Description

Technical Field

[0001] The utility model belongs to the technical field of transmission belts, and in particular relates to an anti-fracture transmission belt. Background Art

[0002] Belt drive uses a tensioned (annular) belt that is put on the pulleys of two transmission shafts. It relies on the friction generated when the belt and pulley are tensioned to transmit the power of one shaft to the other shaft. Belt rotation can be used for long-distance transmission between two shafts (working machine and power machine). Because the belt is elastic, it can alleviate impact, reduce vibration, and transmit smoothly, but it cannot maintain a strict transmission ratio (the ratio of the number of revolutions per minute of the driving wheel to the number of revolutions per minute of the driven wheel). When the transmission parts encounter obstacles or are overloaded, the belt will slip on the pulley, thus preventing damage to the parts. Belt drive is simple and easy to operate, and maintenance is also simple, and it is also easy to disassemble and replace. However, due to the low toughness of the belt, it is easy to break, which in turn increases the maintenance cost of the equipment. Utility Model Content
