Our Capabilities

Selected disciplines behind every Micralink worm gear. A representative but not exhaustive list.

Design

Designing for how the gear actually performs under load, not just on paper.

  • Contact Pattern Management: Leaving-side contact bias preserves the oil entry wedge under load.

  • Tooth Profile Engineering: Optimising the gear tooth profile to prioritise recess action over approach action cuts friction by over 50%, substantially reducing operating heat and gear wear.

Process/ Machine Selection

We match the manufacturing process to your part's application, geometry, volume, and tolerance.

  • Process Selection: Hobbing, thread milling, cold rolling, CNC profile grinding, and machine choice, each selected based on your specific requirements.

  • Manufacturing Flow: The choice of one process affects the rest, with material, heat treatment, and finishing planned together.

Heat Treatment

Precision vacuum carburizing eliminates the surface oxidation inherent to traditional heat treatment, maximizing tooth flank strength and fatigue life.

  • Clean Metallurgy: Low-pressure processing prevents intergranular oxidation and surface contamination.

  • Uniform Case Depth: High-pressure gas quenching ensures consistent hardness across complex tooth geometry with minimal thermal distortion.

Quality Control

Thread profile grinding restores micron-level geometric accuracy to case-hardened worm shafts after heat treatment, delivering quiet operation and extended wear life.

Profile & Pitch Correction: Precision CNC grinding eliminates thermal distortion, correcting lead, pitch, and tooth profile errors for perfect mesh engagement.


Multi-step finishing: achieves low Ra surface finishes for low-friction sliding contact

Secondary Processes

Worm gear sets are tested under operating conditions to verify kinematic accuracy.

  • Critical Applications: Indexing and precision motion-control drives.

  • Common Worm Gear Failure Modes: Worm pitch error, worm wheel runout, assembly misalignment, and contact pattern quality

Applications

Worm gears enable high torque transmission and compact design with significant speed reduction and torque multiplication.
