Abstract: A rolling bearing assembly, comprising at least a rolling bearing outer ring (4) of a rolling bearing, an intermediate element that surrounds the rolling bearing outer ring (4), and a housing part, into which the intermediate element (9) is inserted. The outer ring (4) is rotatably arranged in the intermediate element (9) and has a circumferential oil catching strip (6) at one of the end faces thereof, which oil catching strip is designed to convey oil into a contact zone formed between the outer ring (4) and the intermediate ring (9). A damping system having a damping recess is formed between the housing and the intermediate element (9).

Abstract: A roller bearing having two cooperating rolling parts of which one is of ceramic and the other of a steel. The steel part is of such structure and/or material and/or is so produced to cause residual compressive stresses to form beneath the contact surface of the steel part, at least in a load-free state, down to a depth.

Abstract: A revolving joint comprising at least one anti-friction bearing and an electromotive drive unit. The anti-friction bearing is in contact with at least one row of rolling bodies arranged in a row rotating the joint around the rotational axis of the anti-friction bearing. The rolling bodies are in contact with at least one race that can be driven to rotate by the drive unit.

Abstract: The aim of the method is to achieve a higher penetration depth of the diffusion element coupled with a greater depth of case hardening and a higher case hardening degree, whilst preventing an excessive enrichment of the case, thus obtaining an increased fatigue limit for the component. To achieve this, the full hardening of the component and the plasma-ion hardening of the case of the component are carried out in a common working step. The component is heated to a common hardening and diffusion temperature TH+D lying above the upper transformation temperature AC3, the component being held at the common hardening and diffusion temperature TH+D until the carbon in the component has fully austenitized and dissolved and until the case has been enriched to the desired degree by the diffusion element. The component is then quenched.

Abstract: A single-row or multi-row rolling bearing comprising thin-walled bearing races which are made of a martensitic, through hardened steel and have the following characteristics: a surface hardness of ?613 HV (56 HRC) in the area of the bearing face; a core hardness of ?285 HV (28 HRC); a difference of ?150 HV (9 HRc) between the surface hardness and the core hardness. The core hardness is reached at a depth ranging between 8 percent of the diameter of the rolling elements and 90 percent of the wall thickness on the bottom of the track. There is a ratio of ?20 between the diameter of a pitch circle Tk and the diameter of a rolling element DW.

Abstract: A machine element of steel with a martensitic microstructure and which at least in a load-free state, has thermochemically produced residual compressive stresses in the microstructure under at least a portion of the surface of the machine element, down to a depth from the surface of the element. The stresses are in an outer layer of the element which may be treated specially. The element may be one element of a rolling bearing.

Abstract: A method and apparatus for preparing a mat of predetermined thickness from spreadable material for ligneous-material wall boards is disclosed.

Abstract: The present invention relates to an apparatus for longitudinally aligning particles, such as chips during the manufacture of chipboards, into a preferred direction by means of parallel, vertical aligning plates spaced apart from each other. Sets of alternating spiked and solid discs are mounted above the vertical aligning plates intermeshing with them to prevent clogging and facilitates longitudinal alignment of the particles being fed. The solid discs may have different diameters to facilitate flow. Preloosening rollers are mounted above the aforementioned disc rollers at different levels to more uniformly distribute particles. The central preloosening rollers slightly overlap each other and rotate in opposite directions. Outer preloosening rollers also rotate in opposite directions.
