Title: Device for evaluation of the working surface fretting wear characteristics : US 10161840 B2 : United States patent
Extent: 8 lap

Note: Appl. No.: 15/485,230
Abstract: A device for evaluating working surface fretting wear characteristics comprises a bottom holder with a sample secured thereto, springs displacing in the X and Y direction, multilayer piezo elements moving in the X, Y, and Z directions, a housing, a top plate/holder, a linear air bearing housing, a spherical upper sample, a linear air bearing shaft, a three-way force sensor, a moving support of the flat air bearing and the flat air bearing housing, a high frequency generator, an amplifier, a controller, an electrical filter, a computer, a force sensor signal amplifier, and a flat air bearing. Instead of springs, it can comprise additional multilayer piezo elements moving in the X and Y directions. The device performs testing surface wear under conditions nearer to actual fretting wear conditions, continuously observing friction pair condition changes during testing and evaluating wear characteristics of the tested material more accurately
