When tightening the synchronous belt, some of the existing ones do not have a tensioning pulley, and some with tensioning pulleys are all fixed. After being used for a period of time, due to the extensibility of the rubber, it is easy to become loose, resulting in the synchronous belt slipping. However, if it is installed too tightly, it is easy to shorten the service life of the synchronous belt, increase the running resistance, and cause phenomena such as tooth dropout, bringing potential hazards to production and quality.
