Abstract

The invention discloses a shape memory alloy thermal machine driving device and belongs to the technical field of electromechanical equipment. The shape memory alloy thermal machine driving device comprises shape memory alloy thermal machines mounted on a base plate. The shape memory alloy thermal machines are connected with belt transmission mechanisms through movable pulley mechanisms; the belttransmission mechanisms are connected with spindles through one-way bearings, and the other ends of the spindles are connected with vertical bearing seats; and the shape memory alloy thermal machinesare connected with a thermal machine control system. The shape memory alloy thermal machine driving device has the beneficial effects that the advantages of simple mechanical structure, large output displacement and the like are achieved; by additionally arranging the movable pulley mechanisms, the output displacement of shape memory alloy springs is enlarged by nearly two times, and by additionally arranging the belt transmission mechanisms, driving performance can be improved easily; and a new design scheme is provided for a shape memory alloy thermal machine driver.

Description

technical field [0001] The invention relates to a heat engine driven by a shape memory alloy, which belongs to the technical field of electromechanical equipment. Background technique [0002] Shape memory alloy is a new type of functional metal material. It was produced in the early 1960s and is currently widely used in many fields including electromechanical, aerospace, medical equipment, and automobiles. Shape memory alloys have excellent shape memory effects, can change shape through reasonable heating and control, and output large displacement and driving force, so they can be made into drives and used in the field of intelligent robots. The SMA spring made according to the one-way shape memory effect of the shape memory alloy is an important part of the heat engine and the fundamental source of the heat engine's driving force. It can achieve the effect of the two-way shape memory alloy with a common spring with a certain stiffness coefficient. And the output displacem...
