Description

Technical Field

[0001] The utility model relates to the technical field of synchronous belts, in particular to a synchronous belt adjusting device. Background Art

[0002] The synchronous belt is an endless belt with steel wire rope or glass fiber as the strength layer, covered with polyurethane or chloroprene rubber, and the inner circumference of the belt is made into teeth to mesh with the toothed pulley. When the synchronous belt is driven, the transmission ratio is accurate, the force on the shaft is small, the structure is compact, and it is oil-resistant, wear-resistant, and anti-aging.

[0003] After the synchronous belt is installed on the synchronous pulley, it is necessary to adjust the distance between the two sets of synchronous pulleys to adjust the synchronous belt to a suitable tension, or adjust the synchronous belt front and back to a suitable position. The existing technology uses a tensioning wheel to tension the synchronous belt, and the tensioning force cannot be adjusted in real time, causing inconvenience during use. Utility Model Content
