With a lot more than one thousand girth gears bought above the world CZPT Equipment is a leading supplier in the cement and mineral industry. And as member of AGMA (American Equipment Producers Affiliation), we do actively take element in defining the normal for equipment score calculations and services aspects.
We provide girth gears in 3 diverse designs
Ductile (Nodular) forged iron
Fabricated gears became much more widespread in the previous and are built with cast metal gear rim materials and electro welded physique structure. The rings are produced from a complete block of high resistance alloy metal. After the rough machining of the ring, we carry out hardening and tempering heat treatment method in purchase to boost the mechanical characteristic and as a result its pertinent efficiency.
Avantages of fabricated girth gears
The solid material composition excludes the threat of inclusions
Construction problems like gasoline holes, CZPT shrinkage, pin holes, sizzling tears, sand and slag inclusions are avoided
Therefore, restore welding of the entire body framework and e.g. grinding of toothed regions is not needed.
The fabricated manufacturing treatment excludes the want for designs and risers
Rim materials has larger hardness and increased strength than the material used for the underlying structure (i.e. world wide web, gussets)
These attributes will lessen the direct time and charges. Fabricated producing ensures a quick supply.
This is especially advantageous in an emergency circumstance, the place the present equipment rim is struggling from damage

The technical needs of a big CZPT Gear ring:
one) is pretreated ahead of normalizing surface hardening treatment, the hardness need to HB210 ~ 250 mechanical efficiency are the supreme energy Rb 690MPa, produce stress Rs 490MPa, elongation D5 11%, reduction of area W twenty five% , influence toughness Ak 30J enamel induction hardened, hardness HRC50 ~ 55 efficient hardened layer depth 3 ~ 5mm.
2) all round ultrasonic flaw detection, internal top quality must satisfy 2 requirements GB7233-87 normal specifications tooth and fillet magnetic particle inspection, top quality must satisfy 2 specifications GB/T9444-88 standards.
three) Be aware the casting is not rounded R5 ~ R10.
4) Tooth chamfer at each ends and 1 45b.5) by 2 and a 50 percent ring equipment tooth width of each ring CZPT together the edge of a entire ring made with high power bolts, merged with the tooth area should be at the base centre.
2 big ring equipment production process
2.1 of tough
Metal casting blank is presented by CITIC Large CZPT Co., Ltd. Large Forging plant, run by GB11352-89 regular specifies demands for modeling according to the casting process, smelting, casting, strike packing containers, cleansing, dressing castings. Throughout inspection and acceptance by the drawings and Technical needs for steel blank
Checks, in accordance JB/T6402-92 requirements issued right after acceptance
Down process.
two.2 roughing
Crossed by drawing and keep out allowance, alignment, connection, processing each within and exterior the circle, combining encounter milling, drilling and other procedures.
two.3 Exploration harm
General ultrasonic flaw detection, inner top quality need to meet the 2 demands of GB7233-87 standards.
two.4 normalizing pretreatment
Semi-ring pairs normalizing and tempering remedy, provide a good organization for subsequent surface area hardening push drawings deformation of the 50 % ring gear inspection after warmth therapy.
2.5 Machining
First 2 and a half ring is made with higher energy bolts connecting the ring as a whole, the all round approach by drawing a circle Quannei Wai tooth and higher and lower finish, and then drawing and machining milling method specifications.
two.6 Elimination of processing tension
The all round ring annealed to eliminate pressure.

2.8 Final inspection
First, the detection frequency quenching, the hardness soon after tempering ring equipment cogging meets the specifications of the drawings secondly, to detect no matter whether the highest outer diameter more substantial dimensions D6944 as the deformation 3mm, the mechanical correction necessary until finally competent Thirdly, tooth and fillet magnetic particle inspection, quality ought to fulfill 2 demands GB/T9444-88 standard needs Last but not least, in accordance to the drawings and technological requirements for last inspection.
After Product sales Services
The generate aspect is a worm. In buy to blend the wheel/worm into a worm equipment, it must be ensured that the heart length is equal and the transmission ratio is equal. Heart distances are offered from stock in tiny steps between 17mm and 80mm. Every single center length has numerous gear ratios. Ep worm gears are suited for the generation of worm drives with a shaft angle of 90°. Making use of a worm generate, very massive reduction ratios (up to 100:1) can be reached.
