Synchronous belt development background and overview

As early as 1900, synchronous belt drives have been studied and patented many times, but their practical use was after World War II. Because the timing belt is a transmission part that combines the advantages of chains, gears, and triangle tapes, it has been valued with the development of the industry after World War II. It was first developed by the American Unirayal Rubber Company in 1940. In 1946, Singa Company used timing belts for the synchronous transmission of sewing machine needles and bobbins, and achieved significant benefits, and was gradually introduced to other mechanical transmissions. The development and application of synchronous belt drive has been only more than 70 years, but has made rapid progress in all aspects. The synchronous belt transmission is composed of an endless belt with equal-distance teeth on the inner peripheral surface and wheels with corresponding anastomosis. 　　It combines the advantages of belt drive, chain drive and gear drive. When rotating, the power is transmitted through the meshing of the toothed groove of the wheel. Transmission synchronous belt drive has accurate transmission ratio, no slip, can obtain constant speed ratio, stable transmission, can absorb vibration, low noise, large transmission ratio range, generally up to 1:10. 　　Allows linear speeds up to 50M/S, and transfers power from a few watts to hundreds of kilowatts. The transmission efficiency is high, generally up to 98%, the structure is compact, suitable for multi-axis transmission, no lubrication and no pollution, so it can work normally in places where pollution is not allowed and the working environment is harsh. 　　 Transmission products are widely used in various types of mechanical transmission in textile, machine tools, tobacco, communication cables, light industry, chemical industry, metallurgy, instrumentation, food, mining, petroleum, automobile and other industries.
