•   Worm gears

•   Herringbone gears

•   Helical gears

•   Spur gears

•   Bevel gears

•   Internal gears

Idealistically, gears make contact at points or along lines.  In actual service, gears make contact in small areas or along narrow bands.  Each part of the gear tooth surface is only in contact for a short duration of time.  Gear tooth surface alignment affects the loading in use.  Lubrication and temperature also affect gear teeth as well.

 Gear Failure Analysis

 Some of the failure modes in gears are listed below:

•   Fatigue

•   Wear

•   Stress Rupture

•   Impact

Tooth bending fatigue, contact fatigue, and thermal fatigue are among some of the types of fatigue failures in gears.  Abrasive wear and adhesive wear are the common modes of wear failure of gears.  Material, manufacturing, engineering, service environment, and heat treatment are some of the causes of gear failures.  AMC can provide failure analysis services to determine the cause of your gear failure.
