Description

Technical Field

[0001] The utility model relates to the technical field of stable synchronous belt wheels, and more specifically, to a stable synchronous belt wheel. Background Art

[0002] In the existing technology, the stable synchronous pulley is a key transmission component and is widely used in various mechanical equipment. However, in actual use, the connection between the synchronous pulley and the belt may become loose, which has an adverse effect on the use effect.

[0003] First, when the connection between the stable synchronous pulley and the belt becomes loose, the transmission efficiency will decrease. This is because the loose belt will cause slipping and skidding during the transmission process, thereby reducing the efficiency of energy transmission. In this case, the mechanical equipment may not operate at its best, affecting its performance and stability. In addition, long-term looseness may also cause premature wear of the belt, shorten its service life, and increase maintenance costs.

[0004] Secondly, the looseness of the connection between the synchronous pulley and the belt may also cause noise and vibration problems. When the belt is loose, additional noise and vibration will be generated during the transmission process, which will not only affect the normal operation of the equipment, but may also affect the health of the operator. At the same time, noise and vibration may also interfere with the surrounding environment, especially in places where a quiet environment is required, such as hospitals, schools, etc. Utility Model Content
