Background

The mechanical transmission mechanism can change the motion mode, direction or speed provided by power, and is purposefully utilized by people. Ancient transmission mechanisms in China mainly comprise gear transmission, rope belt transmission and chain transmission. In ancient times in China, people tie the earthenware pot with one end of a rope, hold the other end of the rope, rotate and swing the earthenware pot, generate centrifugal force to extrude honey in the earthenware pot, and the early application of the centrifugal separation principle is realized. Modern centrifuges are machines that use centrifugal force to separate components of a mixture of liquid and solid particles or liquid and liquid. The centrifuge is mainly used for separating solid particles from liquid in suspension, or separating two liquids which have different densities and are insoluble with each other in emulsion (for example, cream is separated from milk); it can also be used to remove liquids from wet solids. However, most of the existing centrifuges drive a centrifugal turntable to rotate through a motor, so that the separation efficiency is low, and in addition, if different separation effects are to be achieved, the rotating speed of the motor needs to be adjusted, so that the separation efficiency is further reduced. Therefore, it is necessary to design a gear transmission mechanism for a centrifugal machine to improve the separation efficiency.
