Precision Dual Helical Gear for Printers

Specifications

• Product Category: Precision Transmission Components
• Material: DuPont Delrin® 500P (General-purpose high-viscosity POM / Acetal)
• Module: M0.7
• Tooth Configuration: Dual Helical Gear (24T LH + 52T RH)
• Helix Hand: Left-Hand (LH) + Right-Hand (RH) Compound Combination
• Applications: Inkjet Printers, Laser Printers, Multi-Function Printers (MFPs), Digital Copiers (Paper Feed, Transport Rollers, Toner Cartridge Drivetrains)

Manufacturing Processes & Capabilities

• Compound Dual-Helix Gear Tooling: Molded with high-precision tooling that integrates 24T (LH) and 52T (RH) M0.7 helical profiles onto a single component; strictly controls helix angle symmetry, concentricity, and axial runout for seamless meshing.
• DuPont Delrin® 500P Process Optimization: Tailored molding parameters accommodate the crystallization characteristics of Delrin 500P, eliminating differential shrinkage and internal stress to ensure tight dimensional stability, high stiffness, and strict roundness.

Features & Advantages

• Axial Thrust Balancing & Smooth Paper Feeding: Opposing left- and right-hand helical gears balance and neutralize meshing axial thrust forces, reducing shaft bearing strain to deliver steady, jitter-free paper transport and prevent paper jams.
• High Contact Ratio & Whisper-Quiet Transmission: Progressive tooth engagement combined with precision M0.7 geometry increases contact ratio, eliminating gear whine to meet strict acoustic standards for office environments.
• Superior Wear Resistance & Self-Lubricating Longevity: Delrin 500P provides low friction, high mechanical strength, and fatigue endurance for maintenance-free operation without grease lubrication, preventing paper or internal component contamination.
