摘要： A hub assembly includes an inner rotatable hub having inboard and outboard axial ends, a radial flange extending outwardly from the outboard axial end and connectable with the wheel, an inner circumferential surface, and an opposing outer circumferential surface providing inboard and outboard inner races. An outer hub is disposed about the inner hub, connectable with the chassis and has inboard and outboard axial ends, an outer circumferential surface and an inner circumferential surface. The inner surface provides inboard and outboard outer races and a central surface section extending between the two outer races. First and second sets of rolling elements are disposed between the inner and outer races. One or more sensors are each disposed on the central surface section of the outer hub and are each configured to sense strain within the outer hub generated by the rolling elements.

The rotor is extended along an axial direction co-directional to a centerline axis of the rotor. The bearing system includes a body from which a plurality of first support members is each extended, and wherein the plurality of first support members is spaced apart from one another along the circumferential direction. Each first support member includes a first axial support arm extended along the axial direction and a first radial support arm extended from the first axial support arm along a radial direction. The first radial support arm is configured to position a bearing element in contact with a bearing surface at the rotor.

摘要： A method for producing bearing components includes providing a first bearing component, a second bearing component, a first production line, and a second production line. The first production line has a first grinding machine, a first honing machine, a first measuring unit, and a first conveyor unit. The second production line has a second grinding machine, a second honing machine, and a second conveyor unit. The method also includes grinding and honing the first bearing component, measuring a first dimension of the first bearing component, grinding and honing the second bearing component, and combining the first bearing component and the second bearing component to form a roller bearing or a slide bearing. The first production line and the second production line are operated in a synchronized manner such that the second grinding machine or the second honing machine is operated under closed-loop control using the first dimension.

摘要： A grease composition includes base oil, a thickener, and an inorganic additive. The base oil is a poly-α-olefin having a base oil kinematic viscosity of 15 to 50 mm2/s at 40° C. The thickener is a diurea expressed by Structural Formula (1). The content of the thickener is 10 to 22 mass % with respect to the total amount of the base oil and the thickener. The inorganic additive is a mixture containing sepiolite and bentonite, and is organically modified. The content of the inorganic additive is 2 to 20 mass % with respect to the total amount of the base oil and the thickener. R1—NHCONH—R2—NHCONH—R3   (1)

摘要： A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.

摘要： A rolling element bearing includes a plurality of rolling elements, a bearing inner ring and a bearing outer ring. The rolling elements are arranged circumferentially around an axis, and radially between the inner ring and the outer ring. The inner ring includes a plurality of first passages, a second passage and a channel that extends axially into the inner ring. The first passages are arranged circumferentially around the axis. The first passages respectively extend axially through the inner ring from a plurality of first passage inlets to the channel. The second passage includes a second passage inlet that is substantially axially aligned with one of the first passage inlets. The second passage extends radially through the inner ring to a second passage outlet.
