附录一Knowledge On The Bearings and ShaftThe bearings are fixed and reduce the load coefficient of friction in the process of mechanical transmission components. Can also say that when the other parts on the shaft relative motion, used to reduce the friction coefficient in the process of power transfer and fixed the mechanical parts to maintain the position of the shaft center. Bearings are important parts of modern machinery and equipment. Its main function is to support the mechanical rotating body to reduce the load coefficient of friction of the mechanical equipment in the transmission process. According to the different nature of friction of moving parts, bearings can be divided into two types of rolling bearings and plain bearings.Nano Lake, Italy, found a Roman vessel discovered early instance of ball bearings. The wooden ball bearings are used to support the rotating desktop. Ship construction in 40 BC. It is said that Leonardo da Vinci in the 1500 or so, a ball bearing through description. , There is a very important point is the ball collision, causing additional friction between the ball bearings of all kinds of immature factors. But can put the ball into a small cage to prevent this phenomenon. The 17th century, Galileo fixed ball , or cage ball ball bearings did the earliest description. But then quite a long time, the bearings have been installed on the machine. The first patent on the ball channel the Carmarthen Philip Vaughan in 1794.In 1883, Friedrich Fischer proposed the idea of ??the use of suitable production machine grinding the same size, roundness accurate ball. This laid the foundation to create an independent bearing industry. In 1962, FAG the trademark has been modified and are still used today and become an integral part of the company in 1979.In 1895, Henry Timken designed the first tapered roller bearings, three years later obtained a patent and the establishment of the Timken Company.In 1907, SKF bearing factory Sven temperature Qwest desi
