Worm Gear Failure Analysis

Wear, pitting, scoring, overheating, noise, misalignment and contamination for custom worm gear RFQs and design review.

This guide is general engineering context, not a substitute for application-specific calculation, drawing approval or a machine safety assessment.

Wear and polishing

Review lubricant condition, material pairing, sliding speed and contact location.

Scoring and smearing

Investigate overheating, lubricant breakdown, contamination and overload.

Pitting or tooth breakage

Check load calculations, shock events, misalignment, material condition and heat treatment.

Noise and vibration

Inspect runout, bearings, backlash, tooth contact, looseness and damaged shafts.

Overheating

Confirm efficiency assumptions, duty cycle, oil level, cooling, bearing losses and housing ventilation.

Root-cause process

Preserve samples, record operating history, photograph contact patterns and separate symptoms from causes.

Recommended review sequence

  1. Confirm the machine function and operating duty.
  2. Identify the tooth system and installed geometry.
  3. Check load, speed, sliding, temperature and service factor.
  4. Select materials, heat treatment, lubrication and inspection requirements.
  5. Review shafts, bearings, housing, guards and failure consequences.
  6. Issue and approve the final manufacturing drawing.

General context derived from connected worm gear catalogues and current official standards information. Product-specific values must be calculated for the actual design.
