Abstract

The invention discloses a hydrogel-based low-temperature control transmission device. The hydrogel-based low-temperature control transmission device comprises an input end used for inputting power, an output end used for outputting power, and a low-temperature control transmission part used for transmitting the input end and the output end, wherein the low-temperature control transmission part comprises a closed box, a driving shaft and a driven shaft, wherein hydrogel is held in the closed box, is in a liquid state at a high temperature, and is in a solid state at a low temperature; one end of the driving shaft is inserted into the closed box and is coated with the hydrogel; the other end of the driving shaft is connected with the input end; one end of the driven shaft is inserted into the closed box and is coated with the hydrogel; the other end of the driven shaft is connected with the output end; the driving shaft and the driven shaft are arranged coaxially. The speed-variable transmission output of the transmission device is realized automatically by sensing the change of the ambient temperature out of the transmission device by utilizing the thermal reversible hydrogel, so that highly intelligent control is realized; moreover, the hydrogel-based low-temperature control transmission device has high biological compatibility, and can be implanted into an animal to serve as an intelligent speed-variable transmission device and a protection device.

Description

technical field [0001] The present invention relates to a transmission, and more particularly to a hydrogel-based low temperature control transmission. Background technique [0002] The transmission device is an intermediate device that transmits the power of the power device to the working mechanism, etc. The transmission device can be seen in many places. The transmission device plays an important role in the power transmission process. For example, cars that drive on the road every day, The transmission device is an indispensable part in the running of the car. The power from the engine is transmitted to the driving wheels of the car through the transmission device to generate driving force so that the car can run on the road at a certain speed. [0003] In daily life, common transmission devices include mechanical transmission, hydraulic transmission, hydraulic transmission, electric transmission and so on. Mechanical transmission is widely used in mechanical engineerin...
