Description

Technical Field

[0001] The utility model relates to the field of double-sided synchronous belts, in particular to a high-strength double-sided staggered tooth synchronous belt. Background Art

[0002] Synchronous toothed belt is abbreviated as synchronous belt, also known as timing belt. It is similar to common belt transmission methods such as V-belt and flat belt, and is a flexible transmission form. The synchronous toothed belt meshes with the toothed pulley. There is no relative sliding between the toothed belt and the pulley, thus ensuring synchronous transmission and constant transmission ratio. The working surface of the synchronous toothed belt and the flange surface of the pulley are made into corresponding tooth shapes, and the belt is meshed with them for belt transmission. Double-sided toothed synchronous belt is mainly used for double-sided transmission, and has the characteristics of synchronization, simultaneity and double efficiency. Double-sided toothed synchronous belt can be divided into two standard types according to the non-layout of the belt teeth: DA type double-sided toothed synchronous belt, the belt teeth on both sides are arranged symmetrically. DB type double-sided toothed synchronous belt, the belt teeth on both sides are arranged in staggered positions.
