Car rearview mirror adjustment gear

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, Worm-Mated Pinions
• Standard Materials: Automotive-grade high-stiffness POM (Polyoxymethylene / Acetal), Engineering Nylon (PA66 / PA46 / Glass-filled PA), PBT
• Primary Functions: Reduces micro-DC motor speed and multiplies output torque to smoothly drive multi-axis (pitch and roll) mirror viewing angle adjustments
• Applications: Automotive Power Mirror Actuators, Camera Monitor System (CMS) Lens Positioners, Head-Up Display (HUD) Mirror Articulation Units

Manufacturing Processes & Capabilities

• Micro-Module Automotive Tooling: Accommodates M0.2 to M1.5 modules with micro-tolerance tooling; precisely manages mold shrinkage and cooling balance to maintain tight total pitch accuracy, burr-free edges, and strict tooth profiles.
• Strict Concentricity & Runout Control: Maintains micron-level tolerances across the shaft bore, pitch diameter, and step faces on compound gears, ensuring perfect center-distance alignment and non-binding rotation within compact gearbox enclosures.

Features & Advantages

• Smooth Articulation & Low Backlash: High tooth profile accuracy ensures seamless, low-backlash meshing, translating switch inputs into jitter-free, fine-increment mirror adjustments.
• Automotive-Grade Extreme Temperature Stability: Formulated from automotive-grade engineering resins that withstand wide operating temperatures (-40°C to +85°C), maintaining dimensional integrity and impact resistance under continuous stall loads and cyclic reversals.
• Whisper-Quiet, Self-Lubricating & Wear-Resistant: Inherent polymer self-lubrication and vibration-damping properties minimize gear mesh whine and cabin acoustics, ensuring maintenance-free durability over the vehicle's lifespan.
