Patent number: 7270892Abstract: The invention describes a friction bearing with a steel support shell and a lead-free bearing metal layer on the basis of copper with the main alloy elements of tin and zinc, which layer is applied to the support shell. In order to combine advantageous sliding properties with favorable mechanical resilience it is proposed that the bearing metal layer has a share of tin of 2.5 to 11% by weight and a share of zinc of 0.5 to 5% by weight, with the sum total of the shares of tin and zinc being between 3 and 13% by weight.Type: GrantFiled: February 24, 2006Date of Patent: September 18, 2007Assignee: Miba Gleitlager GmbHInventor: Robert Mergen

Patent number: 7181842Abstract: A method of producing a workpiece forming at least one bearing eye is described, which is divided in the region of the bearing eye along an intended fracture point through a fracture separation, the bearing eye being coated with an anti-friction coating after assembly of the parts. In order to achieve a high load capacity, it is suggested that the bearing eye be processed for a precise fit after assembly of the parts obtained through the fracture separation of the workpiece, before the anti-friction coating is applied to the processed bearing eye surface in a thickness corresponding to the final dimensions.Type: GrantFiled: October 3, 2003Date of Patent: February 27, 2007Assignee: Miba Gleitlager GmbHInventors: Ulf G. Ederer, Thomas Rumpf, Elisabeth Schneiderbauer

Patent number: 7178238Abstract: A method of producing a workpiece (1) having at least one bearing eye (2) is described, the bearing eye (2) being coated with an anti-friction coating (4), which forms a running surface deviating from a circular cylinder. In order to provide advantageous production conditions, it is suggested that the bearing eye (2) be processed for a precise fit to a circular cylinder, before the anti-friction coating (4) is galvanically deposited on the processed bearing eye surface (3) to form the running surface in a varying thickness which corresponds to the final dimensions.Type: GrantFiled: October 3, 2003Date of Patent: February 20, 2007Assignee: Miba Gleitlager GmbHInventors: Thomas Rumpf, Elizabeth Schneiderbauer, Helmut Spieβberger

Patent number: 7156149Abstract: A method is described for producing a stratified composite material, with a layer of sinterable solids particles being applied to a strip-like metal carrier and being sintered with liquid phase by the supply of heat continuously in the forward feed direction. In order to provide simplified production conditions it is proposed that the metal carrier is heated continuously in the forward feed direction with a temperature profile which decreases towards lower temperatures from a maximum temperature above the melting temperature of the solids particles in the region of a surface layer receiving the particle layer towards a core layer of the metal carrier, and that the particle layer is sintered at least in a layer resting on the metal carrier by a heat transmission from the heated metal carrier.Type: GrantFiled: June 1, 2005Date of Patent: January 2, 2007Assignee: Miba Gleitlager GmbHInventors: Robert Mergen, Günter Kutzik

Patent number: 7078110Abstract: A slide bearing is described with a bearing metal layer on copper basis as applied to a carrier and a running layer made of an alloy of aluminum and tin which is applied physically onto the bearing metal layer in vacuum. In order to combine favorable resistance against wearing with a low inclination towards jamming with advantageous tribological properties it is proposed that the bearing metal layer consists of an alloy with 4 to 8% by weight of tin, 0.6 to 1% by weight of silver, 1 to 2% by weight of an iron phosphide and 0 to 0.15% by weight of carbon, preferably in the form of graphite, and the remainder of copper.Type: GrantFiled: December 10, 2004Date of Patent: July 18, 2006Assignees: Miba Gleitlager GmbH, Taiho Kogyo Co., Ltd.Inventors: Walter Gärtner, Hubert Lang, Soji Kamiya, Takashi Tomikawa

Publication number: 20040064948Abstract: A method of producing a workpiece having at least one bearing eye is described, the bearing eye being coated with an anti-friction coating made of an alloy of a harder alloy component and a softer alloy component. In order to achieve an advantageous load capacity, it is suggested that the bearing eye be processed for a precise fit to a circular cylinder before the anti-friction coating is applied to the processed bearing eye surface in a thickness corresponding to the final dimensions, the proportion of the softer alloy component in the deposited alloy being increased with increasing coating thickness.Type: ApplicationFiled: October 3, 2003Publication date: April 8, 2004Applicant: Miba Gleitlager GmbHInventors: Thomas Rumpf, E.
