With a lot more than a thousand girth gears sold above the world CZPT Equipment is a leading supplier in the cement and mineral market. And as member of AGMA &lparAmerican Equipment Makers Association), we do actively get element in defining the normal for gear score calculations and services variables. 
We provide girth gears in 3 diverse patterns
Fabricated steel
– forged ring
– rolled plate
Forged steel 
Ductile &lparNodular) forged iron  
Fabricated gears became more common in the past and are made with cast metal equipment rim supplies and electro welded body structure. The rings are manufactured from a complete block of higher resistance alloy steel. Right after the rough machining of the ring, we carry out hardening and tempering warmth treatment in order to boost the mechanical characteristic and therefore its appropriate performance.  
Avantages of fabricated girth gears
The solid materials structure excludes the danger of inclusions
Structure flaws like fuel holes, CZPT shrinkage, pin holes, sizzling tears, sand and slag inclusions are prevented
That’s why, fix welding of the physique composition and e.g. grinding of toothed places is not needed.
The fabricated producing process excludes the need to have for patterns and risers
Rim substance has larger hardness and greater toughness than the substance utilised for the underlying structure &lpari.e. net, gussets)
These functions will reduce the guide time and charges. Fabricated manufacturing makes certain a quickly shipping.
This is specifically advantageous in an crisis situation, the place the existing gear rim is struggling from damage   
External teeth 
Greatest diameter: 16000 mm 
Toothed encounter width: 1700 mm 
Optimum module: 45 by hob 
Greatest module: sixty five gear finishing cutter
Interior teeth 
Greatest Diameter: 6500 mm 
Optimum module: 25.4 
Toothed experience width: four hundred mm
Forging material process 
Closing rolling 
Furnace cooling 
Management on production 
H2o quenching 
Hardness testing 
Tough machining 
Ultrasonic tests and dimensional inspection 
Last inspection certification

Our girth gears are applied in the cement and minerals industries: 
Numerous sorts of horizontal mills 
Rotary dryers 
Rotary kilns 
Any other big gear ring software
ZTIC Equipment invested in significant resources and attained many improvements with pinions. The right blend of content, hardness and ending amongst pinion and gear is critical for a prolonged life span of the mounted gear. We design and style and manufacture pinions to match every single consumers need, no issue how CZPT the scenario may possibly be.

The performance of a worm equipment transmission is dependent to a huge extent on the helix angle of the worm. Multi-threaded worms and gears with higher helix angles have established to be twenty five% to 50% more successful than solitary-threaded worms. The sliding action of the worm meshing with or meshing with the worm equipment benefits in considerable friction and reduction of performance compared to other sorts of gears. Boost performance with hardened and ground worm switch bronze worm gears.
