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 series. Another type uses concentric cylindrical members. One member is in the form of a sleeve surrounding a cylinder, both being constructed of shape memory alloys. Herein two capstans are mounted on a shaft which is supported in a framework. Each capstan is capable of rotating the shaft. Shape memory wire, as two separate lengths of wire, is wrapped around each capstan to form a winding around that capstan. The winding on one capstan is so wrapped that the wire is in a prestretched state. The winding on the other capstan is so wrapped that the wire is in a taut, but not a prestretched state. Heating one performs work in one direction, thus deforming the other one. When the other SMA is heated the action is reversed.

대표청구항 ▼

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 each winding to its capstan, means securing the other end of each winding to the framework, the ends being so secured that the capstans are oppositely wound, means for separately heating each set of windings, means for selectively activating each heating means alternately to heat the windings to effect a martensitic phase transformation conferring terminal forces on the wire lengths and angular moments of force on capstans to rotate partially the capstans and the drive shaft connected thereto.
