Patents by Inventor Jurgen Reingen

Jurgen Reingen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Sliding surface
    Patent number: 9926968
    Abstract: For friction reduction in sliding bearing, it is known to structure the sliding surface (1) by ECM by introducing a plurality of microscopic small indentations (27). According to the invention it is proposed in particular in the same process step to smoothen also the intermediary spaces (6) between the indentations (27), thus to remove the tips of the surface profile.
    Type: Grant
    Filed: August 21, 2014
    Date of Patent: March 27, 2018
    Assignee: MAG IAS GmbH
    Inventors: Leo Schreiber, Jürgen Reingen, Matthias Weber, Wolfgang Hafner, Emanuel Gross, Andreas Grützmacher
  • Structuring of sliding surface portions
    Patent number: 9879726
    Abstract: In order to reduce friction of a crank shaft during operation by a large amount with low complexity through structuring sliding bearing surfaces (1) of the crank shaft through controlled introduction of microscopically small indentations (27) it is proposed for the center bearings and the crank bearings to only structure highly loaded portions of the bearing surface in circumferential direction and also in axial direction since this is already difficult to achieve in view of the operating gap towards the tool that only has a size of a few ?m.

  • SLIDING SURFACE
    Publication number: 20160146251
    Abstract: It is proposed according to the invention for structuring of straight bearing surfaces (1) with microscopically small indentations (27) in particular produced by electro chemical material removal to limit the surface portion of the indentations to 15% to 40% of the entire structured surface since this reduces manufacturing complexity whereas a larger surface portion with indentations (27) hardly generates any further reduction of friction in the straight bearing.
