Surface Textures for Enhanced Seal Lubrication of Tapered Roller Bearings Using LIGA

The Research and Development proposed herein will improve the operating characteristics of traditional rolling-element bearings and the applications to which they contribute through the development and application of MEMS/microstructures in two major categories. First, we will develop low-cost MEMS strain-sensing modules and the means to rapidly bond them to steel and other structures in large quantities. In addition to wire-based solutions, we will also develop modules for wireless data telemetry and power coupling to enable total systems-level solutions for the MEMS sensor modules. This will open the door toward providing low-cost load sensing for many applications. Second, we will explore the use of microstructures to improve heat transfer and lubrication phenomena to decrease friction and improve bearing life.
