With a lot more than a thousand girth gears offered more than the world CZPT Equipment is a leading supplier in the cement and mineral sector. And as member of AGMA (American Gear Makers Association), we do actively take portion in defining the normal for equipment rating calculations and provider variables. 
We offer girth gears in 3 different patterns
Fabricated steel
– cast ring
– rolled plate
Solid steel 
Ductile (Nodular) forged iron  
Fabricated gears became a lot more typical in the past and are constructed with solid steel gear rim materials and electro welded human body construction. The rings are made from a whole block of substantial resistance alloy steel. After the tough machining of the ring, we carry out hardening and tempering heat remedy in buy to enhance the mechanical attribute and for that reason its appropriate functionality.  
Avantages of fabricated girth gears
The forged substance structure excludes the danger of inclusions
Composition problems like gas holes, CZPT shrinkage, pin holes, hot tears, sand and slag inclusions are prevented
Consequently, fix welding of the body framework and e.g. grinding of toothed places is not necessary.
The fabricated manufacturing procedure excludes the need for patterns and risers
Rim materials has larger hardness and increased toughness than the substance utilized for the fundamental construction (i.e. internet, gussets)
These functions will reduce the direct time and expenses. Fabricated production makes certain a quick delivery.
This is specially useful in an crisis predicament, where the current equipment rim is struggling from damage   
External teeth 
Maximum diameter: 16000 mm 
Toothed confront width: 1700 mm 
Optimum module: forty five by hob 
Maximum module: sixty five gear finishing cutter
Inside teeth 
Maximum Diameter: 6500 mm 
Highest module: 25.4 
Toothed face width: four hundred mm
Forging materials process 
Ultimate rolling 
Furnace cooling 
Management on production 
Drinking water quenching 
Hardness testing 
Tough machining 
Ultrasonic tests and dimensional inspection 
Ultimate inspection certification

Our girth gears are utilized in the cement and minerals industries: 
Various varieties of horizontal mills 
Rotary dryers 
Rotary kilns 
Any other massive gear ring application
ZTIC Gear invested in significant sources and reached several improvements with pinions. The right combination of content, hardness and ending between pinion and gear is vital for a lengthy life span of the installed gear. We style and manufacture pinions to match each clients want, no matter how CZPT the situation might be. 

Pinion design
reliable on shaft / integral
self aligned
spur, helical or double helical
forged alloyed steel
via hardened, case hardened or quenched and tempered
Spur, helical or double helical
gear slicing with hobs
the gear high quality is checked by profile tester
tooth flank modification
– profile correction 
– direct correction (straight/barrel)
types /ratios in accordance to ISO-DIN-A.G.M.A.
FEM/FEA simulation software program
Our pinions are used in the cement and minerals industries:
Ball – mills
ROD – mills
Semi Autogeneous Grind (SAG)
Rotary kilns/coolers/dryers

two) total ultrasonic flaw detection, inner quality must meet 2 demands GB7233-87 standard needs tooth and fillet magnetic particle inspection, high quality must fulfill 2 needs GB/T9444-88 expectations.
three) Observe the casting is not rounded R5 ~ R10.
4) Tooth chamfer at the two finishes and 1 45b.5) by 2 and a half ring equipment tooth width of every single ring CZPT alongside the edge of a total ring manufactured with high strength bolts, merged with the tooth floor have to be at the bottom heart.
2 big ring equipment manufacturing procedure
two.1 of rough
Metal casting blank is offered by CITIC Hefty CZPT Co., Ltd. Hefty Forging plant, run by GB11352-89 normal specifies demands for modeling according to the casting approach, smelting, casting, hit bins, cleansing, dressing castings. In the course of inspection and acceptance by the drawings and Technical specifications for metal blank
Checks, in accordance JB/T6402-ninety two expectations issued soon after acceptance
Down method.
two.2 roughing
Crossed by drawing and continue to be out allowance, alignment, relationship, processing the two inside of and outside the circle, combining confront milling, drilling and other processes.
two.3 Exploration damage
Overall ultrasonic flaw detection, inner high quality ought to meet up with the 2 needs of GB7233-87 requirements.
two.4 normalizing pretreatment
Semi-ring pairs normalizing and tempering treatment, offer a great organization for subsequent surface area hardening push drawings deformation of the fifty percent ring gear inspection following heat remedy.
2.5 Machining
Initial 2 and a half ring is created with high energy bolts connecting the ring as a complete, the general procedure by drawing a circle Quannei Wai tooth and higher and reduced stop, and then drawing and machining milling method specifications.
two.6 Elimination of processing anxiety
The general ring annealed to eliminate stress.
two.7 all round ring area hardening
IF together the alveolar tooth surface area induction hardening, hardness HRC50 ~ 55, effective hardened layer depth 3 ~ 5mm.
2.8 Final inspection
Very first, the detection frequency quenching, the hardness right after tempering ring equipment cogging satisfies the specifications of the drawings next, to detect whether or not the maximum outer diameter larger size D6944 as the deformation 3mm, the mechanical correction necessary until experienced Thirdly, tooth and fillet magnetic particle inspection, quality ought to meet up with 2 requirements GB/T9444-88 common specifications Finally, according to the drawings and technical specifications for closing inspection.

Lubrication is an important element to increase the performance of worm gear transmission. The worm equipment motion generates a great deal of heat, which decreases efficiency. The electrical power sent at a presented temperature raises with the transmission performance. Suitable lubrication minimizes friction and heat, which will increase efficiency.
