Synchronous belt development background
Synchronous belt drive has been researched and patented many times in 1900, but its practical use is after the Second World War. Since the timing belt is a transmission part that combines the advantages of chain, gear and triangular tape, it was paid attention to with the development of the post-World War II industry. It was first developed by Unirayal Rubber Company in 1940. In 1946, Singa used the timing belt on the synchronous drive of the sewing machine needle and the bobbin, which achieved significant benefits and was gradually introduced to other mechanical transmissions. The development and application of timing belt transmission has only been more than 70 years, but it has made rapid progress in various aspects.
