Abstract:

This investigation addresses the imprecision problem exhibited by the Ryder Gear Test ASTM D-1947 presently utilized as a gear lubricant load- carrying capacity qualification test under such specifications as MIL-L-7808 and MIL-L-23699. The primary program objective is to determine the feasibility of developing a precision technique for measuring gear lubricant load-carrying capacity suitable to replace the current costly and imprecise Ryder Gear Test. The revised criteria that has been proposed involves a three step characterization process which includes wear, scoring load, and post scoring recovery time. This criteria will be implemented through a real time monitoring approach. The proposed precision load-carrying capacity test device is a disc on disc approach. Critical precision parameters include continuous loading, test specimen cooling, precision control of specimen quality, and precision control of operating parameters. Utilization of the new criteria in conjunction with the advanced disc on disc machine will provide a cost effective, precision determination of gear lubricant load-carrying capacity. Primary program recommendations include the design, fabrication, and testing of the proposed new test approach.
