Abstract:

A self-starting mechanical timing movement has been redesigned to overcome timing problems that existed in T3019 arming programmers. The redesigned unit, designated XM26, has been subjected to an extensive evaluation program, using 500 production-line movements. Based on this evaluation, the new design is capable of replacing its predecessor, the T3 timing movement. The XM26 is an extremely reliable self-starting movement that delivers 5 oz-in. of useful output torque for the first revolution of its output shaft-a nominal 90 2 sec over its required operating range of -65 to 185F. An analysis of the data obtained with the new unit indicates that a timing tolerance within 90 1 sec is attainable with careful adjustment during fabrication. Specifically detailed in this report are the XM26 test results and their statistical analysis. Also included is a brief summary of the design changes and recommendations for futher design improvements. Author
