With more than a thousand girth gears marketed over the globe CZPT Equipment is a leading provider in the cement and mineral market. And as member of AGMA (American Equipment Makers Affiliation), we do actively get portion in defining the regular for gear rating calculations and provider variables. 
We give girth gears in 3 diverse patterns
Fabricated steel
– forged ring
– rolled plate
Solid steel 
Ductile (Nodular) solid iron  
Fabricated gears grew to become a lot more typical in the previous and are constructed with cast steel equipment rim supplies and electro welded physique framework. The rings are produced from a whole block of substantial resistance alloy metal. Following the tough machining of the ring, we carry out hardening and tempering heat treatment method in order to improve the mechanical attribute and consequently its related efficiency.  
Avantages of fabricated girth gears
The forged substance construction excludes the chance of inclusions
Structure flaws like gasoline holes, CZPT shrinkage, pin holes, hot tears, sand and slag inclusions are avoided
That’s why, mend welding of the physique composition and e.g. grinding of toothed places is not necessary.
The fabricated manufacturing process excludes the need for styles and risers
Rim material has higher hardness and larger strength than the material used for the fundamental construction (i.e. net, gussets)
These features will decrease the direct time and expenses. Fabricated producing makes certain a rapidly delivery.
This is especially helpful in an unexpected emergency situation, exactly where the existing equipment rim is suffering from damage   
External teeth 
Optimum diameter: 16000 mm 
Toothed face width: 1700 mm 
Maximum module: forty five by hob 
Maximum module: sixty five gear finishing cutter
Inner teeth 
Optimum Diameter: 6500 mm 
Optimum module: 25.4 
Toothed encounter width: 400 mm
Forging content process 
Ultimate rolling 
Furnace cooling 
Manage on production 
H2o quenching 
Hardness testing 
Rough machining 
Ultrasonic testing and dimensional inspection 
Final inspection certification

Our pinions are utilized in the cement and minerals industries:
Ball – mills
ROD – mills
Semi Autogeneous Grind (SAG)
Rotary kilns/coolers/dryers
One Supply

The technical requirements of a massive CZPT Equipment ring:
one) is pretreated just before normalizing floor hardening remedy, the hardness need to HB210 ~ 250 mechanical functionality are the final energy Rb 690MPa, yield tension Rs 490MPa, elongation D5 eleven%, reduction of area W twenty five% , effect toughness Ak 30J tooth induction hardened, hardness HRC50 ~ 55 efficient hardened layer depth 3 ~ 5mm.
two) total ultrasonic flaw detection, inside good quality should fulfill 2 requirements GB7233-87 common specifications tooth and fillet magnetic particle inspection, good quality must fulfill 2 needs GB/T9444-88 standards.
three) Observe the casting is not rounded R5 ~ R10.
four) Tooth chamfer at each ends and 1 45b.5) by 2 and a half ring equipment tooth width of each and every ring CZPT along the edge of a total ring produced with substantial energy bolts, combined with the tooth floor need to be at the base heart.
two massive ring equipment manufacturing method
2.1 of tough
Metal casting blank is offered by CITIC Heavy CZPT Co., Ltd. Weighty Forging plant, operate by GB11352-89 standard specifies specifications for modeling in accordance to the casting method, smelting, casting, strike boxes, cleaning, dressing castings. For the duration of inspection and acceptance by the drawings and Technical needs for steel blank
Checks, in accordance JB/T6402-92 requirements issued after acceptance
Down treatment.
2.2 roughing
Crossed by drawing and keep out allowance, alignment, link, processing both inside of and exterior the circle, combining face milling, drilling and other processes.
two.3 Exploration injury
Overall ultrasonic flaw detection, interior top quality need to satisfy the 2 specifications of GB7233-87 expectations.
two.4 normalizing pretreatment
Semi-ring pairs normalizing and tempering treatment method, offer a good group for subsequent area hardening press drawings deformation of the half ring equipment inspection soon after heat remedy.
2.5 Machining
Initial 2 and a half ring is manufactured with high energy bolts connecting the ring as a complete, the overall method by drawing a circle Quannei Wai teeth and higher and lower end, and then drawing and machining milling method specifications.
2.6 Elimination of processing pressure
The overall ring annealed to get rid of tension.
two.7 overall ring area hardening
IF along the alveolar tooth floor induction hardening, hardness HRC50 ~ fifty five, successful hardened layer depth 3 ~ 5mm.
2.8 Ultimate inspection
First, the detection frequency quenching, the hardness soon after tempering ring equipment cogging satisfies the requirements of the drawings next, to detect regardless of whether the greatest outer diameter more substantial dimension D6944 as the deformation 3mm, the mechanical correction essential until experienced Thirdly, tooth and fillet magnetic particle inspection, quality should meet 2 needs GB/T9444-88 standard needs Finally, in accordance to the drawings and technical specifications for ultimate inspection.
