Spur Gear & Worm Shaft for Cameras

Specifications

• Product Category: Precision Transmission Components
• Module Range: M0.2 to M1.5 (Micro to standard module tooling)
• Structural Configuration: One-piece integrally molded spur gear and worm/lead screw shaft
• Standard Materials: Wear-resistant Low-Friction POM (Polyoxymethylene / Acetal), Engineering Nylon (PA66 / PA12 / Glass-filled PA)
• Primary Functions: Transfers motor input torque via integrated spur teeth and drives high-reduction, self-locking angular motion via the worm shaft for pan-tilt rotation
• Applications: Security IP Cameras, PTZ Surveillance Domes, Smart Home Monitoring Cameras, Miniature Optical Zoom/Tilt Mechanisms

Manufacturing Processes & Capabilities

• Integrated Spur & Worm Tooling: Accommodates M0.2 to M1.5 modules utilizing precision multi-cavity tooling; integrally molds the input spur gear and output worm shaft in a single shot with burr-free parting line management.
• Strict Concentricity & Anti-Warpage Control: Balanced gating and optimized packing profiles prevent cooling deflection along the slender worm shaft, maintaining micron-level concentricity among the spur pitch circle, worm axis, and pivot journals to eliminate rotational runout.

Features & Advantages

• One-Piece Compact Integration: Replaces multi-component assemblies (separate gears, metal shafts, and pressed worms) with a single molded part, eliminating assembly tolerances and shaft slippage while optimizing internal space.
• High Reduction Ratio & Mechanical Self-Locking: Slashes rotational speed while amplifying holding torque; features inherent self-locking to maintain stationary camera angles when de-energized, pairing smoothly with stepper micro-stepping.
• Whisper-Quiet, Self-Lubricating & Low Vibration: Sourced from self-lubricating POM and Nylon polymers that dampen stepper motor vibration and resonance, ensuring smooth, silent panning without requiring heavy lubrication.
