Product Improvement Program for the M577 Fuze. Volume 1. Redesigned Timer

Abstract

The objective of this project was to redesign the timer gear train components to decrease the manufacturing cost of the M577 fuze. In addition, methods of using the scroll movement as a means of measuring the timer output were investigated. In the proposed design, the ring gear used to transmit the torque from the mainspring was replaced by an external drive gear on the scroll. This change eliminated one part and simplified another. Three of the plates were redesigned as die castings; two of these were combined into one plate.
