XM5 BAROSWITCH ASSEMBLY. PRODUCTION ENGINEERING STUDY
Abstract
The pressure Baroswitch is a stock capsule design of a major pressure capsule manufacturing concern. The capsule involved is made to a ! 0.25% linearity with pressure and a total deflection rate variability of 10%. Capsules meeting these requirements and used in conjunction with the bar linkage compensating mechanism provide satisfactory operating characteristics. The use of stock capsules has provided a major step to increasing the produceability. In addition, the ability of a number of capsule manufacturing concerns to uniformly produce capsules required in this Baroswitch greatly reduced the amount of pre-calibration of selective assembly. Capsule fittings and contacts are fabricated by normal furnace brazing techniques. Element enclosures are accomplished both by induction brazing, and inert atmosphere welding. Standard equipment of this nature plus a few relatively simple fixtures are all that are required. Incorporating a simple linkage design into the gear train has eliminated the need for complicated cam operated differentials. Selective assembly of gears for proper slope correction has been eliminated by a simple variable slide on the lever assembly. (Author)
