Abstract
A cryocooler in which two independently moving flexure systems are split across a single magnetic structure, decreasing package size and increasing resistance to cantilevered mass sag due to external forces. A series of concentrically oriented flexure coupling shafts are provided that allow two independently moving flexure assemblies to be split across a single motor. A series of connectors are included on the forward side of the motor that pass through the outer shaft and allow the inner connecting shaft to be mounted to its flexures without interference. A series of close-out connections are included on the aft flexure stacks that makes assembly possible, providing firm mechanical connections without interference.
