Deliver Enquiry

With more than 1000 girth gears marketed above the world CZPT Equipment is a leading provider in the cement and mineral business. And as member of AGMA (American Equipment Producers Affiliation), we do actively take portion in defining the standard for equipment score calculations and provider elements. 

We provide girth gears in 3 diverse designs

Fabricated steel
– cast ring
– rolled plate

Cast steel 

Ductile (Nodular) solid iron  

Fabricated gears became more widespread in the previous and are constructed with cast steel equipment rim materials and electro welded body framework. The rings are produced from a entire block of higher resistance alloy metal. Right after the tough machining of the ring, we have out hardening and tempering warmth treatment in purchase to increase the mechanical characteristic and for that reason its relevant functionality.  

Avantages of fabricated girth gears

The solid content structure excludes the chance of inclusions

Framework problems like gasoline holes, CZPT shrinkage, pin holes, sizzling tears, sand and slag inclusions are prevented

That’s why, mend welding of the physique construction and e.g. grinding of toothed regions is not essential.

The fabricated production treatment excludes the require for designs and risers

Rim material has larger hardness and larger toughness than the substance used for the underlying structure (i.e. net, gussets)

These attributes will minimize the guide time and charges. Fabricated producing ensures a quick delivery.

This is specially useful in an emergency circumstance, the place the current gear rim is struggling from damage   


Exterior teeth 
Highest diameter: 16000 mm 
Toothed experience width: 1700 mm 
Optimum module: 45 by hob 
Highest module: 65 equipment finishing cutter

Inside teeth 
Highest Diameter: 6500 mm 
Greatest module: twenty five.4 
Toothed encounter width: 400 mm

Forging materials process

Ultrasonic testing and dimensional inspection 
Last inspection certification

Our girth gears are applied in the cement and minerals industries: 
A variety of kinds of horizontal mills 
Rotary dryers 
Rotary kilns 
Any other massive equipment ring software

The specialized requirements of a large CZPT Equipment ring:
1) is pretreated before normalizing area hardening therapy, the hardness should HB210 ~ 250 mechanical efficiency are the final energy Rb 690MPa, yield tension Rs 490MPa, elongation D5 11%, reduction of region W 25% , effect toughness Ak 30J tooth induction hardened, hardness HRC50 ~ 55 efficient hardened layer depth 3 ~ 5mm.
two) total ultrasonic flaw detection, internal quality should meet 2 demands GB7233-87 standard specifications tooth and fillet magnetic particle inspection, top quality should meet up with 2 requirements GB/T9444-88 requirements.
3) Be aware the casting is not rounded R5 ~ R10.
four) Tooth chamfer at both finishes and 1 45b.5) by 2 and a 50 % ring gear tooth width of every ring CZPT alongside the edge of a entire ring manufactured with substantial power bolts, merged with the tooth surface area need to be at the base centre.
2 huge ring equipment manufacturing procedure
two.1 of rough
Metal casting blank is offered by CITIC Hefty CZPT Co., Ltd. Heavy Forging plant, operate by GB11352-89 regular specifies demands for modeling in accordance to the casting process, smelting, casting, hit boxes, cleansing, dressing castings. For the duration of inspection and acceptance by the drawings and Technical needs for metal blank

Down method.
2.2 roughing
Crossed by drawing and stay out allowance, alignment, connection, processing each within and outside the circle, combining experience milling, drilling and other processes.
two.3 Exploration damage
Total ultrasonic flaw detection, inner top quality ought to meet the 2 needs of GB7233-87 standards.
2.4 normalizing pretreatment
Semi-ring pairs normalizing and tempering therapy, provide a great organization for subsequent surface hardening press drawings deformation of the 50 % ring equipment inspection after heat treatment method.
2.5 Machining
Initial 2 and a half ring is produced with high energy bolts connecting the ring as a total, the total procedure by drawing a circle Quannei Wai teeth and higher and reduce conclude, and then drawing and machining milling procedure specifications.
two.6 Elimination of processing anxiety
The overall ring annealed to eradicate stress.
two.7 total ring floor hardening
IF along the alveolar tooth floor induction hardening, hardness HRC50 ~ fifty five, effective hardened layer depth 3 ~ 5mm.
2.8 Last inspection
Very first, the detection frequency quenching, the hardness following tempering ring equipment cogging satisfies the specifications of the drawings next, to detect whether the highest outer diameter more substantial dimension D6944 as the deformation 3mm, the mechanical correction required right up until competent Thirdly, tooth and fillet magnetic particle inspection, good quality must meet 2 needs GB/T9444-88 normal demands Lastly, according to the drawings and complex specifications for last inspection.


Organization Profile

Our Benefits

Ep’s item assortment only contains bronze worm gears. The explanation is simple, bronze ensures the greatest sliding and dry managing homes when compared to other resources. The aluminium content also makes certain higher chemical resistance. Worm gears are excellent for constant procedure at high velocity and torque.
