Custom Made Casting Steel Large Size Gear Wheel Heavy-Duty Girth Gears
1) Description of Girth Gear
As a principle structural and mechanical component, the girth gear on a rotary drum has widespread effects
when allowed to wear. As a result, gear wear should be addressed immediately, typically through replacement,
though in cases of onset wear, simple adjustments may prevent further damage.
2) Heat Treatment of Girth Gear
Gears are flame or induction hardened to achieve a desirable hardness. Hardness of the girth and pinion
gears plays an essential role in maximizing equipment life.
3) Material of Girth Gear
Castings Steel/ ZG 42CrMo (AISI 4140) or ZG40CrNiMo (AISI 4340)
