With far more than a thousand girth gears marketed more than the planet CZPT Equipment is a leading provider in the cement and mineral business. And as member of AGMA (American Equipment Makers Affiliation), we do actively consider element in defining the regular for equipment ranking calculations and service aspects. 
We provide girth gears in 3 diverse styles
Fabricated steel
– forged ring
– rolled plate
Cast steel 
Ductile (Nodular) forged iron  
Fabricated gears became a lot more widespread in the earlier and are made with forged steel equipment rim materials and electro welded entire body structure. The rings are made from a total block of large resistance alloy metal. Right after the rough machining of the ring, we carry out hardening and tempering heat treatment in order to improve the mechanical attribute and therefore its appropriate performance.  
Avantages of fabricated girth gears
The cast content construction excludes the threat of inclusions
Construction problems like gas holes, CZPT shrinkage, pin holes, very hot tears, sand and slag inclusions are prevented
Therefore, mend welding of the body structure and e.g. grinding of toothed areas is not needed.
The fabricated producing process excludes the want for styles and risers
Rim materials has greater hardness and larger power than the materials used for the underlying construction (i.e. internet, gussets)
These attributes will minimize the lead time and costs. Fabricated production makes certain a quickly delivery.
This is specifically advantageous in an crisis scenario, where the existing equipment rim is struggling from damage   
Functions

The complex needs of a big CZPT Gear ring:
1) is pretreated before normalizing floor hardening remedy, the hardness must HB210 ~ 250 mechanical efficiency are the supreme strength Rb 690MPa, produce tension Rs 490MPa, elongation D5 eleven%, reduction of region W 25% , influence toughness Ak 30J enamel induction hardened, hardness HRC50 ~ fifty five efficient hardened layer depth 3 ~ 5mm.
two) overall ultrasonic flaw detection, inside high quality ought to meet up with 2 needs GB7233-87 standard demands tooth and fillet magnetic particle inspection, top quality must meet up with 2 requirements GB/T9444-88 standards.
three) Note the casting is not rounded R5 ~ R10.
four) Tooth chamfer at both ends and 1 45b.5) by 2 and a 50 % ring equipment tooth width of each ring CZPT alongside the edge of a complete ring produced with higher energy bolts, blended with the tooth area need to be at the base heart.
2 huge ring equipment manufacturing procedure
2.1 of tough
Steel casting blank is supplied by CITIC Heavy CZPT Co., Ltd. Hefty Forging plant, operate by GB11352-89 regular specifies demands for modeling in accordance to the casting method, smelting, casting, strike packing containers, cleaning, dressing castings. Throughout inspection and acceptance by the drawings and Technical demands for steel blank
Checks, according JB/T6402-92 standards issued right after acceptance
Down method.
2.2 roughing
Crossed by drawing and stay out allowance, alignment, connection, processing both inside and outside the circle, combining encounter milling, drilling and other processes.
two.3 Exploration damage
Overall ultrasonic flaw detection, inside good quality need to meet the 2 requirements of GB7233-87 specifications.
two.4 normalizing pretreatment
Semi-ring pairs normalizing and tempering therapy, offer a great business for subsequent surface area hardening press drawings deformation of the half ring gear inspection right after heat treatment method.
2.5 Machining
Initial 2 and a half ring is created with substantial strength bolts connecting the ring as a whole, the all round procedure by drawing a circle Quannei Wai teeth and higher and decrease stop, and then drawing and machining milling procedure demands.
2.6 Elimination of processing anxiety
The all round ring annealed to get rid of pressure.
two.7 general ring area hardening
IF along the alveolar tooth surface area induction hardening, hardness HRC50 ~ fifty five, successful hardened layer depth 3 ~ 5mm.
two.8 Closing inspection
1st, the detection frequency quenching, the hardness after tempering ring gear cogging meets the specifications of the drawings next, to detect regardless of whether the maximum outer diameter larger size D6944 as the deformation 3mm, the mechanical correction essential until finally certified Thirdly, tooth and fillet magnetic particle inspection, good quality should fulfill 2 requirements GB/T9444-88 standard specifications Last but not least, according to the drawings and complex specifications for ultimate inspection.

The lubricating oil exterior circulation tools of the worm equipment reducer equipment has minimal oil temperature. The worm equipment reducer strategies to traverse its energy. The worm equipment is created of non-ferrous metallic. Learn knowledge worms are normally manufactured of tough steel. As a result, employing a whole lot of warmth in the software, coupled with the influence of the ambient temperature, it is tough to handle the temperature of the reducer. Use within the temperature variety. When the ambient temperature is decrease than 0℃, the functioning temperature of the worm gear reducer need to be managed at -40℃~40℃. It is advised to warmth or use a low freezing level lubricant ahead of the oil is entirely dissolved.
