Patent number: 11624183Abstract: A profile assembly produced from a first profile and a second profile connected longitudinally by cold joining. Both profiles bear complementary clamping structures on long sides thereof facing toward one another for cold joining together. The clamping structure of the first profile comprises a clamping head formed on a web and forming an undercut on each side of the web by way of a greater extension in the profile transverse direction in relation to that of the web. The clamping structure of the second profile comprises a clamping head receptacle for accommodating a section of the clamping head and a clinching leg, formed on a profile-exterior leg of the clamping head receptacle, having a first profile arm protruding before cold joining and a second profile arm formed at an angle thereon, the free end of which engages behind the clamping head and, before cold joining, faces toward a clamping pocket of the first profile.Type: GrantFiled: March 12, 2020Date of Patent: April 11, 2023Assignee: OTTO FUCHS KOMMANDITGESELLSCHAFTInventors: Gerd Thomzick, Stefan Anders, Sebastian Kersten

Patent number: 11427890Abstract: A copper alloy having a high corrosion resistance for a wide range of different lubricants, in particular different base oils and a variation of lubricant additives. The property of a low corrosion tendency for different tribological systems is also combined with good mechanical properties, and a high strength in particular. The alloy has a low wear and coefficient of friction. The lubricant-compatible copper alloy is suitable for producing components that come in contact with lubricant and are exposed to friction stresses, such as gear components, for example synchronizer rings. A method for manufacturing such components and a gear having at least one such component is also disclosed.Type: GrantFiled: September 28, 2019Date of Patent: August 30, 2022Assignee: OTTO FUCHS KOMMANDITGESELLSCHAFTInventors: Hermann Gummert, Björn Reetz, Thomas Plett

Patent number: 11339814Abstract: A profile assembly having a first profile and having a second profile connected on its long side to the first profile, which two profiles each have a hook strip integrally formed on the long side, wherein the hook projection of the hook strip of the first profile points in the one direction, and the hook projection of the hook strip of the second profile points in the opposite direction, the hook strips brought into engagement with one another in a claw-like manner. The first profile has an anchoring channel following its longitudinal extent, and the hook strip of the second profile has a clamping strip which is integrally formed thereon, which hook strip is secured by its hook projection and its clamping strip in the anchoring channel of the other profile by a cold joining connection.Type: GrantFiled: February 8, 2018Date of Patent: May 24, 2022Assignee: OTTO FUCHS KOMMANDITGESELLSCHAFTInventors: Gerd Thomzick, Christoph Schulte, Hendrik Schliffke, Christian Adleff

Patent number: 10464118Abstract: A method for producing a contoured ring rolling product for a rotating application from a ring blank, with a ring rolling machine controlled in a process-monitored manner. At least one process window, extending over the rolling time, is defined in relation to preselected process parameters for the specific product on the basis of calibrating specimens brought into their final form by the ring rolling machine. The process window(s) monitored during the process is/are determined by the process parameters of calibrating specimens which produced rolled products meeting the requirements demanded of the ring rolling product. The preselected process parameters comprise at least two of ring growing rate, axial rolling force, radial rolling force, rolling time, and ring blank temperature.Type: GrantFiled: July 31, 2015Date of Patent: November 5, 2019Assignee: OTTO FUCHS KOMMANDITGESELLSCHAFTInventors: Thomas Witulski, Jörg Ihne, Stefan Teschner, Christof Müller
