With far more than a thousand girth gears bought above the world CZPT Gear is a leading supplier in the cement and mineral market. And as member of AGMA (American Gear Makers Association), we do actively get element in defining the common for equipment ranking calculations and support aspects. 

We provide girth gears in 3 distinct types

Fabricated steel
– forged ring
– rolled plate

Forged steel 

Ductile (Nodular) solid iron  

Fabricated gears turned a lot more widespread in the previous and are built with forged metal gear rim resources and electro welded body structure. The rings are created from a complete block of higher resistance alloy steel. Soon after the rough machining of the ring, we carry out hardening and tempering warmth remedy in order to improve the mechanical attribute and consequently its pertinent overall performance.  

Avantages of fabricated girth gears

The cast material framework excludes the threat of inclusions

Framework flaws like fuel holes, CZPT shrinkage, pin holes, hot tears, sand and slag inclusions are prevented

Hence, fix welding of the physique construction and e.g. grinding of toothed locations is not needed.

The fabricated production process excludes the require for styles and risers

Rim content has higher hardness and greater strength than the substance utilized for the fundamental construction (i.e. world wide web, gussets)

These features will reduce the lead time and costs. Fabricated manufacturing ensures a quickly delivery.

This is specially helpful in an crisis circumstance, the place the current gear rim is struggling from damage   


Exterior teeth 
Greatest diameter: 16000 mm 
Toothed encounter width: 1700 mm 
Highest module: forty five by hob 
Maximum module: sixty five equipment finishing cutter

Inner teeth 
Highest Diameter: 6500 mm 
Highest module: 25.4 
Toothed confront width: 400 mm

Forging content process 
Final rolling 
Furnace cooling 
Management on production 
Drinking water quenching 
Hardness testing 
Rough machining 
Ultrasonic testing and dimensional inspection 
Final inspection certification

Our girth gears are used in the cement and minerals industries: 
Various kinds of horizontal mills 
Rotary dryers 
Rotary kilns 
Any other huge gear ring software

The complex requirements of a huge CZPT Equipment ring:
1) is pretreated prior to normalizing surface hardening treatment method, the hardness ought to HB210 ~ 250 mechanical overall performance are the greatest energy Rb 690MPa, generate anxiety Rs 490MPa, elongation D5 11%, reduction of region W 25% , effect toughness Ak 30J tooth induction hardened, hardness HRC50 ~ fifty five efficient hardened layer depth 3 ~ 5mm.
2) general ultrasonic flaw detection, internal good quality must meet 2 specifications GB7233-87 normal requirements tooth and fillet magnetic particle inspection, good quality should satisfy 2 demands GB/T9444-88 standards.
three) Notice the casting is not rounded R5 ~ R10.
4) Tooth chamfer at each finishes and 1 45b.5) by 2 and a fifty percent ring equipment tooth width of each and every ring CZPT alongside the edge of a whole ring produced with substantial power bolts, merged with the tooth area need to be at the base heart.
