Investigation of Grease-Lubricated Expendable Spline Connections.

Abstract

The objective of this program was to evaluate the feasibility of three basic arrangements of expendable spline connections, namely, the 'standard,' the 'dogbone,' and the 'muff' splines. Spline wear tests were performed with three SwRI spline wear testers operated under controlled angular misalignment, torque, temperature, and speed conditions, using a MIL-G-81322B grease. Standard, dogbone, and muff spline test specimens of various material and hardness combinations were used, some with varied metallic coatings and designs. The basic objective of this program was accomplished, i.e., to show that the 'expandable spline' concept can be used to advantage to extend the wear life of grease-lubricated steel interface spline connections.
