Synchronous belts are common mechanical automation equipment in the industry. With the continuous development of the mechanical age, there are more and more types of synchronous belts, but many people only know about the types of synchronous belts in polyurethane synchronous belts and rubber synchronous belts. For the above species, we don't know much about other classifications, which is very unfavorable for the use of timing belts. In fact, the synchronous belt can also be subdivided into many types according to the tooth shape. Let me introduce it to you. According to the type of tooth, it can be divided into trapezoidal tooth synchronous belt and arc tooth synchronous belt. Synchronous belts can be divided into single-sided synchronous belts with teeth and double-sided synchronous belts with teeth according to the belt surface. Double-sided synchronous belts are divided into symmetrical synchronous belts (DA type) and staggered synchronous belts (DB type) according to the tooth s…
