Description

Technical Field

[0001] The utility model relates to the technical field of synchronous pulleys, in particular to a synchronous pulley with an anti-deviation function. Background Art

[0002] The synchronous pulley set is composed of a closed ring belt with equally spaced teeth on the inner surface and the corresponding pulley. The synchronous pulley is generally made of steel, aluminum alloy, cast iron, brass and other materials. Its inner hole has round hole, D-shaped hole, tapered hole and other forms. The surface treatment includes natural color oxidation, blackening, galvanizing, color zinc plating, high-frequency quenching and other treatments. The accuracy level depends on customer requirements. When synchronously moving, the belt teeth and the tooth grooves of the pulley mesh to transmit motion and power. It is a meshing transmission, so it has various characteristics of gear transmission, chain transmission and flat belt transmission.

[0003] Among them, the prior art authorization announcement number CN220505723U proposes a synchronous pulley with an anti-deviation function, including a synchronous pulley body, a synchronous belt body connected to the outer side of the synchronous pulley body, a limited position assembly fixedly connected to the middle of the synchronous pulley body, the synchronous pulley body including a plurality of V-shaped grooves opened on the outer side thereof, and a fixed block at one end of the synchronous pulley body connected to a toothed shaft step;

[0004] In the prior art, synchronous pulleys are all prevented from deviation by adding retaining edges. This process is simple but will cause a greater degree of wear on the outer side. If the synchronous belt is too loose, the track and gear may be misaligned during rotation, causing the synchronous wheel to deviate. For this reason, we propose a synchronous pulley with an anti-deviation function. Utility Model Content
