V-belt transmission operates on the principle of friction between the belt and pulleys. When the prime mover, such as an electric motor, turns the driving pulley, the belt rotates around it. Due to the wedge shape of the V-belt, a significant amount of friction is generated, allowing the belt to transmit power to the driven pulley. This system can effectively transfer rotational motion from one axis to another, making it invaluable in various mechanical setups.

  • The fundamental structure of HEC begins with cellulose, which consists of a linear chain of glucose units linked by β-1,4-glycosidic bonds. In the case of HEC, hydroxyethyl groups (-O-CH2-CH2-OH) are introduced into the cellulose structure through a process known as etherification. The degree of substitution, which reflects the average number of hydroxyethyl groups replaced per glucose unit, plays a critical role in determining the properties of HEC.
