Manufacturing Processes & Capabilities

• 4-Stage Modular High-Reduction Gearing: Features a 4-stage gear train achieving an ultra-high 1:1444 reduction ratio within a compact envelope; modular tooling allows flexible gear swapping to tailor overall reduction ratios to application needs.
• Precision Worm & Helical Gear Tooling: The 1st-stage utilizes a precision-molded worm and helical gear pair with tight profile and lead angle tolerances, optimizing tooth contact ratio to eliminate high-speed vibration and gear whine.
• Rigid Housing & Sensor Integration: Engineered to withstand 15–25 kg-cm cable tension and radial loads, the rigid housing incorporates dedicated mounting seats for both VR potentiometers and optical encoder wheels.

Features & Advantages

• Mechanical Self-Locking & Safety: The primary worm-helical stage provides inherent mechanical self-locking, preventing back-driving under user dynamic loads when power is cut off to ensure treadmill incline safety.
• Dual Feedback Versatility: Supports either VR (analog voltage feedback) or optical interrupter wheel (digital pulse feedback) for seamless integration with diverse closed-loop electronic control systems.
• Heavy Torque Capacity & Ultra-Quiet Drive: Handles 15–25 kg-cm output loads smoothly; the combination of helical-worm gearing and self-lubricating polymer gears delivers whisper-quiet, wear-resistant cable actuation.
