Publication number: 20230258227Abstract: A radial foil bearing for supporting a shaft includes a sleeve-like bearing housing with an inner circumference and at least three foil packs distributed over the inner circumference and covering a portion of the inner circumference. Each of the at least three foil packs has an elastic corrugated foil resting against the inner circumference and a top foil. The elastic corrugated foil includes axially opposite side edges running in a circumferential direction and a narrowed portion disposed on at least one of the axially opposite side edges to reduce an axial width and a radial spring rigidity of the elastic corrugated foil at the narrowed portion. The top foil has an underside resting on the elastic corrugated foil and a top side forming a bearing surface for the shaft.Type: ApplicationFiled: June 9, 2021Publication date: August 17, 2023Applicant: Schaeffler Technologies AG & Co.

Patent number: 10458473Abstract: A cage segment of a rolling bearing, which cage segment has two side plates and two webs which are fixedly connected to one another, wherein the webs extend parallel to the axis of rotation of the rolling bodies of the rolling bearing, and in which cage segment the side plates and the webs form a pocket for receiving a rolling body. In order to be able to produce and assemble a cage segment of said type in an inexpensive manner, and in order to be able to ensure operation without jamming in an associated rolling bearing, it is provided that the two side plates on both sides of the pocket extend in a circumferential direction of the rolling bearing to such an extent that the side plates together with in each case one of the two webs form in each case one half-pocket for receiving a directly adjacent rolling body.Type: GrantFiled: August 22, 2016Date of Patent: October 29, 2019Assignee: Schaeffler Technologies AG & Co.

Patent number: 10145416Abstract: A bearing cage for receiving rolling elements is disclosed. In addition to two rings, the bearing cage also has a plurality of webs which run axially between the rings. In order to prevent the rolling elements from falling out of the pockets formed between the rings and the webs, the webs have a groove which runs in the direction of the respective web. When the rolling elements are inserted into the pockets, a tool engages into the groove and bends the edge region of the web in a direction of the rolling elements.Type: GrantFiled: February 10, 2015Date of Patent: December 4, 2018Assignee: Schaeffler Technologies AG & Co. KGInventors: Siegfried Mahler, Peter Zay, Hermann Geyer, Jorg Neukirchner

Publication number: 20170102033Abstract: The invention relates to a bearing cage (1) for receiving rolling elements (6). In addition to two rings (2, 3), the bearing cage also has a plurality of webs (4) which run axially between the rings (2, 3). In order to prevent the rolling elements (6) from falling out of the pockets (5) formed between the rings (2, 3) and the webs (4), the webs (4) are at least provided with a groove (7a) which runs in the direction of the respective web (4). When the rolling elements (6) are inserted into the pockets (5), a tool (9) engages into the groove (7a) and bends the edge region (11) of the web (4) in a direction of the rolling elements (6) inserted into the pockets (5).Type: ApplicationFiled: February 10, 2015Publication date: April 13, 2017Applicant: Schaeffler Technologies AG & Co.

Publication number: 20160069389Abstract: A rolling body guide element for a roller bearing, having an inner web (1) that is arranged between two adjacent rolling bodies in the installed state and forms a first and second connecting part wall (1a, 1b) facing a respective rolling body at the radial plane of the rolling body axes, a run-on structure (2) formed in the region of the respective connecting part wall to provide at least one roller run-on zone supporting the respective rolling body in the circumferential direction, and a radial guide structure (3) for radial guidance of the inner connecting part. According to the invention, the rolling body guide element includes first and second side edge pieces (4, 5) which, on sides of the rolling body guide element facing away from one another, rise up above the end faces of the adjacent rolling body and overlap these end faces.Type: ApplicationFiled: April 7, 2014Publication date: March 10, 2016Applicant: Schaeffler Technologies AG & CO.

Publication number: 20160003298Abstract: A cage section (36), particularly for a meander-shaped cage (12) of a rolling contact bearing (14, 15), including at least one cage part (10, 11, 11?) made of a Z-shaped bent sheet-metal strip (16, 17) with a first arm (20), a connecting part (18) and a second arm (22), wherein the first arm (20) and the second arm (22) are bent substantially perpendicularly to the sheet metal plane (23). The invention further relates to a method for producing a cage portion (36), particularly for a meander-shaped cage (12) of a rolling contact bearing (14, 15).Type: ApplicationFiled: February 3, 2014Publication date: January 7, 2016Applicant: SCHAEFFLER TECHNOLOGIES AG & CO.

Publication number: 20150377291Abstract: A cage part (1, 20, 40) for a rolling bearing cage (30), having a connecting part (3) extending in a longitudinal direction (Z), at the ends of which a first supporting arm (4) and a second supporting arm (5) are arranged, each of which extends beyond the connecting part (3) on both sides in a first transverse direction (X) perpendicular to the longitudinal direction (Z). The supporting arms (4, 5) each include two half arms (7, 8, 9, 10) angled in the opposite direction to one another away from the web (3) and which are offset with respect to one another in a second transverse direction (Y) perpendicular to the first transverse direction (X) and the longitudinal direction (Z).Type: ApplicationFiled: February 3, 2014Publication date: December 31, 2015Applicant: Schaeffler Technologies AG & Co.

Patent number: 4281038Abstract: The disclosure is of a substrate or supporting board for supporting printed ircuits and the method of its manufacture. The boards of the invention are preferably made of a high-temperature resistant thermoplastic, sensitized to receive a printed circuit element by the dispersion of coated iron or copper particles in the thermoplastic matrix. The coating is a bonding assistant.Type: GrantFiled: December 10, 1979Date of Patent: July 28, 1981Assignee: Preh, Elektrofeinmechanische Werke, Jakob Preh Nachf GmbH & Co.Inventors: Peter Ambros, Hermann Geyer

Patent number: 4036571Abstract: Iris leaves for optical components such as diaphragms or shutters are injection-molded, together with integral pivot pins, of thermoplastic resin which is given a mat appearance by a roughening of the mold-cavity surfaces. In the case of a composite leaf consisting of two legs articulated to each other, each leg is a curved foil whose cross-section tapers from its convex to its concave edge to facilitate relative swinging of the legs. The mold cavities are duplicated in confronting surfaces of coacting mold halves and open into deeper sprue channels whose junctions with the cavities are formed by converging slots in shearing bolts that are guided in transverse bores encroaching upon the convex cavity edges, a displacement of these shearing bolts by a distance greater than the foil thickness severing the molded leaves from the runners before the mold is opened.Type: GrantFiled: November 14, 1975Date of Patent: July 19, 1977Assignee: Jos. Schneider & Co. Optische Werke KreuznachInventors: Hermann Geyer, Albert Baab, Paul Himmelsbach
