3000-HP Roller Gear Transmission Development Program. Volume 3. Roller Gear Manufacture

Abstract

This report presents a survey of the manufacturing methods used in the production of the roller gear transmission. The bulk of the material contained herein deals with the roller gear components of the transmission because of the unique manufacturing problems they presented. No attempt is made to describe in detail the more conventional manufacturing processes employed in the program. The most significant aspect of the manufacture of the roller gear components was the extensive use of electron beam welding. This method of assembly was completely satisfactory with respect to holding critical dimensional tolerances; however, weld integrity, particularly in certain highly stressed joints, was a continual problem. Although weld joint design certainly contributed to the problems encountered, the presence of weld voids was certainly a major factor in the weld related fractures.
