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, in particular to a chain drive rotation device resistant to strong acid and alkali corrosion, in particular to a chain drive rotation device that is made of polymer material and is resistant to strong acid and alkali and is driven by a shape memory effect. Device. Background technique [0002] Rotating device is a mechanical part 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 require extremely high resistance to corrosion by environmental media. The existing metal materials are used as The main rotating device can no longer meet its requirements. I...
