Differential Clutch & Safety Gears

Specifications

• Product Category: Precision Transmission & Safety Components
• Module Range: M0.2 to M1.5 (Micro to standard module tooling)
• Assembly Requirement: Must be used and installed in mated pairs (driving and driven pair)
• Standard Materials: Wear-resistant POM (Polyoxymethylene / Acetal), High-toughness Engineering Nylon (PA66 / PA46 / Glass-filled PA)
• Core Functions:
  Differential Clutch Gears: Utilizes a single-tooth differential difference ($\Delta z = 1$) to generate smooth cyclic axial displacement for mechanical engagement, disengagement, or indexing.
  Safety Overload Gears: Features face-cam slip teeth that automatically disengage and slip when load exceeds a preset torque threshold, preventing motor burnout and gear stripping.
• Applications: Medical Device Transmission Protection, Power Tool Torque Limiters, Smart Home Actuators, Vending Machine Dispense Drives, Precision Metering Clutches

Manufacturing Processes & Capabilities

• Differential Tooth Tooling & Micro-Module Precision: Covers M0.2 to M1.5 modules tailored for single-tooth difference designs; micro-tolerance tooling ensures precise pitch circles and tooth thicknesses for non-binding axial displacement.
• Precision Face-Cam Angle Molding: Strictly controls the ramp angle, flank transition, and surface finish of safety slip teeth to deliver repeatable release torque and consistent disengagement under calibrated spring preloads.

Features & Advantages

• Accurate Differential Axial Displacement: Converts continuous rotary motion into precise axial displacement via a single-tooth differential mechanism, eliminating the need for bulky solenoids or complex linkages.
• Reliable Mechanical Overload Protection: Instantly trips and slips during mechanical jams or stall conditions, isolating extreme torque spikes to protect delicate instrument gears and drive motors from catastrophic failure.
• Self-Lubricating, Wear-Resistant & Repeatable Release: Molded from high-grade POM and Nylon resins offering low friction and high fatigue endurance; maintains consistent torque release thresholds even after repeated slip cycles.
