According to research, the application of chains in our country has a history of more than 3,000 years. In ancient times, the rollover trucks and waterwheels used in rural areas of my country to lift water from low places to high places were similar to modern conveyor chains. In the “Xinyixiangfayao” written by Su Song in the Northern Song Dynasty, it is recorded that what drives the rotation of the armillary sphere is like a chain transmission device made of modern metal. It can be seen that my country is one of the earliest countries in chain application. However, the basic structure of the modern chain was first conceived and proposed by Leonardo da Vinci (1452-1519), the great scientist and artist during the European Renaissance. Since then, in 1832, Galle of France invented the pin chain, and in 1864, the British Slater sleeveless roller chain. But it was the Swiss Hans Renault who truly reached the level of modern chain structure design. In 1880, he improved the shortcomings of the previous chain structure and designed the chain into the popular roller chain today, and obtained the roller chain in the UK. chain invention patent.
