Patent number: 8381695Abstract: A workpiece has a tribologically useable surface formed as a sliding surface, lubricated by an intermediate material, for a counterpart movable relative to the workpiece in a direction of movement. The sliding surface is provided with a structure formed of a plurality of pockets. The pockets form a closed micropressure chamber delimited by the uninterrupted peripheral rim, respectively. The uninterrupted peripheral rim is a deburred structure edge. In a plan view, the pockets are elongate and have a longitudinal extension. The sliding surface has a functional roughness in the supporting areas between the pockets.Type: GrantFiled: July 9, 2002Date of Patent: February 26, 2013Assignee: Maschinenfabrik Gehring GmbH & Co.Inventors: Ulrich Klink, Gerhard Flores, Tobias Abeln, Oliver Kull

Patent number: 6973367Abstract: In a method for machining bores of workpieces with a desired nominal shape of the bores in operative condition, a bore with a desired nominal shape in inoperative condition is produced in a workpiece and the workpiece is then put in operative condition. A deviation of the desired nominal shape of the bore resulting from the operative conditions is determined. Based on the deviation, an initial shape which shape the bore must have in inoperative condition in order for the bore to assume the desired nominal shape in operative condition is the determined. Bores are then produced by employing the determined initial shape as a template.Type: GrantFiled: August 27, 2004Date of Patent: December 6, 2005Assignee: Maschinenfabrik Gehring GmbH & Co.

Patent number: 6960121Abstract: In a method for honing a bore having first and second sections sequentially arranged in an axial direction of the bore, wherein the first section is hardened so that the first and second sections have different hardness, a honing tool is radially supported by positioning guides of the honing tool on the second bore section. first section is machined with honing stones arranged on the honing tool to remove material from the first section. During machining of the first section, the honing tool is expanded by feeding the honing stones according to a defined feeding mode against a surface of the first section by a force-guided electro-mechanical advancement. During machining of the first section, the working stroke of the honing tool is adjusted continuously at least toward the end of the honing process. Feeding of the guides is realized independently of feeding of the honing stones.Type: GrantFiled: February 18, 2004Date of Patent: November 1, 2005Assignee: Gehring GmbH & Co.

Publication number: 20030120374Abstract: In a method for producing a bore, wherein the bore in an unloaded state has an initial shape and in an operational state has a nominal shape deviating from the initial shape, first a deformation of the bore to a nominal shape present in an operational state is determined. Based on the nominal shape and the deformation determined in the first step, the initial shape is determined. The bore is then transformed by a processing method to the initial shape.Type: ApplicationFiled: December 17, 2002Publication date: June 26, 2003Applicant: Maschinenfabrik Gehring GmbH @$amp; Co.

Patent number: 5630953Abstract: The method of fine-machining a workpiece surface to be supplied with a lubricant during operation of the workpiece includes the steps of subjecting the workpiece surface to a stream of a medium to produce linearly extending channels of a predetermined first depth in the workpiece surface, the linearly extending channels defining areas therebetween, and forming in the areas by subjecting the workpiece surface to a stream of a medium grooves of a second depth smaller than the predetermined first depth. The linearly extending channels may be arranged in a crossed arrangement. Preferably, the method is carried out as a two-step process. Expediently the method further includes the step of employing a laser for at least one of the steps. The laser can form the channels with dimple shaped depressions positioned in a row.Type: GrantFiled: May 13, 1994Date of Patent: May 20, 1997Assignee: Maschinenfabrik Gehring GmbH & Co.Inventor: Ulrich Klink

Patent number: 5441439Abstract: A method for finishing surfaces of workpieces includes a honing process with at least two method steps. In one of the method steps the surface, for example, the inner wall of a bore, is honed to a predetermined final dimension whereby a very fine structure with minimal depth of honing traces is generated so that a great portion of the surface functions as the supporting surface. In a further method step, which can be performed before or after the finishing-honing step, crossed grooves are provided in the surface by subjecting the surface to a stream of a medium, especially a laser, whereby the pattern of the grooves provides a lubricant reservoir for the future use of the workpiece. The treatment with a stream of a medium does not cause deformations at the edges of the grooves. This ensures an optimal distribution of the lubricant.Type: GrantFiled: April 9, 1993Date of Patent: August 15, 1995Assignee: Maschinenfabrik Gehring GmbH & Co.Inventors: Hans Grimm, Walter Lang, Karl-Heinz Bergen, Ernst Lang, Ulrich Klink
