摘要:
A bearing component part for use in a diffusion welding process, comprising a core part presenting a first circumferential surface, at least one annular part presenting a second circumferential surface, wherein the core part and the annular part are attached to and along each other in a circumferential manner through their first circumferential surface and second circumferential surface. The at least one annular part is substantially u-shaped in a cross sectional view, comprising two opposing sides connected by a base side together forming a space. The at least one annular part is arranged to receive a first material in the space formed by the u-shape.

A Lubricant comprises a carboxylic-acid-amide which is based on aliphatic unbranched, alicyclic and/or aromatic chains with chain length from 2 to 60 carbon atoms.
摘要:
A bearing component formed from a bearing steel, wherein the component has an outer surface and comprises through-hardened bainite and/or martensite and has a substantially homogeneous chemical composition, at least a part of the bearing component having a compressive residual stress profile comprising −25 to −1000 MPa at the near surface, wherein the near surface is defined as a region 500 microns or less below the outer surface.
摘要:
A method to join a first material and a second material by diffusion welding, wherein a third material is put in between the first material and the second material during the joining process.
摘要:
A system for re-lubricating a machine element, which comprises an analysis device arranged to determine which part of a lubricant that is being used to lubricate the machine element has been depleted and to generate a signal indicative thereof. A lubrication element is arranged to automatically re-lubricate the machine element only with the part of the lubricant that has been depleted in response to the signal.
摘要:
A process for inducing a compressive residual stress in a surface region of a steel component, the process comprising a heat treatment having the following steps: (i) providing a component comprising a steel composition; (ii) induction heating at least a part of the component followed by quenching said at least part, wherein the hardness in a surface region of the component is increased; and (iii) subsequently performing a martensite and/or bainite through hardening step to obtain a microstructure comprising martensite and/or bainite.
摘要:
A use of a lubricant comprising at least one reaction product of mono-di- and/or poly-isocyanate with unbranched and/or branched, unsaturated and/or saturated, alicyclic poly-amine with carbon numbers from 5 to 24, at least between at least two elements, which are moveable against each other.

A use of a lubricant comprising at least one reaction product of mono-di- and/or poly-isocyanate with unbranced and/or branced, unsaturated and/or saturated, alicyclic poly-amine with carbon numbers from 5 to 24, at least between at lease two elements, which are movable against each other.
摘要:
A system comprising at least one component for an application in which the at least one component is subjected to Hertzian stress or alternating Hertzian stress or altering Hertzian stress in combination with structural stress, and at least one sensor that is arranged in situ to monitor atomic hydrogen permeation through at least part of the at least one component.
