Abstract: A high-cycle, short range-of-motion linkage apparatus is provided for actuating a positioning device. The linkage apparatus includes a pivot member having a head portion configured to receive by plastic deformation a bearing assembly therein. The head portion defines a bore therein having a substantially cylindrical inner surface that defines an inner diameter having a first center point. The head portion further defines a truncated arcuate outer surface, a portion of which defines a radius of curvature and a second center point. A stem having a central axis extends from the pivot member along the central axis in a first direction. The second center point is offset from the first center point in the first direction and a distance between the first center point and the second center point, measured along the central axis, is in the range of up to about 33% of the radius of curvature.

Abstract: A spherical plain bearing includes an outer ring having a concave interior spherical surface, and an inner member having a convex exterior spherical surface. The inner member is pivotally disposed in the outer ring such that the inner member and the outer ring are angularly misalignable relative to one another. The spherical plain bearing includes an angular misalignment restraint system which includes an inner member restraint feature on the inner member and an outer ring restraint feature on the outer member. The first and second portions are spaced apart when the inner member and the outer ring are angularly misaligned relative to one another by less than a predetermined maximum angle θ, and come into abutment when the inner member and the outer ring are angularly misaligned relative to one another by angle θ. The abutment prevents any further relative angular misalignment of the inner member and the outer ring.

Abstract: A spherical bearing includes an inner member that has an exterior surface extending a first width between axial ends thereof and having a first central plane located equidistant between the axial ends. The spherical bearing includes an outer member with a inner surface having a maximum inside diameter at an apex plane and extending a second width between opposing ends thereof and having second central plane located equidistant between the ends thereof. The inner member is disposed in an interior area of the outer member. The first central plane is coplanar with the apex plane and is axially offset from the second central plane. One of the opposing axial ends of the inner member is located entirely in the interior area and axially inward from ends of the outer member when the inner member is angularly misaligned relative to the outer member at non-zero angles up to 7 degrees.

Abstract: A composite material having an alloy matrix including titanium, aluminum, niobium, manganese, boron, and carbon is disclosed. The composite material includes, by atomic percentage, 40.0% to 50.0% Al, 1.0% to 8.0% Nb, 0.5% to 2.0% Mn, 0.1% to 2.0% B, and 0.01% to 0.2% C. The composite material is doped with a solid lubricant such as MoS2, ZnO, CuO, hexagonal boron nitride (hBN), WS2, AgTaO3, CuTaO3, CuTa2O6, or combinations thereof. Components composed of the composite material exhibit increased ductility at room temperature and reduced fracture tendency, resulting in improved durability.

Abstract: A loader slot bearing includes an annular housing having first and second axial surfaces and an interior area extending therebetween. The interior area has a first inner surface that extends between the first and second axial surfaces. A portion of the inner surface is a first bearing surface that has a spherical contour. A slot extends partially into the first inner surface from the first axial surface. The slot has a first width. The annular housing is manufactured from a precipitation hardened corrosion resistant stainless steel. The loader slot bearing includes a truncated ball that is positioned in the slot and rotated so that the truncated ball is rotatably retained by the first bearing surface. The truncated ball is angularly misalignable relative to the housing and is manufactured from a 440C stainless steel. A dry lubricant is applied to the spherical exterior surface of the truncated ball.

Abstract: A loader slot bearing includes a housing and a truncated ball. The housing has an interior area that is defined by an inner bearing surface which has a concave contour defining a circumference. A single slot extends axially partway into the inner bearing surface and has a slot arc section area extending axially inward. The slot arc section area has a first circumferential slot-end, a second circumferential slot-end, and a slot arc length measured between the first circumferential slot-end and the second circumferential slot-end. A ratio of the slot arc length to the circumference of the interior area is about 0.20 to 0.35. The truncated ball has a convex exterior surface. The truncated ball is positioned in the slot and rotated so that the truncated ball is rotatably retained by the inner bearing surface. The truncated ball is angularly misalignable relative to the annular housing.
