The Classification Of Timing Belt

May 17, 2018

    The latest category in the belt is the toothed belt, also known as the synchronous belt.It has the advantages of gear, chain and belt transmission, which has the characteristics of high transmission efficiency, accurate transmission ratio, low noise, energy saving and convenient maintenance.Although its transmission principle had appeared several patents in 1900, it did not begin to industrialize until half a century later, and finally became the dominant transmission product of precision machinery in the 1980s.In particular, the high-precision microstrip made with saturated nitrile rubber and polyurethane elastomer has entered the field of high and new technology.The biggest difference between the toothed belt and the traditional belt is that it is synchronous and silent.Therefore, it is the most respected environmental protection products nowadays.In recent years, the teeth of toothed belt have been changed from fang teeth to round teeth, which further increases the transmission power and the development prospect is very broad.

The timing belt is divided into two types: single - sided and double-sided.The former is mainly used for uniaxial transmission, the later is multi-axis or reverse transmission. Timing belt is a new efficient belt in the world since 1980.The toothed belt is divided into trapezoid and circular arc according to the shape of the tooth, and the torque is the maximum with the synchronous belt of the circular tooth.From the material, tooth belt can be divided into rubber and polyurethane type two kinds, the former and ordinary rubber (usually a neoprene) and special rubber (mostly saturated nitrile rubber).Their structure consists of a strong layer of steel cord or fiberglass and a rubber layer or polyurethane rubber layer formed by rubber and nylon fabric.
