential surface side of the half bearing in a bent state, the convex portion is inserted into the concave portion, the convex portion is aligned with the position of the concave portion, and the convex portion is aligned with the position of the convex portion. Next, when the half bearing returns to its shape before being bent, the convex portion is accommodated in the concave portion, and the convex portion is also accommodated in the concave portion. Even if an axial force acts on the sliding bearing, the protrusion, the protrusion, and the protrusion engages with the concave portion, the concave portion, and the concave portion, so that the washer and the washer are not detached from the half bearing.

摘要： This half thrust bearing having a half-ring shape has: a sliding surface for receiving force in the axial direction; a back surface opposed to the sliding surface; and a resin covering layer on the sliding surface. The half thrust bearing is characterized in that the thickness of the resin covering layer is greatest at the circumferential central part of the half thrust bearing, and becomes lesser toward both circumferential ends of the half thrust bearing. The present invention also pertains to a thrust bearing, a bearing device, and an internal combustion engine.

摘要： A bushing includes a body and a plurality of lobes extending radially outward from the body. The plurality of lobes may include a first lobe, a second lobe, and a third lobe. The third lobe may include a material with a lower coefficient of friction than a material of the first lobe and the second lobe. A bushing assembly may include an inner member, an outer member disposed, and a bushing disposed at least partially between the inner member and the outer member. The bushing may include a first lobe, a second lobe, and a third lobe. The third lobe may include a material with a lower coefficient of friction than a material of the first lobe and the second lobe.
