Drive Gears for Barcode

Specifications

• Product Category: Precision Transmission Components
• Module Range: M0.2 to M1.5 (Micro to standard module tooling)
• Tooth Profiles: Spur Gears, Helical Gears, Compound Cluster Gears, Stepped Pinion Shaft Gears
• Standard Materials: Wear-resistant Low-Friction POM (Polyoxymethylene / Acetal, e.g., Delrin), Engineering Nylon (PA66 / PA12 / Glass-filled PA)
• Primary Functions: Drives smooth constant-speed paper feed via platen rollers; maintains synchronized constant-tension torque for ribbon supply/take-up spindles
• Applications: Desktop Barcode Printers, Industrial Thermal Transfer Label Printers, Mobile POS Receipt Printers, Healthcare Wristband Printers

Manufacturing Processes & Capabilities

• Micro-Module Tooling & Stepping Precision: Accommodates M0.2 to M1.5 modules using micro-tolerance tooling; strictly regulates total pitch error and tooth profile accuracy to eliminate micro-speed fluctuations under dynamic stepper motor indexing.
• Tight Concentricity & Radial Runout Control: Balanced mold cooling and gating minimize asymmetric shrinkage, maintaining strict concentricity between the shaft bore and pitch diameter for wobble-free platen roller and ribbon shaft rotation.

Features & Advantages

• Constant-Velocity Feeding & Sharp Barcode Resolution: Ultra-smooth tooth engagement delivers stable, jitter-free media advancement, eliminating banding, irregular line widths, and 2D barcode distortions to ensure 100% optical scan accuracy.
• Constant Tension Transfer & Anti-Wrinkle Performance: Precision gear train mechanics deliver smooth torque transmission to ribbon spindles, maintaining balanced winding tension to prevent thermal transfer ribbons from wrinkling, snapping, or skewing.
• Self-Lubricating, Wear-Resistant & Printhead-Safe: Molded from self-lubricating POM and Nylon resins offering low friction and vibration damping; eliminates the need for grease lubrication, preventing oil mist contamination on labels and thermal printheads (TPH).
