Abstract
A flexural pivot is configured as a multi-piece device which is specifically configured to tolerate vibration and shock loading. The flex pivot described uses pre-formed unitary (one-piece) support structures which have integral undercut areas, diametrically opposed slots for flexural member placement and key ways and the like, and near net shape geometry. The flexural members are pre-brazed to facilitate the assembly process. The design of the pre-formed support structures eliminates brazed joints which are common locations of fracture due to vibration and shock loading, resulting in a significantly strengthened pivot. The overall configuration and method described provides an economical flex pivot, whereby the flex pivots are accessible for applications which have not heretofore been feasible.
