With a lot more than 1000 girth gears sold more than the planet CZPT Equipment is a leading provider in the cement and mineral sector. And as member of AGMA (American Gear Producers Affiliation), we do actively consider part in defining the regular for gear ranking calculations and services variables. 
We offer girth gears in 3 various styles
Fabricated steel
– forged ring
– rolled plate
Forged steel 
Ductile (Nodular) cast iron  
Fabricated gears turned much more typical in the past and are built with cast metal equipment rim supplies and electro welded entire body composition. The rings are produced from a total block of high resistance alloy metal. Soon after the tough machining of the ring, we carry out hardening and tempering warmth remedy in purchase to improve the mechanical attribute and for that reason its appropriate overall performance.  
Avantages of fabricated girth gears
The solid materials framework excludes the danger of inclusions
Composition defects like gas holes, CZPT shrinkage, pin holes, scorching tears, sand and slag inclusions are avoided
That’s why, mend welding of the entire body framework and e.g. grinding of toothed locations is not needed.
The fabricated production method excludes the need to have for patterns and risers
Rim materials has higher hardness and larger strength than the material utilized for the fundamental composition (i.e. world wide web, gussets)
These functions will minimize the lead time and charges. Fabricated manufacturing makes certain a fast delivery.
This is specifically advantageous in an crisis predicament, the place the current gear rim is suffering from damage   
Exterior teeth

Our girth gears are used in the cement and minerals industries: 
A variety of kinds of horizontal mills 
Rotary dryers 
Rotary kilns 
Any other big gear ring software
ZTIC Gear invested in significant methods and reached several innovations with pinions. The correct blend of materials, hardness and ending amongst pinion and equipment is vital for a lengthy life span of the mounted products. We design and manufacture pinions to match each consumers want, no make a difference how CZPT the situation might be.

The specialized needs of a massive CZPT Gear ring:
one) is pretreated prior to normalizing surface hardening therapy, the hardness must HB210 ~ 250 mechanical efficiency are the supreme toughness Rb 690MPa, produce pressure Rs 490MPa, elongation D5 11%, reduction of spot W 25% , effect toughness Ak 30J enamel induction hardened, hardness HRC50 ~ fifty five successful hardened layer depth 3 ~ 5mm.
2) total ultrasonic flaw detection, internal top quality need to meet 2 specifications GB7233-87 common needs tooth and fillet magnetic particle inspection, good quality ought to satisfy 2 demands GB/T9444-88 requirements.
3) Be aware the casting is not rounded R5 ~ R10.
4) Tooth chamfer at both finishes and 1 45b.5) by 2 and a half ring gear tooth width of every single ring CZPT together the edge of a entire ring manufactured with large energy bolts, blended with the tooth surface need to be at the bottom center.
2 big ring gear producing method
2.1 of tough
Steel casting blank is provided by CITIC Hefty CZPT Co., Ltd. Heavy Forging plant, run by GB11352-89 standard specifies specifications for modeling according to the casting method, smelting, casting, strike boxes, cleaning, dressing castings. During inspection and acceptance by the drawings and Technical requirements for steel blank
Checks, in accordance JB/T6402-92 requirements issued following acceptance
Down method.
2.2 roughing
Crossed by drawing and stay out allowance, alignment, relationship, processing both inside and outside the house the circle, combining encounter milling, drilling and other procedures.
two.3 Exploration harm
Total ultrasonic flaw detection, internal top quality must fulfill the 2 specifications of GB7233-87 expectations.
two.4 normalizing pretreatment
Semi-ring pairs normalizing and tempering remedy, offer a good business for subsequent surface area hardening press drawings deformation of the 50 percent ring equipment inspection following heat treatment.
two.5 Machining
Very first 2 and a half ring is created with higher strength bolts connecting the ring as a total, the total approach by drawing a circle Quannei Wai enamel and higher and reduce stop, and then drawing and machining milling procedure needs.
two.6 Elimination of processing anxiety
The total ring annealed to eradicate tension.
2.7 all round ring floor hardening
IF along the alveolar tooth area induction hardening, hardness HRC50 ~ 55, powerful hardened layer depth 3 ~ 5mm.
2.8 Final inspection
1st, the detection frequency quenching, the hardness after tempering ring gear cogging satisfies the demands of the drawings secondly, to detect regardless of whether the highest outer diameter more substantial dimensions D6944 as the deformation 3mm, the mechanical correction essential until experienced Thirdly, tooth and fillet magnetic particle inspection, top quality must fulfill 2 specifications GB/T9444-88 standard specifications Last but not least, in accordance to the drawings and specialized requirements for final inspection.

The equipment ratio of the worm equipment set is determined by dividing the number of enamel of the gear by the number of threads. Consequently, solitary thread yields higher ratios than multithreading. All ep worm gear bushings have left or proper thread. ep worm gear sets are offered in single, double, triple and quadruple threads.
