With a lot more than 1000 girth gears marketed above the globe CITICIC Gear is a leading provider in the cement and mineral industry&period of time And as member of AGMA &lparAmerican Equipment CZPT rs Association&rpar&comma we do actively get portion in defining the common for gear ranking calculations and services elements&period 
We provide girth gears in a few distinct styles
Fabricated steel
– cast ring
– rolled plate
Cast steel 
Ductile &lparNodular&rpar forged iron  
Fabricated gears grew to become far more typical in the earlier and are built with forged metal gear rim materials and electro welded body structure&period of time The rings are created from a total block of high resistance alloy steel&period of time Following the rough machining of the ring&comma we have out hardening and tempering heat therapy in buy to improve the mechanical characteristic and consequently its pertinent efficiency&period  
Avantages of fabricated girth gears

Lubrication is an important issue to boost the effectiveness of worm gear transmission. The worm gear action generates a lot of warmth, which lowers effectiveness. The electrical power delivered at a presented temperature increases with the transmission performance. Correct lubrication reduces friction and heat, which raises performance.
