Abstract

A rotary device based on chain transmission and driven by a shape memory effect mainly comprises a driving component, a sprocket shaft component, a shell body component, a chain and the like, and achieves forward and reverse rotation through the shape memory effect of a shape memory polymer driving body in the driving component. The rotary device based on chain transmission and driven by the shape memory effect has the advantages of being simple in structure, easy to control, light in weight, resistant against abrasion, good in shock-absorption effect and the like. All the exposed parts are made of polymer, so that the rotary device based on chain transmission and driven by the shape memory effect can be applied to a high-corrosion environment with strong acid, strong alkali or the like.

Description

technical field [0001] The invention relates to a rotating mechanical device, especially a chain drive rotating device resistant to strong acid and strong alkali corrosion, in particular to a chain drive rotating device made of polymer material capable of resisting strong acid and alkali and driven by shape memory effect device. Background technique [0002] A rotating device is a mechanical component widely used in engineering practice. At present, most rotating devices are driven by traditional driving methods such as electric motors, and most of their components are made of metal. However, the working conditions in engineering practice are very complicated, especially in some special environments such as rotating devices used in highly corrosive conditions such as strong acids and alkalis, which have extremely high requirements for corrosion resistance to environmental media. The main rotating device can no longer meet the requirements of its use. It can be seen that t...
