Automated Production Lines: Synchronizes multiple stations, such as assembly, sorting, and conveying equipment.
Printing Machinery: Double-sided synchronous drive for rollers, ensuring registration accuracy.
Textile Machinery: Synchronous control for multi-axis winding and coiling equipment.
Advantages and Case Studies
Replaces complex layouts with multiple single-sided belts and pulleys, simplifying the structure.
Achieves multi-axis synchronization through S-shaped or crossed routing (as shown in diagrams).
In printing machines, double-sided timing belt systems eliminate lubrication contamination issues of traditional chain drives.
Selection Considerations
Tooth Profile Matching: Choose arc teeth (HTD) or trapezoidal teeth (T-type) based on load requirements.
Material Selection:
Standard environments: Neoprene (CR),
High-temperature/oil-resistant: Hydrogenated Nitrile Rubber (HNBR)
Clean environments: Polyurethane (PU).
Pulley Design: Must use dedicated double-sided pulleys (e.g., with double-sided flanges).
The core advantage of double-sided timing belts lies in their dual-engagement capability, optimizing transmission layouts in scenarios requiring high space efficiency, precision, or environmental adaptability.
