Precision Anti-Backlash Gears

Specifications

• Product Category: Precision Transmission Components
• Tooth Profiles: Anti-Backlash Spur / Helical configurations
• Module Range: M0.2 to M1.5 (Micro to standard module tooling)
• Standard Materials: Wear-resistant POM (Polyoxymethylene / Acetal), Engineering Nylon (PA66 / PA46 / Glass-filled PA)
• Mechanism Structure: Scissor-type dual-gear spring-loaded elastic compensation
• Primary Function: Eliminates backlash and lost motion during forward/reverse rotational cycling
• Applications: Security IP Camera Pan-Tilt Swivel Bases, Optical Lens Focus Drives, Micro Robotic Joints, Precision Medical Actuators

Manufacturing Processes & Capabilities

• Micro-Module Dual-Gear Tooling: Covers M0.2 to M1.5 modules for both spur and helical profiles; micro-tolerance tooling ensures strict tooth profile consistency, pitch-circle concentricity, and minimal face runout between primary and secondary gear plates.
• Integrated Spring Retainer & Guide Track Molding: Accurately forms internal torsion/extension spring retaining posts and rotational guide tracks, maintaining uniform elastic preload and smooth relative displacement without binding.

Features & Advantages

• Zero Backlash & Lost Motion Elimination: Spring preload forces the floating gear to take up meshing clearances on both tooth flanks, eliminating lost motion and preventing video jitter or angle drift during camera reversal.
• Automatic Wear Compensation: The elastic spring mechanism automatically takes up tooth flank wear over time, continuously maintaining zero-clearance engagement and extending long-term positioning accuracy.
• Quiet Operation, Self-Lubrication & Maintenance-Free: Molded from self-lubricating POM and Nylon to absorb reversal impact shocks and gear chatter, ensuring whisper-quiet, grease-free reliability in continuous scanning applications.
