– Gear Metrology Basics

Focuses on verifying gear geometry, performance, and contact conditions.

• Functional gear checking: test the actual meshing behavior of gears in simulated conditions.
  • Double-flank testing: assess composite errors by rotating mating gears under load.
  • Single-flank testing: analyze transmission errors during gear rotation on one side.
• Analytical gear checking: measure individual geometric properties for diagnostic insights.
  • Pitch variation: spacing uniformity between teeth.
  • Profile measurement: shape of gear teeth.
  • Tooth thickness: width of gear teeth at specified locations.
  • Backlash: gap between mating teeth in unloaded condition.
  • Span measurement: width across a specific number of gear teeth.
• Gear surface measurement: evaluate roughness or wear on gear flanks to ensure durability and performance.
