- Shape and Dimensions: It is usually circular. The outer diameter varies according to the specifications and design requirements of the ribbon weaving machine, generally ranging from dozens to hundreds of millimeters. The thickness of the wheel body also differs based on load-bearing capacity and transmission requirements, commonly ranging from 10mm to 50mm. The inner hole of the synchronous wheel is usually circular for fitting and installation with the drive shaft or other transmission components, and its diameter is determined by the size of the connected shaft.
- Tooth Profile Structure: The tooth profile of the synchronous wheel is a key feature, with common types including trapezoidal teeth and circular arc teeth. The trapezoidal tooth synchronous wheel has trapezoidal-shaped teeth, featuring a simple structure and easy manufacturing. It can transmit a certain amount of torque and is suitable for ribbon weaving machines where the requirement for transmission accuracy is not extremely high. The circular arc tooth synchronous wheel has arc-shaped teeth that mesh more closely with the synchronous belt, offering high transmission accuracy, capable of withstanding large torques, and demonstrating better stability and reliability at high speeds. It is often used in ribbon weaving machines with high requirements for ribbon weaving accuracy.
- Materials: It is generally made of high-strength aluminum alloy, steel, or engineering plastics. The aluminum alloy synchronous wheel is lightweight and has good heat dissipation performance, which can reduce the load of the ribbon weaving machine's transmission system and increase the running speed, but its load-bearing capacity is relatively weak. The steel synchronous wheel is high in strength and wear-resistant, capable of withstanding large torques and impacts, and is suitable for heavy-load and high-speed transmission systems of ribbon weaving machines. The engineering plastic synchronous wheel has good wear resistance, self-lubrication, and shock absorption performance, low noise, and relatively low cost, but its load-bearing capacity and high-temperature resistance are limited, and it is commonly used in some small and low-speed ribbon weaving machines.
The synchronous wheel of the ribbon weaving machine achieves transmission through cooperation with the synchronous belt. The synchronous wheel is installed on the drive shaft or other transmission components of the ribbon weaving machine. When the drive shaft rotates, the synchronous wheel rotates accordingly. The teeth of the synchronous wheel mesh with those of the synchronous belt, precisely transmitting the rotational motion of the drive shaft to the synchronous belt, thereby driving other components of the ribbon weaving machine, such as the let-off mechanism and take-up mechanism, to move synchronously. Since the power transmission between the synchronous wheel and the synchronous belt relies on tooth meshing without relative slippage, it can ensure the accuracy and synchronicity of transmission, guaranteeing the coordinated movement of various components of the ribbon weaving machine, and thus ensuring the quality and production efficiency of the ribbon.
