pt_101

Specifications

  • Product Category: Precision Transmission Components
  • Module Range: M0.2 to M1.5 (Micro to standard module tooling)
  • Tooth Profiles: Spur Gears, Helical Gears, Cluster/Step Gears, Integrated Pulley-Gear Assemblies
  • 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 translation of optical CIS/CCD carriages; drives ADF rollers for precision paper separation and transport
  • Applications: Flatbed Scanners, High-Speed Document Scanners, Multi-Function Printer (MFP) Scanner Units, Automatic Document Feeders (ADF), Precision Optical Inspection Instruments

Manufacturing Processes & Capabilities

  • Micro-Module Tooling & Profile Precision: Covers M0.2 to M1.5 modules with micron-tolerance tooling; strictly controls total pitch error and tooth profile accuracy to eliminate micro-velocity ripples and ensure ultra-smooth rotational motion.
  • Strict Concentricity & Runout Control: Balanced gating and optimized mold cooling prevent asymmetric shrinkage, maintaining strict concentricity between the mounting bore and pitch diameter to minimize radial runout and mechanical jitter.

Features & Advantages

  • Constant-Speed Transmission & Image Distortion Prevention: Ultra-smooth tooth engagement delivers stable, ripple-free linear carriage translation, eliminating scanning jitter and optical banding artifacts to preserve sharp image resolution.
  • Low Backlash & Precision Paper Feeding: Precise tooth-flank clearances provide repeatable stepping accuracy in ADF paper feed systems, preventing paper skew, multi-sheet feeds, and paper jams.
  • Whisper-Quiet, Self-Lubricating & Optical-Safe: Molded from self-lubricating POM and Nylon formulations that dampen operational resonance for quiet office operation; requires no grease lubrication, preventing oil mist from fogging delicate optical lenses and CIS sensors.
