Gear
Failures
Gears can
fail in several different ways. Increased vibration and noise level from the
equipment is commonly associated with gear failures.
Cast irons,
nonferrous alloys, powdered-metals, and steels are materials used in gears.
Some common types of gears are listed below:
|
|
-
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.

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.
