With much more than a thousand girth gears bought more than the planet CZPT Equipment is a leading provider in the cement and mineral sector. And as member of AGMA (American Gear Makers Association), we do actively just take portion in defining the normal for equipment score calculations and service elements. 
We provide girth gears in 3 diverse designs
Fabricated steel
– cast ring
– rolled plate
Cast steel 
Ductile (Nodular) forged iron  
Fabricated gears grew to become far more typical in the past and are created with solid steel gear rim supplies and electro welded body composition. The rings are produced from a entire block of substantial resistance alloy steel. Following the tough machining of the ring, we carry out hardening and tempering heat treatment in get to improve the mechanical characteristic and for that reason its relevant performance.  
Avantages of fabricated girth gears
The solid materials composition excludes the risk of inclusions
Composition defects like fuel holes, CZPT shrinkage, pin holes, hot tears, sand and slag inclusions are avoided
That’s why, fix welding of the entire body structure and e.g. grinding of toothed locations is not required.
The fabricated producing process excludes the need to have for patterns and risers
Rim content has larger hardness and increased toughness than the content utilized for the underlying framework (i.e. net, gussets)
These characteristics will lessen the lead time and expenses. Fabricated producing ensures a rapidly delivery.
This is specifically useful in an unexpected emergency situation, exactly where the current equipment rim is struggling from damage   
External teeth 
Greatest diameter: 16000 mm 
Toothed confront width: 1700 mm 
Highest module: forty five by hob

Interior teeth 
Greatest Diameter: 6500 mm 
Optimum module: 25.4 
Toothed face width: 400 mm

Tough machining 
Ultrasonic screening and dimensional inspection 
Closing inspection certification

Our girth gears are applied in the cement and minerals industries: 
Various types of horizontal mills 
Rotary dryers 
Rotary kilns 
Any other huge equipment ring application
ZTIC Equipment invested in significant resources and attained many innovations with pinions. The correct blend of material, hardness and ending among pinion and gear is essential for a lengthy life time of the installed tools. We layout and manufacture pinions to match every buyers need, no make a difference how CZPT the scenario may possibly be.

Checks, according JB/T6402-ninety two specifications issued right after acceptance
Down process.
2.2 roughing
Crossed by drawing and keep out allowance, alignment, connection, processing equally within and exterior the circle, combining encounter milling, drilling and other procedures.
two.3 Exploration injuries
Total ultrasonic flaw detection, inside good quality ought to fulfill the 2 requirements of GB7233-87 expectations.
two.4 normalizing pretreatment
Semi-ring pairs normalizing and tempering therapy, provide a very good firm for subsequent surface area hardening press drawings deformation of the 50 % ring equipment inspection following warmth remedy.
2.5 Machining
1st 2 and a 50 % ring is produced with high strength bolts connecting the ring as a total, the all round approach by drawing a circle Quannei Wai tooth and upper and decrease end, and then drawing and machining milling approach demands.
two.6 Elimination of processing stress
The total ring annealed to eradicate stress.
2.7 overall ring surface area hardening
IF along the alveolar tooth surface induction hardening, hardness HRC50 ~ fifty five, efficient hardened layer depth 3 ~ 5mm.
2.8 Last inspection

Specified pitches and prospects of the worm do not allow the worm equipment to drive the worm. This is beneficial when the software needs to lock the output if the software is working in the opposite course. When the helix angle is significantly less than 5°, the worm is self-locking. When the helix angle is higher than 10°, the worm can be driven back again. Worm and worm gear assemblies need to be mounted on vertical, non-intersecting shafts.
