摘要： A method for producing a rolling bearing component includes providing a rolling bearing component formed from a rolling bearing steel, heating the rolling bearing component to form an austenitic microstructure, and cooling the rolling bearing component in a warm salt bath to a temperature below a martensite start temperature of the rolling bearing steel. The rolling bearing component has a wall thickness or a diameter of at least 85 mm at at least one point and includes a martensitic microstructure in an edge layer region and a microstructure consisting of pearlite or upper bainite in a core region after the cooling. A rolling bearing component produced by the method and a rolling bearing comprising the rolling bearing component are also disclosed.

摘要： A torque limiter for a drive train includes a rotational axis, a first cover disc and a second cover disc, a central disc arranged axially between the cover discs, a first friction lining and a second friction lining, a radially outer connector and a radially inner connector, and a spring element. The first friction lining is for frictionally locking torque transmission between the first cover disc and the central disc, and the second friction lining is for frictionally locking torque transmission between the second cover disc and the central disc. The radially outer connector is permanently connected to the cover discs in a torque-transmitting manner, and the radially inner connector is permanently connected to the central disc in a torque-transmitting manner. The spring element is arranged between the central disc and the first friction lining or the second friction lining.

摘要： A torque converter includes a front cover arranged to receive a torque and a lock-up clutch engaged with the front cover. The lock-up clutch includes a reaction plate, a clutch plate, and an anti-rattle plate. The reaction plate is fixed to the front cover and includes a plurality of windows circumferentially spaced from each other. The clutch plate includes a plurality of tabs each engaged with the reaction plate via one respective window. The anti-rattle plate is fixed relative to the front cover and engaged with each of the plurality of tabs in the corresponding windows.

摘要： A separating clutch for a drive train of a motor vehicle includes a torque forwarding component, an outer multiple disc carrier fixed to the torque forwarding component for conjoint rotation, a first plurality of friction discs, a second plurality of friction discs arranged to transmit torque through a non-positive connection with the first plurality of friction discs, a pressing element having a first side facing the friction discs and a second side, opposite the first side, facing away from the friction discs, and a restoring spring. The pressing element is for axially displacing a one of the first or second plurality of friction discs to realize the non-positive connection, and the restoring spring contacts the pressing element for canceling the non-positive connection. The restoring spring engages through and behind the first side from the second side in a positively locking connection with the pressing element.

摘要： A strut bearing includes an upper case, a lower case, and a polygonal annular thrust bearing disk disposed axially between the upper case and the lower case. In some example embodiment, the polygonal annular thrust bearing disk has a first contact face and a second contact face in contact with the upper case, and a third contact face and a fourth contact face in contact with the lower case. In an example embodiment, the upper case has a first raceway surface in contact with the first contact face and a second raceway surface in contact with the second contact face, and the lower case has a third raceway surface in contact with the third contact face and a fourth raceway surface in contact with the fourth contact face.

摘要： A coil system, including: pairs of planar coils vertically stacked in a vertical direction, each pair of planar coils including a first planar coil including a first outer turn and a second planar coil including a second outer turn overlapping the first outer turn and laterally offset from the first outer turn; and pairs of vertically stacked thermal conductor tracks, each pair of thermal conductor tracks including a first track and a second track overlapping the first track, laterally offset from the first track, and overlapping the first outer turns of the pairs of planar coils. The pairs of thermal conductor tracks are DC isolated from pairs of planar coils. The first outer turns and the second outer turns of the pairs of planar coils form a first comb-like structure. The plurality of pairs of thermal conductor tracks form a second comb-like structure engaged with the first comb-like structure.

摘要： The disclosure relates to a threaded nut of a ball screw, the threaded nut having an inner sleeve made of sheet metal and an outer sleeve made of sheet metal, which are nested axially in one another to form a nut sleeve. The nut sleeve is provided with a thread, which is formed helically about a longitudinal axis of the threaded nut and which forms, on the inner circumference of the nut sleeve, a ball groove wound helically about the longitudinal axis of the threaded nut and, and on the outer circumference of the nut sleeve, a helically wound outer ridge.

摘要： A method is for producing a wet-running friction paper, at least containing a fiber fraction consisting of at least one type of fiber, a fraction of at least one filler, and a fraction of a binder based on phenol resin. The fiber fraction, the filler fraction and the binder dissolved as a phenolate solution are processed together in a paper production process to form a pulp, and the binder is subsequently precipitated by means of a precipitating agent, preferably diluted sulfuric acid, and the pulp applied to a long screen is dried and cured while the temperature is raised.
