Patent number: 9638244Abstract: A hydrodynamic axial bearing is provided with segments arranged on a circular ring on axial bearings, wherein a plurality of pressure fields are built up. The length of the individual segments is defined in the circumferential direction, between a first edge and a second edge. The first edge delimits the wedge surface of the segments. In fast-rotating bearings, the ratio of segment width to segment length has a decisive influence on the attainable load-bearing capacity and resulting friction losses. The load-bearing capacity and friction losses are improved by increasing the segment length more intensely with increasing radius. The first edge does not run straight but rather has steps, is arcuate or has linear portions with different gradients.Type: GrantFiled: April 29, 2013Date of Patent: May 2, 2017Assignee: BorgWarner Inc.Inventors: Thomas Duecker-Schulz, Thomas Koerner

Patent number: 8312750Abstract: A method for producing a rotationally symmetrical hollow metal part, particularly a shaft. According to the method, bar-shaped ductile solid material is provided, the solid material is heated from about 300° C. below the forging temperature to the forging temperature, the solid material is transversally spline-rolled until weakenings are created in the core zone (3) of the solid material and the sold material is torn open. Two mandrels (5,6) are forcibly introduced into the center of the bar-shaped solid material during the rolling process, and then one mandrel is retracted while the other mandrel continues advancing so as to produce a tubular part. A transversally spline-rolled rotationally symmetrical hollow part, especially a shaft, which is produced according to noted method can be embodied as a transmission shaft, camshaft, drive shaft, output shaft, starter shaft, hollow shaft, or can be a preform for molded parts and the like.Type: GrantFiled: July 5, 2007Date of Patent: November 20, 2012Assignee: Gesenkschmiede Schneider GmbHInventors: Thomas Koerner, Ernst-Peter Schmitz, Peter Kolbe
