초록

Rotary actuators and other mechanical devices incorporating shape memory alloys are provided herein. Shape memory alloys are a group of metals which when deformed at temperatures below their martensite temperatures, resume the shapes which they had prior to the deformation if they are heated to temperatures above their austensite temperatures. Actuators in which shape memory alloys are employed include bias spring types, in which springs deform the shape memory alloy (SMA), and differential actuators, which use two SMA members mechanically connected in s...

청구항

A rotary actuator comprising at least two capstans, each separately mounted on a rotatable shaft supported in a framework, each capstan being capable of rotating the shaft, a shape memory alloy in the form of wire, the shape memory wire being in the form of two separate lengths of wire, one wrapped around each capstan to form a winding, the winding on one capstan being so wrapped that the wire is in a prestretched state, the winding on the other capstan being so wrapped that the wire is in a taut rather than prestretched state, means securing one end of ...
